Blended and online learning is growing, and self-regulated learning is becoming more relevant. Most often, students struggle with organizing their own learning processes, lose focus or procrastinate. Keeping learners motivated and engaged can be a real challenge. Therefore, we present gamified chatbots as a potential solution. On the one hand, chatbots can provide a more engaging learning experience. On the other hand, gamification can provide motivational incentives to keep learners engaged and motivated. So far, not many studies have elaborated on how gamification can be effectively used to make a chatbot interaction more engaging or improve the learning experience. This study uses an experimental approach to distinguish how a combination of badges and a progress bar can support and motivate learners to stay engaged with their learning activities. We elaborate on the effects of gamified chatbots and support practitioners with guidance on how to design gamified chatbots in education.

This paper presents a methodological framework for training, self-optimising, and self-organising surrogate models to approximate and speed up multiobjective optimisation of technical systems based on multiphysics simulations. At the hand of two real-world datasets, we illustrate that surrogate models can be trained on relatively small amounts of data to approximate the underlying simulations accurately. Including explainable AI techniques allow for highlighting feature relevancy or dependencies and supporting the possible extension of the used datasets. One of the datasets was created for this paper and is made publicly available for the broader scientific community. Extensive experiments combine four machine learning and deep learning algorithms with an evolutionary optimisation algorithm. The performance of the combined training and optimisation pipeline is evaluated by verifying the generated Pareto-optimal results using the ground truth simulations. The results from our pipeline and a comprehensive evaluation strategy show the potential for efficiently acquiring solution candidates in multiobjective optimisation tasks by reducing the number of simulations and conserving a higher prediction accuracy, i.e., with a MAPE score under 5% for one of the presented use cases.
An Efficient Multi Quantile Regression Network with Ad Hoc Prevention of Quantile Crossing. Decke, Jens; Jenß, Arne; Sick, Bernhard; Gruhl, Christian. In International Conference on Architecture of Computing Systems (ARCS). Springer, 2024.
- [ Abstract ]
- [ BibSonomy-Post ]
This article presents the Sorting Composite Quantile Regression Neural Network (SCQRNN), an advanced quantile regression model designed to prevent quantile crossing and enhance computational efficiency. Integrating ad hoc sorting in training, the SCQRNN ensures non-intersecting quantiles, boosting model reliability and interpretability. We demonstrate that the SCQRNN not only prevents quantile crossing and reduces computational complexity but also achieves faster convergence than traditional models. This advancement meets the requirements of high-performance computing for sustainable, accurate computation. In organic computing, the SCQRNN enhances self-aware systems with predictive uncertainties, enriching applications across finance, meteorology, climate science, and engineering.

Ausgehend von der Beobachtung, dass gegenwärtige Herausforderungen der Datenökonomie neben der angemessenen Verwendung von Daten auch Aspekte der gerechten Verteilung von Erlösen, die Manipulation durch Algorithmen oder die Beeinflussung der politischen Meinungsbildung durch Plattformen betreffen, lotet das vorliegende White Paper Möglichkeiten der fairen Gestaltung datenökonomischer Geschäftsmodelle aus. Die erarbeiteten Instrumente und Analysen zur Unterstützung einer fairen Geschäftsmodellgestaltung basieren auf Ergebnissen des vom BMBF geförderten Projekts „Faire digitale Dienste: Ko-Valuation in der Gestaltung datenökonomischer Geschäftsmodelle (FAIRDIENSTE)“. Um ein analytisch gehaltvolles Fairness-Verständnis zu entwickeln, das auch für die konkrete datenökonomische Gestaltungspraxis innovative und wirtschaftlich tragfähige Alternativen zu gegenwärtigen Geschäftsmodellen freizulegen vermag, wurden in FAIRDIENSTE verschiedene Ansätze der kooperativen Wertvermittlung (im Folgenden auch „Ko-Valuation“) erprobt, die wir als Verrechnung, Design und Kultivierung bezeichnen: Erstens wurde untersucht, inwiefern sich unterschiedliche Werte in eine ökonomische Sprache der Preise übersetzen und fair verrechnen lassen (Verrechnung). Zweitens wurde herausgearbeitet, wie Wertkonflikte durch technische und regulative Designs kanalisiert werden können (Design). Drittens wurde geprüft, inwiefern die öffentliche Aushandlung von Wertkonflikten, z.B. über Social-Media-Elemente, gefördert werden kann, um zu einer Kultur der Fairness unter den Nutzerinnen und Nutzern beizutragen (Kultivierung). Diese Perspektiven wurden anhand der Fairness-Herausforderungen des digitalen Journalismus geschärft und auf ihre Tragfähigkeit geprüft. Darüber hinaus beanspruchen die folgenden Überlegungen und Instrumente zur fairen Geschäftsmodellgestaltung aber auch auf andere gesellschaftliche Domänen anwendbar zu sein.

Agile leadership (AL) is essential for leading agile transformations. So far, a conceptualization of AL is still lacking. To investigate its core characteristics, we conduct an exploratory single case study. Our study examines a senior executive training program within a young European automotive software company, with the objective of establishing AL throughout the organization. Our study’s primary findings reveal that AL can be categorized into five perspectives: person-based, purpose-based, result-based, position-based, and process-based. Agile leaders are humble, adaptable, visionary, and engaged. AL focuses on aligning employees with a clear vision, fostering a learning organization, increasing transparency, and establishing decision-making in teams. It is practiced by executives, agile accountabilities, and team members. Agile leaders operate as experimenters, collaborators, facilitators, enablers, and resilient leaders. Our findings provide a foundational basis for organizations to implement AL, thereby enhancing their adaptability and overall success.

The operating environment of a highly automated vehicle is subject to change, e.g., weather, illumination, or the scenario containing different objects and other participants in which the highly automated vehicle has to navigate its passengers safely. These situations must be considered when developing and validating highly automated driving functions. This already poses a problem for training and evaluating deep learning models because without the costly labeling of thousands of recordings, not knowing whether the data contains relevant, interesting data for further model training, it is a guess under which conditions and situations the model performs poorly. For this purpose, we present corner case criteria based on the predictive uncertainty. With our corner case criteria, we are able to detect uncertainty-based corner cases of an object instance segmentation model without relying on ground truth (GT) data. We evaluated each corner case criterion using the COCO and the NuImages dataset to analyze the potential of our approach. We also provide a corner case decision function that allows us to distinguish each object into True Positive (TP), localization and/or classification corner case, or False Positive (FP). We also present our first results of an iterative training cycle that outperforms the baseline and where the data added to the training dataset is selected based on the corner case decision function.

Artificial intelligence (AI) applications pave the way for innovations in the healthcare (HC) industry. However, their adoption in HC organizations is still nascent as organizations often face a fragmented and incomplete picture of how they can capture the value of AI applications on a managerial level. To overcome adoption hurdles, HC organizations would benefit from understanding how they can capture AI applications’ potential. We conduct a comprehensive systematic literature review and 11 semi-structured expert interviews to identify, systematize, and describe 15 business objectives that translate into six value propositions of AI applications in HC. Our results demonstrate that AI applications can have several business objectives converging into risk-reduced patient care, advanced patient care, self-management, process acceleration, resource optimization, and knowledge discovery. We contribute to the literature by extending research on value creation mechanisms of AI to the HC context and guiding HC organizations in evaluating their AI applications or those of the competition on a managerial level, to assess AI investment decisions, and to align their AI application portfolio towards an overarching strategy.

Spatial-Temporal Attention Graph Neural Network with Uncertainty Estimation for Remaining Useful Life Prediction. Huang, Zhixin; Nivarthi, Chandana Priya; Gruhl, Christian; Sick, Bernhard. In International Joint Conference on Neural Networks (IJCNN). IEEE, 2024.
- [ Abstract ]
- [ BibSonomy-Post ]
In the increasingly complex industrial system health management domain, accurate prediction of remaining useful life plays an essential role. This paper analyzes the methods to improve the predictive performance of remaining useful life from three aspects: optimizing model structures, augmenting uncertainty estimation in predictions, and transitioning normalization methods. Based on our analysis, we propose a novel model, the Uncertainty Spatial-Temporal Attention Graph Neural Network (USTAGNN), which consists of three primary components: sensor graph construction, a spatio-temporal feature extractor, and a probabilistic prediction module. The feature extractor leverages graph neural networks and temporal convolutional networks as a foundation to extract spatial and temporal features, further enhanced by attention mechanisms, spectral normalization, and residual connections to bolster its distance awareness. Following extensive experimental comparisons, we utilized the parameter-driven dynamic adjacency matrix for sensor graph construction and the deep kernel Gaussian process for precise uncertainty estimation. USTAGNN tries to resolve issues not thoroughly addressed in existing research, such as comparative analyses of sensor graph construction methods, accurate uncertainty estimation, and the model’s generalization under different preprocessing conditions. The proposed model demonstrated state-of-the-art performance on various subsets of the C-MAPSS dataset, achieving up to a 35.9% improvement in prediction score.

The rising number of financial frauds inflicted in the last year more than 800 billion USD in damages on the global economy. Although financial institutions possess advanced AI systems for fraud detection, the time required to accumulate a sufficient volume of fraudulent data for training models creates a costly vulnerability. Combined with the inability to share fraud detection training data among institutions due to data and privacy regulations, this poses a major challenge. To address this issue, we propose the concept of a synthetic data-sharing ecosystem platform (FinDEx). This platform ensures data anonymity by generating synthesized training data based on each institution's fraud detection datasets. Various synthetic data generation techniques are employed to rapidly construct a shared dataset for all ecosystem members. Using design science research, this paper leverages insights from financial fraud detection literature, data sharing practices, and modular systems theory to derive design knowledge for the platform architecture. Furthermore, the feasibility of using different data generation algorithms such as generative adversarial networks, variational auto encoder and Gaussian mixture model was evaluated and different methods for the integration of synthetic data into the training procedure were tested. Thus, contributing to the theory at the intersection between fraud detection and data sharing and providing practitioners with guidelines on how to design such systems.

Für die Montage von komplexen Baugruppen soll ein Schulungsangebot entwickelt werden, welches auch ohne Sprachbarriere ein niedrigschwelliges Anlernen neuer Arbeiter ermöglicht. In der hier vorgestellten Studie wurden zwei Arten von Montagetrainings für die Montage einer realen Baugruppe eines mittelständischen Unternehmens verglichen. Eine Gruppe wurde in einer VR-Trainingssimulation geschult. Die Kontrollgruppe wurde mit einem Video aus der Egoperspektive der VR-Anwendung trainiert. Dabei wurden die Gebrauchstauglichkeit (SUS) und die Beanspruchung (NASA-TLX) bei der Verwendung der Anwendungen getestet. Anschließend wurde die komplexe Baugruppe an einem Montagearbeitsplatz montiert, wobei die benötigte Zeit und die gemachten Fehler protokolliert wurden.
Multi-Task Representation Learning with Temporal Attention for Zero-Shot Time Series Anomaly Detection. Nivarthi, Chandana Priya; Huang, Zhixin; Gruhl, Christian; Sick, Bernhard. In International Joint Conference on Neural Networks (IJCNN). IEEE, 2024.
- [ Abstract ]
- [ BibSonomy-Post ]
Ensuring the reliability of critical industrial systems across various sectors is crucial. It is essential to detect deviations from regular behaviour to mitigate disruptions and preserve infrastructure integrity. However, accurately labelling anomaly datasets is challenging due to their rarity and manual annotation subjectivity. The conventional approach of training separate models for each dataset entity further complicates model development. This paper presents a novel Multi-task Learning framework combining LSTM Autoencoder with temporal attention mechanism (MTL-LATAM) for effective time series anomaly detection. Multitask learning models improve adaptability and generalizability, leading to reduced runtime and compute power while supporting zero-shot evaluation. These models offer flexibility in detecting emerging anomalies. Additionally, we introduce a dynamic thresholding mechanism to incorporate temporal context for anomaly detection and provide visualizations of attention weights to enhance interpretability. The study compares MTL- LATAM, with other multi-task models, evaluates multi-task versus single-task models and assesses the performance of the proposed frame- work in zero-shot learning scenarios. The findings indicate MTL- LATAM’s effectiveness across real-world and open-source datasets, achieving 95% and 97% task synergy. The results underscore the superior performance of multi-task models in zero-shot tasks compared to individual models trained exclusively on their respective datasets.

Customer support service employees are facing an increased workload, while artificial intelligence (AI) appears to possess the potential to change the way we work. With the advent of modern types of generative AI, new opportunities to augment frontline service employees have emerged. However, little is known about how to integrate generative AI in customer support service organizations and purposefully change service employee work routines. Following multi-method qualitative research, we performed a literature review, conducted workshops, and interviewed IT support agents, managers, and AI experts. Thereby, we examine AI augmentation for frontline service employees in the context of IT support to carve out where and how GenAI can be leveraged to develop more efficient and higher-quality customer support. Our resulting framework reveals that especially adapting solutions and retaining knowledge is subject to a high degree of AI augmentation.

While chatbots can be implemented with very little effort, scaling and maintaining chatbots remains a challenge. This is crucial in knowledge-intensive customer service like IT support, where domain knowledge must stay current with the evolving IT landscape. Following design science research, we derive design principles for a generative AI (GPT4) enabled textual training data creation and curation system (T²C²) as part of a new class of systems – bot delegation systems. For the design of T²C², chatbot and domain expert viewpoints are integrated. We evaluate two instances of T²C², each with distinct degrees of human-ai delegation where employees act both as creators and curators of training data. The paper’s theoretical contribution is two-fold: (1) we present a novel kernel theory that represents the material characteristics of bot delegation systems by contextualizing the IS delegation framework to the self-determination theory; (2) the design and evaluation of T²C² as the built-and-evaluated artifact.

The fast-paced acceleration of digitalization requires extensive re-&upskilling, impacting a significant proportion of jobs worldwide. Technology-mediated learning platforms have become instrumental in addressing these efforts, as they can analyze platform data to provide personalized learning journeys. Such personalization is expected to increase employees’ empowerment, job satisfaction, and learning outcomes. However, the challenge lies in efficiently deploying these opportunities using novel technologies, prompting questions about the design and analysis of generating personalized learning paths in organizational learning. We, therefore, analyze and classify recent research on personalized learning paths into four major concepts (learning context, data, interface, and adaptation) with ten dimensions and 34 characteristics. Six expert interviews validate the taxonomy’s use and outline three exemplary use cases, undermining its feasibility. Information Systems researchers can use our taxonomy to develop theoretical models to study the effectiveness of personalized learning paths in intra-organizational re-&upskilling.

Conversational agents (CAs) have come a long way from their first appearance in the 1960s to today's generative models. Continuous technological advancements such as statistical computing and large language models allow for an increasingly natural and effortless interaction, as well as domain-agnostic deployment opportunities. Ultimately, this evolution begs multiple questions: How have technical capabilities developed? How is the nature of work changed through humans' interaction with conversational agents? How has research framed dominant perceptions and depictions of such agents? And what is the path forward? To address these questions, we conducted a bibliometric study including over 5000 research articles on CAs. Based on a systematic analysis of keywords, topics, and author networks, we derive "five waves of CA research" that describe the past, present, and potential future of research on CAs. Our results highlight fundamental technical evolutions and theoretical paradigms in CA research. Therefore, we discuss the moderating role of big technologies, and novel technological advancements like OpenAI GPT or BLOOM NLU that mark the next frontier of CA research. We contribute to theory by laying out central research streams in CA research, and offer practical implications by highlighting the design and deployment opportunities of CAs.

In der hier vorgestellten Laborstudie wurde ein Smart Public Display mit personalisierten Fahrgastinformationen des öffentlichen Personennahverkehrs mit dem Stand der Technik, einem Public Display mit allgemeinen Fahrgastinformationen nahegelegener Haltestellen, verglichen. Unter Einbezug des Abstands einer umstehenden Person wurde die Technologieakzeptanz mit dem TUI-, die Gebrauchstauglichkeit mit dem SUS- und die Nutzererfahrung mit dem UEQ-Fragebogen erhoben. Die Ergebnisse zur Technologieakzeptanz zeigen keine signifikanten Unterschiede. Hinsichtlich der Gebrauchstauglichkeit und Nutzererfahrung deuten die Unterschiede darauf hin, dass Weiterentwicklungspotential, aber auch ein Mehrwert des Smart Public Displays mit personalisierten Fahrgastinforma-tionen gegenüber dem Public Display bestehen.

Theory: Argumentation is crucial for all academic disciplines. Nevertheless, a lack of argumentation skills among students is evident. Two core aspects of argumentation are the recognition of argument structures (e.g., backing up claims with premises, according to the Toulmin model) and the recognition of fallacies. As both aspects may be related to content knowledge, students studying different subjects might exhibit different argumentation skills depending on whether the content is drawn from their own or from a foreign subject. Therefore, we developed an instrument to measure the recognition of both argument structures and fallacies among the groups of preservice teachers and business economics students in both their respective domains (pedagogy and economics), and a neutral domain (sustainability). For the recognition of fallacies, we distinguished between congruent and incongruent fallacies. In congruent fallacies, the two aspects of argument quality, i.e., deductive validity and inductive strength, provide converging evidence against high argument quality. In incongruent fallacies, these two aspects diverge. Based on dual process theories, we expected to observe differences in the recognition of congruent and incongruent fallacies. Aims: We investigated whether these two abilities are domain-specific and whether the recognition of fallacies depends on the congruence of two aspects of argument quality. Methods: 267 preservice teachers and 56 business economics students participated in the study. For the recognition of argument structures, participants assigned the five statements constituting one argument to the corresponding component according to the Toulmin model. For the recognition of fallacies, we created arguments and incorporated a common fallacy into some of them: formal fallacy, overgeneralization, irrelevance, or circularity. Participants rated whether the argument was cogent or not, which was followed by a brief justification. Results: Domain specificity could not be found for either of both abilities. For the recognition of fallacies, two dimensions were found: a congruent dimension (formal fallacies and overgeneralizations) and an incongruent dimension (irrelevance and circularity). Discussion: The instrument measures the recognition of both argument structures and fallacies in these two groups across domains. The recognition of fallacies differs depending on whether the deductive validity and the inductive strength of the argument are equally indicative of argument quality or not.

The increasing environmental pollution and rising global energy demands require the rapid development of novel and sustainable traction machines from urban transport up to large-scale transport vehicles. The optimisation of the development cycle of electrical traction machines plays a vital role in sustainable mobility. Still, developers have to face the difficulty of analysing time-consuming multiphysics simulations to assess the performance of many prototype variants. Accelerating this process involves implementing machine learning-supported strategies that can effectively acquire results and predictions about the performance and efficiency of prototypes in an iterative optimisation process and detect possible issues during the experimental procedure. The following research project streamlines the development cycle by identifying and presenting multiple strategies for applying and evaluating machine learning and deep learning techniques in different stages and areas in the development cycle including self-optimisation and self-adaptation capabilities. By implementing these strategies, the optimisation process can be further improved and become more efficient and robust, reducing the time and cost required for testing and validation. Therefore, this proposal addresses two application areas. The first area consists of the supported machine learning motor performance prediction at the topology design and optimisation stage of structural components. The second area corresponds to the machine learning-supported experimental evaluation process of prototypes at desired test benches.

Splitting of sequential data, such as videos and time series, is an essential step in various data analysis tasks, including object tracking and anomaly detection. However, splitting sequential data presents a variety of challenges that can impact the accuracy and reliability of subsequent analyses. This concept article examines the challenges associated with splitting sequential data, including data acquisition, data representation, split ratio selection, setting up quality criteria, and choosing suitable selection strategies. We explore these challenges through two real-world examples: motor test benches and particle tracking in liquids.

In safety-critical applications such as automated driving, perception errors may create an imminent risk to vulnerable road users (VRU). To mitigate the occurrence of unexpected and potentially dangerous situations, so-called corner cases, perception models are trained on a huge amount of data. However, the models are typically evaluated using task-agnostic metrics, which do not reflect the severity of safety-critical misdetections. Consequently, misdetections with particular relevance for the safe driving task should entail a more severe penalty during evaluation to pinpoint corner cases in large-scale datasets. In this work, we propose a novel metric IoUw that exploits relevance on the pixel level of the semantic segmentation output to extend the notion of the intersection over union (IoU) by emphasizing small areas of an image affected by corner cases. We (i) employ IoUw to measure the effect of pre-defined relevance criteria on the segmentation evaluation, and (ii) use the relevance-adapted IoUw to refine the identification of corner cases. In our experiments, we investigate vision-based relevance criteria and physical attributes as per-pixel criticality to factor in the imminent risk, showing that IoUw precisely accentuates the relevance of corner cases.

Abstract The effects of selection on an organism's genome are hard to detect on small spatial scales, as gene flow can swamp signatures of local adaptation. Therefore, most genome scans to detect signatures of environmental selection are performed on large spatial scales; however, divergent selection on the local scale (e.g. between contrasting soil conditions) has also been demonstrated, in particular for herbaceous plants. Here, we hypothesised that in topographically complex landscapes, microenvironment variability is strong enough to leave a selective footprint in the genomes of long-lived organisms. To test this, we investigated paired south- versus north-facing Pinus pinaster stands on the local scale, with trees growing in close vicinity (≤820 m distance between paired south- and north-facing stands), in a Mediterranean mountain area. While trees on north-facing slopes experience less radiation, trees on south-facing slopes suffer from especially harsh conditions, particularly during the dry summer season. Two outlier analyses consistently revealed five putatively adaptive loci (out of 4034), in candidate genes two of which encoded non-synonymous substitutions. Additionally, one locus showed consistent allele frequency differences in all three stand pairs indicating divergent selection despite high gene flow on the local scale. Permutation tests demonstrated that our findings were robust. Functional annotation of these candidate genes revealed biological functions related to abiotic stress response, such as water availability, in other plant species. Synthesis. Our study highlights how divergent selection in heterogeneous microenvironments shapes and maintains the functional genetic variation within populations of long-lived forest tree species, being the first to focus on adaptive genetic divergence between south- and north-facing slopes within continuous forest stands. This is especially relevant in the current context of climate change, as this variation is at the base of plant population responses to future climate.

In this work, we apply deep active learning to the field of design optimization to reduce the number of computationally expensive numerical simulations widely used in industry and engineering. We are interested in optimizing the design of structural components, where a set of parameters describes the shape. If we can predict the performance based on these parameters and consider only the promising candidates for simulation, there is an enormous potential for saving computing power. We present two query strategies for self-optimization to reduce the computational cost in multi-objective design optimization problems. Our proposed methodology provides an intuitive approach that is easy to apply, offers significant improvements over random sampling, and circumvents the need for uncertainty estimation. We evaluate our strategies on a large dataset from the domain of fluid dynamics and introduce two new evaluation metrics to determine the model's performance. Findings from our evaluation highlights the effectiveness of our query strategies in accelerating design optimization. Furthermore, the introduced method is easily transferable to other self-optimization problems in industry and engineering.

Objective: To assess the effect of the toothbrush handle on video-observed toothbrushing behaviour and toothbrushing effectiveness Methods: This is a randomized counterbalanced cross-over study. N = 50 university students brushed their teeth at two occasions, one week apart, using either a commercial ergonomically designed manual toothbrush (MT) or Brushalyze V1 (BV1), a manual toothbrush with a thick cylindrical handle without any specific ergonomic features. Brushing behaviour was video-analysed. Plaque was assessed at the second occasion immediately after brushing. Participants directly compared the two brushes regarding their handling and compared them to the brushed they used at home. Results: The study participants found the BV1 significantly more cumbersome than the M1 or their brush at home. (p < 0.05). However, correlation analyses revealed a strong consistency of brushing behavior with the two brushes (0.71 < r < 0.91). Means differed only slightly (all d < 0.36). These differences became statistically significant only for the brushing time at inner surfaces (d = 0.31 p = 0.03) and horizontal movements at inner surfaces (d = 0.35, p = 0.02). Plaque levels at the gingival margins did not differ while slightly more plaque persisted at the more coronal aspects of the crown after brushing with BV1 (d = 0.592; p 0.042) Discussion: The results of the study indicate that the brushing handle does not play a major role in brushing behavior or brushing effectiveness.

The goals of design science research (DSR) projects are to generate novel and useful artifacts and to produce rigorous and generalizable design knowledge. Often, DSR projects are conducted in collaborative, interdisciplinary project teams. Different disciplinary approaches to codifying design knowledge result in challenging project interactions. To study this situation, we analyze design knowledge codification in interdisciplinary teams over time. We gain insights from a survey of recent DSR papers that have been published in the AIS Senior Scholars’ Basket. We then present a detailed case study of a longitudinal project that brought to light issues of sharing design knowledge across disciplinary borders. Drawing from the survey and case study, we provide actionable guidance on how to effectively codify and share design knowledge to support researchers and practitioners to build useful artifacts and to make interdisciplinary design knowledge contributions reusable and applicable.

The COVID-19 pandemic has brought about major changes in digitization in many areas of life and professions. New areas were digitized almost overnight, the school system in Germany was no exception leading to a demand for videoconferencing tools and communication platforms. These technologies have many different functionalities that need to be discovered, explored, and exploited by the user. Given the disruptive events that the COVID pandemic brought to us, this paper aims to shed light on how the dynamics of discovery, exploration, and exploitation unfolds. We use a functional affordance theory perspective to analyze and understand how user learn to use new technologies. To do this, we conducted an exploratory case-study-based research design including interviews with teachers from various schools to analyze how they appropriate new technologies to develop an explanatory theoretical model.

Diversity is a term that is broadly used and challenging for informatics research, development and education. Diversity concerns may relate to unequal participation, knowledge and methodology, curricula, institutional planning etc. For a lot of these areas, measures, guidelines and best practices on diversity awareness exist. A systemic, sustainable impact of diversity measures on informatics is still largely missing. In this paper I explore what working with diversity and gender concepts in informatics entails, what the main challenges are and provide thoughts for improvement. The paper includes definitions of diversity and intersectionality, reflections on the disciplinary basis of informatics and practical implications of integrating diversity in informatics research and development. In the final part, two concepts from the social sciences and the humanities, the notion of “third space”/hybridity and the notion of “feminist ethics of care”, serve as a lens to foster more sustainable ways of working with diversity in informatics.

Given a formal context, an ordinal factor is a subset of its incidence relation that forms a chain in the concept lattice, i.e., a part of the dataset that corresponds to a linear order. To visualize the data in a formal context, Ganter and Glodeanu proposed a biplot based on two ordinal factors. For the biplot to be useful, it is important that these factors comprise as much data points as possible, i.e., that they cover a large part of the incidence relation. In this work, we investigate such ordinal two-factorizations. First, we investigate for formal contexts that omit ordinal two-factorizations the disjointness of the two factors. Then, we show that deciding on the existence of two-factorizations of a given size is an {\$$}{\$$}{\backslash}textsf{\{}NP{\}}{\$$}{\$$}NP-complete problem which makes computing maximal factorizations computationally expensive. Finally, we provide the algorithm Ord2Factor that allows us to compute large ordinal two-factorizations.

Although the idea of low code development is not new, the market for these oftentimes platform-based development approaches is exponentially growing. Especially factors such as increasing affinity for technology development across all user groups, consumerization of development, and advancing digitalization are opening a new target group for the low code movement. The broad application possibilities of low code, as well as the benefits, are therefore getting more important for businesses. Especially for small and medium-sized enterprises (SMEs), low code constitutes a promising avenue to survive and succeed in the rapidly changing world. However, a clear understanding regarding the application of this paradigm of software development in SMEs is still missing. To provide a coherent understanding of the phenomenon low code in SMEs, we review extant literature and conduct interviews, identifying potential application domains and conceptualizing the benefits and challenges of low code from a holistic perspective.
Leveraging Low Code Development of Smart Personal Assistants: An Integrated Design Approach with the SPADE Method. Elshan, Edona; Ebel, Philipp Alexander; Söllner, Matthias; Leimeister, Jan Marco. In Journal of Management Information Systems (JMIS), 40(1), pp. 96–129. 2023.

Smart personal assistants (SPAs) promise individualized user interactions owing to their varying interaction possibilities, knowledgeability, and human-like behaviors. To support the widespread adoption and use of SPAs, organizations such as Google or Amazon provide low code environments that support the development of SPAs (e.g., for Google Home or Amazon’s Alexa). These so-called low code platforms enable domain experts (e.g., business users without programming skills or experience) to develop SPAs for their purposes. However, using these platforms alone does not guarantee a useful and good conversation with novel SPAs due to non-intuitive design choices. Following a design science research approach, we propose the Smart Personal Assistant for Domain Experts (SPADE) method to address the missing link. This method supports domain experts in the development and contextualization of sophisticated SPAs for various application scenarios and focuses especially on conversational and anthropomorphic design steps. Our proof of concept and proof of value results show that SPADE is useful for supporting domain experts to create effective SPAs in different domains beyond private set-ups.

Recent years have seen a growing adoption of Low Code Development Platforms (LCDPs) in organizations. The increasing affinity for technology development across all user groups, consumerization of development, and advancing digitalization are opening up a new target group for the low code movement. This change in software development allows bottom-up user innovators within a company to leverage their domain knowledge and quickly deploy much-needed digital services. However, a clear understanding of this paradigm of software development in organizations and the influence on end-user acceptance is still missing. In this paper, we present the results of an interview study conducted with 18 LCDP experts and discuss the implications of our findings, highlighting the role of LCDPs and context in bottom-up innovation as well as user-centricity. Our research contributes to the literature on LCDPs and offers valuable insights for organizations looking to leverage their workforce's innovative potential.
On the Reliability of Automated Analysis of Fracture Surfaces Using a Novel Computer Vision-Based Tool.

Fracture surface analysis is of utmost importance with respect to structural integrity of metallic materials. This especially holds true for additively manufactured materials. Despite an increasing trend of automatization of testing methods, the analysis and classification of fatigue fracture surface images is commonly done manually by experts. Although this leads to correct results in most cases, it has several disadvantages, e.g., the need of a huge knowledge base to interpret images correctly. In present work, an unsupervised tool for analysis of overview images of fatigue fracture surface images is developed to support nonexperienced users to identify the origin of the fracture. The tool is developed using fracture surface images of additively manufactured Ti6Al4V specimens fatigued in the high-cycle-fatigue regime and is based on the identification of river marks. Several recording parameters seem to have no significant influence on the results as long as preprocessing settings are adapted. Moreover, it is possible to analyze images of other materials with the tool as long as the fracture surfaces contain river marks. However, special features like multiple origins or origins located in direct vicinity to the surface, e.g., caused by increased plastic strains, require a further tool development or alternative approaches.

Current approaches to the design and development of digital business models (DBMs) overlook the multiple, and sometimes conflicting, logics of actors with which the focal firm seeks to co-create value. The lack of integrating stakeholders’ logics into DBMs has potentially detrimental and unintended ethical and social consequences. By collaboratively conducting an action research project with a digital publisher and drawing on participatory and value-sensitive design principles, we develop a novel approach for designing DBMs that integrates actors’ multiple logics by design. We contribute to literature by introducing a new approach highlighting DBMs’ inherent social aspects and furthering our understanding of multiple logics’ role in DBMs. Practitioners gain a concrete DBM design method preempting conflict.

After facing the COVID-19 pandemic, organizations request their employees to work from home permanently. For an organization, this provides positive benefits such as reducing costs for rent. From an employee perspective, working from home can cause a feeling of isolation towards co-workers and lower attachment to an organization. One way to counteract this problem is to transfer the office to the digital world, especially spurred by the metaverse discussion to represent processes of our real world in digital environments that allow us to do everything in the same way digitally as we are doing in the real world. In this paper, we present a theoretical model for conducting a 2x2 between-subject experiment to analyze how digital real-world meeting experiences influence team attachment and organizational commitment. We contribute to theories such as the need of belonging and transfer them to digital environments and provide practical implications for designing digital offices.

In an age of lifelong learning, it is important that adult learners can effectively use their motivation and resources to reach their learning goals. In conversation, coaches can intervene to promote learning goal attainment by using behavioural change techniques (BCTs). In a coaching chatbot, such techniques can be ordered in an established, structured way to good effect. With recent technological advances, chatbot responses can be generated adaptively; this means that BCTs can be applied in an adaptive but less structured way. It is yet unclear whether this latter form of configuring coaching interventions is viable, how they compare to more established structured interventions, and whether both methods can be combined. For the purpose of answering this, we propose a 2x2 experimental design with the two intervention types as factors and goal attainment as the dependent variable. Results will indicate avenues for automating skilled conversation including choice of technology.

Applications using machine learning (ML), such as highly autonomous driving, depend highly on the performance of the ML model. The data amount and quality used for model training and validation are crucial. If the model cannot detect and interpret a new, rare, or perhaps dangerous situation, often referred to as a corner case, we will likely blame the data for not being good enough or too small in number. However, the implemented ML model and its associated architecture also influence the behavior. Therefore, the occurrence of prediction errors resulting from the ML model itself is not surprising. This work addresses a corner case definition from an ML model's perspective to determine which aspects must be considered. To achieve this goal, we present an overview of properties for corner cases that are beneficial for the description, explanation, reproduction, or synthetic generation of corner cases. To define ML corner cases, we review different considerations in the literature and summarize them in a general description and mathematical formulation, whereby the expected relevance-weighted loss is the key to distinguishing corner cases from common data. Moreover, we show how to operationalize the corner case characteristics to determine the value of a corner case. To conclude, we present the extended taxonomy for ML corner cases by adding the input, model, and deployment levels, considering the influence of the corner case properties.

Context information provided along with a dataset can be very helpful for solving a problem because the additional knowledge is already available and does not need to be extracted. Moreover, the context indicates how diverse a dataset is, i.e., how many samples per context category are available to train and test machine learning (ML) models. In this article, we present context annotations for the BDD100k image dataset. The annotations comprise, for instance, information about daytime, road condition (dry/wet), and dirt on the windshield. Sometimes, no or only little data are available for unique or rare combinations of these context attributes. However, data that matches these context conditions is crucial when discussing corner cases: Firstly, most ML models, e.g., object detectors, are not trained on such data, which leads to the assumption that they will perform poorly in those situations. Secondly, data containing corner cases are required for validating ML models. With this in mind, separate ML models dedicated to context detection are useful for expanding the training set with additional data of special interest, such as corner cases.

Lattices and their order diagrams are an essential tool for communicating knowledge and insights about data. This is in particular true when applying Formal Concept Analysis. Such representations, however, are difficult to comprehend by untrained users and in general in cases where lattices are large. We tackle this problem by automatically generating textual explanations for lattices using standard scales. Our method is based on the general notion of ordinal motifs in lattices for the special case of standard scales. We show the computational complexity of identifying a small number of standard scales that cover most of the lattice structure. For these, we provide textual explanation templates, which can be applied to any occurrence of a scale in any data domain. These templates are derived using principles from human-computer interaction and allow for a comprehensive textual explanation of lattices. We demonstrate our approach on the spices planner data set, which is a medium sized formal context comprised of fifty-six meals (objects) and thirty-seven spices (attributes). The resulting 531 formal concepts can be covered by means of about 100 standard scales.

Lattices are a commonly used structure for the representation and analysis of relational and ontological knowledge. In particular, the analysis of these requires a decomposition of a large and high-dimensional lattice into a set of understandably large parts. With the present work we propose /ordinal motifs/ as analytical units of meaning. We study these ordinal substructures (or standard scales) through (full) scale-measures of formal contexts from the field of formal concept analysis. We show that the underlying decision problems are NP-complete and provide results on how one can incrementally identify ordinal motifs to save computational effort. Accompanying our theoretical results, we demonstrate how ordinal motifs can be leveraged to retrieve basic meaning from a medium sized ordinal data set.

Spatio-Temporal Attention Graph Neural Network for Remaining Useful Life Prediction. Huang, Zhixin; He, Yujiang; Sick, Bernhard. In Computational Science and Computational Intelligence (CSCI). IEEE, 2023.
- [ Abstract ]
- [ BibSonomy-Post ]
RUL prediction plays a crucial role in the health management of industrial systems. Given the increasing complexity of systems, data-driven predictive models have attracted significant research interest. Upon reviewing the existing literature, it appears that many studies either do not fully integrate both spatial and temporal features or employ only a single attention mechanism. Furthermore, there seems to be inconsistency in the choice of data normalization methods, particularly concerning operating conditions, which might influence predictive performance. To bridge these observations, this study presents the Spatio-Temporal Attention Graph Neural Network. Our model combines graph neural networks and temporal convolutional neural networks for spatial and temporal feature extraction, respectively. The cascade of these extractors, combined with multihead attention mechanisms for both spatio-temporal dimensions, aims to improve predictive precision and refine model explainability. Comprehensive experiments were conducted on the CMAPSS dataset to evaluate the impact of unified versus clustering normalization. The findings suggest that our model performs state-of-the-art results using only the unified normalization. Additionally, when dealing with datasets with multiple operating conditions, cluster normalization enhances the performance of our proposed model by up to 27%.
Smarter Crowdwork by Applying Smart Contracts? European Conference on Information Systems. Hupe, Anna; Bretschneider, Ulrich. In European Conference on Information Systems (ECIS). Kristiansand, Norway, 2023.

Crowdworking is characterized by flexibly engaging a workforce that is recruited for only one task. After the task is completed, the crowdworker and the company do not collaborate anymore. To identify the best-suited crowdwoker for a certain task, crowd working platform providers offer different tools to match both parties. Matching a crowdworker with the required skills for a task is an important factor to complete a crowdworking campaign successfully. As of today, the principal agent theorem and high transaction costs decrease the effectiveness of such campaigns due to information asymmetries between crodworkers and crowdsourcers. Based on a qualitative approach, we structurally develop a currently existing crowdworking campaign process. We then theoretically analyze how smart contracts can support and simplify the identified process while reducing the challenges of transaction cost economics and the principal agent theorem.

Crowdworking is increasingly being applied by companies to outsource tasks beyond their core competencies flexibly and cost-effectively to an unknown group. However, the anonymous and financially incentivized nature of crowdworkers creates information asymmetries and conflicts of interest, leading to inefficiencies and intensifying the principal-agent problem. Our paper offers a solution to the widespread problem of inefficient Crowdworking campaigns. We first derive the currently applied Crowdworking campaign process based on a qualitative study. Subsequently, we identify the broadest adverse selection and moral hazard problems in the process. We then analyze how the blockchain application of smart contracts can counteract those challenges and develop a process model that maps a Crowdworking campaign using smart contracts. We explain how our developed process significantly reduces adverse selection and moral hazard at each stage. Thus, our research provides approaches to make online labor more attractive and transparent for companies and online workers.

Despite its undisputable benefits for firms, crowdsourcing and ‐working is currently rarely applied in small and medium sized enterprises (SME). Up to now extant literature provides only an incomplete picture of the barriers that hinder SMEs from adopting crowdsourcing and ‐working. Because of these incomplete insights on this phenomenon there is also a great deal of uncertainty on how to overcome these barriers. In the scope of an interview series with 15 SMEs we explore a range of different barriers. In a second round of interviews with crowdsourcing and ‐working experts (Delphi study) we reveal strategies that may help SMEs to overcome these barriers. The findings from these two studies not only expand the so far incomplete body of knowledge but also provide practical references for SMEs to overcome the barriers and to adopt crowdsourcing and ‐working for their value creation activities.

Despite considerable research on pool-based deep active learning (DAL), deploying DAL into real applications still has several challenges. A frequently neglected aspect is the choice of training hyperparameters (HPs), such as the learning rate. Since these HPs determine how the deep neural network learns in each cycle, they must be chosen carefully. In this article, we analyze the role of HPs in DAL. We find that optimizing HPs reduces the performance gap between DAL strategies. Conversely, we highlight challenges in finding optimal HPs when using datasets selected via DAL strategies.

Financial fraud has a severe impact on the general population. While financial institutions have technological capabilities for fraud detection using intelligent AI systems, the delay until they have collected a sufficient size of fraudulent data to train their fraud detection models creates a costly vulnerability. One major challenge for quickly training data lies in the inability to share fraud detection training data with other financial institutions, due to data and privacy regulations. Thus, we create the concept for a data-sharing ecosystem platform that addresses data anonymity concerns by creating synthesized training data based on each institution’s fraud detection training data sets. We rely on the advantages of generative adversarial networks (GAN) to quickly construct a shared dataset for all ecosystem members. Applying design science research, this paper derives design knowledge based on financial fraud detection literature, data sharing between financial institutions, GANs and modular systems theory for the design of a plat-form architecture for data-sharing ecosystems.

Uncertainty becomes the new normal for organizations worldwide. Many organizations are dependent on complex global supply chains. COVID-19, but also environmental disasters or the war in Ukraine, demonstrate the volatility of supply chains. Procurement departments are the central interface between internal and external stakeholders and must manage the supply chain stability what requires fast and accurate decision-making. External shocks and sudden disruptions of central supply chains illustrated that data analytics could not prevent disruptions, although sound research on competitive advantages and numerous investments should have enabled organizations to data-driven decision-making. Rather, it became transparent, that there are numerous data deficits in organizations. We did an interview-based study with 23 procurement and supply chain experts about relevant data sets and the status of its usability. We contribute to theory and practice by uncovering relevant aspects of data and provide theoretical propositions on how decision-making can be improved in automotive procurement departments.
Explaining the ghosts: Feminist intersectional XAI and cartography as methods to account for invisible labour. Klumbytė, Goda; Piehl, Hannah; Draude, Claude. 2023.

Contemporary automation through AI entails a substantial amount of behind-the-scenes human labour, which is often both invisibilised and underpaid. Since invisible labour, including labelling and maintenance work, is an integral part of contemporary AI systems, it remains important to sensitise users to its role. We suggest that this could be done through explainable AI (XAI) design, particularly feminist intersectional XAI. We propose the method of cartography, which stems from feminist intersectional research, to draw out a systemic perspective of AI and include dimensions of AI that pertain to invisible labour.

This paper follows calls for critical approaches to computing and conceptualisations of intersectional, feminist, decolonial HCI and AI design and asks what a feminist intersectional perspective in HCXAI research and design might look like. Sketching out initial research directions and implications for explainable AI design, it suggests that explainability from a feminist perspective would include the fostering of response-ability - the capacity to critically evaluate and respond to AI systems - and would centre marginalised perspectives.

Im Alltag werden Smartphones häufig unterwegs eingesetzt, zum Beispiel zur Orientierung oder Informationsbeschaffung. Ihre Verwendung erfordert die Aufmerksamkeit des Nutzers, und oft leidet die Aufmerksamkeit für die Umgebung darunter. Ziel dieser Arbeit war es, Gestaltungslösungen zur Aufmerksamkeitsschonung in der Unterwegsnutzung (mobile Interaktion) zu entwickeln. Für drei typische Komponenten mobiler Applikationen des freizeitbezogenen Anwendungsfeldes wurde je ein Lösungsansatz abgeleitet, der auf einer Anpassung der Komponente an den Kontext (Kontextadaptivität) basiert. Es wurden exemplarische Gestaltungslösungen erarbeitet und in Nutzerstudien auf die Gestaltungsziele Gebrauchstauglichkeit, Aufmerksamkeitsschonung und Nutzerakzeptanz untersucht. Ein Lösungsansatz sieht vor, dem Nutzer die Spracheingabe, statt der Tastatureingabe anzubieten, wenn das Smartphone im Gehen verwendet wird. In einer Studie zeigte sich, dass die Spracheingabe eine effektive und ca. dreifach effizientere Eingabe ermöglicht und das Gehen weniger beeinträchtigt. Trotz geringer Vorerfahrungen wurde die Spracheingabe auch subjektiv nützlicher bewertet. Allerdings scheint die Akzeptanz ihrer Nutzung in öffentlichen Räumen eingeschränkt zu sein. Der zweite Lösungsansatz hat das Ziel, die Verwendung mobiler Karten zu beschleunigen, indem auf den Kartenpins Merkmalsinformationen abgebildet werden, die für den Nutzer aktuell relevant sind. Ein iteratives Vorgehen resultierte in verständlichen Gestaltungslösungen, die ein effektives Auffinden eines gesuchten Kartenpins ermöglichen und die Suchzeit ungefähr halbieren. Als besonders effizient erwiesen sich Gestaltungsvarianten mit farbiger Symbolerweiterung, die zudem am meisten präferiert wurden. Die Ergebnisse deuten auf eine Nutzerakzeptanz für den Lösungsansatz hin. Der dritte Lösungsansatz betrifft Benachrichtigungen, die Informationen zur Reisebegleitung liefern, aber den Nutzer bei einer anderen Aufgabe unterbrechen. Die Benachrichtigungen werden statt auf dem Smartphone auf einer Smartwatch angezeigt, um die Unterbrechung zu verkürzen. In Studien wurde deutlich, dass der Vorteil der Smartwatch in ihrer spezifischen Handhabung liegt, aber das Endgerät selbst keinen Effekt hat. Auch gelang es, eine gebrauchstaugliche benachrichtigungsbasierte Reisebegleitung für Smartwatches zu entwickeln, die von Nutzern akzeptiert wird. Insgesamt konnte in dieser Arbeit gezeigt werden, dass durch die gebrauchstaugliche Gestaltung kontextadaptiver App-Komponenten die Aufmerksamkeit in der mobilen Interaktion geschont werden kann.

Graph Pooling Provably Improves Expressivity. Lachi, Veronica; Moallemy-Oureh, Alice; Roth, Andreas; Welke, Pascal. In Workshop on New Frontiers in Graph Learning, NeurIPS, pp. 1–7. 2023.

In the domain of graph neural networks (GNNs), pooling operators are fundamental to reduce the size of the graph by simplifying graph structures and vertex features. Recent advances have shown that well-designed pooling operators, coupled with message-passing layers, can endow hierarchical GNNs with an expressive power regarding the graph isomorphism test that is equal to the Weisfeiler-Leman test. However, the ability of hierarchical GNNs to increase expressive power by utilizing graph coarsening was not yet explored. This results in uncertainties about the benefits of pooling operators and a lack of sufficient properties to guide their design. In this work, we identify conditions for pooling operators to generate WL-distinguishable coarsened graphs from originally WL-indistinguishable but non-isomorphic graphs. Our conditions are versatile and can be tailored to specific tasks and data characteristics, offering a promising avenue for further research.

This paper describes a concept to adapt the design of quality management in SMEs to better exploit the potential of crowdworking. It shows how the quality management, especially of SMEs, can be organised to make efficient and targeted use of work perfomed by crowd-based mechanisms and continue to ensure that customer requirements are met. The different forms of crowd-based mechanisms will be discussed. Barriers of SMEs in adopting crowdsourcing and strategies to overcome them will be identified. A modular reference process model for the quality-oriented use of crowdworking in SMEs will be developed. In addition, concrete recommendations for action to adapt or supplement the design of quality management in SMEs for the efficient and effective use of crowd-based mechanisms will be given.

The operation of electricity grids has become increasingly complex due to the current upheaval and the increase in renewable energy production. As a consequence, active grid management is reaching its limits with conventional approaches. In the context of the Learning to Run a Power Network (L2RPN) challenge, it has been shown that Reinforcement Learning (RL) is an efficient and reliable approach with considerable potential for automatic grid operation. In this article, we analyse the submitted agent from Binbinchen and provide novel strategies to improve the agent, both for the RL and the rule-based approach. The main improvement is a N-1 strategy, where we consider topology actions that keep the grid stable, even if one line is disconnected. More, we also propose a topology reversion to the original grid, which proved to be beneficial. The improvements are tested against reference approaches on the challenge test sets and are able to increase the performance of the rule-based agent by 27%. In direct comparison between rule-based and RL agent we find similar performance. However, the RL agent has a clear computational advantage. We also analyse the behaviour in an exemplary case in more detail to provide additional insights. Here, we observe that through the N-1 strategy, the actions of both the rule-based and the RL agent become more diversified.

The adoption of innovative technologies confronts IT-Service-Management (ITSM) with an increasing volume and variety of requests. Artificial intelligence (AI) possesses the potential to augment customer service employees. However, the training data for AI systems are annotated by domain experts with little interest in labeling correctly due to their limited perceived value. Ultimately, insufficient labeled data leads to diminishing returns in AI performance. Following a design science research approach, we provide a novel human-in-the-loop (HIL) design for ITSM support ticket recommendations by incorporating a value co-creation perspective. The design incentivizes ITSM agents to provide labels during their everyday ticket-handling procedures. We develop a functional prototype based on 17,120 support tickets provided by a pilot partner as an instantiation and evaluate the design through accuracy metrics and user evaluations. Our evaluation revealed that recommendations after label improvement showed increased user ratings, and users are willing to contribute their domain knowledge. The improved labels can be utilized to continuously enhance the AI system as rewards showed increasing growth with decreasing marginal returns. Overall, our results emphasize agents' need for value-in-use by providing better results if they improve the labeling of support tickets pre-labeled by AI. Thus, we provide prescriptive knowledge of a novel HIL design that enables efficient and interactive labeling in the context of diverse applications of reinforcement learning systems.

Utilizing Continuous Kernels for Processing Irregularly and Inconsistently Sampled Data With Position-Dependent Features. Magnussen, Birk Martin; Stern, Claudius; Sick, Bernhard. In International Conference on Autonomic and Autonomous Systems (ICAS), pp. 49–53. ThinkMind, 2023.

Continuous Kernels have been a recent development in convolutional neural networks. Such kernels are used to process data sampled at different resolutions as well as irregularly and inconsistently sampled data. Convolutional neural networks have the property of translational invariance (e.g., features are detected regardless of their position in the measurement domain), which is unsuitable for certain types of data, where the position of detected features is relevant. However, the capabilities of continuous kernels to process irregularly sampled data are still desired. This article introduces a novel method utilizing continuous kernels for detecting global features at absolute positions in the data domain. Through a use case in processing multiple spatially resolved reflection spectroscopy data, which is sampled irregularly and inconsistently, we show that the proposed method is capable of processing such data natively without additional preprocessing as is needed using comparable methods. In addition, we show that the proposed method is able to achieve a higher prediction accuracy than a comparable network on a dataset with position-dependent features. Furthermore, a higher robustness to missing data compared to a benchmark network using data interpolation is observed, which allows the network to adapt to sensors with individual failed components without the need for retraining.

X‑ray diffraction crystallography allows non‑destructive examination of crystal structures. Furthermore, it has low requirements regarding surface preparation, especially compared to electron backscatter diffraction. However, up to now, X‑ray diffraction has been highly time‑ consuming in standard laboratory conditions since intensities on multiple lattice planes have to be recorded by rotating and tilting. Furthermore, examining oligocrystalline materials is challenging due to the limited number of diffraction spots. Moreover, commonly used evaluation methods for crystallographic orientation analysis need multiple lattice planes for a reliable pole figure reconstruction. In this article, we propose a deep‑learning‑based method for oligocrystalline specimens, i.e., specimens with up to three grains of arbitrary crystal orientations. Our approach allows faster experimentation due to accurate reconstructions of pole figure regions, which we did not probe experimentally. In contrast to other methods, the pole figure is reconstructed based on only a single incomplete pole figure. To speed up the development of our proposed method and for usage in other machine learning algorithms, we introduce a GPU‑based simulation for data generation. Furthermore, we present a pole widths standardization technique using a custom deep learning architecture that makes algorithms more robust against influences from the experiment setup and material.
Marked Neural Spatio-Temporal Point Process Involving a Dynamic Graph Neural Network. Moallemy-Oureh, Alice; Beddar-Wiesing, Silvia; Nather, Rüdiger; Thomas, Josephine. In Workshop on Temporal Graph Learning (TGL), NeurIPS, pp. 1–7. 2023.

Spatio-Temporal Point Processes (STPPs) have recently become increasingly interesting for learning dynamic graph data since many scientific fields, ranging from mathematics, biology, social sciences, and physics to computer science, are naturally related and dynamic. While training Recurrent Neural Networks and solving PDEs for representing temporal data is expensive, TPPs were a good alternative. The drawback is that constructing an appropriate TPP for modeling temporal data requires the assumption of a particular temporal behavior of the data. To overcome this problem, Neural TPPs have been developed that enable learning of the parameters of the TPP. However, the research is relatively young for modeling dynamic graphs, and only a few TPPs have been proposed to handle edge-dynamic graphs. To allow for learning on a fully dynamic graph, we propose the first Marked Neural Spatio-Temporal Point Process (MNSTPP) that leverages a Dynamic Graph Neural Network to learn Spatio-TPPs to model and predict any event in a graph stream. In addition, our model can be updated efficiently by considering single events for local retraining.

Anomaly detection plays a pivotal role in diverse realworld applications such as cybersecurity, fault detection, network monitoring, predictive maintenance, and highly automated driving. However, obtaining labeled anomalous data can be a formidable challenge, especially when anomalies exhibit temporal evolution. This paper introduces LATAM (Long short-term memory Autoencoder with Temporal Attention Mechanism) for few-shot anomaly detection, with the aim of enhancing detection performance in scenarios with limited labeled anomaly data. LATAM effectively captures temporal dependencies and emphasizes significant patterns in multivariate time series data. In our investigation, we comprehensively evaluate LATAM against other anomaly detection models, particularly assessing its capability in few-shot learning scenarios where we have minimal examples from the normal class and none from the anomalous class in the training data. Our experimental results, derived from real-world photovoltaic inverter data, highlight LATAM’s superiority, showcasing a substantial 27% mean F1 score improvement, even when trained on a mere two-week dataset. Furthermore, LATAM demonstrates remarkable results on the open-source SWaT dataset, achieving a 12% boost in accuracy with only two days of training data. Moreover, we introduce a simple yet effective dynamic thresholding mechanism, further enhancing the anomaly detection capabilities of LATAM. This underscores LATAM’s efficacy in addressing the challenges posed by limited labeled anomalies in practical scenarios and it proves valuable for downstream tasks involving temporal representation and time series prediction, extending its utility beyond anomaly detection applications.

Pandemics like COVID-19 highlight the needs and pitfalls of inclusive and equitable education in a digital society. IT-based instructional designs are needed to increase learners’ expertise, and to develop higher-order thinking skills. Instructional designs for collaborative learning (CL) seem to be a promising solution. However, they are mostly suitable for face-to-face and not for distance teaching. The core problem that impedes their reusability and scalability is a ‘collaboration problem’ for which collaboration engineering (CE) provides guidance. Therefore, we deploy a design science research study and contribute to CL and CE literature. We develop requirements and provide the design of an IT-based collaborative work practice fostering CL. We provide empirical evidence with an online experiment in a large-scale lecture with undergraduate business information students. This reveals that groups of learners who followed our CL experience achieve higher levels of expertise than those who followed a traditional ad hoc CL experience.

Collaborative work practices (CWPs) package facilitation expertise and have the potential to increase team productivity up to 90%. Collaboration engineers develop CWPs and deploy them to practitioners that execute them. These CWPs, however, are typically customized to conditions of a specific use case. This creates the challenge that changing use case conditions or even small variations across contexts, hinder well-performing CWPs of being applied more often to create a long-term value. Practitioners fail to adapt existing CWPs due to missing collaboration expertise and adaptation guidelines. To address this challenge in collaboration engineering literature, we introduce a) the Subject Matter Expert role; b) the ‘CWP Adaptation Approach’ that formalizes the transfer of CWPs to different contexts with parameterized Templates and Guidebooks. To show a first proof-of-concept, we further inductively generalize from an exemplarily use case with a well-performing CWP in the educational domain.

Die Sustainable Development Goals (SDGs) der Vereinten Nationen streben anhand von SDG 5 danach, die Gleichheit der Geschlechter im globalen Kontext herzustellen. Wir zeigen, dass der aktuelle, global angelegte Nachhaltigkeitsdiskurs nicht nur blinde Flecken im Hinblick auf die konsequente Bekämpfung geschlechtsspezifischer Ungleichheiten aufweist, sondern auch einen wenig reflektierten Umgang mit der digitalen Transformation pflegt. Mögliche Ansätze zur Bewältigung des identifizierten Spannungsfeldes sehen wir in einer gendersensiblen IT-Gestaltung, einem digitalen Gleichstellungsgesetz und der konsequenten Bewertung von Folgen der globalen Nachhaltigkeitspolitik und -forschung im Hinblick auf Diskriminierung.

Some classes of person-oriented services such as healthcare services require individualization to be effective. Individualizing services and corresponding patient pathways are costly. To provide such services in an individualized, but also efficient manner, service modularization is known as a solution. Until now, modularization parameters that take healthcare specificities into account are missing. This paper closes this gap. Following a design science research approach, we iteratively build and evaluate a set of healthcare-specific modularization parameters. For requirements elicitation, refinement of the modularization parameters and their evaluation, we conduct interviews with domain experts from patient pathways in oncology care as well as with service design and business development experts. As main theoretical contribution, this paper provides design knowledge for the modularization of healthcare services. For practice, the set of parameters assists healthcare providers in the efficient provision of individualized, patient-centric solutions and patient pathways.

Remote sensing through semantic segmentation of satellite images contributes to the understanding and utilisation of the earth's surface. For this purpose, semantic segmentation networks are typically trained on large sets of labelled satellite images. However, obtaining expert labels for these images is costly. Therefore, we propose to rely on a low-cost approach, e.g. crowdsourcing or pretrained networks, to label the images in the first step. Since these initial labels are partially erroneous, we use active learning strategies to cost-efficiently refine the labels in the second step. We evaluate the active learning strategies using satellite images of Bengaluru in India, labelled with land cover and land use labels. Our experimental results suggest that an active label refinement to improve the semantic segmentation network's performance is beneficial.

We propose a shift towards end-to-end learning in bird sound monitoring by combining self-supervised (SSL) and deep active learning (DAL). Leveraging transformer models, we aim to bypass traditional spectrogram conversions, enabling direct raw audio processing. ACTIVE BIRD2VEC is set to generate high-quality bird sound representations through SSL, potentially accelerating the assessment of environmental changes and decision-making processes for wind farms. Additionally, we seek to utilize the wide variety of bird vocalizations through DAL, reducing the reliance on extensively labeled datasets by human experts. We plan to curate a comprehensive set of tasks through Huggingface Datasets, enhancing future comparability and reproducibility of bioacoustic research. A comparative analysis between various transformer models will be conducted to evaluate their proficiency in bird sound recognition tasks. We aim to accelerate the progression of avian bioacoustic research and contribute to more effective conservation strategies.

AI-based recommendation systems to augment working conditions in the field of IT service management (ITSM) have attracted new attention. However, many IT support organizations possess high volumes of tickets but are confronted with low quality, to which they train the underlying models of their AI systems. In particular, support tickets are documented insufficiently due to time pressure and lack of motivation. Following design science research, we design and evaluate an analytics pipeline to address the data quality issue. The pipeline can be applied to assess and extract high-quality support tickets for subsequent model training and operation. Based on a data set of 60.000 real-life support tickets from a manufacturing company, we develop the artifact, instantiate a recommender system and achieve a higher pre-diction performance in comparison to naïve enrichment methods. In terms of data management literature, we contribute to the understanding of as-sessing textual ticket data quality. By deriving a pipeline reference model, we move towards a general approach to designing machine learning-driven data quality analytics pipelines for attached recommender systems.

Due to the high drop-out rates in IT support desks, efficient onboarding of novices becomes a relevant and recurring challenge. Especially in the case of IT support, solving technical issues and service requests while the conversation with the customer is still ongoing imposes high demands on novice support agents. As artificial intelligence (AI) can already classify service requests and help find solutions, AIbased augmentation holds great potential for improving the onboarding phase and reducing time-to-performance. For this reason, we propose an AI-based conversational (co-)agent during the onboarding phase of customer support novices to reduce the time spent on service tasks and enable on-the-job training. Following action design research, we aim to develop an instantiation of an AI-based co-agent to reduce the job demand for the service center agent novices and augment problem-solving capabilities by considering cognitive load. The co-agent will be implemented with one development partner and evaluated with two different case partner organizations. In this research-in-progress project, we developed a low-fidelity prototype and derived a tentative architecture that allows for a generalized development of such conversational agents in customer service organizations.

Social Audio: Conceptualizing Voice-Based Online Social Networks and their Privacy Implications. Schmitt, Anuschka; Rentsch, Stefanie; Janson, Andreas. In Annual Meeting of the Academy of Management (AOM). Boston, Massachusetts, USA, 2023.
- [ Abstract ]
- [ BibSonomy-Post ]
This paper explores the nature and implications of social audio: online social networks (OSNs) that enable users to interact via voice. The paper contributes to basic science by offering a precise conceptualization of voice-based OSNs and their design features. We posit that the defining characteristics of traditional OSNs also hold for social audio, yet that novel features (i.e., creating rooms) and modifications of traditional features (i.e., like) through voice idiosyncrasies can be found. This work also shows how social audio introduces novel privacy implications, particularly driven by the richness and risks of voice as an interaction modality. Using three illustrative cases, we demonstrate applications of social audio and how privacy implications remain largely unaddressed. Specifically, we find that the networks considered show very few specific features addressing the risks of voice-based interaction and that current privacy policies do not reflect these risks nor offer mitigation measures. We bridge our findings and extensions for future research by discussing potential approaches in terms of network architecture features for social audio providers to pursue in order to ensure user privacy.

Organizations claim to host what is called a metaverse – an extended version of our real world. First rudimental realizations of such metaverses can be found throughout the internet, e.g., Epic Game’s Fortnite. At the same time, research and practice struggle to specify what a metaverse truly is and how we can characterize it. With our work, we analyze the proximity of the realization of a holistic metaverse platform and present the results of a qualitative interview study (n=30). The goal of our work is to use the expertise of practitioners to discuss different examples that claim to represent a metaverse, e.g., Second Life and Decentraland. To achieve this goal, we develop a typology we call the Metagon and use it to evaluate existing metaverse platforms. We contribute to theory by clarifying the meaning of metaverse platforms. Practitioners are guided by a demonstration of metaverse characteristics.

Metaverse is the buzzword of modern society. Practitioners and researchers have discussed metaverse platforms extensively, but the potential and meaning of the metaverse remain controversial. In this paper, we investigate and identify challenges that enable the potential of metaverse platforms. If these challenges are overcome, there will be value creation for practitioners, organizations, and society. We used a qualitative approach whereby we interviewed 34 metaverse experts to identify the challenges, potential, and value associated with the metaverse. Our results demonstrate that technical and societal challenges obstruct the ability to handle user-related and organizational challenges. If these challenges can be overcome, we can use the opportunities that our participants identified to create functional, social, and emotional value. Our work theoretically contributes to current knowledge on metaverse platforms by elaborating on handling metaverse platform ecosystems and determining instrumental challenges in their realization. With our qualitative approach, we provide room and directions for future research to develop a better understanding of the role and meaning of value creation in the metaverse. Our findings are useful to practitioners by presenting challenges organizations must overcome to create metaverse platforms or participate in a metaverse ecosystem. Furthermore, we present opportunities for vendors of metaverse platforms and organizations by identifying relevant processes that can be transferred into the metaverse.

This article discusses the role that algorithmic thinking and management play in health care and the kind of exclusions this might create. We argue that evidence-based medicine relies on research and data to create pathways for patient journeys. Coupled with data-based algorithmic prediction tools in health care, they establish what could be called health care algorithmics—a mode of management of healthcare that produces forms of algorithmic governmentality. Relying on a critical posthumanist perspective, we show how healthcare algorithmics is contingent on the way authority over bodies is produced and how predictive health care algorithms can reproduce inequalities of the worlds from which they are made, centreing possible futures on existing normativities regulated through algorithmic biopower. In contrast to that, we explore posthuman speculative ethics as a way to challenge understanding of ‘ethics’ and ‘care’ in healthcare algorithmics. We suggest some possible avenues towards working speculative ethics into health care while still being critically attentive to algorithmic modes of management and prediction in health care.

Continuing vocational training benefits from the employees’ ability to share individual experience and expertise with their co-workers, as these assets constitute competitive advantages for companies. IT-supported systems can facilitate processes of knowledge elicitation (e. g. as part of collaborative co-creation) to ensure retainment of preferred qualitative characteristics of the resulting knowledge artifacts and provide ample opportunities to manage and configure a growing number of such artifacts in a company’s repository. It remains unclear however, how such collaborative and digital co-creation processes can benefit the individual co-creators’ expertise development. To address this gap in research and practice, an IT-supported co-creation system for microlearnings is designed and evaluated with master craftsman trainees of an inter-company vocational training center. With the deployment of the co-creation system, knowledge elaboration was examined via a qualitative evaluation of concept maps. By applying categories of the maps’ semantic properties and comparing features of expert knowledge derived from expertise research and concept mapping literature, we evaluate the process’ function to support expert knowledge elaboration as a desirable learning outcome for co-creators of shared digital artifacts. Analysis of the concept maps shows an absence of theoretical reasoning and an emphasis on contextual factors with minute details of work processes, indicating more practical than expert knowledge formation when co-creating shared digital artifacts. To improve the IT system’s effective support for expert knowledge elicitation, adjustments to the structured procedure are discussed and future research directions and limitations of this study are addressed.

Graphs are ubiquitous in nature and can therefore serve as models for many practical but also theoretical problems. For this purpose, they can be defined as many different types which suitably reflect the individual contexts of the represented problem. To address cutting-edge problems based on graph data, the research field of Graph Neural Networks (GNNs) has emerged. Despite the field’s youth and the speed at which new models are developed, many recent surveys have been published to keep track of them. Nevertheless, it has not yet been gathered which GNN can process what kind of graph types. In this survey, we give a detailed overview of already existing GNNs and, unlike previous surveys, categorize them according to their ability to handle different graph types and properties. We consider GNNs operating on static and dynamic graphs of different structural constitutions, with or without node or edge attributes. Moreover, we distinguish between GNN models for discrete-time or continuous-time dynamic graphs and group the models according to their architecture. We find that there are still graph types that are not or only rarely covered by existing GNN models. We point out where models are missing and give potential reasons for their absence.

Human-agent interaction is increasingly influencing our personal and work lives through the proliferation of conversational agents in various domains. As such, these agents combine intuitive natural language interactions by also delivering personalization through artificial intelligence capabilities. However, research on CAs as well as practical failures indicate that CA interaction oftentimes fails miserably. To reduce these failures, this paper introduces the concept of building common ground for more successful human-agent interactions. Based on a systematic review our analysis reveals five mechanisms for achieving common ground: (1) Embodiment, (2) Social Features, (3) Joint Action, (4) Knowledge Base, and (5) Mental Model of Conversational Agents. On this basis, we offer insights into grounding mechanisms and highlight the potentials when considering common ground in different human-agent interaction processes. Consequently, we secure further understanding and deeper insights of possible mechanisms of common ground in human-agent interaction in the future.

As educational organizations face difficulties in providing personalized learning material or individual learning support, pedagogical conversational agents (PCAs) promise individualized learning for students. However, the problem of conversational breakdowns of PCAs and consequently poor learning outcomes still exist. Hence, effective and grounded communication between learners and PCAs is fundamental to improving learning processes and out-comes. As understanding each other and the conversational grounding is crucial for conversations between humans and PCAs, we propose common ground theory as a foundation for designing a PCA. Conducting a design science research project, we propose theory-motivated design principles and instantiate them in a PCA. We evaluate the utility of the artifact with an experimental study in higher education to inform the subsequent design iterations. We contribute design knowledge on conversational agents in learning settings, enabling researchers and practitioners to develop PCAs based on common ground research in education and providing avenues for future research. Thereby, we can secure further understanding of learning processes based on grounding communication.

Heterogeneous Multi-Source Deep Adaptive Knowledge-Aware Learning for E-Mobility. Ali, Mohammad Wazed. In IEEE International Conference on Autonomic Computing and Self-Organizing Systems Companion (ACSOS-C), pp. 57–60. IEEE, 2022.

Electromobility (e-mobility) reduces global fossil fuel-based energy demand and promotes the usage of renewable energy sources. Different types of electric vehicle (EVs) production have increased recently due to their need. However, there is no fixed charging behavior, and demand exists. Uncontrolled EV charging may lead to a harmful impact on the power grid. Besides, most renewable energy sources depend highly on the weather and location. Thus, analyzing, forecasting, and adapting EV charging demand is essential to prevent power outages. Deep Learning (DL) models are a de facto standard technology for energy forecasting in many scenarios. Still, there is a lack of real-world data in the e-mobility domain to train a DL model from scratch. Besides, DL models have explainability issues, which can hinder decision-making. This article proposes a novel framework for addressing data scarcity issues, enabling continuous adaptation to change, and improving explainability.

Electromobility can reduce global energy demand by reducing the dependence on fossil fuels. Many different types of electric vehicles (EVs) have been produced recently and EV usage is also rising. However, there is no fixed charging behavior of these EV users. Moreover, most renewable energy sources are stochastic in nature. Thus, it is essential that EV charging demand is controlled and adapted in advance to prevent catastrophic failures such as blackouts. Deep learning models are standard technology for power forecasting in many scenarios. However, there is a lack of real-world heterogeneous multi-source data in the e-mobility domain to train a deep learning model from scratch. Moreover, deep learning (DL) models lack model explainability. Therefore, EV stakeholders can benefit from a framework that coordinates deep transfer learning, interactive machine learning, and heterogeneous graph representation learning (to ensure self-explainability). This work aims to develop a novel framework to solve e-mobility-related tasks such as forecasting EV loads efficiently in a resource-constrained environment (data, computing power, etc.). It also describe various research challenges and potential approaches to build the proposed framework. This work also present a deep generative model to synthesize EV charging session data.

In this article Lila Athanasiadou and Goda Klumbytė engage in a conversation with Antoinette Rouvroy to revisit Guattari’s "Three Ecologies" and discuss their dynamics in and for the digital age. While a lot of the discourses on algorithms and digital future invoke catastrophic imaginaries of totalizing control, this conversation works with a propositional format, teasing out affirmative politics by pointing to spaces of potentiality within the environmental, the social and the mental realm. Starting from the environmental ecology and thinking of data as a waste, Rouvroy discusses planetary exhaustion as the result of the depletion of natural resources, forced labour practices and the assumption that data hold the answers to the problems posed by global capital. Proposing a space for material experimentation, she speculates on the potential of emerging subjectivities that remain irreducible to data flows. Within social ecology, Rouvroy advocates for the urgency to center digital policy as the space in which the new forms of institutions emerge in order to reorient the power of computation towards the commons. Lastly, within the mental ecology, Rouvroy reconceptualizes the legal subject as a performance that operates within the proliferation of asignifying data signs, reimagining a “we” beyond the gathering of reductions.

Digitale Arbeitsumgebungen sind heutzutage allgegenwärtig. Zugleich hat die Anzahl an Möglichkeiten, Informationen über Arbeitstätigkeiten sowie sensible persönliche Daten elektronisch zu erfassen, drastisch zugenommen (Backhaus 2019). Unternehmen nutzen immer mehr Formen von digitalen Arbeitssystemen und setzen fortschrittliche Instrumente wie Big Data Analytik oder Künstliche Intelligenz ein. Damit können Daten schneller und in größerem Umfang als je zuvor gesammelt, aggregiert und analysiert werden (Malhotra et al. 2004). Darüber hinaus können Daten gesammelt werden, ohne dass der Einzelne davon weiß (Bélanger and Crossler 2011). Auf der einen Seite birgt die weit verbreitete Analyse von persönlichen Daten ein erhebliches Innovationspotenzial, einen wirtschaftlichen Wert sowie effizientere Arbeitsmodelle (Erevelles et al. 2016). Auf der anderen Seite ist die Anfälligkeit für Diskriminierung, kommerzielle Ausbeutung und unerwünschte Überwachung ebenso allgegenwärtig. Dadurch wird die Akzeptanz moderner IT‐Systeme behindert. Dieser Interessenkonflikt wird sich in den kommenden Jahren vermutlich noch verschärfen, da die Unternehmen von der fortschreitenden Digitalisierung profitieren.

Graph isomorphism (GI) has occupied both theoreticians and applied scientists since the early 1950s. Over the years, several approaches and algorithms with which an isomorphism between two graphs can be tested have been developed. A general approach is the Weisfeiler–Lehman (WL) test, which is based on a coloring algorithm and provides a necessary criterion for graph isomorphism. However, the WL test is restricted to examining graphs with only node attributes. Therefore, this paper presents two extensions of the WL algorithm to allow for testing on arbitrary graphs. One considers edge attributes, and the other tests the isomorphism on dynamic graphs. Additionally, we extend the WL-hierarchy by the attributed and dynamic WL tests and show that it is a partial order, which induces a lattice. In the future, this may allow for practical implications coming from lattice theory.

Graph Neural Networks (GNNs) are a large class of relational models for graph processing. Recent theoretical studies on the expressive power of GNNs have focused on two issues. On the one hand, it has been proven that GNNs are as powerful as the Weisfeiler-Lehman test (1-WL) in their ability to distinguish graphs. Moreover, it has been shown that the equivalence enforced by 1-WL equals unfolding equivalence. On the other hand, GNNs turned out to be universal approximators on graphs modulo the constraints enforced by 1-WL/unfolding equivalence. However, these results only apply to Static Undirected Homogeneous Graphs with node attributes. In contrast, real-life applications often involve a variety of graph properties, such as, e.g., dynamics or node and edge attributes. In this paper, we conduct a theoretical analysis of the expressive power of GNNs for these two graph types that are particularly of interest. Dynamic graphs are widely used in modern applications, and its theoretical analysis requires new approaches. The attributed type acts as a standard form for all graph types since it has been shown that all graph types can be transformed without loss to Static Undirected Homogeneous Graphs with attributes on nodes and edges (SAUHG). The study considers generic GNN models and proposes appropriate 1-WL tests for those domains. Then, the results on the expressive power of GNNs are extended by proving that GNNs have the same capability as the 1-WL test in distinguishing dynamic and attributed graphs, the 1-WL equivalence equals unfolding equivalence and that GNNs are universal approximators modulo 1-WL/unfolding equivalence. Moreover, the proof of the approximation capability holds for SAUHGs, which include most of those used in practical applications, and it is constructive in nature allowing to deduce hints on the architecture of GNNs that can achieve the desired accuracy.

Today’s servitized and digitalized society has significant implications for the economic system as value creation increasingly shifts towards digital services. Organizations are increasingly relying of artificial intelligence, which enables them to operate with novel technological artifacts like conversational agents (CA). These human-like AI-driven artifacts open new possibilities and channels for service providers to scale up their business even further and to create a business value or even to make processes more efficient. While we witness the results of that each day, we do not fully understand how such CAs can contribute to scaling up a business. Therefore, we conduct an analysis of service research and popular CAs to determine the status quo and highlight opportunities for scaling services with CAs. We contribute to theory by clarifying the meaning of scalability in combination with CAs and support practitioners by providing an overview about how organizations successfully scale their CAs.
Towards Gamified Conversational Agents for Self-Regulated Learning in Digital Education. Benner, Dennis; Schöbel, Sofia; Sueess, Christoph. In International Conference on Information Systems (ICIS). Copenhagen, Denmark, 2022.

Formal education like higher education oftentimes emphasized on strict non-digital setting. This approach can lead to issues during stressful times (e.g., Covid crisis) or when learners’ needs in general are not considered. Moreover, these times highlighted how important self-regulated learning is and how much this capability is lacking in our educational system. To address these issues, we follow an Action Design Research approach and develop a gamified conversational agent (CA) that considers the learners’ needs. We present our CA and conduct a first small-scale evaluation following a mixed-method approach. First results show that students universally liked a CA for self-regulated digital learning and many enjoyed the gamified experience which helped students to be motivated to learn. As next steps we will develop the next iteration of our CA and conduct a long-term field test at a university.

Driven by circumstances like the global pandemic many learners and educators realize the importance and value of self-regulated digital learning. To better support self-regulated learning, conversational agents have become more relevant. Conversational agents can act as tutor or as learning mate for learners. Although conversational agents have potential to better support self-regulated learning processes, challenges exist requiring implications about how to make these interactions more engaging and supportive. This study discusses the value of gamified conversational learning chatbots that use game elements to engage learners to guide researchers and practitioners to design conversational agents that effectively motivate learners and provide self-regulated learning at the same time. Therefore, we propose a systematically developed framework for gamifying educational conversational agents and contribute to theory by consolidating several theories about games, digital learning, and conversational agents and support practitioners by providing implications about what to care about when gamifying conversational agents.

- [ Abstract ]
- [ BibSonomy-Post ]
The notion of the posthuman continues to both intrigue and confuse, not least because of the huge number of ideas, theories and figures associated with this term. More Posthuman Glossary provides a way in to the dizzying array of posthuman concepts, providing vivid accounts of emerging terms. It is much more than a series of definitions, however, in that it seeks to imagine and predict what new terms might come into being as this exciting field continues to expand. A follow-up volume to the brilliant interventions of Posthuman Glossary (2018), this book extends and elaborates on that work, particularly focusing on concepts of race, indigeneity and new ideas in radical ecology. It also includes new and emerging voices within the new humanities and multiple modes of communicating ideas. This is an indispensible glossary for those who are exploring what the non-human, inhuman and posthuman might mean in the 21st century.

This work focuses on the prediction of hot deformation behavior of thermo-mechanically processed precipitation hardenable aluminum alloy AA7075. Data available are focusing on a novel hot forming process at different tool temperatures ranging from 24°C to 350°C to set different cooling rates after solution-heat-treatment. Isothermal uniaxial tensile tests in the temperature range from 200°C to 400°C and at strain rates ranging from 0.001 s^-1 to 0.1 s^-1 were carried out on four different material conditions. The present paper mainly focuses on a comparative study of modeling techniques based on Machine Learning (ML) and the well-known Zerilli-Armstrong model (Z-A) as an empirically based reference. Work focused on predicting single data points of curves that the model was trained on. Due to the novel way data were split with respect to training and testing data, it becomes possible to predict entire stress-strain curves which leads to a reduction in the number of required laboratory experiments, finally saving costs and time in future experiments. While all investigated ML methods showed a higher performance than the Z-A model, the extreme Gradient Boosting model (XGB) showed the superior results, i.e., highest error reduction of 91% with respect to the Mean Squared Error.

Design Thinking has become a well-established approach to solving wicked problems through creative and conceptual solutions. Thus, Design Thinking approaches usually end with finding novel solutions but do not offer support in the practical implementation of these solutions. To bridge the gap between finding creative solutions and implementing them into suitable end products, we see Design Patterns as a useful approach to combine the advantages of both sides—the human-centered Design Thinking approach and the practical implementation in system development. Design Patterns offer proven solutions to recurring problems and thus provide design knowledge to solve complex design problems. In this contribution, we demonstrate how Design Patterns act as a complement to Design Thinking by using the example of designing a lawful smart personal learning assistant. We use Design Thinking to extract the design solution of the lawful learning assistant and develop it with the help of Design Patterns. We demonstrate the use of Design Patterns by using the deletion routine Design Pattern as an example of how a Design Pattern can be used for lawful design in addition to their known fields of application in system development. The evaluation results show that the combination of Design Thinking and Design Patterns lead to an approach that not only identifies novel, complex solutions but also supports their practical implementation.

Design science projects are of great interest in information systems (IS) research. Typically, design-oriented projects generate valuable design knowledge through the design and possible instantiation of artifacts. Although designing novel artifacts and accumulating design knowledge is common practice in IS, there is still limited shared knowledge about the distinctive characteristics of design knowledge to facilitate its accumulation. To address this issue, we develop a design knowledge taxonomy and contribute to a deeper understanding of design knowledge properties. The taxonomy is grounded on a systematic literature review, followed by a combination of empirical-to-conceptual and conceptual-to-empirical iterations. We evaluate the taxonomy by interviewing six domain experts and demonstrate its practical application and utility. Thus, the taxonomy consists of key dimensions and characteristics of design knowledge and contributes to a better scientific understanding of its characteristics. Practitioners can use the taxonomy as an instrument to further understand, design, and accumulate design knowledge.

The goal of design science research is the generation of novel artifacts. Thereby DSR projects generate valuable design knowledge, thus, underscoring the importance to codify of design knowledge for achieving scientific progress. The research community observes that DSR projects generate a large amount of design knowledge, but the developed knowledge often ends as a single success story. To counter this situation, we analyze the variety of design knowledge representation forms that have been published in the AIS Senior Scholars’ Basket in design science research papers. Based on our systematic literature review, we identify prevalent ways of design knowledge representations. We provide as a central contribution how to effectively communicate design knowledge through the derivation of recommendations that provides practical guidance to support researchers and practitioners in making design knowledge contributions reusable and applicable.

Durch die Digitalisierung werden immer mehr Technologien entwickelt. Dabei gewinnt die soziotechnische Systementwicklung zunehmend an Bedeutung, in deren Rahmen nicht nur das technische System isoliert betrachtet wird, sondern auch der Nutzer und sein Umfeld. Insbesondere bei der Entwicklung rechtsverträglicher Systeme stehen Entwickler häufig aufgrund fehlenden rechtlichen Fachwissens vor großen Herausforderungen. Dies gilt insbesondere dann, wenn es um intelligente, selbstlernende Systeme geht. Diese Systeme sammeln, um die Qualität ihrer Dienste zu optimieren und Nutzerbedürfnissen zu entsprechen mithilfe leistungsfähiger Technologien große Mengen an personenbezogenen Daten, was Risiken für die informationelle Selbstbestimmung der Nutzer mit sich bringt. Um diesen Risiken entgegenzuwirken nutzen wir Anforderungs- und Entwurfsmuster. Ziel des Beitrags ist daher mittels eines multi-methodischen Ansatzes aufzuzeigen, welchen Beitrag interdisziplinäre Anforderungs- und Entwurfsmuster für die Entwicklung rechtsverträglicher und qualitativ hochwertiger KI-basierter Systeme leisten können. Um die Wirksamkeit der Muster zu untersuchen wurde mithilfe der Muster ein Lernassistent entwickelt und durch die Methode der Simulationsstudie evaluiert.

In order to individualize and personalize digital services, an increasing number of e-commerce providers are exploiting abundant amounts of customer information. Alongside these positive effects, an inherent risk of compromise of customer information arises, resulting in data breaches. Compelled by regulations, companies are obliged to notify their customers. Previous literature indicates that different data breach response strategies can mitigate the negative effects of these security incidents. Drawing on data breach and conversational agent (CA) research, we theorize that the manner in which a data breach is communicated is equally relevant. We test our developed hypotheses in an online experiment (n=89). Our results show that explaining a data breach increases customer satisfaction. Simultaneously, we reveal that CAs lend themselves as a tool to positively influence this degree of explanation. Our work provides novel insights into the centrality of explanation in a data breach response and their positive correlation with CAs.

On behalf of the German Federal Ministry of Economic Affairs and Climate Action, DIN and DKE started work on the second edition of the German Standardization Roadmap Artificial Intelligence in January 2022. With the broad participation and involvement of more than 570 experts from industry, science, the public sector and civil society, the strategic Roadmap for AI standardization was thus further developed. This work was coordinated and accompanied by a high-level coordination group for AI standardization and conformity The standardization roadmap implements a measure of the German government’s AI Strategy and thus makes a significant contribution to “AI – Made in Germany”. Standardization is part of the AI Strategy and is a strategic instrument for strengthening the innovation and competitiveness of the German and European economies. Not least for this reason, standardization plays a special role in the planned European legal framework for AI, the Artificial Intelligence Act. This Standardization Roadmap AI identifies the requirements in standardization, formulates concrete recommendations and thus creates the basis for initiating standardization work at national level, and especially at European and international level, at an early stage. In doing so, the Roadmap makes a significant contribution to the European Commission’s Artificial Intelligence Act, supporting its implementation. The Standardization Roadmap AI focuses on nine key topics, which are addressed in Chapter 4: → The Roadmap begins with the basic topics, such as terminologies and definitions, classifications and ethical issues. They are the basis for AI discussions and are thus the central core of the Roadmap. → The security/safety of AI systems plays a crucial role in widespread use of AI solutions. Only a more in-depth consideration of requirements for operational safety and information security, for example, can enable the comprehensive use of AI systems in business and society. → Another key topic, and the basis for the broad market success of AI, is testing and certification. This requires reliable quality criteria and reproducible test methods that can be used to verify the properties of AI systems. They are a key prerequisite for assessing the quality of AI-based applications and contribute significantly to explainability and traceability – two factors that build trust and acceptance. → Another challenge in the use of AI, especially for small and medium-sized enterprises, is the integration of AI technologies in organizations. The focus here is on sociotechnical aspects such as human-technology interaction, humane work design, and requirements for business structures and processes, which are all examined in the Roadmap. → The fields of application of AI are extremely diverse. AI technologies are used in almost all business and application areas and offer great potential. To cover a broad spectrum of applications, the Roadmap considers industry-specific challenges for the following five sectors in particular, in addition to the cross-cutting issues mentioned above: Industrial Automation, Mobility, Medicine, Financial Services and Energy / Environment. The present Roadmap outlines the work and discussion results for all nine key topics and provides a comprehensive overview of the status quo, requirements, and needs for action.

Experiments are the elective tool for developing new technologies, testing hypotheses, and designing new materials in many scientific fields. Thereby, it is state-of-the-art to create experiments traditionally, starting with a hypothesis leading to the product or relevant data after several experiment cycles. There are some techniques such as automation, parallelization, or inverse design to accelerate experiments. Particularly interesting, however, is the approach to integrate immediate data analysis into the experiment cycle. By analyzing experiment output data on-site using, e.g., neural networks, one can make inferences regarding the experiment's current settings at run-time and furthermore improve them. In the following research project, the goal is to develop and incorporate a data analysis stage into an experimental setup, which can be actively adapted and designed on-site. To demonstrate the developed method, the experimental design of a self-amplification of spontaneous emission pulse characterization experiment at a free-electron laser will be used to show to what extent the experiment can be adapted and optimized.

Social Machines sind ein Paradigma für die Gestaltung soziotechnischer Systeme, die unter Verwendung von Web- und Plattformlösungen das Potenzial digitaler Technologien mit der Eigenlogik sozialer Interaktion, Organisation und Struk- turbildung auf neue Weise zusammenführen. Im Folgenden diskutieren wir das Paradigma der Social Machine aus den Perspektiven der Informatik, der Wirtschaftsinformatik, der Soziologie und des Rechts, um Orientierungspunkte für seine Gestaltung zu identifizieren. Der Begriff ist in der Literatur jedoch bisher nicht abschließend definiert sondern nur durch Beispiele illustriert. In diesem Artikel stellen wir zunächst die folgende Definition zur Diskussion: Social Machines sind soziotechnische Sys- teme, in denen die Prozesse sozialer Interaktion hybrid zwischen menschlichen und maschinellen Akteuren ablaufen und teilweise algorithmisiert sind. Im Anschluss beleuchten wir drei aktuelle, sich gegenseitig bedingende Entwicklungen von Social Machines: die immer stärkere Verschmelzung von Sozialität und Maschine, die Vermessung von Nutzeraktivitäten als Grundstoff gesellschaftlichen Zusammenhalts und die zunehmende Algorithmisierung gesellschaftlicher Prozesse. Ab- schließend diskutieren wir, dass eine teilhabeorientierte, demokratischen Werten folgende Gestaltung von Social Machines die Perspektiven der Nutzungsakzeptanz, der gesellschaftlichen Akzeptabilität und der nachhaltigen Wirtschaftlichkeit adressieren und umsetzen muss.

Discovering Locally Maximal Bipartite Subgraphs. Dürrschnabel, Dominik; Hanika, Tom; Stumme, Gerd. 2022.

Induced bipartite subgraphs of maximal vertex cardinality are an essential concept for the analysis of graphs. Yet, discovering them in large graphs is known to be computationally hard. Therefore, we consider in this work a weaker notion of this problem, where we discard the maximality constraint in favor of inclusion maximality. Thus, we aim to discover locally maximal bipartite subgraphs. For this, we present three heuristic approaches to extract such subgraphs and compare their results to the solutions of the global problem. For the latter, we employ the algorithmic strength of fast SAT-solvers. Our three proposed heuristics are based on a greedy strategy, a simulated annealing approach, and a genetic algorithm, respectively. We evaluate all four algorithms with respect to their time requirement and the vertex cardinality of the discovered bipartite subgraphs on several benchmark datasets

Volatility, uncertainty, complexity, and ambiguity (VUCA) are drivers in today's business world. To perform amid this accelerated change and the digitalization progress, organizations are implementing agility. However, such an implementation does not happen without stumbling blocks and some fail. One reason for this is actors’ agile mindset (AM), which is necessary to deal succefully within a VUCA environment. Knowledge of the AM is in its infancy and conceptualization and measuring tools for it are lacking. Furthermore, the relation of the AM in terms of strategic agility and performance is still unclear. Our study aims to close these gaps. We examine AM through 15 interviews and a survey (N = 449) to predict strategic agility and performance. As a result, we conceptualize AM as an attitude that comprises four dimensions: attitude towards 1) learning spirit, 2) collaborative exchange, 3) empowered self-guidance, and 4) customer co-creation. Furthermore, we describe how actors with an AM deal with new technologies. We found that AM affects organizational performance mediated by strategic agility. These findings contribute to the agility and management research by providing a conceptualization and measuring instrument for AM. Furthermore, its relevance for strategic agility is explained and its relationship with organizational performance outlined.

Innovation requires organizations to tap into the knowledge and creativity of teams. However, teams are confronted with massive amounts of data and information, necessitating a broad set of knowledge, methodologies, and approaches to solve problems and innovate. Consequently, team composition has become a critical challenge. Recent advances in artificial intelligence (AI) may assist in addressing this challenge. As AI is permeating both business and private sectors, organizational teams may be augmented with AI team members. However, given the nascent nature of this phenomenon, little is known about the specific roles and requirements for such AI teammates. Within an interview study we discover common challenges in teams and identify recurring capability gaps of participants and behaviors that negatively impact the team's collective performance. Based on our findings, we propose requirements for AI-based teammates to address these gaps and support beneficial collaboration between humans and AI in teams.

Intelligent agents (IAs) are permeating both business and society. However, interacting with IAs poses challenges moving beyond technological limitations towards the human-computer interface. Thus, the knowledgebase related to interaction with IAs has grown exponentially but remains segregated and impedes the advancement of the field. Therefore, we conduct a systematic literature review to integrate empirical knowledge on user interaction with IAs. This is the first paper to examine 107 Information Systems and Human-Computer Interaction papers and identified 389 relationships between design elements and user acceptance of IAs. Along the independent and dependent variables of these relationships, we span a research space model encompassing empirical research on designing for IA user acceptance. Further we contribute to theory, by presenting a research agenda along the dimensions of the research space, which shall be useful to both researchers and practitioners. This complements the past and present knowledge on designing for IA user acceptance with potential pathways into the future of IAs.

Facilitated by AI technology, the phenomenon of cognitive automation extends the scope of deterministic business process automation (BPA) through the probabilistic automation of knowledge and service work. By transforming work systems through cognitive automation, organizations are provided with vast strategic opportunities to gain business value. However, research lacks a unified conceptual lens on cognitive automation, which hinders scientific progress. Thus, based on a Systematic Literature Review, we describe the fundamentals of cognitive automation and provide an integrated conceptualization. We provide an overview of the major BPA approaches such as workflow management, robotic process automation, and Machine Learning-facilitated BPA while emphasizing their complementary relationships. Furthermore, we show how the phenomenon of cognitive automation can be instantiated by Machine Learning-facilitated BPA systems that operate along the spectrum of lightweight and heavyweight IT implementations in larger IS ecosystems. Based on this, we describe the relevance and opportunities of cognitive automation in Information Systems research.
Efficient SVDD sampling with approximation guarantees for the decision boundary. Englhardt, Adrian; Trittenbach, Holger; Kottke, Daniel; Sick, Bernhard; Böhm, Klemens. In Machine Learning, 111(4), pp. 1349–1375. Springer, 2022.

Support Vector Data Description (SVDD) is a popular one-class classifier for anomaly and novelty detection. But despite its effectiveness, SVDD does not scale well with data size. To avoid prohibitive training times, sampling methods select small subsets of the training data on which SVDD trains a decision boundary hopefully equivalent to the one obtained on the full data set. According to the literature, a good sample should therefore contain so-called boundary observations that SVDD would select as support vectors on the full data set. However, non-boundary observations also are essential to not fragment contiguous inlier regions and avoid poor classification accuracy. Other aspects, such as selecting a sufficiently representative sample, are important as well. But existing sampling methods largely overlook them, resulting in poor classification accuracy. In this article, we study how to select a sample considering these points. Our approach is to frame SVDD sampling as an optimization problem, where constraints guarantee that sampling indeed approximates the original decision boundary. We then propose RAPID, an efficient algorithm to solve this optimization problem. RAPID does not require any tuning of parameters, is easy to implement and scales well to large data sets. We evaluate our approach on real-world and synthetic data. Our evaluation is the most comprehensive one for SVDD sampling so far. Our results show that RAPID outperforms its competitors in classification accuracy, in sample size, and in runtime.

In this paper, we present a concept for an assistance system for public transport passengers currently being developed for Kassel, Germany, and its surrounding area. The assistance system aims at increasing the attractiveness of local public transport by reducing barriers to use, thus promoting sustainable travel behavior. Three main barriers were identified: crowded vehicles, missed connections, and inconveniences in the transportation of shopping bags and luggage. To tackle these issues, three assistance system services were conceptualized: the occupancy rate informing passengers about the occupancy level of vehicles, the transfer connection monitor and secure system giving passengers the option to communicate transfer connection requests, and the delivery service allowing the use of public transport while shopping without the need to transport purchased goods. The three services are presented in detail along with the user interfaces they will be integrated into. Moreover, for the further implementation of the assistance system, a user requirement analysis is outlined. We finally give an overview and outlook regarding the implementation and evaluation of the concept in laboratory studies and a one-year field study.

Smart glasses are increasingly commercialized and may replace or at least complement smartphones someday. Common smartphone features, such as notifications, should then also be available for smart glasses. However, notifications are of disruptive character given that even unimportant notifications frequently interrupt users performing a primary task. This often leads to distractions and performance degradation. Thus, we propose a concept for displaying notifications in the peripheral field of view of smart glasses and with different visualizations depending on the priority of the notification. We developed three icon-based notifications representing increasing priority: a transparent green icon continuously becoming more opaque (low priority), a yellow icon moving up and down (medium priority), and a red and yellow flashing icon (high priority). To evaluate the concept, we conducted a study with 24 participants who performed a primary task and should react to notifications at the same time using the Nreal Light smart glasses. The results showed that reaction times for the low-priority notification were significantly higher and it was ranked as the least distracting. The medium- and high-priority notifications did not show a clear difference in noticeability, distraction, or workload. We discuss implications of our results for the perception and visualization of notifications in the peripheral field of view of smart glasses and, more generally, for augmented reality applications.

We propose a concept for displaying notifications in the peripheral field of view of smart glasses aiming to achieve a balance between perception and distraction depending on the priority of the notification. We designed three different visualizations for notifications of low, medium, and high priority. To evaluate this concept, we conducted a study with 24 participants who reacted to the notifications while performing a primary task. Reaction times for the low-priority notification were significantly higher. The medium- and high-priority notifications did not show a clear difference.

Attribute exploration is a method from Formal Concept Analysis (FCA) that helps a domain expert discover structural dependencies in knowledge domains which can be represented as formal contexts (cross tables of objects and attributes). In this paper we present an extension of attribute exploration that allows for a group of domain experts and explores their shared views. Each expert has their own view of the domain and the views of multiple experts may contain contradicting information.

Besides infrastructure-based solutions, small-scale microsystems are increasingly connected and interoperating with others in changing environments. Following the same motivation as for self-adaptive systems, this demands novel attempts to counter complexity and provide autonomous decision freedom that paves the path towards resilient and flexible behaviour. In this article, we outline a vision for research on self-aware microsystems (SAM) that aims at providing technical solutions that are especially relevant for initiatives such as self-improving system integration.

Pressure mapping smart textile is a new type of sensing modality that transforms the pressure distribution over surfaces into digital ”image” and ”video”, that has rich application scenarios in Human Activity Recognition (HAR), because all human activities are linked with force change over certain surfaces. To speed up its application exploration, we propose a toolkit named LwTool for the data processing, including: (a) a feature library, including 1830 ready-to-use temporal and spatial features, (b) a hierarchical feature selection framework that automatically picks out the best features for a new application from the feature library. As real-time processing capability is important for instant user feedback, we emphasize not only on good recognition result but also on reducing time cost when selecting features. Our library and algorithms are validated on Smart-Toy and Smart-Bedsheet applications, an 89.7% accuracy for Smart-Toy and an 83.8% accuracy for Smart-Bedsheet can be achieved (10-fold cross-validation) using our feature library. Adopting the feature selection algorithm, the processing speed is increased by more than 3 times while maintaining high accuracy for both two applications. We believe our method could be a general and powerful toolkit in building real-time recognition software systems for pressure mapping smart textile.

Knowledge computation tasks, such as computing a base of valid implications, are often infeasible for large data sets. This is in particular true when deriving canonical bases in formal concept analysis (FCA). Therefore, it is necessary to find techniques that on the one hand reduce the data set size, but on the other hand preserve enough structure to extract useful knowledge. Many successful methods are based on random processes to reduce the size of the investigated data set. This, however, makes them hardly interpretable with respect to the discovered knowledge. Other approaches restrict themselves to highly supported subsets and omit rare and (maybe) interesting patterns. An essentially different approach is used in network science, called k-cores. These cores are able to reflect rare patterns, as long as they are well connected within the data set. In this work, we study k-cores in the realm of FCA by exploiting the natural correspondence of bi-partite graphs and formal contexts. This structurally motivated approach leads to a comprehensible extraction of knowledge cores from large formal contexts.

The curse of dimensionality is a phenomenon frequently observed in machine learning (ML) and knowledge discovery (KD). There is a large body of literature investigating its origin and impact, using methods from mathematics as well as from computer science. Among the mathematical insights into data dimensionality, there is an intimate link between the dimension curse and the phenomenon of measure concentration, which makes the former accessible to methods of geometric analysis. The present work provides a comprehensive study of the intrinsic geometry of a data set, based on Gromov's metric measure geometry and Pestov's axiomatic approach to intrinsic dimension. In detail, we define a concept of geometric data set and introduce a metric as well as a partial order on the set of isomorphism classes of such data sets. Based on these objects, we propose and investigate an axiomatic approach to the intrinsic dimension of geometric data sets and establish a concrete dimension function with the desired properties. Our model for data sets and their intrinsic dimension is computationally feasible and, moreover, adaptable to specific ML/KD-algorithms, as illustrated by various experiments.

Fast Bayesian Updates for Deep Learning with a Use Case in Active Learning. Herde, Marek; Huang, Zhixin; Huseljic, Denis; Kottke, Daniel; Vogt, Stephan; Sick, Bernhard. In arXiv e-prints, p. arXiv:2210.06112. 2022.

Retraining deep neural networks when new data arrives is typically computationally expensive. Moreover, certain applications do not allow such costly retraining due to time or computational constraints. Fast Bayesian updates are a possible solution to this issue. Therefore, we propose a Bayesian update based on Monte-Carlo samples and a last-layer Laplace approximation for different Bayesian neural network types, i.e., Dropout, Ensemble, and Spectral Normalized Neural Gaussian Process (SNGP). In a large-scale evaluation study, we show that our updates combined with SNGP represent a fast and competitive alternative to costly retraining. As a use case, we combine the Bayesian updates for SNGP with different sequential query strategies to exemplarily demonstrate their improved selection performance in active learning.

The transport of magnetic particles (MPs) by dynamic magnetic field landscapes (MFLs) using magnetically patterned substrates is promising for the development of Lab-on-a-chip (LOC) systems. The inherent close-to-substrate MP motion is sensitive to changing particle–substrate interactions. Thus, the detection of a modified particle–substrate separation distance caused by surface binding of an analyte is expected to be a promising probe in analytics and diagnostics. Here, we present an essential prerequisite for such an application, namely the label-free quantitative experimental determination of the three-dimensional trajectories of superparamagnetic particles (SPPs) transported by a dynamically changing MFL. The evaluation of defocused SPP images from optical bright-field microscopy revealed a “hopping”-like motion of the magnetic particles, previously predicted by theory, additionally allowing a quantification of maximum jump heights. As our findings pave the way towards precise determination of particle–substrate separations, they bear deep implications for future LOC detection schemes using only optical microscopy.

Despite its undisputable benefits for firms, crowdsourcing is rarely applied in small and medium sized enterprises (SME), yet. Until today extant literature provides only an uncomplete picture of the barriers that hinder SMEs from adopting crowdsourcing. Because of these incomplete insights on this phenomenon there is a great deal of uncertainty on how to overcome these barriers all the more. In the scope of an interview series with 15 SMEs we explore a range of different barriers. The findings from our study do not only expand the so far incomplete body of knowledge but also provide practical references for SMEs to be aware of the barriers. This simplifies avoiding them and successfully adopting crowdsourcing.
A Review of Uncertainty Calibration in Pretrained Object Detectors. Huseljic, Denis; Herde, Marek; Muejde, Mehmet; Sick, Bernhard. In arXiv e-prints, p. arXiv:2210.02935. 2022.

In the field of deep learning based computer vision, the development of deep object detection has led to unique paradigms (e.g., two-stage or set-based) and architectures (e.g., Faster-RCNN or DETR) which enable outstanding performance on challenging benchmark datasets. Despite this, the trained object detectors typically do not reliably assess uncertainty regarding their own knowledge, and the quality of their probabilistic predictions is usually poor. As these are often used to make subsequent decisions, such inaccurate probabilistic predictions must be avoided. In this work, we investigate the uncertainty calibration properties of different pretrained object detection architectures in a multi-class setting. We propose a framework to ensure a fair, unbiased, and repeatable evaluation and conduct detailed analyses assessing the calibration under distributional changes (e.g., distributional shift and application to out-of-distribution data). Furthermore, by investigating the influence of different detector paradigms, post-processing steps, and suitable choices of metrics, we deliver novel insights into why poor detector calibration emerges. Based on these insights, we are able to improve the calibration of a detector by simply finetuning its last layer.

Dynamically organised multi-agent systems that consist of heterogeneous participants require cooperation to fulfil complex tasks. Such tasks are commonly subdivided into subtasks that have to be executed by individual agents. The necessary teamwork demands coordination of the involved team members. In contrast to typical approaches like agent-centric and organisation-centric views, our solution is based on the task-centric view and thus contains active task components which select agents focusing on their Skills. It enables an encapsulated description of the task flow and its requirements including team cooperation, organisation, and location-independent allocation processes. Besides agent properties that represent syntactical and semantic information, agent behaviours are considered as well. The main contributions of this paper are hyperplane-based machine-learned Behaviour Models that are generated to capture the behaviour and consider the Behaviour Implementations as black boxes. These Behaviour Models are provided by a distributed behaviour repository that enables tasks to actively select fitting Behaviour Implementations. We evaluated our approach based on agents playing chessboard-like games autonomously.

Crises become the norm for organizations, as recent years have shown. Especially the automotive industry is still facing disruptive changes such as e-mobility, connected cars or autonomous driving. Disrupted supply chains, related production downtimes and associated financial losses are consequences. Procurement departments are the interface between internal and external stakeholders in supply chains, and therefore, the central authority for managing crises. In such situations, effective decision-making is essential. Positive effects of data analytics on decision-making were part of numerous research endeavors, as well as related data analytics competencies. We conducted semi-structured interviews with experienced experts about relevant data analytics competencies in procurement departments. We present an overview specifically for procurement departments and derive implications of these competencies on decision-making. As a result, we apply our findings to existing research from a theoretical perspective and support procurement leaders and their departments in facing current and future challenges from a practical perspective.

This paper investigates how intersectional critical theoretical concepts from social sciences and humanities research can be worked with in machine learning systems design. It does so by presenting a case study of a series of speculative design workshops, conducted in 2021. These workshops drew on intersectional feminist methodologies to construct interdisciplinary interventions in the design of machine learning systems, towards more inclusive, accountable, and contextualized systems design. The concepts of “situating/situated knowledges”, "figuration", "diffraction", and “critical fabulation/speculation” were taken up as theoretical and methodological tools for concept-led design workshops. This paper presents the design framework of the workshops and highlights tensions and possibilities with regards to interdisciplinary machine learning systems design towards more inclusive, contextualized, and accountable systems. It discusses the role that critical theoretical concepts can play in a design process and shows how such concepts can work as methodological tools that nonetheless require an open-ended experimental space to function. It presents insights and discussion points regarding what it means to work with critical intersectional knowledge that is inextricably connected to its historical and socio-political roots, and how this reframes what it might mean to design fair and accountable systems.

Accelerated by the COVID-19 pandemic, anthropomorphic service robots are continuously penetrating various domains of our daily lives. With this development, the urge for an interdisciplinary approach to responsibly design human-robot interaction (HRI), with particular attention to human dignity, privacy, compliance, and transparency, increases. This paper contributes to design science, in developing a new artifact, i.e., an interdisciplinary framework for designing responsible HRI with anthropomorphic service robots, which covers the three design science research cycles. Furthermore, we propose a multi-method approach by applying this interdisciplinary framework. Thereby, our finding offer implications for designing HRI in a responsible manner.

In transductive active learning, the goal is to determine the correct labels for an unlabeled, known dataset. Therefore, we can either ask an oracle to provide the right label at some cost or use the prediction of a classifier which we train on the labels acquired so far. In contrast, the commonly used (inductive) active learning aims to select instances for labeling out of the unlabeled set to create a generalized classifier, which will be deployed on unknown data. This article formally defines the transductive setting and shows that it requires new solutions. Additionally, we formalize the theoretically cost-optimal stopping point for the transductive scenario. Building upon the probabilistic active learning framework, we propose a new transductive selection strategy that includes a stopping criterion and show its superiority.

Der Beitrag wendet sich dem ambivalenten Zusammenspiel von Privatheit und Digitalität zu, indem er deren Relevanz für Diskurse und Praktiken der Selbstbestimmung ausleuchtet und auf die soziotechnischen Transformationen dieses Zusammenspiels bezieht. Privatheit und Digitalität werden dabei als gesellschaftlich mitkonstituierte Sozialformen, Assemblagen oder Kommunikationsverhältnisse perspektiviert, die von historisch sich wandelnden soziokulturellen Einflussgrößen durchzogen sind. Um die skizzierte Perspektive einzunehmen werden wir zunächst die einschlägigen soziologischen Wissensbestände zu einer kursorischen Darstellung gesellschaftstheoretischer Perspektiven auf Privatheit verdichten. Daraufhin wenden wir uns den soziologischen Digitalisierungsforschungen zu, die die Konzeptualisierung von Privatheit nicht unberührt lassen. Hierbei wird v. a. herausgearbeitet, dass das soziologische und gesellschaftstheoretische Bild von Privatheit um Aspekte des Technischen und Materiellen erweitert werden muss. Theoretisch entsprechend eingestellt werden wir sodann eine Analyse von Selbstbestimmung unter soziodigitalen Verhältnissen präsentieren, die sich an vier zentralen Problemfeldern von Privatheit und Digitalität entfaltet: Die soziale Prämierung von Sichtbarkeit; soziale Konsequenzen digitaler Verhaltensformung; die soziale Dynamik datenökonomischer Erlösmodelle; sowie die Auswirkungen, die sich aus alldem für die Entscheidungsfreiheiten von Nutzenden ergeben. Im Fazit des Beitrags werden Konsequenzen für eine demokratische und an Selbstbestimmung orientierte Gestaltung von Privatheit benannt. Hierbei zeigt sich ein erheblicher Bedarf an einer Politik der Gestaltung und Regulierung von soziodigitalen Infrastrukturen, die eine Datenökonomie befördert, welche sich der demokratischen Kontrolle, Mitbestimmung und v. a. der Kritik öffnet. Zentrale Kompetenz individueller, wie kollektiver Selbstbestimmung wird damit die Fähigkeit zur Kritik der normierenden Gehalte und Effekte soziodigitaler Infrastrukturen. Diese muss aus den soziodigitalen Verhältnissen und praktischen Situationen selbst erwachsen und die Pluralität von Rechtfertigungsordnungen moderner Gesellschaften einbeziehen, um so die Kontingenz bestehender normativer Ordnungen erfahrbar und alternative Infrastrukturgestaltungspfade begehbar zu machen: Nur wenn die Infrastrukturen gewährleisten, dass der Faden zur kritischen Praxis nicht reißt, kann Privatheit unter soziodigitalen Bedingungen Ort der Selbstbestimmung bleiben.

Recently, businesses are introducing low-code development platforms (LCDP) that enable employees with little to no development expertise to develop their own systems to improve their work. These so-called business unit developers (BUDs) possess necessary domain knowledge to understand how to use LCDPs to create useful (self-) services. Using job resource demand theory and the job crafting model, we conceptualize that BUDs use of LCDPs can be framed using the theoretical lens of job crafting. Job crafting stems from vocational psychology and provides well-researched positive consequences, such as wellbeing and meaningfulness. Thus, our research objective is to understand how BUDs can use LCDPs to job craft to gain access to positive job crafting consequences. We interviewed 17 experts across three organizations that employ an LDCP for chatbots. Our results suggest that job crafting is a suitable framework for understanding the effects of LCDP use.

Dynamic Graph Neural Networks recently became more and more important as graphs from many scientific fields, ranging from mathematics, biology, social sciences, and physics to computer science, are dynamic by nature. While temporal changes (dynamics) play an essential role in many real-world applications, most of the models in the literature on Graph Neural Networks (GNN) process static graphs. The few GNN models on dynamic graphs only consider exceptional cases of dynamics, e.g., node attribute-dynamic graphs or structure-dynamic graphs limited to additions or changes to the graph's edges, etc. Therefore, we present a novel Fully Dynamic Graph Neural Network (FDGNN) that can handle fully-dynamic graphs in continuous time. The proposed method provides a node and an edge embedding that includes their activity to address added and deleted nodes or edges, and possible attributes. Furthermore, the embeddings specify Temporal Point Processes for each event to encode the distributions of the structure- and attribute-related incoming graph events. In addition, our model can be updated efficiently by considering single events for local retraining.

Participatory Design means recognizing that those who will be affected by a future technology should have an active say in its creation. Yet, despite continuous interest in involving people as future users and consumers into designing novel and innovative future technology, participatory approaches in technology design remain relatively underdeveloped in the German HCI community. This article brings together the diversity of voices, domains, perspectives, approaches, and methods that collectively shape Participatory Design in Germany. In the following, we (1) outline our understanding of participatory practice and how it is different from mere user involvement; (2) reflect current issues of participatory and fair technology design within the German Participatory Design community; and (3) discuss tensions relevant to the field, that we expect to arise in the future, and which we derived from our 2021 workshop through a speculative method. We contribute an introduction and an overview of current themes and a speculative outlook on future issues of Participatory Design in Germany. It is meant to inform, provoke, inspire and, ultimately, invite participation within the wider Computer Science community.

Dass wertorientierte Technikgestaltung kaum umhinkommt, die gesellschaftsstrukturellen Bedingungen mit zu reflektieren, unter denen sie agiert, ist bekannt. Der Vortrag überträgt diese Einsicht auf den Bereich der Privatheit, indem er die strukturhistorischen Konstellationen rekonstruiert, aus denen sich versch. Formen der informationellen Privatheit in unterschiedlichen Vergesellschaftungsphasen der Moderne jeweils herausgeschält haben. Bei den so identifizierten Privatheitsformen handelt es sich um a) Reputation Management; b) Rückzug; sowie c) individuelle Informationskontrolle. Basierend auf einer solchen Genealogie informationeller Privatheitspraktiken werden in einem weiteren Schritt die strukturellen Treiber zeitgenössischer Privatheit herausgearbeitet, deren Form solchermaßen als d) Unschärfegarantie erkennbar wird. Abschließend werden Konsequenzen diskutiert, die sich aus den somit herausgearbeiteten gesellschaftsstrukturellen Bedingungen zeitgenössischer Technikgestaltung ergeben.

Der vorliegende Beitrag stellt gleichzeitig eine Ehrbezeugung und eine Problemanalyse dar: Zum einen wollen wir damit unseren 2021 viel zu früh aus dem Leben geschiedenen Promotionsbetreuer und Kollegen Manfred Faßler ehren, zum anderen mithilfe der Denkwerkzeuge, an denen wir gemeinsam mit ihm bis zuletzt gearbeitet haben, einen Problemraum ausweisen, in dem zukünftige, soziodigital verfasste Demokratien sich entwickeln und bewähren müssen. Wir tun dies, indem wir zunächst einige kulturevolutionäre Entwicklungen der jüngeren Vergangenheit skizzieren, die das Demokratieformat in seiner hergebrachten Form unter Druck setzen. Im nächsten Schritt werden wir einige Implikationen und Problemlagen herausarbeiten, die in der Folge zutage treten. Im resümierenden Schlussteil werden wir zusammenfassen und die gewonnenen Erkenntnisse diskutieren, um so einen Problemkatalog vorzulegen, dem sich sowohl die Forschungsbemühungen als auch die „ontological politics“ (A. Mol) der Zukunft tunlichst widmen sollten.

Citizen participation in increasingly digitalized governmental environments can introduce fruitful capabilities to encourage citizens to engage in municipal affairs and through this take actively part in fostering smart cities’ effectiveness. However, the practical exploitation of recent knowledge is still not sufficiently operationalized, whilst research in this field yields various approaches focusing on diverse emphases. Therefore, the necessity of systematically collecting and afterwards analysing the existing literature towards this topic is obvious. This paper depicts a proceeding to systematically review the available literature towards the relevant research units on citizen participation. Overall, 48 topic-based papers were identified out of leading journals and conference papers about information systems. The main findings of the relevant papers were assessed to a proposed analytical framework consisting of increasing participation stages and two distinct focus groups namely government and citizens. Accordingly, the covered recent focus areas of research are identified to reveal where state-of-the-art research falls short. Consequently, the imperative of emphasising investigation regarding concepts for ICT-enabled services focusing the empowerment of citizens arises as being our contribution for guiding future research, whilst governments can practically benefit from the composed framework by using it for classifying, planning and implementing proposed participation activities.
Enhancing Active Learning with Weak Supervision and Transfer Learning by Leveraging Information and Knowledge Sources. Rauch, Lukas; Huseljic, Denis; Sick, Bernhard. In Workshop on Interactive Adaptive Learning (IAL), ECML PKDD, pp. 27–42. 2022.

One of the major limitations of deploying a machine learning model is the availability of labeled training data and the resulting expensive annotation process. Although active learning (AL) methods may reduce the annotation cost by actively selecting the most-useful instances, a costly human annotator usually provides the labels. Therefore, even with AL, we still consider the annotation process to be time-consuming and expensive. Besides human annotators, though, companies often have a vast amount of information and knowledge sources available that can generate low-cost labels (e.g., a black-box model) or improve the learning process (e.g., a pre-trained model). We present a novel approach that enhances AL with weak supervision (WS) and transfer learning (TL) to reduce the annotation cost by leveraging these sources. Specifically, we consider a black-box model like a rule-based system as an error-prone and weakly-supervised annotator that inexpensively provides labels. We estimate its performance with an annotator model to decide whether a human annotation is required. Additionally, we utilize unlabeled internal and external data by transferring knowledge from a pre-trained model to the AL cycle. We sequentially investigate the impact of WS and TL on annotation cost and model performance in an AL cycle through a use case. Our evaluation shows that our approach can reduce annotation cost by 51% while achieving nearly identical model performance compared to a traditional AL approach.
Understanding the Necessary Conditions of Multi-Source Trust Transfer in Artificial Intelligence. Renner, Maximilian; Lins, Sebastian; Söllner, Matthias; Thiebes, Scott; Sunyaev, Ali.

Trust plays an increasingly important role, especially in new emerging AI-capable technologies. While different frameworks on establishing trustworthy AI were developed, extant research mostly neglects trust transfer mechanisms. We focus on multi-source trust transfer while taking a dual trust perspective including trust in provider and trust in technology. Our study falls in the context of autonomous vehicles as a target and AI and vehicles as sources. While conducting a survey with 432 participants, we applied necessary condition analysis to understand which sources are necessary for a multi-source trust transfer. Our results indicate that for trust in technology, AI and vehicle technology are necessary sources. In contrast, for trust in provider, only vehicle provider represents a necessary source. We contribute to research by providing a fresh perspective on trust in AI-capable technologies, applying a novel data analysis method to reveal necessary trust sources, and consider duality of trust in trust transfer.

Trajectory data analysis is an essential component for highly automated driving. Complex models developed with these data predict other road users’ movement and behavior patterns. Based on these predictions — and additional contextual information such as the course of the road, (traffic) rules, and interaction with other road users — the highly automated vehicle (HAV) must be able to reliably and safely perform the task assigned to it, e.g., moving from point A to B. Ideally, the HAV moves safely through its environment, just as we would expect a human driver to do. However, if unusual trajectories occur, so-called trajectory corner cases, a human driver can usually cope well, but an HAV can quickly get into trouble. In the definition of trajectory corner cases, which we provide in this work, we will consider the relevance of unusual trajectories with respect to the task at hand. Based on this, we will also present a taxonomy of different trajectory corner cases. The categorization of corner cases into the taxonomy will be shown with examples and is done by cause and required data sources. To illustrate the complexity between the machine learning (ML) model and the corner case cause, we present a general processing chain underlying the taxonomy.

Examining Trust in Conversational Systems: Conceptual and Empirical Findings on User Trust, Related Behavior, and System Trustworthiness. Schmitt, Anuschka. In AAAI/ACM Conference on AI, Ethics, and Society (AIES). Oxford, United Kingdom, 2022.

Machine learning (ML)-based conversational systems represent a value enabler for human-machine interaction. Simultaneously, the opacity, complexity, and humanness accompanied by such systems introduce their own issues, including trust misalignment. While trust is viewed as a prerequisite for effective system use, few studies have considered calibrating for appropriate trust, and empirically testing the relationship between trust and related behavior. Moreover, the desired implications of transparency-enhancing design cues are ambiguous. My research aims to explore the impact of system performance on trust, the dichotomy between trust and behavior, and how transparency might help attenuate the effects caused by low system performance in the specific context of decision-making tasks assisted by ML-based conversational systems.

Machine learning (ML)-based software’s deployment has raised serious concerns about its pervasive and harmful consequences for users, business, and society inflicted through bias. While approaches to address bias are increasingly recognized and developed, our understanding of debiasing remains nascent. Research has yet to provide a comprehensive coverage of this vast growing field, much of which is not embedded in theoretical understanding. Conceptualizing and structuring the nature, effect, and implementation of debiasing instruments could provide necessary guidance for practitioners investing in debiasing efforts. We develop a taxonomy that classifies debiasing instrument characteristics into seven key dimensions. We evaluate and refine our taxonomy through nine experts and apply our taxonomy to three actual debiasing instruments, drawing lessons for the design and choice of appropriate instruments. Bridging the gaps between our conceptual understanding of debiasing for ML-based software and its organizational implementation, we discuss contributions and future research.
Designing for Conversational System Trustworthiness: The Impact of Model Transparency on Trust and Task Performance. Schmitt, Anuschka; Wambsganss, Thiemo; Janson, Andreas. In European Conference on Information Systems (ECIS). Timișoara, Romania, 2022.

Designing for system trustworthiness promises to address challenges of opaqueness and uncertainty introduced through Machine Learning (ML)-based systems by allowing users to understand and interpret systems’ underlying working mechanisms. However, empirical exploration of trustworthiness measures and their effectiveness is scarce and inconclusive. We investigated how varying model confidence (70% versus 90%) and making confidence levels transparent to the user (explanatory statement versus no explanatory statement) may influence perceptions of trust and performance in an information retrieval task assisted by a conversational system. In a field experiment with 104 users, our findings indicate that neither model confidence nor transparency seem to impact trust in the conversational system. However, users’ task performance is positively influenced by both transparency and trust in the system. While this study considers the complex interplay of system trustworthiness, trust, and subsequent behavioral outcomes, our results call into question the relation between system trustworthiness and user trust.

Text-based conversational agents (CAs) are widely deployed across a number of daily tasks, including information retrieval. However, most existing agents follow a default design that disregards user needs and preferences, ultimately leading to a lack of usage and an unsatisfying user experience. To better understand how CAs can be designed in order to lead to effective system use, we deduced relevant design requirements from both literature and 13 user interviews. We built and tested a question-answering, text-based CA for an information retrieval task in an education scenario. Results from our experimental test with 41 students indicate that following a user-centered design has a significant positive effect on enjoyment and trust in a CA as opposed to deploying a default CA. If not designed with the user in mind, CAs are not necessarily more beneficial than traditional question-answering systems. Beyond practical implications for effective CA design, this paper points towards key challenges and potential research avenues when deploying social cues for CAs.

Die Digitalisierung verändert unsere Gesellschaft, die Art wie wir miteinander kommunizieren und wie wir arbeiten. Dabei birgt Digitalisierung nicht nur Vorteile, sondern führt auch dazu, dass jedes Individuum durch sein Agieren in der digitalen Welt Datenspuren hinterlässt. Diese Daten werden gesammelt, aggregiert und ausgewertet, und das vielfach, ohne dass sich Individuen dessen bewusst sind. Hier kann das sogenannte Privacy Nudging genutzt werden, durch das Nutzende „angestupst“ werden, um ihr Verhalten so zu verändern, dass sie ihre eigenen Daten besser schützen. Bei der Gestaltung von Nudging Konzepten gibt es zahlreiche rechtliche, ethische und soziotechnische Hürden, die es zu berücksichtigen gilt. Hierzu existieren bisher keine einheitlichen Richtlinien und Empfehlungen. Entsprechend präsentiert der Beitrag eine integrative soziotechnische Gestaltungsperspektive für digitale privacy Nudges, indem Technik, Ethik und Recht nicht mehr nur isoliert betrachtet werden.

With the advent of artificial intelligence (AI), individuals are increasingly teaming up with AI-based systems to enhance their creative collaborative performance. When working with AI-based systems, several aspects of team dynamics need to be considered, which raises the question how humans’ approach and perceive their new teammates. In an experimental setting, we investigate the influence of social presence in a group ideation process with an AI-based teammate and examine its effects on the motivation to contribute. Our results show a multi-mediation model in which social presence indirectly influences whether human team members are motivated to contribute to a team with AI-based teammates, which is mediated by willingness to depend and team-oriented commitment.

This paper employs a longitudinal perspective to examine continued system use (CSU) by individuals in utilitarian, volitional contexts when alternative systems are present . We focus on two key behavioural antecedents of CSU – habit and continuance intention – and theorise how the relationships between CSU and these antecedents evolve over time. In addition, we hypothesise how the interaction effect of habit and intention on CSU evolves temporally. Our theorising differs from extant literature in two important respects: 1) In contrast to the widespread acceptance of the diminishing effect of continuance intention on CSU in the information systems (IS) literature, we hypothesise that in our context, its impact increases with time; and 2) In contrast to the negative moderation effect of habit on the relationship between intention and CSU proposed in the literature, we posit a positive interaction effect. We collect longitudinal survey data on the use of a higher education IS from students in a European university. Our results suggest that the impact of continuance intention on CSU as well as the interaction effect between habit and intention are increasing over time. We further introduce a methodological innovation – the permutation approach to conduct the multi-group analysis with repeated measures – to the literature.
LG4AV: Combining Language Models and Graph Neural Networks for Author Verification. Stubbemann, Maximilian; Stumme, Gerd. In Advances in Intelligent Data Analysis XX, T. Bouadi, E. Fromont, E. Hüllermeier (eds.), pp. 315–326. Springer International Publishing, Cham, 2022.

The verification of document authorships is important in various settings. Researchers are for example judged and compared by the amount and impact of their publications and public figures are confronted by their posts on social media. Therefore, it is important that authorship information in frequently used data sets is correct. The question whether a given document is written by a given author is commonly referred to as authorship verification (AV). While AV is a widely investigated problem in general, only few works consider settings where the documents are short and written in a rather uniform style. This makes most approaches impractical for bibliometric data. Here, authorships of scientific publications have to be verified, often with just abstracts and titles available. To this point, we present LG4AV which combines language models and graph neural networks for authorship verification. By directly feeding the available texts in a pre-trained transformer architecture, our model does not need any hand-crafted stylometric features that are not meaningful in scenarios where the writing style is, at least to some extent, standardized. By the incorporation of a graph neural network structure, our model can benefit from relations between authors that are meaningful with respect to the verification process.

Graphs are ubiquitous in nature and can therefore serve as models for many practical but also theoretical problems. Based on this, the young research field of Graph Neural Networks (GNNs) has emerged. Despite the youth of the field and the speed in which new models are developed, many good surveys have been published in the last years. Nevertheless, an overview on which graph types can be modeled by GNNs is missing. In this survey, we give a detailed overview of already existing GNNs and, unlike previous surveys, categorize them according to their ability to handle different graph types and properties. We consider GNNs operating on static as well as on dynamic graphs of different structural constitutions, with or without node or edge attributes. Moreover in the dynamic case, we separate the models in discrete-time and continuous-time dynamic graphs based on their architecture. While ordering the existing GNN models, we find, that there are still graph types, that are not or only rarely covered by existing GNN models. We point out where models are missing and give potential reasons for their absence.

Recent advantages from computational linguists can be leveraged to nudge students with adaptive self evaluation based on their argumentation skill level. To investigate how individual argumentation self evaluation will help students write more convincing texts, we designed an intelligent argumentation writing support system called ArgumentFeedback based on nudging theory and evaluated it in a series of three qualitative and quaxntitative studies with a total of 83 students. We found that students who received a self-evaluation nudge wrote more convincing texts with a better quality of formal and perceived argumentation compared to the control group. The measured self-efficacy and the technology acceptance provide promising results for embedding adaptive argumentation writing support tools in combination with digital nudging in traditional learning settings to foster self-regulated learning. Our results indicate that the design of nudging-based learning applications for self-regulated learning combined with computational methods for argumentation self-evaluation has a beneficial use to foster better writing skills of students.
How IT carve-out project complexity influences divestor performance in M&As. Yetton, Philip; Henningsson, Stefan; Böhm, Markus; Leimeister, Jan Marco; Krcmar, Helmut. In European Journal of Information Systems (EJIS), 32(6), pp. 926–988. 2022.

IT carve-out projects are complex and cost-intensive components of M&A transactions. Existing research sheds little light on the determinants of IT carve-out project complexity and/or its effects on divestor performance. Instead, research has focused on the post-acquisition IT integration project and acquirer performance. This paper presents the first divestor-centric model of IT transactions from the divestor to the acquirer when a Business Unit in a Multi-Business Organization (MBO) is carved out and integrated into another MBO. The model explains how divestor business and IT alignment pre-conditions contribute to increased IT carve-out project complexity. Such complexity increases IT carve-out project time to physical IT separation and creates IT stranded assets, which decrease post-divestment business, IT alignment and divestor performance. The current recommended strategy of adopting transitional service agreements (TSAs) to handle IT carve-out complexity is compared with two new proactive strategies derived from the model. TSA-based strategies restrict the divestor from both decommissioning IT stranded assets and reconfiguring its IT assets to support its new post-divestment business strategy. The two new strategies address IT carve-out complexity without incurring the negative effects from adopting TSAs.

This article presents a holistic approach for probabilistic cyclist intention detection. By combining probabilities for the current cyclist motion states with a probabilistic ensemble trajectory forecast, we are able to generate reliable estimates of cyclists’ future positions. The probabilities are used as weights in the probabilistic ensemble trajectory forecast. The ensemble consists of specialized models, which produce individual forecasts in the form of Gaussian distributions under the assumption of a certain motion state of the cyclist (e.g. cyclist is starting). By weighting the specialized models, we create forecasts in the form of Gaussian mixtures that define regions within which the cyclists will reside with a certain probability. To evaluate our method, we rate the reliability, sharpness, and positional accuracy of our forecasted distributions. We compare our method to a widely used unimodal approach which produces forecasts in the form of Gaussian distributions and show that our method is able to produce more reliable and sharper outputs while retaining comparable positional accuracy. By comparing two different methods for basic movement detection, one based on the past cyclist trajectory and one using past image sequences, we demonstrate that the results can be further improved by incorporating video information. Our methods are evaluated using a dataset created at a public intersection. The code and the dataset are publicly available.

Digital nudging is a promising approach from behavioral economics. In deci-sions where individuals tend to struggle, nudges can support users of digital systems by aligning their behavior with their preferences. Despite their wide use, most digital nudges are designed to support the intended behavior from the perspective of a company while neglecting potential legal, ethical, or individual constraints or preferences. With modern technologies such as artificial intelli-gence or big data, these issues multiply and with the increasing effectiveness of digital nudges and use of new technologies, this has become even more critical. Thus, in this paper we follow a Design Science Research approach to develop a process model for the systematic development of legitimate nudges (DELEN). Legitimacy requires that dealings between different entities shall be fair. Unlike other models, we set normative boundaries derived from literature, expert in-terviews, and target group segmentation as integral elements. Target group seg-mentation increases nudge effectiveness and avoids unnecessary burdens for other individuals. By doing so, the DELEN process model paves the way for legitimate and effective digital nudges.

In this work, we tested two digital privacy nudges: a social and a framing nudge. To empirically measure the effectiveness of the two privacy nudges, we developed an online experiment. We evaluated 223 data sets with the partial least squares structural equation modeling (PLS-SEM) and a two-factorial Analysis of Variance (ANOVA). The results indicate that privacy nudges negatively influence information disclosure behavior. The privacy framing nudge has a direct and indirect effect, while the privacy social nudge has only an indirect effect on the information disclosure behavior. Individuals exposed to the privacy nudges perceived the stimulus as threat. Importantly, both nudges spark negative feelings. With this research, we are contributing to the discussion of what drives privacy nudge effectiveness and influences information disclosure behavior in digital work environments.
What do you mean? A Review on Recovery Strategies to Overcome Conversational Breakdowns of Conversational Agents. Benner, Dennis; Elshan, Edona; Schöbel, Sofia; Janson, Andreas. In International Conference on Information Systems (ICIS). 2021.

Since the emergence of conversational agents, this technology has seen continuous development and research. Today, advanced conversational agents are virtually omnipresent in our everyday lives. Albeit the numerous improvements in their conversational capabilities, breakdowns are still a persistent issue. Such breakdowns can result in a very unpleasant experience for users and impair the future success of conversational agents. This issue has been acknowledged by many researchers recently. However, the research on strategies to overcome conversational breakdowns is still inconclusive, and further research is needed. Therefore, we conduct a systematic literature analysis to derive conceptual conversational breakdown recovery strategies from literature and highlight future research avenues to address potential gaps. Thus, we contribute to theory of human-agent interaction by deriving and assessing recovery strategies and suggesting leads for novel recovery strategies.
A Theory-Driven Design Science Research Agenda Towards Gamified Videos. Benner, Dennis; Schöbel, Sofia. In International Conference on Wirtschaftsinformatik (WI). Duisburg-Essen, Germany, 2021.
- [ Abstract ]
- [ BibSonomy-Post ]
Digitalization has opened new opportunities but also brought new challenges such as lower engagement of students in online training. Especially learning videos need to be changed in their design and structure to make them more engaging for users. So far, overarching design principles are missing that support the development of gamified learning videos. In our research in progress paper we present an overarching approach on how to develop meaningful gamified learning videos. With our design science research approach, we plan to derive design principles and design features from our state-of-the-art design requirements. Additionally, we will conduct a field experiment to put our theoretical contributions to test and gather practical insights. Our research contributes to theory, by clarifying how and why gamified videos can support better learning. In a long run, practical contributions can be given to developers about how to construct gamified learning videos.

Driven by technological advances, smart personal assistants (SPA) have gained importance in human-computer interaction. SPAs can influence user behavior and persuade them towards an outcome. However, users often lack motivated to interact with SPAs. One way to support this interaction is persuasive system design; considering concepts as gamification and/or digital nudging. Although SPA research has increased recently, there is still no shared knowledge about persuasive designs. Therefore, we aim to identify the current state-of-the-art for persuasive SPA design to understand how interactions and designs can be improved referring to persuasive system design. Thus, we conduct a systematic literature analysis to represent how gamification and digital nudging are used to design SPAs and conclude if and how those concepts can support SPA interactions. Consequently, we contribute to theory, providing better understanding about SPA interaction and design making SPAs more engaging and entertaining. Practitioners can use this contribution for persuasive SPA designs.
It is only for your own good, or is it? Ethical Considerations for Designing Ethically Conscious Persuasive Information Systems. Benner, Dennis; Schöbel, Sofia; Janson, Andreas. In Americas Conference on Information Systems (AMCIS). Association for Information Systems, Montreal, Kanada, 2021.

Persuasive designs, including gamification and digital nudging, have become well renowned during the last years and have been implemented successfully across different sectors including education, e-health, e-governance, e-finance and general information systems. In this regard, persuasive design can support desirable changes in attitude and behavior of users in order to achieve their own goals. However, such persuasive influence on individuals raises ethical questions as persuasive designs can impair the autonomy of users or persuade the user towards goals of a third party and hence lead to unethical decision-making processes. In human-computer interaction this is especially significant with the advent of advanced artificial intelligence that can emulate human behavior and thus bring new dynamics into play. Therefore, we conduct a systematic literature analysis with the goal to compile an overview of ethical considerations for persuasive system design, derive potential guidelines for ethical persuasive designs and shed light on potential research gaps.

Exploring the Impact of Crowd Members’ Motivation on Idea Quality in Online Innovation Communities. Bretschneider, Ulrich. In Annual Meeting of the Academy of Management (AOM). 2021.
- [ Abstract ]
- [ BibSonomy-Post ]
Since many years, several firms host Virtual Idea Communities (VIC), in which the crowd focuses on voluntarily developing ideas for new product development (NPD). Both, scholars and practitioners share a strong interest in understanding the factors that enhance crowd members’ individual ideation outcome, meaning the quality of ideas, since the value of user ideas is not only essential for the survival of a VIC, but it also directly affects the innovation effects of firm’s NPD. Although there exist first insights on what influences idea quality, empirical studies that provide evidence of which forms of crowd members motivations are positively linked to higher ideation outcome are neglected. In this research, we build a theoretical model explaining which motives of crowd members for engaging in ideation have a positive impact on the quality of ideas they developed. To test our theory, we employed empirical data from users of the VIC by the software manufacturer SAP. For the first time, we found that crowd members of VIC are motivated to send capability signals through their ideas and thus be more creative. Further, crowd members with higher levels of fun and learning motivation produce ideas of higher quality, whereas this association depends on their level of flow experience. Our empirical results provide important contributions to IS research and practice. On the basis of our findings it is possible to design socio-technical artefacts for VICs that stimulate users’ capability-, fun- and learning motives and in turn will lead to ideas of higher quality.

A person's name embodies identity. During user studies in Human Computer Interaction (HCI), persons are often renamed (pseudonymization) to hide their identity for privacy and ethical reasons. Pseudonymization occurs mostly as a “silent” affair of due diligence. Researchers barely give substantial information to the process nor reveal a reflexive position nor acknowledge the underlying elements of power and identity negotiation. As HCI advances in mitigating the design of biased technologies and breaking oppressive structures, I argue, in this paper, the need for the field to re-consider research requirements such as pseudonymization as possible to embody oppressive structures and erase identity. I present a review of papers from the 2020 CHI Conference on Human Factors in Computing Systems (CHI ‘20) that illustrate how silent the HCI approach is. My argument is built on Critical Race Theory, questioning the objectivity of such technical requirements. I use personal narratives to bolster this argument, ending with a call to the HCI community to acknowledge the power and privilege in renaming participants with three recommendations for consideration.

The advancing awareness of diversity in HCI is touted as laudable in addressing inequality and the digital divide. This progress however has not been reflected in HCI research. Diversity in HCI has focused on giving underrepresented users voice and confronting homogeneity. By increasing representations, though a diversity affinity is immediately visible, the deconstruction of institutionalized prejudice fails. Additionally, underrepresented voices have the unsurmountable task of representing their group. These approaches to diversity become tokenistic fixes failing to tackle the systemic causes of inequality.

Eine der kritischsten Aufgaben für Start-ups ist die Validierung ihres Geschäftsmodells. Daher versuchen Gründer, Informationen wie z. B. Feedback von anderen Akteuren zu sammeln, um die Gültigkeit ihrer Annahmen zu bewerten und Entscheidungen zu treffen. Bisherige Arbeiten über Entscheidungshilfen für die Validierung von Geschäftsmodellen bieten jedoch keine Lösung für den höchst unsicheren und komplexen Kontext von Start-ups in der Frühphase. Der Zweck dieser Studie ist daher die Entwicklung von Entwurfsprinzipien für ein hybrides Entscheidungsunterstützungssystem (HIDSS), das die komplementären Fähigkeiten von menschlicher und maschineller Intelligenz kombiniert. Wir verfolgen einen gestaltungsorientierten Forschungsansatz, um ein Prototyp-Artefakt und eine Reihe von Designprinzipien zu entwerfen. Unsere Studie liefert präskriptives Wissen für HIDSS und trägt zu früheren Arbeiten über Entscheidungsunterstützung für Geschäftsmodelle, über die Anwendung der komplementären Stärken von Mensch und Maschine zur Entscheidungsfindung und über Unterstützungssysteme für extrem unsichere Entscheidungsprobleme bei.

Higher legal standards regarding the data protection of individuals, such as the European General Data Protection Regulation, increase the pressure on developing lawful systems. In the development of technologies, not only developers are involved. It also requires knowledge from other stakeholders, such as legal experts, that lack technical knowledge but are required to understand IT artifacts. We see two strings that can benefit from the use of design patterns: first, the well-known use of design patterns to support developers in case of recurring problems. Second, we see potential that legal experts, who have to interact with and understand complicated, novel technologies, benefit from the same patterns. We conduct a revelatory case study using design patterns to develop and assess a smart learning assistant. We scaffolded the case interpretation through the human-centered view of socio-materiality and provide contributions concerning the use of design patterns in the development and assessment of lawful technologies.

Due to its rising importance in science and technology in recent years, particle tracking in videos presents itself as a tool for successfully acquiring new knowledge in the field of life sciences and physics. Accordingly, different particle tracking methods for various scenarios have been developed. In this article, we present a particle tracking application implemented in Python for, in particular, spherical magnetic particles, including superparamagnetic beads and Janus particles. In the following, we distinguish between two sub-steps in particle tracking, namely the localization of particles in single images and the linking of the extracted particle positions of the subsequent frames into trajectories. We provide an intensity-based localization technique to detect particles and two linking algorithms, which apply either frame-by-frame linking or linear assignment problem solving. Beyond that, we offer helpful tools to preprocess images automatically as well as estimate parameters required for the localization algorithm by utilizing machine learning. As an extra, we have implemented a technique to estimate the current spatial orientation of Janus particles within the x-y-plane. Our framework is readily extendable and easy-to-use as we offer a graphical user interface and a command-line tool. Various output options, such as data frames and videos, ensure further analysis that can be automated.

Order diagrams allow human analysts to understand and analyze structural properties of ordered data. While an expert can create easily readable order diagrams, the automatic generation of those remains a hard task. In this work, we adapt force-directed approaches, which are known to generate aesthetically-pleasing drawings of graphs, to the realm of order diagrams. Our algorithm ReDraw thereby embeds the order in a high dimension and then iteratively reduces the dimension until a two-dimensional drawing is achieved. To improve aesthetics, this reduction is equipped with two force-directed steps where one step optimizes the distances of nodes and the other one the distances of lines in order to satisfy a set of a priori fixed conditions. By respecting an invariant about the vertical position of the elements in each step of our algorithm we ensure that the resulting drawings satisfy all necessary properties of order diagrams. Finally, we present the results of a user study to demonstrate that our algorithm outperforms comparable approaches on drawings of lattices with a high degree of distributivity.

The Effect of Explanations on Trust in an Assistance System for Public Transport Users and the Role of the Propensity to Trust. Faulhaber, A. K.; Ni, I.; Schmidt, L.

The present study aimed to investigate whether explanations increase trust in an assistance system. Moreover, we wanted to take the role of the individual propensity to trust in technology into account. We conducted an empirical study in a virtual reality environment where 40 participants interacted with a specific assistance system for public transport users. The study was in a 2x2 mixed design with the within-subject factor assistance system feature (trip planner and connection request) and the between-subject factor explanation (with or without). We measured trust as explicit trust via a questionnaire and as implicit trust via an operationalization of the participants’ behavior. The results showed that trust propensity predicted explicit trust, and explanations increased explicit trust significantly. This was not the case for implicit trust, though, suggesting that explicit and implicit trust do not necessarily coincide. In conclusion, our results complement the literature on explainable artificial intelligence and trust in automation and provide topics for future research regarding the effect of explanations on trust in assistance systems or other technologies.
Perception of Peripheral Visual Cues in Augmented Reality During Walking: A Pilot Study. Faulhaber, A. K.; Schmidt, L. In Arbeit HUMAINE gestalten: 67.

Augmented Reality (AR) glasses may be used in diverse mobile and multitasking contexts, for example, while walking. In such contexts, it is particularly important to display information without obscuring essential areas of central vision. Information can, thus, be presented to the peripheral vision. The objective of the present study was to investigate how peripheral visual cues should be displayed in AR to achieve efficient perception during walking. We conducted a pilot study and tested three different versions of directional cues presented while walking or standing still: simply popping up, moving towards the indicated direction, or changing color. The results indicated that the perception of peripheral cues in AR is generally less efficient while walking than standing still. Within the walking condition, the color-changing cue was perceived best.

In der hier vorgestellten Laborstudie wurden zwei Arten markerbasierter Augmented-Reality-Ergänzungen zu einem Lehrbuch mit einer konventionellen Ergänzung in Papierform verglichen. Hierbei wurden drei Unterthemen aus der Ausbildung zum Kraftfahrzeugmechatroniker ausbalanciert um je eine Art der Zusatzinformation ergänzt. Dabei wurde der Lernerfolg mit Multiple-Choice-Aufgaben kontrolliert sowie die Gebrauchstauglichkeit (SUS), die Beanspruchung (NASA-rTLX), die räumliche Vorstellung (RV) und das Nutzererlebnis (UEQ) mit Fragebögen im Within-Subject Design (N = 24) erhoben. Die Ergebnisse zeigen ein höheres Nutzererlebnis und eine bessere räumliche Vorstellung bei Verwendung der AR im Vergleich zur konventionellen Ergänzung bei jeweils vergleichbarer niedriger Beanspruchung, hoher Gebrauchstauglichkeit sowie Lernleistung.

Voice assistants are a novel class of information systems that fundamentally change human–computer interaction. Although these assistants are widespread, the utilization of these information systems is oftentimes only considered on a surface level by individuals. In addition, prior research has focused predominantly on initial use instead of looking deeper into post-adoption and habit formation. In consequence, this paper reviews how the notion of habit has been conceptualized in relation to biographical utilization of voice assistants and presents findings based on a qualitative study approach. From a perspective of post-adoption users, the study suggests that existing habits persist, and new habits hardly ever form in the context of voice assistant utilization. This paper outlines four key factors that help explain voice assistant utilization behavior and furthermore provides practical implications that help to ensure continued voice assistant use in the future.

Self-improving system integration (SISSY) aims at mastering the challenges of system organisation decisions for subsystems with highly dynamic behaviours. This is achieved by increased decision freedom of these subsystems, i.e., by moving the corresponding design decisions from design-time to run-time and from engineers to the systems themselves. As a result, a more robust and efficient constellation of the overall system organisation is maintained even under the presence of continuous change and disturbed conditions. Appropriate integration decisions require a solid foundation of assessing the current conditions and their dynamics using identifying triggers for a necessary evaluation of their own integration status. With this article, we present mCANDIES, a modular novelty detection technique especially suited for SISSY systems that fulfils exactly these identification tasks. mCANDIES tackles an anomaly or novelty detection problem in a modular way by combining the advantages of different detection approaches by exploiting locality in different regions of the input space — depending on, e.g. the density or location of expected observations. This is augmented with information about changes in the underlying model of the observations, i.e., mCANDIES identifies concept drifts. The corresponding information can then be used to trigger online learning behaviour. We analyse the behaviour of mCANDIES on artificial and real-world data sets and compare it to other techniques from the state of the art.

Catastrophic forgetting means that a trained neural network model gradually forgets the previously learned tasks when being retrained on new tasks. Overcoming the forgetting problem is a major problem in machine learning. Numerous continual learning algorithms are very successful in incremental learning of classification tasks, where new samples with their labels appear frequently. However, there is currently no research that addresses the catastrophic forgetting problem in regression tasks as far as we know. This problem has emerged as one of the primary constraints in some applications, such as renewable energy forecasts. This article clarifies problem-related definitions and proposes a new methodological framework that can forecast targets and update itself by means of continual learning. The framework consists of forecasting neural networks and buffers, which store newly collected data from a non-stationary data stream in an application. The changed probability distribution of the data stream, which the framework has identified, will be learned sequentially. The framework is called CLeaR (Continual Learning for Regression Tasks), where components can be flexibly customized for a specific application scenario. We design two sets of experiments to evaluate the CLeaR framework concerning fitting error (training), prediction error (test), and forgetting ratio. The first one is based on an artificial time series to explore how hyperparameters affect the CLeaR framework. The second one is designed with data collected from European wind farms to evaluate the CLeaR framework's performance in a real-world application. The experimental results demonstrate that the CLeaR framework can continually acquire knowledge in the data stream and improve the prediction accuracy. The article concludes with further research issues arising from requirements to extend the framework.

Magnetic Janus particles (MJPs), fabricated by covering a non-magnetic spherical particle with a hemispherical magnetic in-plane exchange-bias layer system cap, display an onion magnetization state for comparably large diameters of a few microns. In this work, the motion characteristics of these MJPs will be investigated when they are steered by a magnetic field landscape over prototypical parallel-stripe domains, dynamically varied by superposed external magnetic field pulse sequences, in an aqueous medium. We demonstrate, that due to the engineered magnetization state in the hemispherical cap, a comparably fast, directed particle transport and particle rotation can be induced. Additionally, by modifying the frequency of the applied pulse sequence and the strengths of the individual field components, we observe a possible separation between a combined or an individual occurrence of these two types of motion. Our findings bear importance for lab-on-a-chip systems, where particle immobilization on a surface via analyte bridges shall be used for low concentration analyte detection and a particle rotation over a defined position of a substrate may dramatically increase the immobilization (and therefore analyte detection) probability.

Die Digitalisierung verändert nicht nur unser privates, sondern auch unser Arbeitsleben. Immer mehr Daten über Individuen sind online verfügbar und werden für die Nutzung von bestimmten Online Services vorausgesetzt. Hierbei verlieren die Nutzenden oft den Überblick, wie und welche Daten sie von sich preisgeben. Dies birgt nicht nur das Risiko der Preisgabe von privaten Daten, sondern auch unternehmensseitig das Risiko, dass wichtige Daten außerhalb des Unternehmens veröffentlicht werden. Hier kann das Konzept des digitalen Nudgings angewandt werden, welches nunmehr auch als edukatives Privacy Nudging genutzt werden kann. Das Konzept bezweckt, Individuen durch bestimmte Elemente wie beispielsweise Defaults zu Verhaltensänderungen anzuregen. Dieser Beitrag hat zum Ziel, einen Überblick darüber zu geben, welche Privacy Nudges es im edukativen Bereich gibt und wie diese mit verschiedenen Lerntheorien in Einklang gebracht werden können. Der Text soll Forschern und Praktikern eine Orientierung geben, selbst edukative Privacy Nudges zu gestalten und endet mit einem Fallbeispiel, das aufzeigt wie einfache Gestaltungsänderungen Individuen dazu anregen können, sich privatheitsfreundlicher zu verhalten und sorgsamer mit ihren privaten Daten umzugehen.

In the realm of smart services, smart personal assistants (SPAs) have become a popular medium for value co-creation between service providers and users. The market success of SPAs is largely based on their innovative material properties, such as natural language user interfaces, machine-learning-powered request handling and service provision, and anthropomorphism. In different combinations, these properties offer users entirely new ways to intuitively and interactively achieve their goals and, thus, co-create value with service providers. But how does the nature of the SPA shape value co-creation processes? In this paper, we look through a functional affordances lens to theorize about the effects of different types of SPAs (i.e., with different combinations of material properties) on users' value co-creation processes. Specifically, we collected SPAs from research and practice by reviewing scientific literature and web resources, developed a taxonomy of SPAs' material properties, and performed a cluster analysis to group SPAs of a similar nature. We then derived 2 general and 11 cluster-specific propositions on how different material properties of SPAs can yield different affordances for value co-creation. With our work, we point out that smart services require researchers and practitioners to fundamentally rethink value co-creation as well as revise affordances theory to address the dynamic nature of smart technology as a service counterpart.

Gathering labeled data to train well-performing machine learning models is one of the critical challenges in many applications. Active learning aims at reducing the labeling costs by an efficient and effective allocation of costly labeling resources. In this article, we propose a decision-theoretic selection strategy that (1) directly optimizes the gain in misclassification error, and (2) uses a Bayesian approach by introducing a conjugate prior distribution to determine the class posterior to deal with uncertainties. By reformulating existing selection strategies within our proposed model, we can explain which aspects are not covered in current state-of-the-art and why this leads to the superior performance of our approach. Extensive experiments on a large variety of datasets and different kernels validate our claims.

Designing novel technologies provide challenges to developers. To support developers in designing these technologies, design knowledge must be codified and made applicable for the future. In systems development, design patterns provide proven solutions to solving recurring problems. They contain templates for describing design information, often in tabular form, and are established tools for making complex knowledge accessible and applicable. Design patterns play a critical role in both practice and research in finding potential solutions. For researchers, patterns can provide a method for codifying design knowledge for future research. For practitioners, design patterns provide established solutions to recurring problems. By applying them in a particular context, the pattern represents elements of both the problem-space and the solution-space, providing an opportunity to bridge the gap between the two spaces. Due to the abstraction of design patterns, they can be used for different application scenarios. The preparation of the design knowledge in the design pattern is a critical step to support the user in the best possible way, that determines the usefulness of the pattern.

Based on insights from an engineering design project conducted by Airbus and Local Motors, we describe how companies can leverage hybrid working by interlinking external crowds and internal employees, to increase the agility, quality and speed of product development. We identify the benefits and risks of hybrid working and describe the different ways of interlinking external crowds and internal employees. Finally, we provide recommendations for company executives who want to explore the use of hybrid working.

Bürgerbeteiligung war und ist wichtig – insbesondere in Zeiten von Covid-19. Dabei bedarf es einer sinnvollen Kombination und einer guten Verzahnung von digitalen und analogen Angeboten, wobei insbesondere im Kontext von Covid-19 die Frage bezüglich digitaler Bürgerbeteiligung im Raum steht: Wenn nicht jetzt, wann dann? Wir sprechen uns für Formen digitaler Bürgerbeteiligung aus, die bestehende Formen nicht ersetzen, sondern synergetisch ergänzen. Um dies zu tun, zeigen wir in diesem Beitrag auf, wie das Konzept des Government-as-a-Platform hierbei zu verstehen ist und helfen kann. Außerdem beschreiben wir Konzeption, Entwicklung und Integration einer digitalen Bürgerbeteiligungsplattform, die sich unter anderem durch die Verzahnung von Top-down- und Bottom-up-Elementen wie auch durch Transparenz der Plattform-Prozesse auszeichnet. Bürger*innen werden dabei als Expert*innen ihres Alltags gesehen und dazu empowert, durch eigene Projektvorschläge ihre Stadt proaktiv mitzugestalten.

Contemporary research focuses on examining trustworthy AI but neglects to consider trust transfer processes, proposing that users’ established trust in a familiar source (e.g., a technology or person) may transfer to a novel target. We argue that such trust transfer processes also occur in the case of novel AI-capable technologies, as they are the result of the convergence of AI with one or more base technologies. We develop a model with a focus on multi-source trust transfer while including the theoretical framework of trust duality (i.e., trust in providers and trust in technologies) to advance our understanding about trust transfer. A survey among 432 participants confirms that users transfer their trust from known technologies and providers (i.e., vehicle and AI technology) to AI-capable technologies and their providers. The study contributes by providing a novel theoretical perspective on establishing trustworthy AI by validating the importance of the duality of trust.

The annual number of publications at scientific venues, for example, conferences and journals, is growing quickly. Hence, even for researchers it becomes harder and harder to keep track of research topics and their progress. In this task, researchers can be supported by automated publication analysis. Yet, many such methods result in uninterpretable, purely numerical representations. As an attempt to support human analysts, we present topic space trajectories, a structure that allows for the comprehensible tracking of research topics. We demonstrate how these trajectories can be interpreted based on eight different analysis approaches. To obtain comprehensible results, we employ non-negative matrix factorization as well as suitable visualization techniques. We show the applicability of our approach on a publication corpus spanning 50 years of machine learning research from 32 publication venues. In addition to a thorough introduction of our method, our focus is on an extensive analysis of the results we achieved. Our novel analysis method may be employed for paper classification, for the prediction of future research topics, and for the recommendation of fitting conferences and journals for submitting unpublished work. An advantage in these applications over previous methods lies in the good interpretability of the results obtained through our methods.
Topological Indoor Mapping through WiFi Signals. Schaefermeier, Bastian; Stumme, Gerd; Hanika, Tom. 2021.

- [ BibSonomy-Post ]
The ubiquitous presence of WiFi access points and mobile devices capable of measuring WiFi signal strengths allow for real-world applications in indoor localization and mapping. In particular, no additional infrastructure is required. Previous approaches in this field were, however, often hindered by problems such as effortful map-building processes, changing environments and hardware differences. We tackle these problems focussing on topological maps. These represent discrete locations, such as rooms, and their relations, e.g., distances and transition frequencies. In our unsupervised method, we employ WiFi signal strength distributions, dimension reduction and clustering. It can be used in settings where users carry mobile devices and follow their normal routine. We aim for applications in short-lived indoor events such as conferences.

As more and more business processes are based on IT services the high availability of these processes is dependent on the IT-Support. Thus, making the IT-Support a critical success factor of companies. This paper presents how this department can be supported by providing the staff with domain-specific and high-quality solution material to help employees faster when errors occur. The solution material is based on previously solved tickets because these contain precise domain-specific solutions narrowed down to e.g., specific versions and configurations of hard-/software used in the company. To retrieve the solution material ontologies are used that contain the domain-specific vocabulary needed. Because not all previously solved tickets contain high-quality solution material that helps the staff to fix issues the designed IT-Support system separates lowfrom high-quality solution material. This paper presents (a) theory- and practicalmotivated design requirements that describe the need for automatically retrieved solution material, (b) develops two major design principles to retrieve domainspecific and high-quality solution material, and (c) evaluates the instantiations of them as a prototype with organic real-world data. The results show that previously solved tickets of a company can be pre-processed and retrieved to ITSupport staff based on their current queries.

Voice assistants’ increasingly nuanced and natural communication bears new opportunities for user experiences and task automation, while challenging existing patterns of human-computer interaction. A fragmented research field, as well as constant technological advancements, impede a common apprehension of prevalent design features of voice-based interfaces. As part of this study, 86 papers across domains are systematically identified and analysed to arrive at a common understanding of voice assistants. The review highlights perceptual differences to other human-computer interfaces and points out relevant auditory cues. Key findings regarding those cues’ impact on user perception and behaviour are discussed along with the three design strategies 1) personification, 2) individualization and 3) contextualization. Avenues for future research are lastly deducted. Our results provide relevant opportunities to researchers and designers alike to advance the design and deployment of voice assistants.

This work considers (deep) artiﬁcial feed-forward neural networks as parametric approximators in optimal control of discrete-time switched linear systems with controlled switching. The proposed approach is based on approximate dynamic programming and allows the fast computation of (sub-)optimal discrete and continuous control inputs, either by approximating the optimal cost-to-go functions or by approximating the optimal discrete and continuous input policies. An important property of the approach is the satisfaction of polytopic state and input constraints, which is crucial for ensuring safety, as required in many control applications. A numeric example is provided for illustration and evaluation of the approaches.

In recent years, using game concepts for educational purposes in digital environments has become continually more popular and relevant. Games can be used to motivate and engage users in regular system use and, in the end, support learners in achieving better learning outcomes. In this context, different kinds of game concepts exist, such as gamification or serious games, each with a different perspective and usefulness in digital learning environments. Because developing and using with game concepts in digital learning environments has recently become more important, and developing them is still not fully established, questions arise about future research directions involving games in digital learning. Therefore, this study aims to identify the state of the field and determine what is relevant when using game concepts in digital learning. To achieve this goal, we present the results of a bibliometric analysis considering more than 10,000 articles between 2000 and 2019 and summarize them to develop a research agenda. This agenda supports researchers and practitioners in identifying avenues for future research. We contribute to theory by providing a detailed understanding of the relevance of game concepts in digital learning. We propose a research agenda to assist researchers in planning future approaches with and about gamification concepts in digital learning. Practical implications are proposed by demonstrating what should be considered when using game concepts in learning environments.

Gamification refers to the use of game-like elements in non-entertainment contexts to make activities more engaging and enjoyable to improve utilitarian outcomes. The gamification literature and the use of gamification in practice suggest that gamification can be a useful tool to support behavioral and psychological changes. Recent developments show that there is potential for new waves of gamification research. Therefore, we conducted a workshop at the International Conference on Wirtschaftsinformatik (WI) 2021 to discuss the future of gamification with interested scholars. The discussion with 25 gamification experts led to a research agenda that supports the need for adaptive and personalized gamification designs. Together with the experts, we identify three clusters for future research: 1) the personalization of gamification concepts, 2) theories and concepts for gamified human-computer interaction, and 3) the “dark side” of gamification (e.g., addiction). We also address what the gamification concept means. Aligned with the three clusters, we provide valuable starting points for future research inquiries to help researchers better understand the nature of gamification. We also discuss the capabilities and limits of gamification.

Künstliche Intelligenz durchdringt immer stärker verschiedene Lebensbereiche und macht auch vor der beruflichen Bildung nicht halt. In diesem Zusammenhang gibt es derzeit vielfältige Diskussionen zur Rolle der menschlichen Intelligenz in zukünftigen Arbeitsprozessen und damit verknüpft Fragen zur Auswirkung auf die Aus- und Weiterbildung von Arbeitskräften. Ziel dieses Beitrags ist es darzulegen, warum in den kommenden Jahrzehnten die effektive Kombination der komplementären Stärken von menschlicher und künstlicher Intelligenz im Sinne des Hybrid Intelligence (HI)-Gedankens im Vordergrund stehen wird. Anschließend werden Potentiale und Grenzen von HI im Kontext der beruflichen Aus- und Weiterbildung mit besonderem Fokus auf die Individualisierung von Lehr-/Lernprozessen diskutiert.
Vibrotaktile Codierung von Standardfunktionen in einer Menüführung zur Verbesserung der Interaktion mit Touchscreens. Stein, T. In Vol. 2 of Schriftenreihe Mensch-Maschine-Systemtechnik. Kassel University Press, Kassel, 2021.

Den taktilen Sinneskanal zu nutzen, um Informationen an den Menschen zu übermitteln und somit den visuellen und auditiven Kanal zu entlasten, wurde bereits in verschiedenen Anwendungen und Szenarien analysiert. Bisher wurden hierfür zwischengeschaltete Geräte, beispielsweise ein Gurt, genutzt oder die Rückmeldung erfolgte an nicht-interagierenden Körperteilen. Bei Touchscreens erscheint allerdings eine Rückmeldung an den interagierenden Finger des Nutzers sinnvoll. Hierbei stellt sich die Frage, ob auch komplexe, inhaltliche Informationen über den taktilen Sinneskanal an den Nutzer weitergegeben und von diesem eindeutig erkannt werden können. Im Rahmen diese Arbeit wird daher die Möglichkeit der vibrotaktilen Informationscodierung mittels sogenannter Tactons untersucht. Tactons sind Vibrationsmuster, welche durch Modifikation ihrer Parameter, wie z. B. Frequenz und Amplitude, Informationen codieren können. Gerade für häufig vorkommende Funktionen einer Menüführung auf Touchscreens ist es sinnvoll, eindeutig zu identifizierende Tactons zu entwerfen. Durch den Vorschlag eines Tacton-Sets für solche Standardfunktionen leistet diese Arbeit einen Beitrag zur Standardisierung vibrotaktiler Informationsweitergabe. Zudem werden aus den Erkenntnissen der durchgeführten Studien übertragbare Empfehlungen bezüglich der Gestaltung von Tactons abgeleitet. Hierfür wurden sieben aufeinander aufbauende Forschungsfragen formuliert, für deren Beantwortung jeweils eine empirische Studie konzipiert, durchgeführt und ausgewertet wurde. Insgesamt 544 Personen im Alter von 15 bis 82 Jahren nahmen an diesen Evaluationen teil, sodass die Erkenntnisse der vorliegenden Arbeit auf einer fundierten Datengrundlage beruhen. Zunächst wurden Grundlagenexperimente bezüglich der taktilen Wahrnehmung des Menschen durchgeführt. Hierauf aufbauend wurden Möglichkeiten der vibrotaktilen Informationscodierung geprüft und ein solches Tacton-Set für Standardfunktionen erarbeitet und evaluiert. Dieses Tacton-Set kann in allen Anwendungen genutzt werden, in denen auf einem Touchscreen eine Menüführung verankert ist, die sich der untersuchten Standardfunktionen bedient und im Besonderen, wenn der visuelle und/oder auditive Fokus des Nutzers auf einer anderen Aufgabe liegt. Ein Einsatz des Tacton-Sets ist hierbei sowohl bei stationären als auch mobilen Endgeräten denkbar. Die aus den einzelnen Studien abgeleiteten, allgemeinen Empfehlungen für die Gestaltung von Tactons sind darüber hinaus auf unterschiedliche Anwendungskontexte übertragbar.

Tactons sind taktile Nachrichten, die dem Nutzer Informationen über den haptischen Sinneskanal übermitteln, und können beispielsweise bei der Interaktion mit Touchscreens von Nutzen sein. In dieser Studie wird die systematische Erarbeitung eines Tacton-Sets für Standardfunktionen einer Menüführung (im Einzelnen die Funktionen Beenden, Bestätigen, Hauptmenü, Hilfe, Korrektur, Lauter, Leiser sowie Zurück) vorgestellt. Neben existierenden Erkenntnissen aus der Literatur wurden bei der Gestaltung des Tacton-Sets ebenfalls die Ergebnisse einer Gruppenbefragung berücksichtigt, in der die Teilnehmer Ideen zur konkreten Ausgestaltung der Tactons äußern konnten. Das zunächst entstandene Tacton-Set wurde unter drei standardisierten Versuchsbedingungen von 54 Probanden evaluiert und lieferte eine Gesamterkennungsrate von 0,70 ± 0,19. Die Ergebnisse der einzelnen Tactons wurden analysiert und Verbesserungen hinsichtlich deren Gestaltung umgesetzt. Anschließend wurde das weiterentwickelte Tacton-Set unter den gleichen Versuchsbedingungen wie zuvor erneut von 39 Probanden evaluiert. Die resultierende Gesamterkennungsrate verbesserte sich signifikant auf 0,79 ± 0,18. Praktische Relevanz In alltäglichen Umgebungen mit zunehmender Informationsdichte wird die Übermittlung von Informationen über den haptischen Sinneskanal immer wichtiger. Diese Studie beinhaltet wichtige Erkenntnisse für die Gestaltung und schrittweise Verbesserung von Tactons im Allgemeinen und liefert einen Vorschlag für die konkrete Umsetzung eines Tacton-Sets für genannte Standardfunktionen. Es wird zudem deutlich, dass weitere Forschung nötig ist, um den Einsatz von Tactons zu etablieren.

Graphs can have different properties that lead to several graph types and may allow for a varying representation of diverse information. In order to clarify the modeling power of graphs, we introduce a partial order on the most common graph types based on an expressivity relation. The expressivity relation quantifies how many properties a graph type can encode compared to another type. Additionally, we show that all attributed graph types are equally expressive and have the same modeling power.

Argumentation is an omnipresent foundation of our daily communication and thinking. The ability to form convincing arguments is not only the fundament for persuading an audience of novel ideas but also plays a major role in strategic decision-making, negotiation, and productive civil discourse. However, students often struggle to develop argumentation skills due to a lack of individual and instant feedback in their learning journey, since providing feedback on the individual argumentation skills of learners is very time consuming and not scalable if conducted manually by educators. Following a design science research approach, we propose a new class of argumentation learning systems that provide students with individual and ongoing tutoring to support them in learning how to argue. We build our socio-technical design on a combination of user-centered design principles, a conceptualization of argumentation structures in student-written text, and Natural Language Processing and Machine Learning classifiers to provide individual feedback. To investigate if the new system class of AI-based argumentation tutoring systems helps students to improve their argumentation skills, we evaluated the novel artifact class in two empirical studies in comparison to traditional argumentation learning systems. In a laboratory experiment (study 1), as well as in a field experiment in a large-scale lecture over three months (study 2), we found that AI-based argumentation tutoring systems based on our design principles, argumentation schemes, and algorithms improve the short- and long-term argumentation skills of students significantly compared to the traditional argumentation learning approaches.

Techniques from Natural-Language-Processing offer the opportunities to design new dialog-based forms of human-computer interaction as well as to analyze the argumentation quality of texts. This can be leveraged to provide students with adaptive tutoring when doing a persuasive writing exercise. To test if individual tutoring for students' argumentation will help them to write more convincing texts, we developed ArgueTutor, a conversational agent that tutors students with adaptive argumentation feedback in their learning journey. We compared ArgueTutor with 55 students to a traditional writing tool. We found students using ArgueTutor wrote more convincing texts with a better quality of argumentation compared to the ones using the alternative approach. The measured level of enjoyment and ease of use provides promising results to use our tool in traditional learning settings. Our results indicate that dialog-based learning applications combined with NLP text feedback have a beneficial use to foster better writing skills of students.

We present an annotation approach to capturing emotional and cognitive empathy in student-written peer reviews on business models in German. We propose an annotation scheme that allows us to model emotional and cognitive empathy scores based on three types of review components. Also, we conducted an annotation study with three annotators based on 92 student essays to evaluate our annotation scheme. The obtained inter-rater agreement of alpha=0.79 for the components and the multi-pi=0.41 for the empathy scores indicate that the proposed annotation scheme successfully guides annotators to a substantial to moderate agreement. Moreover, we trained predictive models to detect the annotated empathy structures and embedded them in an adaptive writing support system for students to receive individual empathy feedback independent of an instructor, time, and location. We evaluated our tool in a peer learning exercise with 58 students and found promising results for perceived empathy skill learning, perceived feedback accuracy, and intention to use. Finally, we present our freely available corpus of 500 empathy-annotated, student-written peer reviews on business models and our annotation guidelines to encourage future research on the design and development of empathy support systems.

Educational process mining (EPM) offers new possibilities to discover, monitor, improve, or predict students’ learning processes using data about their learning activities captured in technology-mediated information systems (IS). Although EPM has recently attracted considerable research interest, there is still limited shared knowledge about the distinctive design characteristics of EPM from an integrative perspective. To address this gap, we conducted a systematic literature review to identify EPM characteristics. Building on a technology-mediated learning perspective, we develop a taxonomy that classifies EPM characteristics into four major categories (i.e., purpose, user, input, analysis). We evaluate and refine our taxonomy with ten domain experts, identified three clusters in the reviewed literature, and derived six archetypes of EPM scenarios based on our categorization. Finally, we formulate a novel research agenda to guide researchers in systematizing and synthesizing research on different technological embeddings of EPM in a students’ learning process.

Empathy is an elementary skill for daily interactions and for professional communication, agile teamwork and successful leadership and thus elementary for educational curricula. However, educational organizations face difficulties in providing the boundary conditions necessary for their students to develop empathy skills due to the lack of individual support in traditional large-scale and growing distance-learning scenarios. Drawing on cognitive dissonance theory, we propose an adaptive empathy learning tool that helps students develop their ability to react to other people's observed experiences through individual feedback in large-scale or distance learning scenarios. Based on a design science research project, we propose a set of design principles and instantiate and evaluate them with our prototype Eva in an online experiment with 65 students. The findings suggest that an adaptive empathy learning tool that follows our design principles is a promising approach to individually support students in their ability to react to other people's observed abilities in traditional learning scenarios.

‘Panel reports’ reflect a particular category of submissions that can be made to the Communications of the Association for Information Systems (CAIS). As stated online, panel reports differ from traditional research papers in that “CAIS is open to publishing reports of panels, debates, symposia, workshops and similar events. Such reports have to clearly position the matter of discussion at the event, highlight the relevance of event and topic and outline the different views on the topic that emanated at the events.” (https://aisel.aisnet.org/cais/panel_reports.pdf). While this definition has persisted for some time and still holds true, it leaves room for interpretation what constitutes a contribution and how one knows that a particular paper has made enough of one. The purpose of this editorial is to provide interpretation and elaboration of these principles based on our collective experience with such reports.

In August 2011 the Wall Street Journal published an essay by Netscape co-founder Marc Andreessen titled “Why software is eating the world”. He argues that “more and more major businesses and industries are being run on software and delivered as online services—from movies to agriculture to national defense. Many of the winners are Silicon Valley-style entrepreneurial technology companies that are invading and overturning established industry structures. […] Companies in every industry need to assume that a software revolution is coming.” (Andreessen 2011). By pointing at examples in various industries from automotive and banking to defense, healthcare, music, retailing, and telecommunications, he illustrates the transformational power of information technology (IT) and software in particular. The discussion is not new and dates back to the early 2000s. For example, Power and Jerjian (2001, p. 99) mention for Heathrow airport that “software is the thing that runs the airport” and in a biological analogy they consider software to be the nervous system. Meanwhile, the large “big tech” software companies (e.g., GAFAM, BATX) have impressively confirmed this development: their digital platforms have spread over many industries with an impact on processes (e.g., interaction and transaction), on products (e.g., app stores and services) as well as on business models (e.g., streaming and as-a-service models). The recent tech-portmanteaus (e.g., Fintech, Insurtech, Regtech) also reflect the attitude of these startup businesses, which perceive themselves rather as IT (tech) companies than as representatives of the industry they are aiming to transform (Meijer and Kapoor 2014). In the same vein, the high valuation of Tesla Motors since early 2020 spurred an intense debate of whether the company is in the automotive or the tech business (e.g., Klebnikov 2020). Obviously, these developments have numerous implications for the field of IT management, which were discussed during a panel at the 82nd Annual German Business Researcher Conference on March 18, 2020. The panel builds on prior discussions regarding the impact of digitalization on IT management. For example, a BISE discussion section in 2017 addressed the implications of the broad trend of digitalization for the field of Business Information Systems Engineering and pointed out new topics, such as digital innovation and transformation, which complement existing competencies (e.g., in modeling and managing enterprise IT). The discussion revealed strong arguments for the strategic role of IT and that business and IT departments as well as academia and practice need to collaborate more closely (Legner et al. 2017). While these statements adopted a rather broad perspective, another discussion section focused on “the impact of digitalization on the IT department” (Urbach et al. 2019). It mentioned important and intricate challenges: On the one hand, IT departments need to move closer to the business units and, on the other hand, they need to constantly update their technological skills in an environment with a high pace of technological innovation. In a world “eaten by software” these developments are equally prevalent and lead to the question how businesses address these challenges, in particular, how they assess the dominant role of software, how activities in managing the software lifecycle should be organized, and what the implications are for the BISE community.

When using digital technologies, various data traces are left behind for collection, storage and analysis. Innovative solutions for information systems are needed that mitigate privacy risks and foster information privacy. One mechanism to achieve this is using privacy nudges. Nudges are a concept from behavioral eco-nomics to influence individual’s decisions. However, many nudges show low or at least less effects than choice architects hope for and expect. Therefore, this de-sign science research (DSR) project focusses on developing evidence-based de-sign principles for privacy nudges to improve their effectiveness and pave the way for more privacy sensitive IT systems. In this context, we adopt a DSR ap-proach from Vaishnavi & Kuechler. From a theoretical perspective, we are con-tributing to the discussion of what drives privacy sensitive behavior. We extend generic nudge design models, making them applicable in the context of data dis-closure. For practitioners, we provide guidance on how to design and implement effective privacy nudges in the user interface of digital work systems.

Seit Jahrzehnten wird die geschlechtliche Verteilung von Studierenden in MINT bzw. der Informatik aus unterschiedlichen Perspektiven in den Blick genommen. Aus Sicht geschlechtertheoretischer Forschungen werden dafür unter anderem geschlechtliche Codierungen der Fächer gesehen, in denen sich alltägliches Geschlechterwissen und strukturelle Ungleichheiten manifestieren. In Bildern und Annahmen, die Schüler*innen und Studierende über die jeweiligen Fächer haben, werden diese vergeschlechtlichten Codierungen sichtbar. Der Beitrag fasst Ergebnisse ausgewählter Literatur zu Bildern von Informatik zusammen. Sie zeigen, wie die Befragten Informatik als männliches, weißes und westliches Fach konstruieren, welches Zugangs- und Aufstiegsmöglichkeiten mindestens einschränkt und ‚das Andere‘, also beispielsweise Frauen/Weiblichkeit, alles nicht-westliche, nicht-weiße – bzw. was diesen Begriffen zugeschrieben wird – abwertet. Beiträge zu Informatikbildern laufen jedoch Gefahr, bestehende Bilder zu reproduzieren. Deshalb werden in der untersuchten Literatur Leerstellen und Perspektiven aufgezeigt, die zu einer intersektionalen, reflektierten Forschung über Informatik(bilder) beitragen können.

We propose an algorithm for learning the Horn envelope of an arbitrary domain using an expert, or an oracle, capable of answering certain types of queries about this domain. Attribute exploration from formal concept analysis is a procedure that solves this problem, but the number of queries it may ask is exponential in the size of the resulting Horn formula in the worst case. We recall a well-known polynomial-time algorithm for learning Horn formulas with membership and equivalence queries and modify it to obtain a polynomial-time probably approximately correct algorithm for learning the Horn envelope of an arbitrary domain.
Which Motivations Boost Idea Quality? Exploring the Impact of Customers’ Motives for Participating in Virtual Ideas Communities on Ideation Outcome. Bretschneider, Ulrich. In European Conference on Information Systems (ECIS). Marrakesch, Marokko, 2020.

For practice it is important to leverage ideas of high quality from Virtual Ideas Communities (VIC). Therefore, firms that run such VIC have a strong interest in understanding which factors impact customers’ ideation outcome. This research investigates the influence of customers’ motivation factors for developing ideas on the quality of their ideas. So far, empirical studies that provide evidence on this association are neglected, although these insights would be highly beneficial for firms in their role as operator of VIC. Knowing the factors that have a positive influence will provide valuable insights into how to design effective incentive strategies that attract corresponding customer motivations and, in turn, will lead to higher levels of idea quality. In this research-in-progress paper we build a theoretical model explaining which of customers‘ motives for developing ideas have a positive impact on their ideation outcome.

Advances in smart home technological innovation over the years has seen an increase in consumer interests. However, research contexts for smart homes tend to skew towards “traditional”living and housing situations. Through my Ph.D. research, I raise awareness of the need to consider other user contexts and living situations. I do this by exploring opportunities for smart home innovation with elderly women who live alone. I work with the elderly women to understand their values, needs, and collaboratively create new smart home devices. The outcome of my research would be smart home devices that support the lives and contexts of elderly women living alone.

Künstliche intelligente (KI)-Systeme erfreuen sich immer größerer Beliebtheit. Im Alltag erleben wir KI beispielsweise durch smarte persönliche Assistenten (SPAs), welche von Amazon, Google und Co. angeboten werden. Zwar haben diese KI-Systeme große Nutzungspotenziale, gleichzeitig gehen damit aber auch erhebliche Risiken einher, beispielsweise datenschutzrechtliche. Doch wie lassen sich diese Spannungsfelder auflösen? Interdisziplinäre Gestaltungsmuster im Systementwicklungsprozess können eine Lösung darstellen, welche nachfolgend mit Handlungsimplikationen für gesellschaftlich wünschenswerte „KI made in Germany“ skizziert wird.

Im Rahmen des DFG-geförderten Projekts AnEkA „Anforderungs- und Entwurfsmuster zur rechtsverträglichen und qualitätszentrierten Gestaltung kontextsensitiver Applikationen“ wurden Anforderungs- und Entwurfsmuster für die Gestaltung rechtsverträglicher, aber gleichermaßen qualitätszentrierter smarter persönlicher Assistenten erstellt. Neben einem umfangreichen Musterkatalog hat das Projektteam ein Vorgehen für die Erstellung von Entwurfsmustern erarbeitet. Die Handlungsbroschüre soll zunächst eine Einführung in die Thematik der rechtsverträglichen und qualitätszentrierten Entwicklung geben und das Potential des Einsatzes von Anforderungs- und Entwurfsmustern aufzeigen. Darauf aufbauend werden das methodische Vorgehen, wie Muster zu erstellen sind, sowie die im Projekt erstellten Anforderungs- und Entwurfsmuster anhand von einigen Beispielen inhaltlich vorgestellt. Abschließend werden Handlungsempfehlungen für die Erstellung und den Einsatz von Anforderungs- und Entwurfsmustern gegeben. Im Anhang werden alle im Forschungsprojekt AnEkA erarbeiteten Anforderungs- und Entwurfsmuster zur weiteren Nutzung zur Verfügung gestellt.

In der Entwicklung informationstechnischer Systeme entstehen oft Zielkonflikte, die durch Gestaltung der Systeme aufgelöst werden müssen. Hierfür fehlt es Entwicklern, insbesondere bei Konflikten zwischen Rechtsverträglichkeit und Dienstleistungsqualität, oft an dem notwendigen Wissen und der erforderlichen Gestaltungserfahrung. Hier können Entwurfsmuster weiterhelfen. Der Beitrag stellt am Beispiel Smarter Persönlicher Assistenten einen Ansatz vor, in dem Entwurfsmuster interdisziplinäres Gestaltungswissen zusammenführen, geht auf die Besonderheiten des Gestaltungswissens der beiden Disziplinen ein und stellt ein beispielhaftes Entwurfsmuster vor.

In Zeiten der Digitalisierung nimmt Informationstechnologie eine Schlüsselrolle im Modernisierungsprozess von Unternehmen ein. Zugleich bringt die Softwareeinführung das Risiko mit sich, den intendierten Nutzen nicht zu realisieren. Durch eine Dienstleistungssystem-Perspektive erscheint die Einbindung der Nutzer in die Softwareeinführung ein vielversprechender Ansatz. Das Ziel des Projektes ExTEND – Engineering von Dienstleistungssystemen für nutzergenerierte Dienstleistungen ist es daher, Nutzer in die Softwareeinführung nach dem Leitbild „Dienstleistungen von Nutzern für Nutzer“ zu befähigen, aktiv einen Beitrag zu der Gestaltung der Arbeitsumgebung zu leisten. Hieraus resultieren IT-gestützte Servicebausteine, in denen Nutzer sich gegenseitige Hilfestellungen geben und Handlungsalternativen in der Softwareeinführung aufzeigen. Durch ein Pilotierungsvorgehen werden die Servicebausteine in drei Anwendungsfeldern entwickelt und pilotiert. Hieraus resultiert evidenzbasiertes Gestaltungswissen für die Entwicklung von nutzergenerierten Dienstleistungen. Darüber hinaus wird ein Mehrebenenmodell für die Gestaltung von Dienstleistungssystemen vorgestellt, welches die Entwicklung von Dienstleistungssystemen unterstützt und über traditionelle Ansätze des Service Engineerings hinausgeht.

The curse of dimensionality is a phenomenon frequently observed in machine learning (ML) and knowledge discovery (KD). There is a large body of literature investigating its origin and impact, using methods from mathematics as well as from computer science. Among the mathematical insights into data dimensionality, there is an intimate link between the dimension curse and the phenomenon of measure concentration, which makes the former accessible to methods of geometric analysis. The present work provides a comprehensive study of the intrinsic geometry of a data set, based on Gromov's metric measure geometry and Pestov's axiomatic approach to intrinsic dimension. In detail, we define a concept of geometric data set and introduce a metric as well as a partial order on the set of isomorphism classes of such data sets. Based on these objects, we propose and investigate an axiomatic approach to the intrinsic dimension of geometric data sets and establish a concrete dimension function with the desired properties. Our mathematical model for data sets and their intrinsic dimension is computationally feasible and, moreover, adaptable to specific ML/KD-algorithms, as illustrated by various experiments.

Ein Prototyp eines omnidirektionalen Laufeingabegerätes wurde insbesondere hinsichtlich des Regelungskonzeptes auf Basis von Empfehlungen aus der Literatur optimiert. Der Beitrag stellt die relevanten Rahmenbedingungen des Einsatzes solcher Systeme vor und berichtet über die Ergebnisse einer vergleichenden Studie, die auf die Verbesserung der Nutzung, insbesondere bzgl. der Regelung der translatorischen und der rotatorischen Bewegungsrichtung, abzielt. Dabei wurden zwei neuentwickelte Regelungsvarianten der bestehenden Lösung des Herstellers gegenübergestellt. Die Effekte wurden mit gängigen Standardfragebögen sowie Befragungsinstrumenten zu anderen Laufeingabegeräten untersucht. Es konnte ein signifikanter Vorteil des neuen Regelungskonzeptes belegt werden.

Wind power forecasts of the expected wind feed-in for the next hours or days are necessary to integrate the generated volatile wind energy into power systems. Most forecasting models predict in some sense the best value, but they ignore the other possible outcomes which may arise because of forecasting uncertainties. Probabilistic forecasts, on the other hand, also predict a distribution of possible outcomes with their respective probabilities that specific power values will occur and therefore have higher information content. In this work, we address two problems that hinder the introduction of probabilistic forecasts in practice: (1) no measurement data are available for some wind farms and (2) the flexible aggregation of probabilistic forecasts for changing wind farm portfolios.

The success of innovative teaching/learning approaches aiming to foster problem solving in management education depends on useful and easy-to-use IT components in the learning process. However, the complexity of problem solving in self-regulated learning approaches may overwhelm the learner and can lead to unsatisfying learning outcomes. Research suggests the implementation of technology-enhanced scaffolds as a mechanism to guide the learners in their individual problem-solving process to enhance their learning outcomes. We present a theoretical model based on adaptive structuration theory and cognitive load theory that explains how technology-enhanced scaffolding contributes to learning outcomes. We test the model with a fully randomized between-subject experiment in a flipped classroom for management education focusing on individual problem solving. Our results show that technology-enhanced scaffolding contributes significantly to the management of cognitive load as well as to learning process satisfaction and problem-solving learning outcomes. Thereby, our paper provides new conceptual and empirically tested insights for a better understanding of technology-enhanced scaffolds and their design to assist problem solving and its respective effects in flipped classrooms for management education.

This paper investigates how Algorithmic Experience (AX) can be used as a conceptual tool to help make algorithms and experiences of them visible through systems design and how interactions might be designed in order to elicit conscious and critical examination. Can algorithmic systems be positioned as critical artifacts? If so, to what extent? The paper reflects on interactions between users and the Social Privilege Estimator– a social scoring system based on facial recognition and classification that was built as a critical design artifact in order to raise awareness of existing inequalities and adverse effects of facial recognition systems. We argue that critical design can and should be used for AX and human-algorithm interaction design in order to support algorithmic literacy and critical capacity of the users and we suggest some conceptual reframings of AX towards this goal.

Künstlich intelligente (KI) Systeme erfreuen sich immer größerer Beliebtheit. Insbesondere smarte persönliche Assistenten (SPAs) von Amazon, Google und vielen weiteren verzeichnen ein stetiges Marktwachstum. Den vielfältigen Potenzialen dieser KI-Systeme stehen jedoch auch zahlreiche Risiken gegenüber. Berichte von Datenpannen und -lecks häufen sich und haben bei Nutzern eine zunehmende Skepsis zur Folge, was zu einem gespaltenen Bild von KI in der Gesellschaft beiträgt. Diesem Problem stellt sich das Forschungsprojekt AnEkA mit einem interdisziplinären Gestaltungsansatz. Auf Basis von Rechts- und Qualitätszielen werden Anforderungen an rechtsverträgliche und qualitativ hochwertige SPAs abgeleitet. Zusätzlich werden Gestaltungsalternativen identifiziert, die diese Anforderungen unter Berücksichtigung möglicher Zielkonflikte umsetzen. Ergebnis des Projekts sind Entwurfsmuster, die Entwicklern von SPAs dabei helfen sollen, rechtsverträgliche und qualitativ hochwertige SPAs und KI-Systeme im Allgemeinen zu entwickeln. Dadurch soll das Alleinstellungsmerkmal einer „KI made in Germany`` entstehen, welche sowohl die Bedürfnisse von Nutzern berücksichtigt und sie ebenfalls bestmöglich vor Risiken der Systemnutzung schützt. Dieser Beitrag erläutert das interdisziplinäre Vorgehen anhand eines Szenarios zur Nutzung von SPAs.

Gamification has taken the world by storm. Regardless of where one stands on gamification, it can aptly be described as interesting but also galvanising and controversial. We are pleased to write a provocative editorial to kick off this special issue on gamification in the European Journal of Information Systems. Our position is that the information systems (IS) discipline has the opportunity to play an outsized role in navigating the discourse of gamification-an increasingly influential, interdisciplinary discourse in research and practice. We assert that active engagement in the gamification discourse is a compelling IS research opportunity, given the growing, globalised platform-based economy. Consequently, we frame our editorial with the knowledge we have gained as IS researchers who engage in gamification research in an effort to share what we have learned about artefacts and original theorisation with both IS and gamification scholars. We do so by proposing a pragmatic path forward for gamification and IS researchers who wish to contribute to these related discourses, both individually and in the form of the combined IS-gamification discourse. We propose a framework of three practices that we are confident can more systematically generate the key theoretical artefacts needed to generate native theory in the IS-gamification discourse and hence to improve the associated research and practice. Foundational to this framework is our paradigm, which advocates active engagement with IS-gamification research and practice, as bridged by a strong focus on design thinking and generating artefacts that are foundational to theory generation.

Im Rahmen des Projektes RadAR+ wurde eine Augmented-Reality-(AR)-Reiseassistenzanwendung für eine Datenbrille entwickelt und prototypisch umgesetzt, welche ein Routing für den öffentlichen Verkehr sowie eine AR-Fußgängernavigation vereint und dadurch eine vollständige Navigation vom Start- zum Zielort ermöglicht. Der Prototyp wurde in einem Echtweltszenario mit 37 Probanden vergleichend zur herkömmlichen Unterstützung evaluiert. Es konnte gezeigt werden, dass die Gebrauchstauglichkeit der AR-Reiseassistenzanwendung von den Probanden als "gut" bewertet wird. Des Weiteren ist feststellbar, dass keine signifikanten Unterschiede zwischen der subjektiv empfundenen Beanspruchung beim Prototyp und der herkömmlichen Unterstützung bestehen. Jedoch gab es eine signifikant geringere Schrittzahl bei der Gruppe, die das Reiseassistenzsystem nutzte.

The competitiveness of organizations and whole economies depends on how successfully they are able to cope with the digital transformation and new technological trends. In the area of digital work, crowdworking platforms emerged as intermediaries that support a new form of service delivery and work organization. Despite their increasing importance, there is only few data about key characteristics of such platforms such as number of employees or revenues. Furthermore, extant data often focusses only on a few platforms, mostly from the US. Based on results from a study about the 32 crowdworking platforms that have their headquarters or a physical location in Germany, we provide data that for the first time allows to draw conclusions for the “total population” of crowdworking platforms in a defined larger region (Germany as Europe’s largest and the world fourth largest economy). These results are valuable for various stakeholders from economy and politics, allowing them to make economic or political decisions on a more informed basis. Furthermore, we develop an evaluation framework that depicts the implications for these groups along the dimensions costs, flexibility, “humanity”, quality, and time: Crowdworking platforms on the one hand provide several opportunities: Individuals gain more flexibility, groups can benefit from additional contributors, organizations have the potential to process work faster and cheaper. On the other hand, this novel form of work organization also includes potential threats for all groups: Low payments and ‘tayloristic’ work, insufficient quality or irritation of internal employees. Based on 12 interviews with company representatives and crowdworkers, we evaluate implications of this novel form of work organization for society.

Car-to-Pedestrian (Car2P) communication has a huge potential for preventing potential accidents between pedestrians and vehicles by exchanging context information. Similar communication principles have been explored for Car-to-Car (C2C) communication since quite a while and are now being deployed as an additional safety mechanism. Unfortunately, Vulnerable Road Users (VRUs) such as pedestrians and bicyclists are not yet covered by these systems. Looking at pedestrians, we explore possibilities for the exchange of relevant safety mechanisms between pedestrians and cars making use of readily available communication capabilities of current LTE networks. Necessary activity and collision detection algorithms have to be run on the users’ smartphones in order to determine the criticality of the situation. In order to improve both the overall system latency and the energy efficiency of the smartphone applications, we suggest the use of Multi-access Edge Computing (MEC). We implemented the system to perform measurements on the smartphone side as well as extensive simulations on the networking side. Our results clearly show the advantages of our concept and the integrated MEC approach.

Designing socio-technical systems like IT-supported teaching-learning systems that motivate learners while at the same time stimulating knowledge transfer has become challenging. Teaching-learning techniques that consist of a social context that interacts with and is supported by information technologies are often bundled in a holistic design artifact. To explore a socio-technical design artifact, one must recognize that it consists of several sub-artifacts, each of which must have its own design approach. We introduce the research approach of designing and piloting the IT-supported teaching-learning concept, sensitized to the demand of distinguishing among several socio-technical sub-artifacts. We present the purpose of our design science research (DSR) journey and differentiate among several design artifacts, each of which make prescriptive knowledge contributions and, thus, represent diverse types of theory in information systems. The first artifact is a Peer Creation Process for enhancing knowledge transfer and documentation, which contributes to a nascent design theory. The second artifact is a User-Centered Process to gamify LMSs, which contributes to a theory of design and action. We describe the DSR journey that was part of the project StaySmart, the purpose of which was to design and evaluate a teaching-learning concept for knowledge workers. Teaching-learning artifacts usually have one purpose: to design and evaluate the learning experience. However, designing such artifacts requires identifying their sub-purposes, which leads to designing and evaluating several design artifacts, which we call teaching-learning techniques, so a holistic design artifact usually has several design artifacts. Therefore, the project makes distinct prescriptive knowledge contributions and has the potential to create distinct types of theory in information systems. Our case provides guidance in developing artifacts for a holistic design artifact and in understanding how such artifacts can be separated into sub-artifacts that have their own design science approaches.

Die Komplexität des öffentlichen Personenverkehrs nimmt durch die stetige Verdichtung und Verknüpfung unterschiedlicher Verkehrsmittel zu. Die daraus erwachsenden Anforderungen an die kognitive und physische Leistungsfähigkeit des Menschen beim Wechsel minutengenau getakteter Verkehrsmittel lassen besonders an hochbelasteten Knotenpunkten vermehrt kritische Situationen bei der Durchführung von Reiseketten entstehen, die alle Altersgruppen betreffen. Dies kann z. B. bei mangelnden Ortskenntnissen zur Informationsüberflutung und zur Orientierungslosigkeit von Reisenden führen. Im Projekt RadAR+ wurde ein persönliches Reiseassistenzsystem entwickelt, das Nutzerinnen und Nutzer bei Verkehrsmittelwechseln an komplexen Mobilitätsknoten unterstützt. Das Teilvorhaben zur Mensch-Technik-Interaktion beschäftigte sich dabei schwerpunktmäßig damit, dass die benötigten Informationen in ergonomisch angemessener Form zum richtigen Zeitpunkt und in der notwendigen Tiefe bereitgestellt werden. Das lernende Assistenzsystem verwaltet das erforderliche Umgebungswissen an Verkehrsknoten und stellt die navigationsrelevanten Daten in Echtzeit zur Verfügung. Ein adaptives Nutzermodell lernt die Mobilitätsanforderungen und Bedürfnisse des Nutzers. Auf dieser Basis werden bspw. Empfehlungen zur Gestaltung längerer Aufenthalte beim Umstieg entlang intermodaler Reiseketten berechnet. Für die individualisierte Mobilitätsplanung werden je nach persönlichen Bedürfnissen mobile Geräte, insbesondere Datenbrillen, verwendet. Auf diese Weise können auch komplexe Routeninformationen situationsgerecht vermittelt werden. Durch Visualisierung von Augmented-Reality-(AR)-Elementen in der Datenbrille wird der Nutzer bei der Navigation zum gewünschten Verkehrsmittel sowie bei der Abschätzung der dazu noch verfügbaren Zeit unterstützt. Hierbei werden auch ggf. vorliegende Abweichungen vom Normalfall mit Echtzeitdaten automatisch berücksichtigt. Die Entwicklung folgte einem iterativen benutzerorientierten Gestaltungsprozess, um die bedarfsgerechte Umsetzung und letztlich die Akzeptanz der Nutzer sicherzustellen. Konzepte und Teillösungen wurden unter Nutzerbeteiligung formativ evaluiert und die Ergebnisse in folgenden Entwicklungsiterationen aufgegriffen. Ein barrierearmer Technologie-Zugang wurde mit intuitiver Mensch-Maschine-Kommunikation (AR-, Sprach-User-Interfaces) erreicht. Abschließend wurde ein Demonstrator realisiert, der im Feld entlang einer intermodalen Reisekette in Frankfurt am Main summativ evaluiert wurde. Die Ergebnisse ermöglichen eine Reiseassistenz, die eine breite Bevölkerungsschicht bei der Orientierung im öffentlichen Personenverkehr unterstützt
Understanding User Preferences of Digital Privacy Nudges – A Best-Worst Scaling Approach. Schöbel, Sofia; Barev, Torben Jan; Janson, Andreas; Hupfeld, Felix; Leimeister, Jan Marco. In Hawaii International Conference on System Sciences (HICSS). 2020.

Digital nudging in privacy has become more important to protect users of information systems while working with privacy-related data. Nudging is about altering a user’s behavior without forbidding any options. Several approaches exist to “nudge” users to change their behavior. Regarding the usage of digital privacy nudges, research still has to understand the meaning and relevance of individual nudges better. Therefore, this paper compares the preferences of users for different digital nudges. To achieve this goal, it presents the results of a so-called best-worst scaling. This study contributes to theory by providing a better understanding of user preferences regarding design variations of digital nudges. We support practitioners by giving implications on how to design digital nudges in terms of user preferences.

Gamification is a well-known approach that refers to the use of elements to increase the motivation of information systems users. A remaining challenge in gamification is that no shared understanding of the meaning and classification of gamification elements currently exists. This impedes guidance concerning analysis and development of gamification concepts, and often results in non-effective gamification designs. The goal of our research is to consolidate current gamification research and rigorously develop a taxonomy, as well as to demonstrate how a systematic classification of gamification elements can provide guidance for the gamification of information systems and improve understanding of existing gamification concepts. To achieve our goal, we develop a taxonomic classification of gamification elements before evaluating this taxonomy using expert interviews. Furthermore, we provide evidence as to the taxonomy’s feasibility using two practical cases: First, we show how our taxonomy helps to analyse existing gamification concepts; second, we show how our taxonomy can be used for guiding the gamification of information systems. We enrich theory by introducing a novel taxonomy to better explain the characteristics of gamification elements, which will be valuable for both gamification analysis and design. This paper will help guide practitioners to select and combine gamification elements for their gamification concepts.

Interne Crowd Work gewinnt im Hinblick auf eine agilitätsfördernde Arbeitsorganisation immer mehr an Bedeutung. Das Empowerment der Mitarbeitenden kann dabei als ein zentraler Erfolgsfaktor angesehen werden. Um das Empowerment in interner Crowd Work zielgerichtet zu untersuchen und die Wahrnehmung aus Sicht der Mitarbeitenden sowie die Effekte auf Ebene der Gesamtorganisation zu verstehen und beschreiben zu können, analysieren wir die interne Crowd Work mit Hilfe einer literaturbasierten erweiterten Wirtschaftlichkeitsbetrachtung sowie empirisch anhand von sechs Fallstudien. Auf organisationaler Ebene stehen im Ergebnis dabei insbesondere die Themen Organisationskultur, abteilungsübergreifende Zusammenarbeit und die Gestaltung von Aufgaben und Projekten im Fokus. Auf individueller Ebene können vornehmlich die selbstbestimmte Wahl von Arbeitsaufgaben inkl. selbstorganisierter Arbeitsprozesse sowie neue Führungsansätze als wesentliche Stellschrauben identifiziert werden.

Comparing and ordering things is a basal ability of mankind for organizing its physical and social environment. While many hierarchical relationships can be derived from numerical measures like length or voltage, many others cannot appropriately be captured this way. We argue that the newly emerging field of data science up to now lacks engagement in developing analysis methods for such ordinal data. By the example of an already existing approach in this domain, Formal Concept Analysis, we will discuss its capabilities as a knowledge representation and argue – based on its philosophical foundations – why it is an important building block for socially acceptable IT design.

In this paper, we present a novel annotation approach to capture claims and premises of arguments and their relations in student-written persuasive peer reviews on business models in Ger-man language. We propose an annotation scheme based on annotation guidelines that allows to model claims and premises as well as support and attack relations for capturing the structure of argumentative discourse in student-written peer reviews. We conduct an annotation study with three annotators on 50 persuasive essays to evaluate our annotation scheme. The obtained inter-rater agreement of α = 0.57 for argument components and α = 0.49 for argumentative relations indicates that the proposed annotation scheme successfully guides annotators to moderate agreement. Finally, we present our freely available corpus of 1,000 persuasive student-written peer reviews on business models and our annotation guidelines to encourage future research on the design and development of argumentative writing support systems for students.

Recent advances in Natural Language Processing not only bear the opportunity to design new dialog-based forms of human-computer interaction but also to analyze the argumentation quality of texts. Both can be leveraged to provide students with individual and adaptive tutoring in their personal learning journey to develop argumentation skills. Therefore, we present the results of our design science research project on how to design an adaptive dialog-based tutoring system to help students to learn how to argue. Our results indicate the usefulness of an adaptive dialog-based tutoring system to support students individually, independent of a human instructor, time and place. In addition to providing our embedded software artifact, we document our evaluated design knowledge as a design theory. Thus, we provide the first step toward a nascent design theory for adaptive conversational tutoring systems to individual support metacognition skill education of students in traditional learning scenarios.

Die Digitalisierung führt zu neuen Anforderungen an Fähigkeiten und Kenntnissen, die Studierende in ihrem zukünftigen Berufsleben benötigen. Metakognitive Lernkompetenzen und Higher Order Thinking Skills werden dabei immer wichtiger, um Herausforderungen der Zukunft zu lösen. Eine Unterklasse dieser Fähigkeiten, die wesentlich zu Kommunikation, Kollaboration und Problemlösung beiträgt, ist die Fähigkeit, strukturiert und reflektierend zu argumentieren. Bildungseinrichtungen haben jedoch Schwierigkeiten, die für die Entwicklung dieser Fähigkeit notwendigen Rahmenbedingungen zu schaffen. In diesem Paper stellen wir unser Design Science Research Projekt vor, in dem wir ein Lerntool entwickeln, dass es ermöglicht, Studierende durch intelligentes Feedback beim Erlernen von Argumentation zu unterstützen. Wir präsentieren dazu acht Designprinzipien, abgeleitet aus aktueller Literatur und aus 21 Nutzerinterviews, sowie einen evaluierten Prototyen als eine Form der Instanziierung dieser Prinzipien. Ziel unseres Forschungsprojektes ist es, ein Lerntool zu entwickeln, das Studierenden hilft, ihre Argumentationsfähigkeit durch individuelles Feedback zu verbessern.

Today’s graduating students face ever-changing environments when they enter their job life. Educational institutions must therefore continuously develop their course structure and content in order to prepare their students to be future employees. A very important means for developing the courses is the students’ course evaluations. Due to financial and organizational restrictions, these course evaluations are usually carried out quantitatively and at the end of the semester. However, past research has shown that this kind of evaluation faces certain constraints such as low acceptance rates, only time-related insights and low-quality answers that do not really help the lecturer to improve the course. Drawing on social response theory, we propose that conversational agents as a formative course evaluation tool are able to address the mentioned problems by interactively engaging with students. Therefore, we propose a set of design principles and evaluate them with our prototype Eva.

Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. We hypothesize that these interfaces can interactively engage students to increase response quality of course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor response quality caused by inattention, survey fatigue or satisficing behavior. To test if conversational interfaces have a positive impact on the level of enjoyment and the response quality, we design an NLP-based conversational agent and deploy it in a field experiment with 127 students in our lecture and compare it with a web survey as a baseline. Our findings indicate that using conversational agents for evaluations are resulting in higher levels of response quality and level of enjoyment, and are therefore, a promising approach to increase the effectiveness of surveys in general.

There are gaps in understanding in and between those who design systems of AI/ ML, those who critique them, and those positioned between these discourses. This gap can be defined in multiple ways - e.g. methodological, epistemological, linguistic, or cultural. To bridge this gap requires a set of translations: the generation of a collaborative space and a new set of shared sensibilities that traverse disciplinary boundaries. This workshop aims to explore translations across multiple fields, and translations between theory and practice, as well as how interdisciplinary work could generate new operationalizable approaches. We define 'knowledge' as a social product (L. Code) which requires fair and broad epistemic cooperation in its generation, development, and dissemination. As a "marker for truth" (B. Williams) and therefore a basis for action, knowledge circulation sustains the systems of power which produce it in the first place (M. Foucault). Enabled by epistemic credence, authority or knowledge, epistemic power can be an important driver of, but also result from, other (e.g. economic, political) powers. To produce reliable output, our standards and methods should serve us all and exclude no-one. Critical theorists have long revealed failings of epistemic practices, resulting in the marginalization and exclusion of some types of knowledge. How can we cultivate more reflexive epistemic practices in the interdisciplinary research setting of FAT*? We frame this ideal as 'epistemic justice' (M. Geuskens), the positive of 'epistemic injustice', defined by M. Fricker as injustice that exists when people are wronged as a knower or as an epistemic subject. Epistemic justice is the proper use and allocation of epistemic power; the inclusion and balancing of all epistemic sources. As S. Jasanoff reminds us, any authoritative way of seeing must be legitimized in discourse and practice, showing that practices can be developed to value and engage with other viewpoints and possibly reshape our ways of knowing. Our workshop aims to address the following questions: how could critical theory or higher level critiques be translated into and anchored in ML/AI design practices - and vice versa? What kind of cartographies and methodologies are needed in order to identify issues that can act as the basis of collaborative research and design? How can we (un)learn our established ways of thinking for such collaborative work to take place? During the workshop, participants will create, share and explode prototypical workflows of designing, researching and critiquing algorithmic systems. We will identify moments in which translations and interdisciplinary interventions could or should happen in order to build actionable steps and methodological frameworks that advance epistemic justice and are conducive to future interdisciplinary collaboration.

Smart learning services offer customized learning solutions by systematically considering the context of the learner. However, it is still unclear how the value co-creation within smart learnings is affected by context considerations. Therefore, it is important to understand how the context can influence the value co-creation potential in smart learning services. To investigate how context shapes value co-creation smart learning services, we first conduct a systematic literature review to investigate context factors within learning processes. Afterwards, we develop a conceptual model to explain how context in smart learning systems can be used to enhance the co-creation potential in learning processes. Overall, we provide a better understanding of context considerations in service systems as a theoretical contribution of our conceptual investigation. Finally, we provide practical implications for educational service providers for designing smart learning services under the specific consideration of different contexts

Online education creates new opportunities for learners, which has led to sharply increasing enrollment in the last few years. Despite these benefits, past research shows that the lack of individual interaction with educators creates low learner engagement that leads to high attrition rates, which remains a major challenge in the field. Dynamically scaffolding conversational agents built into online video lectures promise to address this problem by individually interacting with learners, similar to educators’ scaffolding behavior. These agents are equipped with recent natural language processing capabilities, creating human-like conversations that help learners to be more engaged in the learning process. To test our hypothesis, we built a dynamically scaffolding conversational agent named Sara and compared it with an often-implemented static conversational agent built into two online video lectures. We deployed a lab experiment with 182 learners. The neurophysiological measurements revealed that Sara significantly improved learner engagement partly explained by differences in learners’ perceptions in the way they experienced the interaction. This study connects to already existing conversational agent studies in online education and highlights the importance of including dynamically scaffolding conversational agents in online video lectures to address the problem of low learner engagement in online education.

Despite a growing body of research about the design and use of Smart Personal Assistants such as Amazon’s Alexa or Google’s Assistant, little is known about their ability to help educators offering individual support in large-scale learning environments. Smart Personal Assistant ecosystems empower educators to develop their own agents without deep technological knowledge. The objective of this paper is to design and validate a method that helps educators to create Smart Personal Assistants as learning tutors. Using a design science research approach, we first gather requirements from students and educators as well as from information systems and education theory. Next, we create an alpha version of our method and evaluate it with a focus group before we instantiate our artifact in an everyday learning environment. The findings indicate that our method is able to empower educators to design Smart Personal Assistants that significantly improve students’ learning success.

Tomorrow’s organizations need employees who are able to deal with rapid changes and solve non-routine problems. Gaining problem-solving skills is considered the number-one skill for future employees to succeed professionally. Predominant learning theories agree that the most effective way to gain these skills is for everyone to receive individual support by their own private tutor. For educational institutions such as high schools and universities, this is often not possible due to financial and organizational restrictions. A new emerging class of information technology – specifically Smart Personal Assistants (e.g., Google’s Assistant or Amazon’s Alexa) – has the potential to address this problem by interacting with students in a manner comparable to human tutors because of its high degree of adaptability, interactivity and accessibility. Even though there exists a growing body of research about the design and use of Smart Personal Assistants for learning, empirical evidence of their ability to help students improve their problem-solving skills is still scarce. Grounded on technology-mediated learning theory, this study uses a mixed-method approach consisting of two field quasi-experiments and one post-experiment focus group discussion at a business high school and a vocational business school with a total of 90 students to measure the effect of using Smart Personal Assistants on acquiring problem-solving skills. The empirical results show that students in the experiment classes acquired significantly more problem-solving skills than those in the control group mainly explained by changes in their learning process. The findings provide empirical evidence for the importance of using new emerging Smart Personal Assistants on general skill development, and specifically on problem-solving skill development. Moreover, our work can guide educational institutions and educators in designing and implementing Smart Personal Assistants in their own learning environments.

The knowledge base related to user interaction with conversational agents (CAs) has grown dramatically but remains segregated. In this paper, we conduct a systematic literature review to investigate user interaction with CAs. We examined 107 papers published in outlets related to IS and HCI research. Then, we coded for design elements and user interaction outcomes, and isolated 7 significant determinants of these outcomes, as well as 42 themes with inconsistent evidence, providing grounds for future research. Building upon the insights from the analysis, we propose a research agenda to guide future research surrounding user interaction with CAs. Ultimately, we aim to contribute to the body of knowledge of IS and HCI in general and user interaction with CA in particular by indicating how developed a research field is regarding the number and content of the respective contributions. Furthermore, practitioners benefit from a structured overview related to CA design effects.

Smart Personal Assistants (SPA) fundamentally influence the way individuals perform tasks, use services and interact with organizations. They thus bear an immense economic and societal potential. However, a lack of trust - rooted in perceptions of uncertainty and risk - when interacting with intelligent computer agents can inhibit their adoption. In this paper, we conduct a systematic literature review to investigate the state of knowledge on trust in SPAs. Based on a concept-centric analysis of 50 papers, we derive three distinct research perspectives that constitute this nascent field: user interface-driven, interaction-driven, and explanation-driven trust in SPAs. Building on the results of our analysis, we develop a research agenda to spark and guide future research surrounding trust in SPAs. Ultimately, this paper intends to contribute to the body of knowledge of trust in artificial intelligence-based systems, specifically SPAs. It does so by proposing a novel framework mapping out their relationship.
Towards Developing Trust-Supporting Design Features for AI-Based Chatbots in Customer Service. Zierau, Naim; Hausch, Michael; Bruhin, Olivia; Söllner, Matthias. In International Conference on Information Systems (ICIS). 2020.

Chatbots are predicted to play a key role in customer service based on recent advances in the area of Artificial Intelligence (AI). However, a lack of user trust impedes the widespread adaption of AI-based chatbots. Still, there is a lack of systematically derived design knowledge concerning user trust in those agents. In this short paper, we report on the first steps of our design science research project on which design principles are relevant for building trust in chatbots. Based on trust literature and user interviews, we propose preliminary requirements and design principles for trust-enhancing design features for chatbots in customer service. Furthermore, we present a first instantiation of those principles. These insights will support researchers and practitioners to better understand how user trust in chatbots can be systematically built to increase adoption and usage.

In the last decade, the effects of interruptions through mobile notifications have been extensively researched in the field of Human-Computer Interaction. Breakpoints in tasks and activities, cognitive load, and personality traits have all been shown to correlate with individuals' interruptibility. However, concepts that explain interruptibility in a broader sense are needed to provide a holistic understanding of its characteristics. In this paper, we build upon the theory of social roles to conceptualize and investigate the correlation between individuals' private and work-related smartphone usage and their interruptibility. Through our preliminary study with four participants over 11 weeks, we found that application sequences on smartphones correlate with individuals' private and work roles. We observed that participants engaged in these roles tend to follow specific interruptibility strategies - integrating, combining, or segmenting private and work-related engagements. Understanding these strategies breaks new ground for attention and interruption management systems in ubiquitous computing.

When using digital technologies, various data traces are left behind for collection, storage and analysis. Innovative solutions for information systems are needed that mitigate privacy risks and foster information privacy. One mechanism to achieve this are privacy nudges. Nudges are a concept from behavioural economics to influence individual’s decisions. This paper focusses on building an integrative understanding of privacy nudging. Specifically, we conceptualize the constituting characteristics of privacy nudges by conducting a systematic literature review to cover the current state of knowledge in the interdisciplinary privacy nudge literature stream. We structure the intrapersonal factors that determine effectiveness for each privacy nudge in a morphological box and conceptualize on this basis current research coverage as well as demand for future research. Finally, we develop theoretical propositions contributing to the discussion of how to study and design effective privacy nudges that can pave the way for more privacy sensitive IT systems.

The self-improving system integration (SISSY) initiative-sometimes also called self-integration-started over six years ago. Recently, we have seen contributions approaching parts of the scope from different directions. In order to provide a better understanding how these attempts support the development of novel SISSY technology, this paper presents a definition of the term. In addition, it discusses the fundamental challenges stemming from the increasingly interconnected character of large-scale distributed and adaptive systems typically referred to as "Interwoven Systems", with these systems describing the basic motivation for SISSY research.

Der vorliegende Beitrag beschreibt den Diffusionsprozess von digitalen Technologien und Trends in Familienunternehmen (FU). Die Diffusion von digitalen Technologien und Trends in FU gestaltet sich wegen des Einfluss der Eigentümerfamilie auf das FU im Vergleich zu Nicht-FU grundlegend anders. Eigenschaften der Familie sowie des FU und der digitalen Technologien und Trends wirken sich zugleich negativ auf die Geschwindigkeit, mit der digitale Technologien und Trends den Diffusionsprozess im FU durchlaufen, aus. Dagegen entwickeln FU spezifische Strategien, die dabei helfen, diese Zeitbarrieren zu umgehen.

FCA2VEC: Embedding Techniques for Formal Concept Analysis. Dürrschnabel, Dominik; Hanika, Tom; Stubbemann, Maximilian. 2019.
- [ Abstract ]
- [ URL ]
- [ BibSonomy-Post ]
Embedding large and high dimensional data into low dimensional vector spaces is a necessary task to computationally cope with contemporary data sets. Superseding latent semantic analysis recent approaches like word2vec or node2vec are well established tools in this realm. In the present paper we add to this line of research by introducing fca2vec, a family of embedding techniques for formal concept analysis (FCA). Our investigation contributes to two distinct lines of research. First, we enable the application of FCA notions to large data sets. In particular, we demonstrate how the cover relation of a concept lattice can be retrieved from a computational feasible embedding. Secondly, we show an enhancement for the classical node2vec approach in low dimension. For both directions the overall constraint of FCA of explainable results is preserved. We evaluate our novel procedures by computing fca2vec on different data sets like, wiki44 (a dense part of the Wikidata knowledge graph), the Mushroom data set and a publication network derived from the FCA community.

Order diagrams are an important tool to visualize the complex structure of ordered sets. Favorable drawings of order diagrams, i.e., easily readable for humans, are hard to come by, even for small ordered sets. Many attempts were made to transfer classical graph drawing approaches to order diagrams. Although these methods produce satisfying results for some ordered sets, they unfortunately perform poorly in general. In this work we present the novel algorithm DimDraw to draw order diagrams. This algorithm is based on a relation between the dimension of an ordered set and the bipartiteness of a corresponding graph.

Internal crowd work has emerged as a new form of digital gainful employment that changes the nature of work. However, the possible effects of internal crowd work on the individual level have been largely neglected. In this paper, we therefore present our research in progress which is concerned with the effects of work characteristics in internal crowd work that have impact on the individual’s empowerment and satisfaction. Thus, we developed our research model and conducted an online survey amongst 118 internal crowd workers of a Swiss bank who were asked to test new software. Our expected contribution will increase the understanding of internal crowd work and provide important insights for organizations to (re-) design work on internal IT-platforms.

Interactive Collaborative Exploration using Incomplete Contexts. Felde, Maximilian; Stumme, Gerd. 2019.
- [ Abstract ]
- [ URL ]
- [ BibSonomy-Post ]
A common representation of information about relations of objects and attributes in knowledge domains are data-tables. The structure of such information can be analysed using Formal Concept Analysis (FCA). Attribute exploration is a knowledge acquisition method from FCA that reveals dependencies in a set of attributes with help of a domain expert. However, in general no single expert is capable (time- and knowledge-wise) of exploring knowledge domains alone. Therefore it is important to develop methods that allow multiple experts to explore domains together. To this end we build upon results on representation of incomplete knowledge [2, 8-10], adapt the corresponding version of attribute exploration to fit the setting of multiple experts and suggest formalizations for key components like expert knowledge, interaction and collaboration strategy. Furthermore we discuss ways of comparing collaboration strategies and suggest avenues for future research.

This article in the journal Gruppe. Interaktion. Organisation focusses on the relationship between interpersonal team processes and team satisfaction. Interpersonal team processes include conflict- and affectmanagement as well as motivational team processes. In this context, the role of task interdependence is examined. Student teams (n = 25) were interviewed to examine if the degree of task interdependence positively influences the relationship of interpersonal processes and team satisfaction. The results show on the one hand, that interpersonal team processes are positively related to perceived satisfaction at the team level and, on the other hand, that task interdependence is a moderator variable. Contrary to the assumption that task interdependencies reinforce the relationship between interpersonal processes and team satisfaction, it was shown that there is a compensatory effect in the low interdependence condition. Teams with lower task interdependence and good conflict-, affect- and motivation management are almost as satisfied with their team as teams with higher task interdependence and good conflict-, affect- and motivation management. Implications are discussed.

Recently, text mining has received special attention from both researchers and practitioners, since it enables the development of intelligent and automated services. Text mining has been influenced by different disciplines like computer science, statistics, computational linguistics and library and infor-mation sciences. However, text mining features that evolved in one particular discipline are often un-known or rarely used in the other disciplines. No scientific feature framework exits which facilitates costly feature engineering and evaluation. Therefore, we aim to develop a novel text mining feature taxonomy, which helps researchers and practitioners to develop, refine, compare and evaluate their text mining studies. In this research in progress paper, we focus on laying the foundation for our tax-onomy development by presenting our first two research cycles. Here, we were aiming for diversity, not completeness. We derived five dimensions and classified different text features accordingly to pro-vide a deeper understanding.

Im Folgenden wird die Umsetzung einer Lerneinheit in der praktischen Ausbildung von Handwerker*innen mithilfe von interaktiven 3D-360°-Videos vorgestellt. Vorhandene Inhalte aus dem Projekt FAINLAB wurden dabei als interaktive immersive Anwendung für das Erlernen der Herstellung eines Fliesenspiegels umgesetzt. Die Anwendung kann mithilfe eines Smartphone-basierten Head-Mounted Displays (HMD) genutzt werden und ermöglicht durch niedrige Kosten eine breite Verwendung in der Ausbildung. Die Interaktion wird mittels mehrerer Schaltflächen ermöglicht, die per Blicksteuerung zu nutzen sind, wie eine formative Evaluation mit Studierenden absicherte. Es wird auf eine vergleichende Evaluation verwiesen, die zeigt, dass die Anwendung gegenüber dem ursprünglichen FAINLAB-Video bei gleichem Lernerfolg eine höhere Motivation der Lernenden bewirkt.

Knowledge seeking is the default activity in online communities and therefore important for their functioning. Existing research studies on why members seek knowledge overlook other factors than a simple need for knowledge, resulting in an extremely narrow body of knowledge. We propose that a need for advice can increase knowledge seeking and is further shaped by perceptions of reciprocity, self-esteem, and identification with the community. By surveying 186 respondents from 34 large online communities and applying OLS regression analyses, we find that knowledge seeking is driven by need for advice and identification, but not reciprocity. The results further show that members with high self-esteem seek less knowledge. Yet, the decision to seek knowledge depends on the level of self-esteem and this is predicted by need for advice. Our results contribute to the currently sparse body on knowledge seeking and add to the realization of necessary design attributes of online communities.

Knowledge graphs have recently become the state-of-the-art tool for representing the diverse and complex knowledge of the world. Examples include the proprietary knowledge graphs of companies such as Google, Facebook, IBM, or Microsoft, but also freely available ones such as YAGO, DBpedia, and Wikidata. A distinguishing feature of Wikidata is that the knowledge is collaboratively edited and curated. While this greatly enhances the scope of Wikidata, it also makes it impossible for a single individual to grasp complex connections between properties or understand the global impact of edits in the graph. We apply Formal Concept Analysis to efficiently identify comprehensible implications that are implicitly present in the data. Although the complex structure of data modelling in Wikidata is not amenable to a direct approach, we overcome this limitation by extracting contextual representations of parts of Wikidata in a systematic fashion. We demonstrate the practical feasibility of our approach through several experiments and show that the results may lead to the discovery of interesting implicational knowledge. Besides providing a method for obtaining large real-world data sets for FCA, we sketch potential applications in offering semantic assistance for editing and curating Wikidata.

In diesem Beitrag wird ein Konzept zur Integration einer kollaborativen Roboterunterstützung an einem manuellen Montagearbeitsplatz vorgestellt. Dazu wurde exemplarisch ein Arbeitsplatz in der Wellenvormontage der Getriebefertigung in der Automobilindustrie betrachtet. Die Arbeitsprozesse bei der manuellen Montage wurden analysiert und das darauf basierende Konzept in einem vollfunktionsfähigen Mock-up umgesetzt, welcher die Montage ohne und mit Roboterunterstützung ermöglicht. Auf Basis dieses Mock-ups wurde eine Nutzerstudie (n = 8) durchgeführt, die die Ergonomie und Gebrauchstauglichkeit des Konzepts sowie das wirtschaftliche Potenzial der Roboterunterstützung evaluiert.

Chatbots are innovative text-based dialogue systems that are oftentimes used in digital customer service encounters, since chatbots offer a lot of potential to optimize the relationship with the customer. However, chatbots face various problems, such as low adoption and satisfaction rates as well as other negative reactions from the customer. Companies therefore need to consider different design features when developing their chatbots. Key for designing chatbots is the use of anthropomorphic design elements. In this study, we examine the two anthropomorphic design elements of personification, which includes a human like appearance of the chatbot, and socially oriented communication, which means a more sensitive and extensive communication behavior. We tested the influence of the two design elements on social presence, satisfaction, trusting beliefs and empathy. The results of our experiment support a significant influence of the two anthropomorphic design elements on social presence. In addition, our findings show the central role of social presence concerning chatbot perceptions. First, social presence has a strong direct influence on trusting beliefs, empathy and satisfaction. Second, social presence acts as a mediator for both anthropomorphic design elements on satisfaction with a chatbot. The derived implications provide a theory for understanding anthropomorphic design elements related to chatbots and we offer design principles for practitioners that enable more effective chatbot implementations.

Social network analysis is playing an increasingly important role in sociological studies. At the same time, new technologies such as wearable sensors make it possible to collect new types of social network data. We employed RFID tags to capture face-to-face interactions of participants of two consecutive Ph.D. retreats of a graduate school on climate research. We use this data in order to explore how it may support ethnographic observations and to gain further insights on scholarly interactions. The unique feature of the data is the opportunity to distinguish short and long conversations, which often have a different nature from a sociological point of view. Furthermore, an advantage of this data is the availability of socio-demographic, research-related, and situational attributes of participants. We show that, even though an interaction partner is often found rather randomly during coffee breaks of retreats, a strong homophily between participants from the same institutions or research areas exists. We identify cores of the networks and participants who play ambassador roles between communities, e.g., persons who visit the retreat for the second time are more likely to be ambassadors. Overall, we show the usefulness and potential of RFID tags for scientometric studies.

Die vorliegende Studie vergleicht den Einsatz von 3D-360°\hbox{-}}Lernvideos mit konventionellen Lernvideos bei der praktischen Ausbildung von Handwerkern. Es wurde die Hypothese geprüft, dass Motivation und Ablenkung durch die Technologie einen gegensätzlichen Einfluss auf den Lernerfolg haben und so die vorliegenden gemischten Befunde in diesem Feld erklären. Insgesamt 20 Auszubildende des ersten Lehrjahrs der Ausbildung zum Hoch- bzw. Tiefbaufacharbeiter lernten entweder mit konventionellen Lernvideos am Laptop oder mit 3D\hbox{-}}360°-Videos, die auf einem Smartphone\hbox{-}}basierten Head-Mounted Display angeschaut wurden. Der Lernerfolg wurde anhand einer praktischen Aufgabe gemessen, die von zwei unabhängigen Ratern bewertet wurde. Die durch die Lernmethode ausgelöste Motivation und Ablenkung der Lernenden wurde mithilfe von Fragebögen gemessen. Wie erwartet zeigte sich in der Gruppe der mit 3D\hbox{-}}360°\hbox{-}}Videos Lernenden sowohl eine höhere Motivation als auch eine höhere Ablenkung als in der Kontrollgruppe. Der Lernerfolg unterschied sich nicht zwischen den Gruppen. Die erwarteten Korrelationsmuster zur Unterstützung der weiteren Teilhypothesen konnten nicht gefunden werden.

Um die Attraktivität des öffentlichen Nahverkehrs zu erhöhen, wurde ein Mobilitätsassistenzsystem (MAS) konzipiert, das die Nutzer_innen in den Bereichen Anschlusssicherung und Belegungszustand sowie durch einen integrierten Lieferdienst unterstützt. Dazu wurde eine Anforderungserhebung mit Experten (n = 5) und Nutzer_innen (n = 426) durchgeführt, womit auch die Anforderungen von älteren Menschen und Menschen mit Einschränkungen besonders berücksichtigt werden sollten. Entgegen der Erwartungen ist das MAS für diese Gruppen nicht attraktiver als für andere Nutzer_innen. Die meisten Nutzer_innen wünschen sich die Interaktion mittels einer App, ältere Menschen und Menschen mit Einschränkungen bevorzugen andere Schnittstellen.

Ein benutzerzentrierter Entwicklungsansatz kann in Technologieentwicklungsprojekten dazu genutzt werden, um nachhaltige, sozial verantwortliche Gestaltungslösungen zu fördern. Dieser Ansatz rückt den Menschen und seine Aufgaben in den Fokus der technischen Systementwicklung und bezieht Benutzer sowie weitere Beteiligte von Anfang an fortlaufend in den Entwicklungsprozess ein. So wird sichergestellt, dass die entwickelten Systeme, Dienstleistungen und Produkte eine hohe Gebrauchstauglichkeit und Akzeptanz aufweisen und dass auch langfristige Folgen der Nutzung betrachtet werden. Dieser Beitrag gibt einen Überblick über das methodische Vorgehen mit diesem Ansatz und beschreibt am Beispiel eines mehrjährigen Verbundforschungsprojektes die konkrete praktische Anwendung mit exemplarischen Methoden.

In this paper, we evaluate different popular voting strategies for fusion of classifier results. A convolutional neural network (CNN) and different variants of random forest (RF) classifiers were trained to discriminate between 15 tree species based on airborne hyperspectral imaging data. The spectral data was preprocessed with a multi-class linear discriminant analysis (MCLDA) as a means to reduce dimensionality and to obtain spatial–spectral features. The best individual classifier was a CNN with a classification accuracy of 0.73 +/− 0.086. The classification performance increased to an accuracy of 0.78 +/− 0.053 by using precision weighted voting for a hybrid ensemble of the CNN and two RF classifiers. This voting strategy clearly outperformed majority voting (0.74), accuracy weighted voting (0.75), and presidential voting (0.75).

Smarte persönliche Assistenten von Amazon, Google und zahlreichen anderen Anbietern ermöglichen es, qualitativ hochwertige elektronische Dienstleistungen anzubieten. Gleichzeitig bringen diese Systeme auch viele Risiken mit sich. Berichte von diskriminierenden oder unverständlichem Systemverhalten häufen sich und verursachen Skepsis in der Gesellschaft. Diesen Problemen kann mit einer gleichermaßen rechtsverträglichen und qualitätsorientierten IT-Gestaltung entgegengewirkt werden. In diesem Beitrag werden Rechtsverträglichkeit und Dienstleistungsqualität als elementare Ziele für die Gestaltung smarter persönlicher Assistenten eingeführt. Zudem werden Zielkonflikte wie die Personalisierung von Leistungen bei gleichzeitiger Datensparsamkeit diskutiert und Implikationen für die Systemgestaltung erläutert.

Due to the advent of digitization, service innovation has become even more important for both business and service research alike. Current service systems engineering approaches have employed a recombinant perspective that follows innovation mechanisms to leverage existing company resources for new service innovations. Employing these innovation mechanisms is still challenging, since there is little support on how to structure and identify these mechanisms. We propose a model-based service system engineering approach to structure existing resources into one formal model, enabling the formalization of service innovation mechanisms. The formalized service innovation mechanisms allow for a graphical illustration and enable future research to apply functions to analyze how innovation impacts entire or specific parts of service systems. Furthermore, the mathematical model enables an object-oriented value-driven perspective on service systems and is basis for graphical software tools. We contribute to literature by formalizing service innovations and its mechanisms in the context of service systems and by combining concepts of service innovation and service systems engineering. We do so by a) formalizing service innovation mechanisms and b) demonstrating the application of formal service innovations along one specific software implementation case. For practice, the service system model can with simulating the effects of service innovations.

This contribution provides a short introduction into the conceptual and socio-technical development of privacy. It identifies central issues that inform and structure current debates as well as transformations of privacy spurred by digital technology. In particular, it highlights central ambivalences of privacy between protection and de-politicization and the relation of individual and social perspectives. A second section connects these issues to the influential texts and discussions on digital privacy. In particular, we will demonstrate privacy in digital societies is to be conceived in a novel way, since contemporary socio-technical conditions unsettle central assumptions of established theories: forms of perceptions, social structure or individual rights. Thus, a final third paragraph summarises theoretical innovations triggered by this situation – especially research from computer science to the social sciences and law and philosophy highlighting the requirement to take groups, social relations and broader socio-cultural contexts into account.

Digitale Daten gelten sowohl als Quelle für Wirtschaftswachstum, Innovation und Arbeitsplätze wie auch als Treiber der datenbasierten Reorganisation praktisch aller gesellschaftlichen Bereiche („Datafizierung“). Die datenökonomisch befeuerten Transformationsprozesse des Sozialen werfen dementsprechend vielfältige Fragen auf: Welche Daten sollen von wem wie verwertbar sein? Wie lässt sich legitime Verfügungsmacht gestalten? Usw. Der Band behandelt diese Fragen aus interdisziplinärer Perspektive.

AbstractMulti-agent systems need to communicate to coordinate a shared task. We show that a recurrent neural network (RNN) can learn a communication protocol for coordination, even if the actions to coordinate are performed steps after the communication phase. We show that a separation of tasks with different temporal scale is necessary for successful learning. We contribute a hierarchical deep reinforcement learning model for multi-agent systems that separates the communication and coordination task from the action picking through a hierarchical policy. We further on show that a separation of concerns in communication is beneficial but not necessary. As a testbed, we propose the Dungeon Lever Game and we extend the Differentiable Inter-Agent Learning (DIAL) framework. We present and compare results from different model variations on the Dungeon Lever Game.

The amount of online reviews is growing significantly. Between 2014 and 2017 the number of reviews for TripAdvisor grew by 300% and for Yelp by 208%. However, not all online reviews are equally valuable. Some reviews are perceived to be more helpful or trustworthy then others. Hence, a plethora of scholars have investigated the role of online reviews and researched factors and characteristics determining its helpfulness. Nevertheless, mixed findings were found. Consequently, the purpose of our paper is to present a holistic and representative analysis of the literature on factors indicating the helpfulness of online reviews. In total, we analyzed 81 journal articles and inductively created a framework resulting in four dimensions: review-related factors, reviewer-related factors, reader related factors and environment-related factors. The results reveled that researchers mainly focused on factors of the first two dimensions and that the findings are inconsistent and need to be solved by future research.

Die digitale Transformation der Verwaltung setzt auch eine digitale Kommunikation zwischen Bürger oder Organisationen (z. B. Unternehmen) und Verwaltung voraus. Soweit diese asynchron mit Hilfe von Schriftzeichen erfolgt, handelt es sich um eine elektronische Schriftkommunikation. Sie bedarf einer technischen und rechtlichen Absicherung, wenn es um die Kommunikation rechtlich schwerwiegender Willenserklärungen geht. Die Absicherung kann durch Sicherungsmechanismen, wie sie Vertrauensdienste zur Verfügung stellen oder durch ausreichend sichere Kommunikationsdienste wie De-Mail erfolgen.

For localization and mapping of indoor environments through WiFi signals, locations are often represented as likelihoods of the received signal strength indicator. In this work we compare various measures of distance between such likelihoods in combination with different methods for estimation and representation. In particular, we show that among the considered distance measures the Earth Mover's Distance seems the most beneficial for the localization task. Combined with kernel density estimation we were able to retain the topological structure of rooms in a real-world office scenario.

Die Steigerung der Attraktivität öffentlicher Verkehrsmittel (ÖV) ist eine zentrale Komponente zur Verbesserung der Lebensqualität im urbanen Raum. Zwei Drittel der zurückgelegten Wege in Kernstädten entfallen auf Freizeitaktivitäten, Einkauf und private Erledigungen, wobei der ÖV-Nutzung oft der unbequeme Transport von Einkäufen oder Gepäck sowie die Unsicherheit bzgl. verfügbarer Sitzplätze und des Erreichens von Anschlüssen entgegenstehen. Deshalb wurde in diesem Projekt ein Mobilitätsassistenzsystem konzipiert, das den Nutzer bedarfsgerecht entlang seiner Reisekette unterstützt. Neben der intermodalen Reiseplanung bietet es einen innovativen innerstädtischen Lieferdienst, der mit Gepäckabgabe, Transport und Zustellung die gesamte Lieferkette abdeckt. Gemeinsam mit innerstädtischen Verkehrsdienstleistern wurde die Erfassung und Echtzeit-Bereitstellung von Belegungsdaten untersucht, deren Berücksichtigung neue individuelle Adaptionsmöglichkeiten schafft. Weiterhin wurde eine Anschlusssicherung konzipiert, die dem Nutzer verlässliche Informationen zur Anschlusserreichung bereitstellt und durch Anmeldung von Anschlusswünschen die Sicherstellung durch die Verkehrsdienstleister ermöglicht. Das Assistenzsystem bietet eine integrierte Lösung für die getrennte Personen- und Gepäckbeförderung und integriert Daten zu Belegung und Anschlüssen, die bisher nicht in Echtzeit bereitgestellt werden.

Over the last decades, physical inactivity has become one of the leading health risk factors in modern societies. To incentivize people to be more physically active, gamified health behavior change support systems (HBCSSs) are a promising approach. These systems often make use of gamification to keep their users engaged over a sustained period of time. However, despite its popularity, gamification often fails due to insufficient designs, which neglect users’ needs. Building on extant research that investigated users’ preferences in other gamification contexts, we conduct a survey among 447 potential users of HBCSSs for physical activity, using a best-worst-scaling approach. Our results indicate that users generally prefer the game design elements progress, goals, points, and levels, which is partially different from past research on preferred game design elements in other contexts. Thus, our research contributes to the understanding of contextual differences in users’ gamification preferences.

Die noch recht neue DSGVO hat einige Änderungen mit sich gebracht, welche sich in der Praxis erst noch bewähren und innovativ umgesetzt werden müssen. Insbesondere das Arbeitsumfeld wird von der fortschreitenden Digitalisierung stark verändert und sieht sich neuen Herausforderungen des Datenschutzes gegenüber. Ein Ansatz, diesen Herausforderungen zu begegnen, könnte die Integration von Privacy Nudges in digitale betriebliche Systeme sein. Ziel von Privacy Nudges ist es dabei, den Entscheidungsprozess in digitalen Entscheidungsumgebungen gezielt zu mehr Schutz von personenbezogenen Daten und Privatheit zu beeinflussen. Diesem Ansatz nähert sich dieser Beitrag interdisziplinär durch Erkenntnisse aus der verhaltensökonomischen, informatischen und der rechtswissenschaftlichen Literatur. Schließlich werden verschiedene Szenarien für den Einsatz von Privacy Nudges in digitalen Arbeitssystemen beschrieben und bewertet.

What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a research agenda comprising three design areas – Machine artifact, Collaboration, and Institution – and 17 dualities – significant effects with the potential for benefit or harm. The MaT research agenda offers a structure and archetypal research questions to organize early thought and research in this new area of study.

The increasing prevalence of learner-centred forms of learning as well as an increase in the number of learners actively participating on a wide range of digital platforms and devices give rise to an ever-increasing stream of learning data. Learning analytics (LA) can enable learners, teachers, and their institutions to better understand and predict learning and performance. However, the pedagogical perspective and matters of learning design have been underrepresented in research thus far. In our paper, we propose a general design framework that includes critical dimensions of LA and assists in creating LA services that support educational practice. On the basis of a two-dimensional framework (individual vs. social, reflection vs. prediction), we then identify four generic approaches to LA aimed at improving learning process and learning outcomes. To demonstrate the application, four use cases are outlined that are based on four previously elaborated generic approaches to LA. Finally, we discuss the validation of the model and close with an outlook on relevant future research.

If the Environmental Humanities (EH) matter, an essential concern is whether we can speak of the possibility of a philosopher of literary and ecological identity. This paper discusses the intersection points of the Environmental Humanities to the wider scientific debate. It suggests that the EH are suited to help construct knowledge for sustainable futures. The arrival of the Anthropocene provides opportunities to cross disciplinary boundaries. Ecocriticism investigates the complex and contradictory relationship between humans and the environment in literature. Ideas of citizenship allow space for conversation about civic responsibility and stewardship. Animal studies intervenes deeply across the humanities, which acknowledges the interspecies imaginary. Future techno-scientific developments make us reconsider distinctions between humans, animals, and machines. The concept of the posthuman emphasizes how profound changes will be for all species. Serious questions might best be answered by environmental philosophy, which articulates the impact of the environment on humans. New Materialism explains why matter matters, and has clear implications for the study of the environment. Work in postcolonial and digital media provides a platform to challenge geographic borders as well as reconsider national contexts. Essentially, this paper asserts that the EH is building critical mass, and functions as a lightning rod between the arts and sciences. Such a development has profound consequences for the future of literary studies.

In recent decades, the number of students per lecturer at universities has constantly risen. In these learning scenarios, individual lecturer support for helping students actively acquiring new knowledge is hardly possible. However, active student behavior is necessary for successful learning. Smart Personal Assistants such as Amazon’s Alexa or Google’s Home promise to fill this gap by being students’ individual tutors. In order to understand what students expect from Smart Personal Assistants as tutors and how they interact with them, we will carry out an experiment. In this research in progress paper, we present our experiment design, where we observe the individual interaction between students and a Smart Personal Assistant tutor and between students and a human tutor applying the same methods in both cases. Drawing on the concepts of parasocial interaction and trust, we derive hypotheses, present the Smart Personal Assistant development and explain the experiment process in detail.

Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary collaborative work practices. We use a design science approach to identify the main challenges with the original FPM technique, derive requirements and design a revised modeling technique that is based on the current technique enriched by BPMN 2.0 elements. This paper contributes to the CE literature by offering a revised FPM technique that assists CE-designers to capture new forms of collaborative work practices.

Despite a growing body of research about the design and use of Smart Personal Assistants, such as Google’s Assistant or Amazon’s Alexa, existing work has mainly focused on their use as task support for individual users in rather simple problem scenarios. Little is known about their ability to improve collaboration among multiple users in more complex problem settings. Using a mixed-method approach, we investigate the value of Smart Personal Assistants as facilitators by directly comparing 40 groups of three who either interact with a Smart Personal Assistant or a scripted human facilitator in a complex problem-solving scenario. The results indicate that groups interacting with Smart Personal Assistant facilitators show significantly better task outcomes and higher degrees of collaboration quality. A conversation analysis approach further analyzes differences in human SPA communication. Our work contributes to computer-supported cooperative work research and emphasizes the value of conversation analysis approaches in HCI research.

Less is known about their ability to improve collaboration among multiple users in more complex problem settings. In our study, we directly compare 21 groups who either use a Smart Personal Assistant tutor or a human tutor when solving a problem task. The results indicate that groups interacting with Smart Personal Assistant tutors show significantly higher task outcomes and higher degrees of collaboration quality compared to groups interacting with human tutors. The results are used to suggest areas for future research in the field of computer-supported collaboration.
When Indoor Localization Meets New Communication Technologies. Xu, Y.; David, K. In 2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), pp. 1–4. IEEE, Honolulu, Hawaii, USA, 2019.

Accurate and low-cost indoor localization continues to be a research challenge. The emerging communication technologies in 5G and 802.11 standards (e.g., 802.11n and 802.11 ac), such as massive MIMO and mmWave, provide opportunities for accurate indoor localization. Meanwhile, location information is also critical for the development of new technologies, e.g., directional communication using beamforming. It leads to a synergistic relationship between localization and communication. In this paper, we review the potential benefits of the emerging communication technologies (i.e., smart antennas, Massive MIMO, mmWave, beamforming, CSI) for indoor localization. It may provide a useful guide for researchers who are interested in developing indoor localization systems based on emerging communication technologies.

Smart Home technologies are promising to enhance quality of life, autonomous living of elderly people and home security. Yet, uncertainty in terms of personal benefits, functionality, cost, privacy and security features influences potential users' decision processes. The vision of this research thus is to support end users' informed decision-making in terms of Smart Home technologies. We developed and tested a prototype of an interactive Smart Home configurator that provides users with targeted information according to their interests. It visualizes Smart Home processes and implications for privacy and security to increase transparency and reduce uncertainty in the decision-process. Ideas for further improving and extending the concept of the Smart Home configurator are discussed.

Mobile Cloud Computing (MCC) requires an infrastructure that is combining the capabilities of resource-constrained but mobile and context-aware devices with that of immovable but powerful resources in the cloud. Application execution shall be boosted and battery consumption reduced. Our goal is to relieve mobile devices by enabling applications to cooperate transparently with components provided by third parties remotely, locally, or both. For this purpose, we developed SAM - the Semantic-aware Middleware - and the SAM Store. The latter resembles a registry. It allows component providers to publish semantically enriched interfaces and to offer corresponding local and remote implementations. SAM makes use of the SAM Store to match local interprocess communication (IPC) messages transparently against local and remote components. This architecture facilitates the integration of powerful, but resource-intensive remote components, which may be prioritized over local ones, and fosters various patterns of cooperation that demonstrate useful solutions in the area of MCC. By means of a realistic scenario, our evaluation proves the efficiency with respect to latency and practicality.

To profit from crowdsourcing, organizations can engage in four different approaches: microtasking, information pooling, broadcast search, and open collaboration. This article presents 21 governance mechanisms that can help organizations manage their crowdsourcing platforms. It investigates the effectiveness of these governance mechanisms in 19 case studies and recommends specific configurations of these mechanisms for each of the four crowdsourcing approaches. Also, it offers guidance to organizations that host a crowdsourcing platform by providing recommendations for implementing governance mechanisms into their platforms and building up governance capabilities for crowdsourcing.

The purpose of this study was to investigate the role of information and communication technology (ICT) use for employees by exploring affective ICT events and their relation to employee recovery. We conducted two daily diary studies with knowledge workers in Germany. In study 1 (N = 153), we followed a qualitative approach by developing a taxonomy of negative and positive ICT events at work and at home. We found 11 negative (e.g., multichannel use, work e-mails in the evening) and 10 positive ICT event clusters (e.g., utilizing idle times, availability at home). In study 2 (N = 154), we examined how the occurrence of ICT-related events in the evening is related to detachment from work and sleep quality using a multilevel design. Study 2 provided a differentiated picture of relationships between evening ICT events and recovery. Overall, results indicate that work-related ICT events in the evening—even in cases where they are appraised as positive—are detrimental for employee recovery. Our study contributes to the refinement of the operationalization of ICT use for future analyses of ICT impacts and sheds light on the differential effects of specific types of ICT events. ICT use conceptualized as the occurrence of affective events helps to advance our understanding of the diversity of ICT-related experiences. The negative effects of handling work e-mails at home imply that organizations should engage in optimizing their “e-mail culture.”

MOOCs attract learners from various cultural backgrounds with differing educational beliefs and learning preferences. Research has long acknowledged that culture has an impact on the adoption and use of information technology. Cultural differences can cause conflicts, especially when learners provide each other with feedback during the peer assessment process. With this paper, we use a design science approach to create a cultural sensitive peer assessment process in MOOCs. Based on Hofstede’s cultural dimension theory we derive design elements and evaluate them in a qualitative and comparative study with Swiss and Chinese students. Our results show that different cultures prefer different designs. Consequently, our key contribution is the practical elaboration of design elements, which can be integrated in MOOCs to provide a better learning experience. Further, we contribute to cross-cultural theory by using an existing framework and adapting it to a new and relevant phenomenon: MOOCs.

To address the question in the subtitle of this article, we start by discussing earlier mobile communication systems, beginning with the first analog wireless cellular standards, then moving on to second generation (2G) [or Global System for Mobile Communications (GSM)], passing third generation (3G) and fourth generation (4G), and proceeding to fifth generation (5G). First, we present each generation's key achievements in terms of user services, each generation's technologyrelated factors of success (called innovations) as well as its relation to regulation, and each generation's potential deficiencies.

The creative potential from innovative contributions of the crowd constitutes some critical challenges. The quantity of contributions and the resource demands to identify valuable ideas is high and remains challenging for firms that apply open innovation initiatives. To solve these problems, research on algorithmic approaches proved to be a valuable way by identifying metrics to distinguish between high and low-quality ideas. However, such filtering approaches always risk missing promising ideas by classifying good ideas as bad ones. In response, organizations have turned to the crowd to not just for generating ideas but also to evaluate them to filter high quality contributions. However, such crowd-based filtering approaches tend to perform poorly in practice as they make unrealistic demands on the crowd. We, therefore, conduct a design science research project to provide prescriptive knowledge on how to combine machine learning techniques with crowd evaluation to adaptively assign humans to ideas.

It is well known that any bipartite (social) network can be regarded as a formal context $$(G,M,I)$$. Therefore, such networks give raise to formal concept lattices which can be investigated utilizing the toolset of Formal Concept Analysis (FCA). In particular, the notion of clones in closure systems on $$M$$, i.e., pairwise interchangeable attributes that leave the closure system unchanged, suggests itself naturally as a candidate to be analyzed in the realm of FCA based social network analysis. In this study, we investigate the notion of clones in social networks. After building up some theoretical background for the clone relation in formal contexts we try to find clones in real word data sets. To this end, we provide an experimental evaluation on nine mostly well known social networks and provide some first insights on the impact of clones. We conclude our work by nourishing the understanding of clones by generalizing those to permutations of higher order.
Gestaltungsempfehlungen für touchscreenbasierte Benutzungsschnittstellen. Domhardt, M. Kassel University Press, Kassel, 2018.
- [ Abstract ]

- [ BibSonomy-Post ]
Bisher erfolgt die Gestaltung von Touchscreensystemen nach Kriterien für ergonomische Eingabemittel oder der Softwareergonomie. Der allgemeine Charakter dieser Empfehlungen deckt nicht touchscreenspezifische Besonderheiten ab. Hersteller- und softwarespezifische Design Guides enthalten keine Hinweise zur Berücksichtigung der technologiebedingten Interaktionsmöglichkeiten und -einschränkungen der verschiedenen technischen Komponenten eines Touchscreensystems. Bisher existiert kein Gestaltungsansatz, der die touchscreenspezifischen Besonderheiten systematisch berücksichtigt. Die technologischen Möglichkeiten von Touchscreensystemen sowie die die Gefahr einer physischen Überbeanspruchung des belasteten Bewegungsapparates werden dadurch bei der Systemgestaltung nur unzureichend berücksichtigt. Im Rahmen dieser Arbeit wurde daher das Ziel verfolgt, einen ganzheitlichen Gestaltungsansatz zu erarbeiten, der die Besonderheiten der Touchscreentechnologien und -interaktion durch spezifische Gestaltungsempfehlungen berücksichtigt. Als Lösungsansatz wurde die Erweiterung bestehender Modelle um die Besonderheiten touchscreenbasierter Systeme verfolgt. Im ersten Schritt erfolgte die systematische Auswahl eines Modells eines interaktiven Systems als geeignetes Basismodell für Touchscreensysteme. Anschließend wurde dieses Modell um die charakteristischen Bestandteile eines Touchscreensystems erweitert. Anhand dieses Modells wurden Wissenslücken in den theoretischen Grundlagen identifiziert und daraus sechs Forschungsfragen abgeleitet. Um die Fragen systematisch zu beantworten, wurden Literaturanalysen und empirische Studien konzipiert, durchgeführt und ausgewertet. Die theoretischen Grundlagen wurden mit den erarbeiteten Ergebnissen der Analysen und empirischen Studien zusammengeführt und als Basis für die Formulierung touchscreenspezifischer Gestaltungsempfehlungen genutzt. Diese Empfehlungen wurden anschließend im Basismodell verankert, um so einen ganzheitlichen Gestaltungsansatz für Touchscreensysteme zu erhalten. Für die praktikable Anwendung des Ansatzes wurde dieser in den menschzentrierten Gestaltungsprozess integriert. Die Anwendbarkeit konnte anhand eines Praxisbeispiels erfolgreich demonstriert werden. Die Ergebnisse dieser Arbeit erleichtern die Gestaltung touchscreenbasierter Systeme im Rahmen des menschzentrierten Gestaltungsprozesses. Auch eine formative analytische Evaluierung entsprechender Systeme kann durch die erarbeiteten touchscreenspezifischen Gestaltungsempfehlungen vereinfacht werden, indem diese als Konformitätskriterien verwendet werden.

As Wi-Fi fingerprinting is a promising approach for indoor localization, one of the major challenges is understanding how fast fading and device heterogeneity problems influence the performance of the Wi-Fi fingerprinting systems. In this paper, we experimentally investigate the influence of fast fading and the device heterogeneity problems on the Wi-Fi RSS values, as well as on the performance (i.e., the recognition rate) of a Wi-Fi fingerprinting system WHERE. Besides, we also compare the performance of Wi-Fi fingerprinting in the experimental scenarios and in the real scenarios with the consideration of the fast fading problem. It concludes that both fast fading and device heterogeneity heavily influences the RSS values. However, the influence of fast fading on the performance of the Wi-Fi fingerprinting system can be mitigated when the Wi-Fi data is collected in the real scenarios.
Understanding Job Satisfaction of Crowd Workers: An Empirical Analysis of Its Determinants and Effects. Durward, David; Blohm, Ivo. In Multikonferenz Wirtschaftsinformatik (MKWI). Lüneburg, Germany, 2018.

Crowd work has emerged as new pattern of digitally mediated collaboration. In this paper, we focus on the determinants and effects of crowd workers’ job satisfaction – a perspective that has been largely neglected by current crowdsourcing research. We report results from a survey of 161 crowd workers participating in crowdsourced software testing. Our research shows that job satisfaction mediates the effects of monetary rewards, hedonic value, and cognitive stimulation on the intention to participate in future testing tasks. By contrast, factors of work context (i.e., flexibility and provided information) have no effects. We contribute to the literature by unraveling job satisfaction as causal mechanism influencing future participation. For practice, our results help to design more effective tasks in crowd work.
How Digital Nudges Influence Consumers - Experimental Investigation in the Context of Retargeting. Eigenbrod, Laura; Janson, Andreas. In European Conference on Information Systems (ECIS). 2018.

Retargeting is an innovative online marketing technique in the modern age. Although this advertising form offers great opportunities of bringing back customers who have left an online store without a com-plete purchase, retargeting is risky because the necessary data collection leads to strong privacy con-cerns which, in turn, trigger consumer reactance and decreasing trust. Digital nudges – small design modifications in digital choice environments which guide peoples’ behaviour – present a promising concept to bypass these negative consequences of retargeting. In order to prove the positive effects of digital nudges, we aim to conduct an online experiment with a subsequent survey by testing the impacts of social nudges and information nudges in retargeting banners. Our expected contribution to theory includes an extension of existing research of nudging in context of retargeting by investigating the effects of different nudges in retargeting banners on consumers’ behaviour. In addition, we aim to provide practical contributions by the provision of design guidelines for practitioners to build more trustworthy IT artefacts and enhance retargeting strategy of marketing practitioners.

Retargeting is an innovative online marketing technique because it can provide consumer-specific advertising content based on consumers’ browsing behavior that meet consumers' prefer-ences and interests. Although this advertising form offers great opportunities of bringing back customers who have left an online store without to complete a purchase, retargeting is risky be-cause the necessary data collection leads to strong privacy concerns which in turn, trigger con-sumer reactance and decreasing trust. Digital nudges – small design modifications in digital choice environments which guide peoples’ behavior – present a promising concept to bypass these negative consequences of retargeting. In order to explore the positive effects of digital nudges in retargeting banners, we conducted a between-subject experiment with a subsequent survey which examines the impacts of social nudges (likes of friends) and privacy nudges (disclosure of privacy policy and purpose of retargeting banners). Whereas the social nudge led to a negative impact on consumers’ privacy concerns and a positive impact on consumers’ booking behavior, the privacy nudge did not have any significant impact. A combination of social nudge and privacy nudge showed that the privacy nudge negatively moderated the positive relationship between social nudge and consumers’ booking behavior. The derived implications provide a theory for under-standing nudges in digital environments and we offer design principles for practitioners that enable better retargeting outcomes.

Eine große Anzahl an verfügbaren Lernplattformen und eine stetige Veränderung des Markts durch neue Anbieter erschweren die Auswahl eines geeigneten Systems. Für eine Marktübersicht wurde eine Literatur- und Internetrecherche von verfügbaren Lernplattformen durchgeführt. Die Rechercheergebnisse wurden aussagefähigen Kategorien wie bspw. Administration, Didaktik, Kommunikation oder Technik zugeordnet. Durch die Unterteilung der Lernplattformen in Kategorien lassen sich die Rechercheergebnisse schnell anhand eigener Anforderungen filtern, um geeignete Plattformen für bestimmte Anforderungen zu identifizieren. Die Recherche ergab, dass sich einige Produktmerkmale, bspw. die mobile Zugänglichkeit von E-Learning-Material, als Basiseigenschaften etabliert haben, wohingegen VR-/AR-Technologien bisher nicht berücksichtigt werden.

Die vorliegende Studie untersucht, woran sich Menschen an komplexen Verkehrsknotenpunkten orientieren und welche Probleme hierbei auftreten. Dafür wurden die Blickbewegung gemessen und die Schritte gezählt, während die zwölf Teilnehmer drei Navigationsaufgaben durch den Frankfurter Flughafen absolvierten. Anschließend wurde die Retrospektive Think-Aloud-Methode genutzt, um einen Einblick in Gedanken und Strategien der Probanden zu bekommen. So konnten Problemstellen, wie z. B. die Suche auf Übersichtsplänen oder das Bestimmen der derzeitigen Etage, identifiziert werden, aus denen Gestaltungsempfehlungen für eine Fußgängernavigation mit Datenbrillen abgeleitet werden.

Geometric analysis is a very capable theory to understand the influence of the high dimensionality of the input data in machine learning (ML) and knowledge discovery (KD). With our approach we can assess how far the application of a specific KD/ML-algorithm to a concrete data set is prone to the curse of dimensionality. To this end we extend V.~Pestov's axiomatic approach to the instrinsic dimension of data sets, based on the seminal work by M.~Gromov on concentration phenomena, and provide an adaptable and computationally feasible model for studying observable geometric invariants associated to features that are natural to both the data and the learning procedure. In detail, we investigate data represented by formal contexts and give first theoretical as well as experimental insights into the intrinsic dimension of a concept lattice. Because of the correspondence between formal concepts and maximal cliques in graphs, applications to social network analysis are at hand.
Intrinsic Dimension of Geometric Data Sets. Hanika, Tom; Schneider, Friedrich Martin; Stumme, Gerd. 2018.

The curse of dimensionality is a phenomenon frequently observed in machine learning (ML) and knowledge discovery (KD). There is a large body of literature investigating its origin and impact, using methods from mathematics as well as from computer science. Among the mathematical insights into data dimensionality, there is an intimate link between the dimension curse and the phenomenon of measure concentration, which makes the former accessible to methods of geometric analysis. The present work provides a comprehensive study of the intrinsic geometry of a data set, based on Gromov's metric measure geometry and Pestov's axiomatic approach to intrinsic dimension. In detail, we define a concept of geometric data set and introduce a metric as well as a partial order on the set of isomorphism classes of such data sets. Based on these objects, we propose and investigate an axiomatic approach to the intrinsic dimension of geometric data sets and establish a concrete dimension function with the desired properties. Our mathematical model for data sets and their intrinsic dimension is computationally feasible and, moreover, adaptable to specific ML/KD-algorithms, as illustrated by various experiments.

Messaging applications are among the most popular internet applications and people use them worldwide on a daily basis. Their supporting infrastructure, though consisting of a multitude of servers, is typically under central control. This enables censorship and seamless user profiling. A fully decentralized infrastructure, with decentralized control and redundant data storage, can mitigate these dangers. In this paper we evaluate the basic ability of decentralized networks created by the network overlay and data storage protocol Kademlia to serve as a short-term data cache for messaging applications. Our results show, that reliable retrieval of up to 20 replicas is possible.

Die damit durchgeführte Studie (n = 21) fokussierte sich auf die Steigerung der Effizienz des Arbeitsprozesses durch die technische Unterstützung und die Verringerung der Beanspruchung für den Werker durch Übernahme eines Teils der Materialhandhabung durch den Roboter. Die Effizienzsteigerung und Beanspruchungsreduktion ließen sich statistisch signifikant belegen. Vor dem Hintergrund der Akzeptanz einer solchen Roboterunterstützung wurde auch die Gebrauchstauglichkeit betrachtet und positiv bewertet. Praktische Relevanz. Einerseits finden wissenschaftliche Studien zur Mensch-Roboter-Kollaboration häufig in vereinfachten oder künstlichen Setups bspw. der Handhabung von Bauklötzen oder in VR-Umgebungen statt, andererseits werden vor allem in Großunternehmen Versuchsstände realisiert, die öffentlichkeitswirksam präsentiert werden können, aber häufig eine gewissen Praxisferne aufweisen. Der Aufbau und die Nutzung eines Mock-ups, der sich möglichst nah am realen Montagearbeitsplatz orientiert und ausschließlich kommerziell verfügbare Standardkomponenten nutzt, zur Durchführung wissenschaftlicher Studien anhand tatsächlicher und in der Industrie häufig vorzufindender Arbeitsprozesse stellt hier die hohe praktische Relevanz und die Übertragbarkeit der Ergebnisse sicher.

Previous research assumed that work-related ICT use impairs psychological detachment from work. However, since past studies assessed both variables cross-sectionally, little is actually known about the direction of effects in the relationship. This 5-day diary study implemented a cross-lagged panel design to shed light on the relationship between work-related ICT use and detachment (N = 211 employees, N = 2816 data points). Contrary to current research consensus we found that psychological detachment was related to an increase in work- related ICT use, but not vice versa. Furthermore, our results support the notion that unfinished work tasks act as a job stressor preceding both variables. Our findings suggest that work-related ICT use should not be treated as a job stressor but as a strategy employees rely on to cope with a high workload.

Controlling an unmanned aerial vehicle is challenging and requires an intensive training. One cause is the teleoperation with the conventional input device, the remote control, whose functions are complicate. This paper presents an alternative concept for the teleoperation. Its realization includes a Thalmic Myo gesture control wristlet and a Microsoft HoloLens head-mounted display. These devices are used to implement an augmented reality interface, a tactile feedback and a gesture and speech input. Finally, this implementation has been evaluated with 30 participants and compared with a conventional remote control. The results show that the proposed interface is a good solution but does not reach the performance of the remote control.

Every year many vulnerable road users (VRUs), such as pedestrians or bicyclists, are killed or seriously injured in traffic accidents. To reduce the number of such traffic accidents several research groups are working on different solutions. The approach presented in this paper is based on wireless communications such as WLAN and 5G/LTE and a “context filter.” The “context filter” identifies vulnerable road users in potentially dangerous situations based on several inputs (e.g., location, movement direction). An identified dangerous situation is communicated between VRUs and cars using wireless communication. As one interesting context for identifying dangerous situations, this paper investigates how to recognize pedestrians stepping onto the road. Utilizing smartphone sensor data, the investigated approaches address three key challenges: inconsistent sensor data, overrepresentation of periodic activities, as well as the evaluation of the recognition. For each challenge, a possible solution is proposed. The results indicate that recognizing the “stepping onto the road” is possible and support the overall 5G based collision avoidance system.

Nudging Privacy in Digital Work Systems – Towards the Development of a Design Theory. Janson, Andreas; Schöbel, Sofia. In International Conference on Information Systems (ICIS). 2018.
- [ Abstract ]

- [ BibSonomy-Post ]
Digitization changes our society, the way we work and the way we generate value in work systems. More precisely, it equally affects how business and employees organize their work. While there is a tremendous innovation potential for businesses such as more flexible and efficient work arrangements, there are also tremendous privacy risks. Such privacy risks especially relate to issues that employees leave data traces in every working step while being oftentimes not aware of their generated data. Employees leave data traces on intranet platforms such as Wikis and on external work tools such as Slack and reveal not only personal information but also company insights. At the same time companies must handle new privacy regulations such as the European General Data Protection Regulation (GDPR) which do not only affect companies in the European countries but also providers of information systems (IS) all around the world that offer their services in Europe. Thus, innovative approaches for considering challenges that exist because of privacy related issues are needed. A promising approach to overcome the aforementioned privacy issues of digital working environments is the application of digital nudges in IS – small design modifications in digital choice environments which guide peoples’ behavior (Weinmann et al. 2016). The nudge theory – originally derived from behavioral economics– is based on the irrational behavior of human beings. A nudge “is any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives” (Thaler and Sunstein 2008, p. 6) and is typically applied in offline environments, e.g., to nudge individuals for being organ donors through a default opt-in. By relying on the concept of nudging, individuals in digital work system could be nudged to improve their decisions when disclosing data. This is especially prevalent, since many individuals are not aware about how their data is used. As such, there is a lack of research regarding nudging in context of digital work systems and privacy which should be addressed in a socio-technical research approach. By examining the impact and perception of digital nudges in work systems, we want to shed light on the application, design and effects of nudges to overcome challenges that arise because of privacy related issues. We therefore first examine use cases and requirements for nudging in digital work system under the consideration of users, companies and other stakeholders. Since we draw on a socio-technical view, we incorporate requirements that relate to a legal as well as an ethical perspective for nudging privacy. By this means, we develop a design theory for privacy nudging by an iterative design and evaluation process in the field. The ultimate goal is to improve decisions concerning data disclosure and, secondary, increase by this means trust and acceptance of digital work systems by lowering privacy concerns. By developing a design theory, we contribute to the body of knowledge with a more profound understanding of digital nudging in the context of privacy as well as with prescriptive design knowledge for nudging in digital work systems.

After publishing data on the Internet, the data publisher loses control over it. However, there are several situations where it is desirable to revoke published information. To support this, the European Commission has elaborated the General Data Protection Regulation (GDPR), which is mandatory for all countries in the European Union and must be applied from 25 May 2018. In particular, this regulation requires that providers must delete the data on user's demand. However, the data might already have been copied by third parties. Therefore, Article 17 of the GDPR includes the regulation that the provider must also inform all affected third parties about the user's request. Hence, the providers would need to track every access, which is hard to achieve. This technical infeasibility is a gap between the legislation and the current technical possibilities. To close this gap, we analyse the possibilities for a technical realisation of data deletion and propose a solution, which is based on the combination of the technical mechanisms and the obligation to follow the legal regulations of the GDPR. Our technical solution is a distributed and decentralized Internet-wide data revocation service (DRS). Hereby, we aim to support users to remain in control over their data even after publishing them on the Internet, and to give providers a possibility to follow the legal regulations of the Article 17 of the GDPR. With the DRS, the user is able to notify automatically and simultaneously all affected providers about her revocation request of a certain data object. Thus, we implicitly provide the notification of third parties about the user's request. Hereby, we propose two approaches how to distribute the revocation notification from users to providers: (1) to push the revocation requests to providers or (2) providers pull the revocation requests by themselves. Elaborating the DRS, protection of user's privacy and anonymity on the Internet is our central objective. To achieve this with a distributed and decentralized system, we supplement the DRS with a new privacy-aware fine-grained access control. We evaluate the DRS and its access control in terms of attacker resilience, computational and memory effort both through theoretical analysis and through simulations.

Does the Ability to Choose Matter? On the Relationship between Bring-your-own Behavior and IT Satisfaction. Klesel, Michael; Kampling, Henrik; Bretschneider, Ulrich; Niehaves, Björn. In Communications of the Association for Information Systems, 43(36), pp. 690–710. 2018.

Employees increasingly complete organizational tasks using privately owned consumer technologies such as private devices (e.g., smartphones) or private Internet accounts (e.g., email accounts). Higher satisfaction constitutes a major reason for this bring-your-own behavior (BYOB). However, little research has theoretically explored and empirically tested this assumption. This study sheds light on this phenomenon by analyzing the effect of BYOB on IT satisfaction. Drawing from social cognitive theory, we propose choice self-efficacy as a new construct that intermediates the relationship between BYOB and IT satisfaction. Building on results from survey data (n = 400), we provide new evidence that BYOB has a positive effect on IT satisfaction whereby choice self-efficacy plays a vital element as it mediates this relationship. Since IT satisfaction shapes how people use technology and how they perform with it, we derive important implications for future research on IT consumerization. Furthermore, we provide several conclusions for practitioners and discuss how to enhance IT satisfaction and choice self-efficacy.

Für die Entwicklung eines persönlichen, adaptiv lernenden Reiseassistenzsystems für den öffentlichen Verkehr auf Basis von Augmented Reality wurde in der Anforderungsanalyse ein Mixed-Methods-Ansatz mit Fokusgruppen (n = 40) und einer Online-Befragung (n = 311) gewählt. Die Ergebnisse zeigen, dass ein Großteil der Nutzer sich vorstellen kann, ein Reiseassistenzsystem zu nutzen, viele bei der Verwendung von Datenbrillen und Sprachinteraktion im öffentlichen Raum jedoch Bedenken haben. Als wichtigste Funktionen eines Reiseassistenzsystems werden die Unterstützung im Störungsfall, die Fußgängernavigation sowie die Versorgung mit Informationen zur Reisekette angesehen. Basierend auf den erhobenen Daten wurden Personas und Szenarien entworfen. Diese Werkzeuge ermöglichen es, dass sich die an der Entwicklung beteiligten Personen besser in den zukünftigen Nutzer des Reiseassistenzsystems sowie in den Nutzungskontext hineinversetzen und Gestaltungslösungen aus Nutzersicht beurteilt werden können. Praktische Relevanz: Intermodale Mobilitätsketten sowie die zunehmende Komplexität von Verkehrsknotenpunkten stellen Reisende vor die Herausforderung, unter Zeitdruck herauszufiltern, welche aus der Fülle der zur Verfügung stehenden Informationen für sie in der aktuellen Situation relevant sind. Dieser Beitrag analysiert, welche Informationen Reisende wann benötigen, mit dem Ziel, die Entwicklung von Assistenzsystemen zu unterstützen, die Informationen situations- und nutzergerecht zur Verfügung stellen und so die Beanspruchung beim Reisen reduzieren.

Supporting users in their daily activities, thus, making their lives more comfortable, has long been a goal for consumer-oriented systems development. With the rise of smart personal assistants (SPAs), however, we have reached a new milestone along the path towards this goal. These systems assist their owners by providing personalized and context-dependent information and service. Today's implementations reach from conversational agents, such as Siri, Cortana or Google Assistant, over chatbots, which are primarily text-based, to cognitive assistants, which assist according to a user's current cognitive or emotional state. However, although both research and practice proceed with full pace, recurring design elements of SPAs have not yet been investigated. We hence propose a pattern language for smart personal assistants to guide further empirical and design efforts. Therefore, we review existing information systems, computer science and human-computer interaction literature to find recurring design characteristics among 115 different assistants. The resulting pattern language contains 22 patterns that specify the interaction behavior and the intelligence of smart personal assistants.

The Hagelin M-209 was a mechanical encryption device used by the U.S. Army during World War 2 (WWII) and the Korean War, as well as by other armies and diplomatic services. The Hagelin M-209 has been the focus of extensive research by codebreaking agencies. Several ciphertext-only attacks have been published, but, those attacks are applicable only to the case of long cryptograms. In this article, the authors present a nested hill-climbing and simulated annealing algorithm for recovering the full key settings from ciphertext only, with ciphertexts as short as 500 letters, compared to a minimum of 750 to 1,250 letters with prior methods. With this method, the authors have solved the last problem of a public Hagelin M-209 challenge contest.

Currently, research on service science has emerged as its own discipline, where service systems are its basic unit of analysis. However, without a clearly defined modeling approach for service systems, analyzing a service system is challenging. We therefore propose a conceptual hypergraph-based modeling approach, which can be used to model services for both traditional goods-dominant businesses, as well as service-businesses. We define key elements of a service system while drawing upon hypergraph theory and present three modeling properties which are required to model a service systems graph (SSG). The focus of SSGs is to describe the relationships between the various resources, actors and activities, thus configuring a service system. It provides the foundation for computer graphic simulations and database applications of service business structure for future research.

Reproducible experiments are a major requirement for transparent, comparable and verifiable results in the field of human-robot interaction (HRI). Furthermore, a version-controlled and well-structured "ready to deploy" system setup of soft- and hard-ware for an HRI experiment opens up a range of innovative possibilities for interdisciplinary efforts as well as simplified participation of collaborators in the research community. However, making experiments reproducible is not a trivial task. It stems from the lack of agreed upon methodologies, tools and the inherent technical complexity. In this work we present our latest efforts in the context of an international and interdisciplinary research project to enable robotics researchers, software engineers, and social scientists to work together to reproduce a behavioral HRI experiment. The successful reproduction demonstrates that our tool chain approach meets the proposed requirements of the reproducibility problem. To the best of our knowledge, this is the first time an integrated systemic approach allowed an identical instantiation of a complete HRI experiment at geographically distributed locations.

Die digitale Transformation verändert gegenwärtig die Art und Weise, wie Arbeit erbracht und organisiert wird. Bestehende Geschäftsmodelle verlieren an Attraktivität, neue Geschäftsmodelle kommen hinzu. Zwei Trends sind dabei besonders signifikant: Die „Plattform-Ökonomie“, mit Crowdworking-Plattformen als einer ‚Spielart‘, die in den letzten Jahren starken Zulauf erfahren hat, und die „Sharing-Economy“. In diesem Beitrag zeigen wir am Beispiel der Crowdworking-Plattform Mila und ihres Kunden und 51-prozentigen Eigentümers Swisscom AG, wie Unternehmen die Crowd für Wertschöpfung einsetzen, ihren Kundensupport ausbauen und damit Vorteile für alle Beteiligten generieren können. Die Crowdworking-Plattform Mila verbindet in einem neuartigen Ansatz das Paradigma der Crowd, insbesondere die Nutzung einer Vielzahl von Leistungserbringern, mit den Prinzipien der Sharing-Economy, vor allem dem Einbezug der Kunden als Produzenten von Dienstleistungen. Basierend auf Experten-Tiefen-Interviews mit Verantwortlichen von Mila und Swisscom analysieren wir in diesem Beitrag dieses neuartige Arbeitssystem inklusive des Zusammenspiels aller Beteiligten und leiten daraus Handlungsempfehlungen für Unternehmen ab.

Crowdsourcing has evolved into a powerful new instrument for companies. In the last years, crowdworking platforms that manage work systems as intermediaries between crowdsourcers and crowd workers have increasingly been used. Nevertheless, they currently often manage rather simple work systems. Although they have the potential for managing more complex ones, there is still little knowledge how this can be done and what measures are necessary to do so. To explore this question in more detail, we investigate three seminal projects that Deutsche Bank completed with the crowdworking platform Jovoto and that aimed at exploring AI trends and developing concepts for the future of banking. We derive measures necessary for the successful management of complex work systems and provide a model as guidance for both companies and crowdworking platform operators. With our findings, we extend current knowledge in the realm of IS, organizational theory, and platform ecosystems.

Crowdsourcing has the potential to change the way how companies and other organizations are working currently. Numerous companies are already exploiting this new form of work organization and are utilising the “wisdom of crowds”. Crowdworking platforms as intermediaries that manage the work system including customer companies and crowd workers play an important role in this context. Nevertheless, they currently mostly manage rather simple work systems that process rather plain work. In this summary for the HICSS 2018 Doctoral Consortium, we depict our current work in progress that aims at investigating how such platforms could also manage more complex work systems – a question that is crucial for the future success of this business model. Using the case of Intel and the crowdworking platform Hyve, we investigate one successful approach to tackle this challenge, elaborate on our method used as well as the theoretical background and communicate our first, preliminary findings.

With the growth of the Social Web, a variety of new web-based services arose and changed the way users interact with the internet and consume information. One central phenomenon was and is tagging which allows to manage, organize and access information in social systems. Tagging helps to manage all kinds of resources, making their access much easier. The first type of social tagging systems were social bookmarking systems, i.e., platforms for storing and sharing bookmarks on the web rather than just in the browser. Meanwhile, (hash-)tagging is central in many other Social Media systems such as social networking sites and micro-blogging platforms. To allow for efficient information access, special algorithms have been developed to guide the user, to search for information and to rank the content based on tagging information contributed by the users.

The reproducibility and objective assessment of a robot's manipulation ability is a crucial topic in robotics. The definition of testing protocols and the automation of such test procedures is challenging. Most evaluation protocols in benchmarks and competitions include not completely standardized interactions of a human/referee and are furthermore influenced by partially subjective criteria across different research areas. A promising and more objective solution is to automate benchmarking protocols for a range of reproducible manipulation tasks. We present an approach that is simplified to the essential elements, in which most of the process and evaluation is automated. The proposed system has low price and effort requirements and allows researchers to compare their robots without placing them side by side. To allow a wide range of robots to be benchmarked all parts will be available open source. In our system, an object is positioned in front of the benchmarked robot by a mobile minirobot that localizes itself on a table according to the individual task's predefined positions. By automating most of the process we ensure that the object locations tested as well as the timings are reproducible and well documented. This approach fosters the objective comparability of robot performances.

Creativity is the generation of novel and useful ideas. Organizations, including universities and other research institutions, need to develop novel and useful products to satisfy constantly evolving customer needs. Furthermore, organizational procedures and processes develop over time, and continuous improvements in processes contribute to organizational efficiency. Thus, the development of novel and useful ideas in relation to products, procedures and services is mandated from many employees in modern organizations, including researchers and scientists. This creativity can take on many different forms, for example unconventional solutions to a wide variety of problems related to research, teaching and administration. Because many of these problems are comparable to that of workers in all kinds of jobs, I believe it is possible to draw on the rich knowledge in the field of organizational creativity to provide some insights into how to foster scientific creativity. The work of researchers and scientists is in many ways comparable to that of knowledge workers in other kinds of organizations: they are high-level employees who apply knowledge to do their work, oftentimes using creative thinking. A rich body of literature has dealt with creativity in these jobs where creativity is a core requirement, and has examined the organizational factors related to creativity. Before I summarize this research and highlight some important research findings concerning the rewards for creativity, the design of jobs, the processes leading to creativity, the organizational climate, and daily work events associated with creativity, I will disentangle different forms of creativity at work and describe a general model of creativity in the context of work.

For localization and mapping of indoor environments through WiFi signals, locations are often represented as likelihoods of the received signal strength indicator. In this work we compare various measures of distance between such likelihoods in combination with different methods for estimation and representation. In particular, we show that among the considered distance measures the Earth Mover's Distance seems the most beneficial for the localization task. Combined with kernel density estimation we were able to retain the topological structure of rooms in a real-world office scenario.

Quantifying the Influences on Probabilistic Wind Power Forecasts. Schreiber, Jens; Sick, Bernhard. In International Conference on Power and Renewable Energy, Vol. 3, p. 6. 2018.
- [ Abstract ]
- [ BibSonomy-Post ]
In recent years, probabilistic forecasts techniques were proposed in research as well as in applications to integrate volatile renewable energy resources into the electrical grid. These techniques allow decision makers to take the uncertainty of the prediction into account and, therefore, to devise optimal decisions, e.g., related to costs and risks in the electrical grid. However, it was yet not studied how the input, such as numerical weather predictions, affects the model output of forecasting models in detail. Therefore, we examine the potential influences with techniques from the field of sensitivity analysis on three different black-box models to obtain insights into differences and similarities of these probabilistic models. The analysis shows a considerable number of potential influences in those models depending on, e.g., the predicted probability and the type of model. These effects motivate the need to take various influences into account when models are tested, analyzed, or compared. Nevertheless, results of the sensitivity analysis will allow us to select a model with advantages in the practical application.

Humans will soon need to adapt to a collaborative setting in which technology becomes a smart collaboration partner that works with a group to achieve its goals. It is therefore time for collaboration researchers to explore the vast opportunities afforded by smart technology and to test its utility for enhancing team processes and outcomes. In this paper, we take a long view on the implications of smart technology for collaboration process design, and propose a research agenda for the next decade of collaboration research. We create a reference model to frame the research agenda.

Chatbots are becoming a ubiquitous trend in many fields such as medicine, product and service industry, and education. Chatbots are computer programs used to conduct auditory or textual conversations. A growing body of evidence suggests that these programs have the potential to change the way students learn and search for information. Especially in large-scale learning scenarios with more than 100 students per lecturer, chatbots are able to solve the problem of individual student support. However, until now, there has been no systematic, structured overview of their use in education. The aim of this paper is therefore to conduct a systematic literature review based on a multi-perspective framework, from which we have derived initial search questions, synthesized past research, and highlighted future research directions. We reviewed titles and abstracts of 1405 articles drawn from management, education, information systems, and psychology literature before examining and individually coding a relevant subset of 80 articles. The results show that chatbots are in the very beginning of entering education. Few studies suggest the potential of chatbots for improving learning processes and outcomes. Nevertheless, past research has revealed that the effectiveness of chatbots in education is complex and depends on a variety of factors. With our literature review, we make two principal contributions: first, we structure and synthesize past research by using an input-process-output framework, and secondly, we use the framework to highlight research gaps for guiding future research in that area.

Pedestrians globally comprise 22 % of all road traffic deaths in 2013. Various approaches for reducing accident numbers have already been introduced and are still being researched. Most of these approaches have specific limitations, like requiring line of sight. To overcome these limitations, we propose the Wireless Seat Belt (WSB), a smartphone-based collision avoidance system for pedestrians. Unlike other systems, the WSB uses context information, obtained from a pedestrian's smartphone, not only as additional information but also for using the information to improve the collision detection accuracy. The WSB introduces independent, individual modules for recognizing the pedestrian's direction, position, and speed. We first evaluate the influence of the measurement errors of each module on the missed alarm probability in a typical urban collision scenario using a simulator. Then, the impact of using the pedestrian's context to decrease the missed alarm probability is evaluated. The evaluation is done using the example of a curb detection module. The curb detection is used to infer that the pedestrian has stepped onto the street to correct the pedestrian's position. The results show a decrease of the missed alarm probability by 46.5 % in the scenario considered.

Research Question According to effort-recovery theory (Meijman & Mulder, 1998), employees need recovery from work-related effort. However, work stressors influence employees even beyond their workplaces. Furthermore, the rapid development of new technologies leads to growth in work-related technology use after hours. Consequently, the opportunities for employee recovery are reduced. In order to shed light on the supplemental work behaviour through technology use after hours, we examine its antecedents and consequences. Study Design We used a shortitudinal panel design. Data from 73 full-time workers in Germany were collected online on Friday after work, at the weekend, and on Monday morning before going to work. Results Serial mediation analysis supported the hypotheses. Results indicate that work stressors influence work-related technology use after hours, which, in turn, hinders psychological detachment from work and impairs sleep quality. Limitations Future research should shed more light on the long-term consequences of work-related technology use after hours and systematically take personal and situational factors into account. Implications Our findings emphasize the importance of the need for developing strategies to prevent and handle work stressors and supplemental work after hours. Contribution This study contributes to stress and recovery research and the emerging research on work-related technology use after hours by examining its antecedents and consequences.

Der Beitrag beschreibt die Gestaltung, prototypische Umsetzung und Evaluation eines Reiseassistenzsystems mit Datenbrillen für intermodale Reiseketten im öffentlichen Verkehr. Die Grundlage bildet ein Szenario, welches die Reisekette ab der eigenen Haustür bis zum Gate an einem Flughafen darstellt und mehrere Verkehrsmittelwechsel sowie Fußwege beinhaltet. Die Datenbrille liefert dem Nutzer reiserelevante Informationen, die situations- und nutzergerecht dargestellt werden sollten. Der szenariobasierte Prototyp wurde für die Durchsichtdatenbrille Epson Moverio BT-200 entwickelt und in einer Laborstudie mit zwölf Probanden formativ evaluiert. Die Ergebnisse zeigen, dass die Nutzung eines Reiseassistenzsystems mit Datenbrillen, insbesondere in unbekannter Umgebung, als hilfreich erachtet wird.

Kademlia is a decentralized overlay network, up to now mainly used for highly scalable file sharing applications. Due to its distributed nature, it is free from single points of failure. Communication can happen over redundant network paths, which makes information distribution with Kademlia resilient against failing nodes and attacks. In this paper, we simulate Kademlia networks with varying parameters and analyze the number of node-disjoint paths. With our results, we show the influence of these parameters on the network connectivity and, therefore, the resilience against failing nodes and communication channels.
Evaluation eines Führungskräfte-Trainings zur effektiven Kommunikation von IKT-Erreichbarkeitserwartungen. Heissler, Clara; Ohly, Sandra. In Proceedings of the 10.

Fragestellung. Die Zufriedenheit mit der beruflichen Kommunikation mit Hilfe von Informations- und Kommunikationstechnologien (IKT) außerhalb der Arbeitszeiten hängt damit zusammen, ob die eigene Führungskraft ihre Erwartungen bezüglich der erweiterten Erreichbarkeit klar kommuniziert. Häufig ist Führungskräften der eigene Einfluss auf das Nutzungsverhalten der Mitarbeiter nicht bewusst und eine Klärung der Erwartungen findet nur selten statt. Diese Studie verfolgt das Ziel, ein Führungskräfte-Training zur effektiven Kommunikation von Erreichbarkeitserwartungen zu konzipieren und durch eine Befragung der direkt unterstellten Mitarbeiter zu evaluieren. Untersuchungsdesign. Das fünfstündige Präsenz-Training unterstützt Führungskräfte dabei, ihre eigene Rolle für das IKT-Nutzungsverhalten ihrer Mitarbeiter kennenzulernen, Erreichbarkeitserwartungen zu definieren, und diese verständlich an ihre Mitarbeiter zu kommunizieren. Ergebnisse. Die Datenerhebung erfolgt mittels Pretest-Posttest Design in zwei Unternehmen (T1 ca. 1 Woche vor und T2 ca. 6 Wochen nach dem Training), wobei zu beiden Zeitpunkten die direkt unterstellten Mitarbeiter der Teilnehmer befragt werden. Die Datenerhebung endet im Sommer 2017. Es wird erwartet, dass die Führungskräfte nach dem Training ihre Erwartungen an ihre Mitarbeiter kommunizieren. Diese können dadurch besser einschätzen, was von ihnen erwartet wird und sind zufriedener mit der beruflichen IKT-Kommunikation. Limitationen. Die Teilnahme am Training íst freiwillig und es liegt keine Kontrollgruppe vor. Daher ist die interne Validität eingeschränkt. Theoretische/Praktische Implikationen. Die Studie verdeutlicht den Einfluss der Führungskraft für den Umgang mit IKT im beruflichen Kontext. Das Training stellt eine praxisnahe Möglichkeit dar, Führungskräfte im Umgang mit IKT zu sensibilisieren und in ihrer Aufgabe der gesundheitsförderlichen Führung zu stärken. Relevanz/Beitrag. Insbesondere im Kontext der beruflichen IKT-Nutzung liegen bisher nur wenige Trainingskonzepte vor, die zumeist auf individuelle Einflussmöglichkeiten fokussieren.

Das Ziel des Forschungsprojektes Robotair war die Entwicklung und Evaluation eines prototypischen, kostengünstigen Boden-Luft-Servicerobotersystems für die Detektion und Ortung von Druckluftleckagen zwecks nachhaltiger Ressourcen- und Energienutzung sowie für die Erfassung von Arbeitsumgebungsfaktoren zur Sicherstellung gesunder Arbeitsbedingungen und Steigerung der Produktivität. Durch die regelmäßige Inspektion von Druckluftanlagen werden frühzeitig Leckagen entdeckt, dadurch Verluste und der Primärenergieeinsatz verringert, was sich wiederum positiv auf den CO2-Ausstoß und das Klima auswirkt. Aufgrund schlechter räumlicher Erreichbarkeit, geringer Produktrelevanz und geringer Energiekosten wurde dies bisher oft vernachlässigt. Auch in der Gebäudetechnik sollten durch roboterbasierte, multimodale Kartierung der klimatischen Lokalsituation Einsparmöglichkeiten identifiziert und realisiert werden und gleichzeitig ein Beitrag zur Erfassung und Verbesserung der Arbeitsumgebungsbedingungen geleistet werden. In verschiedenen Studien wurden die wirtschaftliche Signifikanz und der große adressierbare Markt dokumentiert, wie auch eine Potentialabschätzung der Volkswagen AG und eine Kostenabschätzung der Forschungspartner auf Basis der EFFIROB-Systematik zeigte. Innerhalb des Forschungsprojektes wurden Anforderungen erhoben und ein Systemprototyp erstellt, dessen robuste Funktionsweise und Gebrauchstauglichkeit im Labor und in Feldstudien in der Automobilindustrie evaluiert wurde.

Flugroboter werden immer populärer und in immer mehr Alltagsszenarien eingesetzt. Dies forciert den Bedarf nach intuitiven und gebrauchstauglichen Steuerungen. Wir demonstrieren eine entworfene natürliche Benutzungsschnittstelle zur Steuerung eines Flugroboters, die in einer Benutzerstudie mit einer traditionellen Steuerung verglichen wurde. Hierfür verwenden wir ein bewegungserkennendes Armband und eine Microsoft HoloLens für die visuelle und auditive Ausgabe von Rückmeldungen und die Steuerung des Flugroboters über die Kopfneigung des Benutzers. Weitere Informationen zu der entworfenen natürlichen Benutzungsschnittstelle, sowie Ergebnisse der Benutzerstudie sind im dazugehörigen Langbeitrag (Herrmann \& Schmidt, 2017) beschrieben.

The information about a person's activity, as a special type of contextual information, can be used for a multitude of applications. Thus, activity detection is a focus in research. For activity detection, usually measured sensor data are processed and matched to known activities. Unfortunately, measured sensor data can be inconsistent for the same activity. Depending on the device orientation and in which direction of compass the user is heading (while carrying out an activity) the sensor data changes. As a result, expected values on one sensor axis appear on another one and it is challenging for a pre-generated activity detection model to match the sensor data to the activity. However, the intuitive solution seems to be easy: focus on the user. Regardless of the device orientation or the cardinal direction, the activity never change for the user. In this paper, we present an approach to focus on the user in activity detection. We convert sensor data into a representation relative to the user. Thus, the sensor data stay consistent regardless of the device orientation or the cardinal direction. We show that by using the focus on the user approach the detection rates increase up to 21.7%. Also, the detection is more reliable (lower standard deviation). We prove the reliable activity detection for different device orientations, cardinal directions, types of algorithms, sensor sets, activities, and sensor positions.
An Activity History based Approach for Recognizing the Mode of Transportation. Jahn, Andreas; Kroll, Dennis; Lau, Sian Lun; David, Klaus. In Proceedings of the IEEE Conference on Open Systems (ICOS), pp. 1–5. IEEE, Miri, Sarawak, Malaysia, 2017.

By understanding a person's context, smart assistant systems aim to simplify and automate tasks. One type of useful context information is the mode of transportation. Commonly, the mode of transportation is recognized by analyzing raw sensor data of mobile devices, such as a smartphone. However, fine-grained sampling and collecting sensor data at high frequency to analyze raw sensor data is also conducted by activity recognition systems. These systems have been shown to accurately recognize activities such as sitting, standing, or walking. This means several systems analyze raw data for their needs. In our opinion, this doubled use of resources should be avoided. In this paper, we propose an approach, which avoids doubled raw sensor data analysis by taking advantage of the already available information of a person's activity. As a hypothesis, the approach assumes that observed activity sequences can lead to the mode of transportation. Thus, we aim to map activity sequences to modes of transportation. Applying the proposed approach, we show that the three different modes of transportation car, tram, and bus are recognized with an accuracy of up to 97%.

Distributed Hash Tables (DHT) are a common architecture for decentralized data management. However, currently existing DHTs allow every participant to access any index. To build secure applications, we need to control this access. In this paper, we present k-rAC, a fine-grained access control for DHTs. It allows to specify and enforce different access rights for each individual data item in the presence of attackers and up to $$k$$ subverted participants. Our approach can be tailored towards different thread levels and usage scenarios by adapting k and by choosing one of three authentication mechanisms that we provide.

In diesem Beitrag wird die Realisierung einer Versuchsumgebung beschrieben, die bei einem guten Verhältnis von Kosten, Aufwand und Genauigkeit eine Indoorlokalisierung mit Bluetooth-Low-Energy-Beacons ermöglicht. Es wird eine prototypische Indoornavigation mit einer Durchsichtdatenbrille vorgestellt, die dem Nutzer kontaktanaloge Navigationsanweisungen in 3-D entlang seines Zielpfades einblendet. Eine Nutzerevaluation zeigt, dass insbesondere die händefreie Interaktion als nützlich angesehen wird und die Gestaltung einer Augmented-Reality-Indoornavigation Ungenauigkeiten bei der Lokalisierung besonders berücksichtigen sollte, wenn relativ enge Wege genutzt werden.

While the rise of context aware apps remains, the question arises whether algorithms for context processing can be applied to any smartphone and for any user. In this paper, we propose to test context algorithms for each specific smartphone, user, and situation to which a context algorithm is applied. Towards this, we present our framework which automatically measures all relevant information about an app's runtime properties, i.e. resource utilization and the time taken to process sensor values by a context algorithm. Both information can be automatically returned to the app developers in order to improve the app. We implemented the framework on Android and tested it using the example of a state-of-the-art context algorithm to find out whether our test smartphone is capable of running the context algorithm without delays and deadlocks.

Start-ups often face the challenge of a shortage of capital, the so-called funding gap, which can be overcome by raising small amounts of money from a large number of individuals. As crowdfunding suffers from a continuous rise in failure rates, the aim of this article is to contribute to the research concerning success factors in reward-based crowdfunding campaigns by focusing on signaling theory. Based on data retrieved from the crowdfunding platform Kickstarter, our results indicate that social ties, investment preparation and presentation, the supply of multiple rewards as well as endeavors to communicate and interact with the crowd positively influence the probability of success of a reward-based crowdfunding campaign. In contrast, the funding goal, a campaign’s runtime and the estimated time of delivery for the rewards have a negative impact on the successful completion of a campaign.

When evaluating the cause of one's popularity on Twitter, one thing is considered to be the main driver: Many tweets. There is debate about the kind of tweet one should publish, but little beyond tweets. Of particular interest is the information provided by each Twitter user's profile page. One of the features are the given names on those profiles. Studies on psychology and economics identified correlations of the first name to, e.g., one's school marks or chances of getting a job interview in the US. Therefore, we are interested in the influence of those profile information on the follower count. We addressed this question by analyzing the profiles of about 6 Million Twitter users. All profiles are separated into three groups: Users that have a first name, English words, or neither of both in their name field. The assumption is that names and words influence the discoverability of a user and subsequently his/her follower count. We propose a classifier that labels users who will increase their follower count within a month by applying different models based on the user's group. The classifiers are evaluated with the area under the receiver operator curve score and achieves a score above 0.800.

According to conservation of resources model and control theory, routinized task behavior that develops through repeated execution under stable circumstances helps employees to deal with demanding aspects of their jobs. In two studies, we investigated whether routinized task behavior predicts momentary levels of energy. In the first study, 328 employees rated their level of routinization of five work tasks and subsequently provided information on their daily working on these tasks and energy twice a day on five consecutive workdays. Multilevel analyses reveal that employees experience higher levels of energy after they were working on a highly routinized task. In the second study, 32 employees provided ratings of their current routinized task behavior and energy three times a day for three consecutive workdays (in total 285 data points). Routinized task behavior at one point in time predicted energy at the next point in time when controlling for initial levels of energy. These results indicate that routinized task behavior is an effective way of managing energy at work, and that a microanalysis of task behaviors offers valuable insights.

The development of novel and useful ideas is a process that can be described in multiple steps, including information gathering, generating ideas and evaluating ideas. We evaluated a university course that was developed based on design thinking principles which employ similar steps. Our results show that the course was not effective in enhancing students' creative self-efficacy, the belief that they are able to generate novel and useful ideas. Comparison to previous training approaches lead to conclusions on how to improve the course, and to implications for future research.

Sprachsteuerungen halten verstärkt Einzug in den Alltag der Menschen, wenn diese mit technischen Geräten interagieren. Die Frage nach der Gestaltung von Mensch-Maschine-Schnittstellen stellt sich auch in der Automatisierungstechnik. Um die Gebrauchstauglichkeit und kontextabhängige Akzeptanz sprachbasierter Smartphone-Steuerung mittels Google-Now in Bezug auf Nutzer unterschiedlicher Alterskohorten zu evaluieren, wurden im Rahmen einer Laborstudie mit zwei unabhängigen Stichproben die Effektivität und die Effizienz sprachbasierter Smartphone-Interaktion mit dem heute üblichen Interaktionsmuster der virtuellen Touchscreen-Tastatur verglichen. Außerdem wurden die empfundene Einfachheit der Nutzung sowie die kontextabhängige Nutzungsbereitschaft der beiden Eingabemodalitäten evaluiert. Die Studie zeigt, dass beide Eingabemodalitäten sowohl von jüngeren als auch von älteren Nutzern zur Erledigung von navigationsbezogenen Aufgaben genutzt werden können. Jedoch treten im Hinblick auf Effektivität (Häufigkeit von Fehleingaben) und Effizienz (Bearbeitungsdauer) der Aufgabenerfüllung signifikante Unterschiede sowohl zwischen den Eingabemodalitäten als auch zwischen den beiden Alterskohorten auf.

Bei der Interaktion mit den Fingern auf der glatten Fläche eines berührempfindlichen Bildschirms fehlt gegenüber den mechanischen Eingabegeräten die natürliche, über den haptischen Sinn vermittelte Rückmeldung. Diese Rückmeldung wird vielfach künstlich in Form von Vibrationen erzeugt. Es gibt noch keine ausreichenden und systematischen Gestaltungsempfehlungen für die haptische Rückmeldung bei der Nutzung von Touchscreens. Bisherige experimentelle Untersuchun-gen beziehen sich nur auf einzelne, eng umgrenzte Fragestellungen und geben auch keine Hinweise für diesen speziellen Anwendungsfall. Im Projekt InterHapt wurde deshalb die menschliche Wahrnehmung bezüglich haptischer Rückmeldung an Touchscreens untersucht, um Gestaltungsempfehlungen abzuleiten. Der Stand des Wissens über haptische Wahrnehmung, die technischen Möglichkeiten zur Erzeugung haptisch wahrnehmbarer Rückmeldung und die Formen und Einsatzgebiete von Touchscreens wurden erhoben. In einer Nutzerbefragung wurden Umgang und Erfahrung mit Touch-screens und haptischer Rückmeldung bestimmt sowie Handhaltung und benutze Finger ermittelt. In Experimenten wurde fehlendes Wissen über haptische Wahrnehmung ergänzt und in einem Abschlussexperiment die optimale Rückmeldung für unterschiedliche Interaktionselemente bestimmt. Kontaktzeiten und aufgewendete Kräfte, die Wahrnehmungsgrenzen, die Reaktionszeiten für unterschiedliche Formen von Stimuli, die subjektive Einschätzung unterschiedlicher Vibrationsfrequenzen und -amplituden und die als angenehm bewerteten und bevorzugten Kombinationen für unterschiedliche, auf Touchscreens mögliche Interaktionsformen sind damit bekannt. Diese Ergebnisse können zur Implementierung effektiver, effizienter und als angenehm empfundener haptischer Rückmeldung verwendet werden.

Tactons are structured tactile messages and used to transmit information to users via the tactile sense. In recent studies, tactons were tested under various conditions and their benefits were demonstrated, while tactons were mostly applied on a non-interacting part of participants’ body. In future applications, e. g. in touch screen interaction, the device itself will probably generate the tactile feedback providing it to the user’s interacting finger. Therefore, common parameters (i. e., frequency, amplitude, rhythm, roughness, waveform, and duration) in such a setting were examined and tested for discriminability in order to derive guidelines for tacton design in touch screen interaction. 51 participants took part in the experiment, which consisted of 98 randomized tasks. In each task, participants were presented two vibration signals via a touch screen and had to decide, whether signals were identical or different. 87 tasks comprised a comparison between different signals, while only one parameter was altered in a single comparison, and 11 control pair signals were identical. The overall recognition rate was 0.69 ± 0.15 but various combinations showed recognition rates above 90%. It became clear that some parameters are more suitable in tacton design than others. Frequency and roughness achieved the best results, involving all paired comparisons which were correctly distinguished by each participant. Distinguishable levels of parameters and design recommendations were derived from the experiment, and considerations about future tacton design are presented.

The recognition of human emotions using physiological signals such as Electrodermal Activity (EDA), Electrocardiogram (ECG) or Electromyography (EMG), has been extensively researched in the past attracting a lot of interest during the last few decades. Although showing a relatively satisfactory performance under lab conditions, Emotion Recognition (ER) systems using physiological signals are not widely used in real-world scenarios. One important fact is that, in the real world, physiological signals may be influenced by human movement and therefore, they cannot be used as a unique indicative of emotions. In this paper, we investigate the influence of human movement on ER using physiological signals. We compare different measures of emotion before and after a test person has performed some physical activity (e.g. walking, going upstairs). We discuss the main differences between recognizing emotions in the lab and the real world and provide new insights into the development of ER systems in real-world scenarios.

Kontaktzeiten und aufgewendete Kräfte, die Wahrnehmungsgrenzen, die Reaktionszeiten für unterschiedliche Formen von Stimuli, die subjektive Einschätzung unterschiedlicher Vibrationsfrequenzen und -amplituden und die als angenehm bewerteten und bevorzugten Kombinationen für unterschiedliche, auf Touchscreens mögliche Interaktionsformen sind damit bekannt. Diese Ergebnisse können zur Implementierung effektiver, effizienter und als angenehm empfundener haptischer Rückmeldung verwendet werden.

Social bookmarking systems have established themselves as an important part in today’s web. In such systems, tag recommender systems support users during the posting of a resource by suggesting suitable tags. Tag recommender algorithms have often been evaluated in offline benchmarking experiments. Yet, the particular setup of such experiments has rarely been analyzed. In particular, since the recommendation quality usually suffers from difficulties like the sparsity of the data or the cold start problem for new resources or users, datasets have often been pruned to so-called cores (specific subsets of the original datasets) – however without much consideration of the implications on the benchmarking results. In this paper, we generalize the notion of a core by introducing the new notion of a set-core – which is independent of any graph structure – to overcome a structural drawback in the previous constructions of cores on tagging data. We show that problems caused by some types of cores can be eliminated using setcores. Further, we present a thorough analysis of tag recommender benchmarking setups using cores. To that end, we conduct a large-scale experiment on four real-world datasets in which we analyze the influence of different cores on the evaluation of recommendation algorithms. We can show that the results of the comparison of different recommendation approaches depends on the selection of core type and level. For the benchmarking of tag recommender algorithms, our results suggest that the evaluation must be set up more carefully and should not be based on one arbitrarily chosen core type and level.

Social tagging systems have established themselves as an important part in today’s web and have attracted the interest of our research community in a variety of investigations. Henceforth, several aspects of social tagging systems have been discussed and assumptions have emerged on which our community builds their work. Yet, testing such assumptions has been difficult due to the absence of suitable usage data in the past. In this work, we thoroughly investigate and evaluate four aspects about tagging systems, covering social interaction, retrieval of posted resources, the importance of the three different types of entities, users, resources, and tags, as well as connections between these entities’ popularity in posted and in requested content. For that purpose, we examine live server log data gathered from the real-world, public social tagging system BibSonomy. Our empirical results paint a mixed picture about the four aspects. While for some, typical assumptions hold to a certain extent, other aspects need to be reflected in a very critical light. Our observations have implications for the understanding of social tagging systems, and the way they are used on the web. We make the dataset used in this work available to other researchers.

Für ein Servicerobotiksystem, welches teilautonom Arbeitsumgebungsfaktoren aufzeichnet sowie Ultraschall- und Thermografiemessungen durchführt, wurde ein mobiler Leitstand konzipiert und realisiert. Der Leitstand besteht aus einem mobilen verstellbaren Montage- und Bildschirmarbeitsplatz für die praktische Vorbereitung, Planung, Überwachung und Dokumentation des Robotereinsatzes sowie einer Datenbrille für die Teleoperation eines Flugroboters. Um die Gebrauchstauglichkeit der Benutzungsschnittstelle des Bildschirmarbeitsplatzes zu evaluieren, wurde eine Untersuchung mit Anwendern in der Produktionsumgebung eines Automobilherstellers durchgeführt. Um die Gebrauchstauglichkeit der Assistenzfunktionen bei der Teleoperation von Flugrobotern zu evaluieren, wurde des Weiteren eine Untersuchung zur Darstellung von Warnmeldungen in Datenbrillen bei einer realen Flugaufgabe durchgeführt. Die Ergebnisse zeigen Verbesserungsmöglichkeiten für die Gestaltung der Benutzungsschnittstelle auf und geben Gestaltungshinweise für die Darstellung von Warnmeldungen in Datenbrillen.

Der technologische Fortschritt ermöglicht die Verwendung einer Freihandgestensteuerung in alltäglichen und industriellen Szenarien. Eine neue Möglichkeit Freihandgesten zu erkennen, ist die Verwendung eines bewegungserkennenden Armbandes. Trotz kritischer Anmerkungen hinsichtlich der Gebrauchstauglichkeit von Gesten versprechen sich Forscher von der Verwendung eines Armbandes zur Gestenerkennung u. a. groe Potentiale in der Mensch-Roboter-Interaktion. Grund hierfür ist die aus Anwendersicht einfache und intuitive Verwendung eines Armbandes im Gegensatz zu anderen Verfahren zur Gestenerkennung und die dadurch mögliche Steigerung der Gebrauchstauglichkeit. Inwieweit die Verwendung eines bewegungserkennenden Armbandes für die gestische Teleoperation eines Bodenroboters geeignet ist, wird anhand eines Versuchs mit 23 Teilnehmern ermittelt. Hierfür wurde eine Gestensprache für die Navigation eines Bodenroboters entworfen, bei der die Charakteristiken einer Virtual- oder Augmented-Reality-gestützten Teleoperation berüucksichtigt wurden. Die Erkennung der Gesten wurde mittels eines Armbandes unter Verwendung integrierter Ober flächenelektromyographie (OEMG) und Accelerometer realisiert. Die Ergebnisse zeigen signifikant schlechtere Eigenschaften hinsichtlich Gestenerkennungsraten und Gestenausführungszeiten gegenüber einer marker- und kamerabasierten Lösung. Insbesondere die mit dem Armband realisierte Methode des OEMG zeigt in der Kombination mit der entworfenen Gestensprache deutliche Defizite hinsichtlich der Erkennung der Gesten. Allerdings können hinsichtlich der Intuitivität positive Aspekte aufgezeigt werden.

Flugroboter werden immer mehr im industriellen Bereich eingesetzt. Einsatzfelder sind dabei z. B. Inspektionen von schwer zugänglichen Bereichen oder die automatisierte Durchführung von Inventuren in Großlagern. Für die Steuerung solcher Flugroboter steht zumeist eine klassische Remote Control (RC) zur Verfügung, mit der die Freiheitsgrade des Flugroboters über zwei Joysticks gesteuert werden können. Eine solche Steuerung neben der eigentlichen Arbeitsaufgabe zu beherrschen ist für ungeübte Personen nahezu unmöglich. Auf der anderen Seite bietet eine Gestensteuerung eine intuitive und leicht erlernbare Möglichkeit Roboter zu steuern, die natürliche menschliche Kommunikations- und Handlungsweisen berücksichtigt. Daher wurde eine auf Gesten basierende Steuerung für Flugroboter entworfen, die als Ersatz für eine RC dienen kann. Dieser Beitrag stellt das methodische Vorgehen und die Ergebnisse einer nutzerbasierten Evaluation dar, in der Probanden mit einer RC und der entworfenen Gestensteuerung einfache Flugaufgaben lösen sollten. Ziel war insbesondere die Beurteilung der Gebrauchstauglichkeit und der Intuitivität der beiden Steuerungen.

The information of a person's activity can be used for a multitude of application. Thus, the activity recognition and the improvement of the activity recognition performance is a focus of research. Unfortunately, activities similar to each other are still likely to be mixed up during the activity recognition, resulting in a decrease in activity recognition performance. We propose a lightweight method to improve the recognition performance. By reevaluating recognized activities, we group similar activities to a new activity. We refer the created activity as grouped activity. We evaluate our method with an activity-set of seven activities and compare the results with two common approaches: the average recognition performance of the individual activities and the recognition performance using a generalized activity. We show an F-Measure improvement of up to 6.6 % by using the grouped activity.

- [ Abstract ]
- [ BibSonomy-Post ]
Benachrichtigungen auf mobilen Endgeräten sind ein Auslöser für die Ablenkung der visuellen Aufmerksamkeit weg von einer aktuell bearbeiteten Aufgabe hin zum Endgerät. Die zunehmende Verbreitung von Smartwatches, die von Herstellern als weniger ablenkend als Smartphones beworben werden und mittels Benachrichtigungen als zentraler Interface-Komponente agieren, lässt die Frage aufkommen, ob Benachrichtigungen auf Smartwatches eine geringere visuelle Ablenkung verursachen als Benachrichtigungen auf Smartphones und worin die Unterschiede bestehen. Dieser Beitrag beschreibt eine empirische Untersuchung mit 40 Probanden, die in vier Doppelaufgabensituationen jeweils hauptsächlich die gleiche Konzentrationsaufgabe zu bearbeiten hatten und nebenbei 12 eingehende Benachrichtigungen lesen und sich bestimmte Informationen merken sollten. Die unabhängigen Variablen waren das Endgerät (Smartphone oder Smartwatch) und die Platzierung des Endgeräts (natürliche oder auf Stativ fixiert). Es wurden objektive Leistungsparameter in der Haupt- und Nebenaufgabe sowie subjektive Parameter, wie die wahrgenommene Ablenkungswirkung der Nebenaufgabe, die Konzentrationsfähigkeit auf die Hauptaufgabe und die wahrgenommene Beanspruchung der Doppelaufgabe erhoben. Auch wurden Blickbewegungen erfasst. Die Erkenntnis dieser Studie ist, dass die Smartwatch-Interaktion im Gegensatz zur Smartphone-Interaktion Vorteile aufweist. Die Leistung in der Hauptaufgabe wurde signifikant weniger negativ beeinflusst. Ebenso wurde sie weniger beanspruchend und weniger ablenkend wahrgenommen.

Cryptanalysis of the Columnar Transposition Cipher with Long Keys. Lasry, George; Kopal, Nils; Wacker, Arno. In Cryptologia, pp. 1–25. 2016.

The classical columnar transposition cipher was the most popular type of transposition cipher. It was in use mainly during the second half of the nineteenth century and the first half of the twentieth century. It also served as a building block for more complex ciphers, such as the ADFGVX cipher and the double transposition cipher. Pen-and-paper as well as computerized methods for the cryptanalysis of the columnar transposition cipher have been published, but those apply mainly to the easier cases of short keys and complete transposition rectangles. In this article, a novel approach for the cryptanalysis of the columnar transposition cipher (when used with long keys) is presented. It is based on a two-phase hill climbing algorithm, a two-dimensional fitness score, and special transformations on key segments. This ciphertext-only method allows for the recovery of transposition keys with up to 1,000 elements, and up to 120 elements for worst case transposition rectangles.

Chaocipher is a manual encryption method designed by John F. Byrne in 1918. Until he passed away in 1960, Byrne fervently believed that his cipher system was unbreakable, regardless of the amount of material available to a cryptanalyst. For several decades, he tried (unsuccessfully), to propose the Chaocipher to government agencies. In 1953, he exposed his Chaocipher in his autobiography, Silent Years, providing several examples of texts encrypted with Chaocipher as challenges, but without divulging the inner workings of the cipher. Those were made public only in 2010, when Byrne’s family donated the entire corpus of Chaocipher papers to the National Cryptologic Museum (NCM) in Fort Meade. A known-plaintext method for recovering the key settings, given sufficient matching plaintext and ciphertext, was published in 2010. However, to date, no method for the cryptanalysis of a single ciphertext-only Chaocipher message has been proposed, nor for the cryptanalysis of short messages “in-depth,” i.e., multiple messages generated with the same initial key settings. In this article, the authors present a new hillclimbing algorithm for a ciphertext-only cryptanalysis of Chaocipher in-depth messages. This algorithm is based on a “divide-and-conquer” approach and the use of the Index of Coincidence. It takes advantage of a major weakness in the design of the cipher. This previously unknown weakness may have been the reason why William F. Friedman, the inventor of the Index of Coincidence, rejected Byrne’s offer for the use of Chaocipher by the U.S. government. Additionally, the authors present a known-plaintext attack for short in-depth messages, as well as the solution for Lou Kruh’s and Cipher Deavours’s alternate Exhibit 5, also known as “Exhibit 6.” Finally, the authors reevaluate the security of the Chaocipher in view of those findings, with the conclusion that in its classic form, as designed by Byrne, the Chaocipher was a relatively weak cipher, despite Byrne’s rather strong assertions to the contrary.

In this paper, we present an empirical study with children at the age of 4 and 5 years to reveal whether they engage with a robot in an interaction. For our analysis, we developed a score assessing the interaction level. It consists of emotional involvement, engagement and independence of the child in the interaction. For the interaction, an autonomous system was equipped with a designed dialogic structure. It consisted of a repertoire of (pre-recorded) interaction protocols that a robot can apply in an interaction. The results from the evaluation suggest that the implementation was successful as most of the studied children engaged in the interaction with the robot. The results also reveal some gender differences. The long-term aim of the study is to develop an autonomous system that can be applied in an interaction with young children.

Much attention has been given to the task of gender inference of Twitter users. Although names are strong gender indicators, the names of Twitter users are rarely used as a feature; probably due to the high number of ill-formed names, which cannot be found in any name dictionary. Instead of relying solely on a name database, we propose a novel name classifier. Our approach extracts characteristics from the user names and uses those in order to assign the names to a gender. This enables us to classify international first names as well as ill-formed names.

Um Nutzern von Touchscreens das gewohnte Gefühl von mechanischen Tasten wiederzugeben, können künstlich erzeugte haptische Rückmeldungen verwendet werden. Damit eine Touchscreen-Oberfläche mit Hilfe von Aktoren angeregt werden kann, müssen diese sowohl dem Eigengewicht des Touchscreens als auch den aufgebrachten Fingerkräften eines Nutzers entgegenwirken. Für letztere wurden typische Werte auf einer stationären Touchscreen-Oberfläche empirisch bestimmt. Die Messung der Fingerkräfte beim mehrmaligen Drücken einer virtuellen Taste lieferte unter 48 Versuchsteilnehmern eine durchschnittliche Finger-kraft von 5,02 N ± 2,56 N und eine maximale Fingerkraft von 12,73 N. Darüber hinaus konnten keine signifikanten Unterschiede der typischen Fingerkräfte in Bezug auf das Alter und das Geschlecht ermittelt werden.

Touchscreens werden zunehmend in Geräten des Arbeitsalltags eingesetzt, wobei das Gefühl konventioneller Tasten verloren geht. Für die Entwicklung von Gestaltungsempfehlungen einer künstlich generierten haptischen Rückmeldung von Touchscreens wurde die präferierte Kombination von Frequenz und Amplitude einer Vibration als Rückmeldung ermittelt. Mit einem zweistufigen Versuchsdesign wurde zunächst die bevorzugte Frequenz bei konstanter Amplitude und schließlich die präferierte Amplitude bei dieser Frequenz unter 23 Teilnehmern bestimmt. Die Ergebnisse zeigen, dass sich bei der subjektiven Bewertung der Frequenzen die wahrgenommene Intensität und Annehmlichkeit antiproportional zueinander verhalten. Die bevorzugte Amplitude ist abhängig von Alter und Geschlecht der Versuchspersonen.

In the E2V project we participated in the development of an innovative electric two-wheel vehicle for closed, non-urban spaces like parklands. In order to enable usage by handicapped and persons without a driving license, the vehicle was designed to be steered with a sidestick which was placed centrally between the two passenger seats. The active sidestick allowed for haptic feedback, e.g. warning the driver when the road is left. Using an OpenDS-based driving simulator, we experimentally compared four different sidestick configurations to identify a secure, efficient and comfortable steering concept. A longitudinally isometric configuration turned out as most popular, but the actual differences were insignificant.

In einer empirischen Untersuchung mit 26 Probanden wurde die Touch-Interaktion ohne und mit haptischer Rückmeldung auf einem neuen Touch-Display der Firma Continental bei Blindbedienung miteinander verglichen. Die Versuchspersonen bearbeiteten dazu verschiedene Sekundäraufgaben im Fahrsimulator. Insgesamt konnte für alle Funktionselemente ein signifikant positiver Einfluss der haptischen Unterstützung auf die Effektivität, subjektive Beanspruchung und Zufriedenheit bei der Bewältigung der Fahraufgabe mit der Sekundärtätigkeit festgestellt werden. Die Ergebnisse zur Fahrerablenkung und Effizienz zeigten keinen signifikanten Unterschied.

Der "elektronische Brief" bzw. die elektronische Mail (E-Mail) ist seit über 30 Jahren im privaten wie beruflichen Umfeld im Einsatz. Behörden, Steuerbüros, Krankenhäuser, Finanzinstitute und viele weitere Gruppen versenden und empfangen E-Mails, um Informationen auszutauschen. Innerhalb kurzer Zeit findet eine E-Mail ihren Weg vom Sender in Deutschland zum Empfänger in beispielsweise den USA. Wie funktioniert das? Und was hat es mit E-Mail-Verschlüsselung auf sich? Dieser Artikel betrachtet die grundlegende technische Funktionsweise der E-Mail sowie Hintergründe und Funktionsweise der Verschlüsselung mit S/MIME und PGP.

Place learning is a process of analyzing various sensor data (e.g., continuously collected Wi-Fi scans) to discover the places, which are related to a user's routines or activities in his daily life. While the geometry-based approaches can correctly distinguish places in different buildings, most of the fingerprint-based approaches can correctly distinguish places in different rooms. However, if two neighbouring places are very near to each other, they are likely to be learned as a single place. Previous studies do not specifically indicate the minimum distance to distinguish neighbouring places. In this paper, we deal with the question of "how near is near" for two neighbouring places, and experimentally investigate the minimum distance required to distinguish two neighbouring places. Results of the case studies show that places in adjacent rooms or with a distance of at least 4-5 meters can be correctly distinguished, while locations with a distance of fewer than 4 meters are likely to be learned as one place in the indoor environments.

Context-aware applications process context information to support users in their daily tasks and routines. These applications can adapt their functionalities by aggregating context information through machine-learning and data processing algorithms, supporting users with recommendations or services based on their current needs. In the last years, smartphones have been used in the field of context-awareness due to their embedded sensors and various communication interfaces such as Bluetooth, WiFi, NFC or cellular. However, building context-aware applications for smartphones can be a challenging and time-consuming task. In this paper, we describe an ontology-based reasoning framework to create context-aware applications. The framework is based on an ontology as well as micro-services to aggregate, process and represent context information.

Subgroup discovery is a broadly applicable descriptive data mining technique for identifying interesting subgroups according to some property of interest. This article summarizes fundamentals of subgroup discovery, before it reviews algorithms and further advanced methodological issues. In addition, we briefly discuss tools and applications of subgroup discovery approaches. In that context, we also discuss experiences and lessons learned and outline future directions in order to show the advantages and benefits of subgroup discovery.

The success of software applications that collect and process personal data does not only depend on technical aspects, but is also linked to social compatibility and user acceptance. It requires experts from different disciplines to ensure legal compliance, to foster the users' trust, to enhance the usability of the application and to finally realize the application. Multidisciplinary requirements have to be formulated, interwoven and implemented. We advocate the use of interdisciplinary design patterns that capture the design know-how of typical, recurring features in socially aware applications with particular concern for socio-technical requirements. The proposed patterns address interdisciplinary concerns in a tightly interwoven manner and are intended to facilitate the development of accepted and acceptable applications that in particular deal with sensitive user context information.
A Novel Method for Securing Critical Infrastructures by Detecting Hidden Flows of Data. Benedetto, Francesco; Giunta, Gaetano; Liguori, Angelo; Wacker, Arno. In Communications and Network Security (CNS), 2015 IEEE Conference on, pp. 648–654. IEEE, 2015.
- [ Abstract ]
- [ BibSonomy-Post ]
This work introduces a novel method for securing critical infrastructures. We propose an innovative hypothesis test for intrusion detection in data communications. In particular, we detect the presence or absence of a covert (i.e. hidden) timing channel. We devised a new testing procedure, namely the Weibullness test, that statistically measures how much the series under investigation (inter-arrival times of the received packets) fits Weibull vs. non-Weibull models. This is equivalent to differentiating between the cases of legitimate and covert data communications. The achieved results show the robustness of this innovative test versus the conventional shape and regularity tests, even in presence of short-lived covert communications for intrusion detection in data communications.

- [ BibSonomy-Post ]
Service evolution is a critical ingredient of the service life-cycle. The more our society depends on large-scale, complex service environments including cloud and mobile services, the more pressing becomes the question of how to evolve a service on-the-fly at runtime without bringing whole systems to a halt. Service inter–dependencies make it increasingly difficult to manage the service collection as a whole. Thus, there is an urgent need for coordinated service evolution. The main contributions of this paper are a conceptual solution for dynamic on-the-fly co-evolution of services, and a framework that supports the engineering of such co-evolution support. We analyze the types of changes that might happen in a service and their potential impact on dependent clients and servers. We present the design of a co-evolution support infrastructure based on a service computing model and platform. Our solution is built on top of the Domain Object concept, and our application domain is smart urban mobility.

In diesem Dokument werden die Ergebnisse und Erkenntnisse aus dem Forschungsprojekt "AAL-Weiterbildung im Tandem (TAAndem)" vorgestellt. Im Rahmen des Forschungsprojekts wurde eine gemeinsame berufliche Weiterbildungsmaßnahme in Form von Blended Learning für Personen sowohl aus pflegerischen bzw. sozialen Berufen als auch aus handwerklichen bzw. technischen Berufen konzipiert und erprobt. Es konnte gezeigt werden, dass der aus dem Sprachenlernen bekannte Tandemlernansatz im Kontext von Ambient Assisted Living (AAL) auf unterschiedliche Berufsgruppen übertragen werden kann. Es hat sich gezeigt, dass ein gemeinsames Lernen und die gegenseitige Vernetzung beider Berufsgruppen für die Erschließung des Themas AAL und die Entwicklung von Beratungskompetenz in diesem Themenfeld sehr hilfreich und nützlich sind. Zur Förderung des gemeinsamen Lernens sind verschiedene Konzepte und Materialien entwickelt worden. Dies geschah sowohl für eine Präsenzphase (Vorträge und Übungen für das Lernen im Tandem), als auch für eine Selbstlernphase (E-Learning). So ist für die Selbstlernphase u. a. ein browserbasiertes Lernspiel mit praxisnahen Fallbeispielen und entsprechenden Inhalten entwickelt worden. Zunächst wurden mit möglichen Teilnehmern der TAAndem-Weiterbildung eine Anforderungserhebung durchgeführt und entsprechende Weiterbildungsinhalte entwickelt. Um die einzelnen Konzeptteile der Weiterbildung zu erproben, wurden diese anschließend mit Personen aus der Zielgruppe getestet (u. a. in Form eines AAL-Schnuppertages) und dann anhand der Ergebnisse weiterentwickelt. Zur Evaluation der gesamten Weiterbildung wurde Anfang 2014 ein Pilotdurchlauf mit 18 Teilnehmer(inne)n aus sozialen und technischen Berufen durchgeführt und wissenschaftlich analysiert, u. a. auf Basis verschiedener Teilnehmerbefragungen. Insgesamt konnte der Erfolg des TAAndem-Weiterbildungsansatzes durch die Evaluationsergebnisse nachgewiesen werden. Hinsichtlich einzelner Teilaspekte, z. B. bezogen auf das E-Learning, bestand allerdings noch Überarbeitungsbedarf im Hinblick auf nachfolgende Weiterbildungstermine. Durch das Projekt war es möglich, wichtige grundlegende Hinweise auf die Ausgestaltung von beruflichen Qualifikationsmaßnahmen im Themenfeld AAL zu erlangen, um einen Beitrag zu leisten, langfristig die Akzeptanz von AAL bei den Endnutzern und Berufspraktikern zu steigern. Die Projektergebnisse können für weiterführende Forschungsarbeiten in diesem Themenfeld genutzt werden.

Im Frühjahr 2014 fand der erste Pilotdurchlauf der TAAndem-Weiterbildung statt, die derzeit im Rahmen des gleichnamigen und vom BMBF geförderten Projektes "TAAndem - AAL-Weiterbildung im Tandem" entwickelt wird. Ziel des Projektes ist, Personen aus unterschiedlichen Berufsbereichen (hier Personen aus technischen und Personen aus sozialen Berufen), die zukünftig beruflich mit Ambient Assisted Living (AAL) arbeiten werden, durch die Weiterbildung zusammenzubringen, so dass diese beiden Berufsgruppen von und miteinander zum Thema lernen können. Im Projekt wird das sog. Tandemlernen, welches aus dem Fremdsprachenlernen bekannt ist, adaptiert, da davon auszugehen ist, dass beide Berufsgruppen von ihrem bisher (im Beruf) erworbenen Wissen profitieren können. Für die Realisierung der Weiterbildung wird ein Blended-Learning-Ansatz verfolgt, bei dem Präsenzlehre durch ein E-Learning-Angebot zum Selbstlernen ergänzt wird. Die Ergebnisse des ersten Durchlaufs werden in diesem Artikel vorgestellt.

Unfortunately, every year many vulnerable road users (VRUs), such as pedestrians or bicyclists are killed or seriously injured in traffic accidents. Several research groups are working on different solutions including radar or laser based approaches to reduce the number of traffic accidents VRUs are involved. The approach presented in this paper is based on wireless communications such as WLAN and 5G/LTE and a "context filter". The "context filter" identifies vulnerable road users in potentially dangerous situations based on several contexts (VRU position, movement direction, accelerations). An identified dangerous situation is communicated between the VRU and the cars using wireless communication such as ad hoc or cellular systems. As one specifically interesting context for identifying dangerous situations this paper investigates on detecting pedestrians stepping onto the road. We examine smartphone sensor data and several reasoning classifiers to investigate whether "stepping onto the road" by detecting a pedestrian "crossing a curb" is possible. To the best of our knowledge detecting pedestrians crossing a curb by using smartphone sensors, has not been investigated so far.

A person's context data can be used for a multitude of applications, such as energy management or health care. Common context recognition approaches rely on several factors, such as the sensor set, features, or the context modeling algorithm. Discovering the recognition performances of different parameter setting combinations is a complex, time-consuming, and error-prone task. To support the context recognition research, we present the Context Recognition Assistance Tool (CRAT). The Context Recognition Assistance Tool assist by automatically conducting the evaluation for a multitude combination of parameter settings and clearly presents the findings. Using the CRAT, we investigate to what degree five parameters influence the recognition accuracy. To support the research in the field of context recognition, the CRAT is publicly available.

Ubiquitous Computing is an emerging research area of computer science. Similarly, social network analysis and mining became very important in the last years. We aim to combine these two research areas to explore the nature of processes happening around users. The presented research focuses on exploring and analyzing different groups of persons or entities (communities, clusters and classes), their stability and semantics. An example of ubiquitous social data are social networks captured during scientific conferences using face-to-face RFID proximity tags. Another example of ubiquitous data is crowd-generated environmental sensor data. In this paper we generalize various problems connected to these and further datasets and consider them as a task for measuring group stability. Group stability can be used to improve state-of-the-art methods to analyze data. We also aim to improve the performance of different data mining algorithms, eg. by better handling of data with a skewed density distribution. We describe significant results some experiments that show how the presented approach can be applied and discuss the planned experiments.
Supporting Peat Fire Management using Social Media. Kibanov, Mark; Amin, Imaduddin; Lee, Jong Gun. 2015.
- [ Abstract ]
- [ BibSonomy-Post ]
Peat fires and haze originating from such fires cause a large spectrum of ecological, social and economical problems as well as health issues. Indonesia is a country where peat fires are prevalent and the population suffers from the ensuing haze problems. Two Indonesian islands (Sumatra and Kalimantan) are most affected by peat fires. In this abstract, considering the fact that the usage of social media in Indonesia is high (with 72 million accounts in social networks), it is expected that insights generated from social media can help central and local authorities to improve peat fire management. In particular, we focus on peat fires in the year 2014 in Riau Province, which is one of the most haze-affected areas on Sumatra Island.

After publishing data on the Internet, the data publisher loses control over it. However, there are several situations where it is desirable to remove published information. To support this, the European Union proposed the General Data Protection Regulation (GDPR) which states that providers must remove the data when the corresponding owner requests it. However, the data might already have been copied by third parties. Therefore, Article 17 of the GDPR includes the regulation that the provider must also inform all third parties about the users request. Hence, the providers would need to track every access, which is hard to achieve. This technical infeasibility is a gap between the legislation and the current technical possibilities. To close this gap, we propose a novel service which gives the data owner the possibility to inform simultaneously all providers about her removal request.

Spätestens seit der Veröffentlichung des Entwurfs für die EU-weite Datenschutzregelung ist ausgiebig diskutiert worden, dass die im Artikel 17 beschriebenen Regelungen für das Löschen, insbesondere die Pflicht, Dritte über die gewünschte Löschung zu informieren, aufgrund der fehlenden technischen Lösung in der Praxis nicht umsetzbar sind. Seit Mai 2014 hat die öffentliche Diskussion eine neue Wendung genommen, als Google gerichtlich verurteilt wurde, auf Antrag bestimmte Links zu löschen. Verallgemeinert kann gesagt werden, dass es an Kritik an dem Artikel 17 wegen der Schwierigkeit, ihn in der Praxis zu realisieren, nicht mangelt. Es mangelt jedoch an konkreten Lösungsvorschlägen für die technische Umsetzung, sodass Dienstanbieter ein Werkzeug zur Verfügung hätten, das Gesetz umzusetzen. In diesem Aufsatz wird ein solches System vorgestellt, welches sowohl den Internet-Nutzern als auch den Dienstanbietern ein Werkzeug zur Unterstützung des Gesetzes zur Verfügung stellt.

Smartphone sensors deliver useful information for applications such as indoor and outdoor navigation. An integral part of such applications is the detection of the orientation and movement direction of a smartphone user. Until now, movement direction detection using smartphones typically relies on GPS, which is often not available indoors. Alternatively, other approaches use sensors such as accelerometer and compass instead. These approaches rely on carrying the smartphone in a predefined orientation, or knowing the orientation of the smartphone in relation to the orientation of the user. In this paper, we present an approach to detecting the orientation and movement direction of users carrying smartphones inside the trouser pocket. This approach first determines the orientation of the smartphone's top using compass and orientation sensor. Second, this approach determines the orientation of the smartphone's screen, and the user's movement direction by observing compass and accelerometer during at least two steps the user takes. After these two steps, the approach is capable of continuously aligning smartphone orientation and user orientation. With our approach, the user is free to change direction, movement speed, or to stop moving at all. The smartphone can be placed in the trouser pocket arbitrarily. And the smartphone is free to wobble in the trouser pocket. How well our approach works, is investigated based on experimental measurements.

The Hagelin M-209 portable encryption device was used by the US Army in World War II and the Korean War, as well as by other armies and in embassy settings. In this paper, we present a fully automated computerized known-plaintext attack, based on hillclimbing and a novel fitness function - the Aggregate Displacement Error. In our performance evaluation we show that we are able to recover key settings for messages as short as 50 characters. To validate our results, we solved several publicly available challenge messages, including a message with only 40 letters.

- [ BibSonomy-Post ]
Many contexts dealing with sensitive information require high-robustness and high-assurance certified security systems that should not be affected by known vulnerabilities. Covert channels are illicit paths that could be exploited by attackers to convey illicit data flows that contravene the security policies. Many implementations of the so-called Covert Storage Channels exist, whereas no implementation of Covert Timing Channels is available. In this paper, we first discuss an Open-Source Covert Timing Channel implementation, describing in detail our innovative approach. Then, we analyze real TCP traffic in the presence of our covert channel for three scenarios of interest, varying the number of hops and round trip time of the connections. The results, from real network traffic monitoring, confirm the validity of our open-source covert timing channel implementation for hidden TCP traffic analysis, in different environmental and operating network conditions.

This paper presents FRASAD, an effective model-driven software development framework to manage the complexity of Internet of Things (IoT) applications. We propose a node-centric software architecture and a rule-based programming model that allow designers to describe their application using only sensor node domain concepts. The final application code is successively generated from the initial models through an automatic model transformation process. The evaluation results show that our framework enables a fast way to develop IoT applications by reducing the cost of dealing with the heterogeneity and complexity exhibited by sensor nodes and their operating systems.

Um Nutzungsbarrieren bei der Smartphone-basierten multi-modalen Mobilitätsassistenz in Bezug auf Nutzer unterschiedlicher Technikgenerationen zu identifizieren, wurden die Aspekte Gebrauchs-tauglichkeit und Akzeptanz im Rahmen einer Laborstudie mit zwei Alters-kohorten evaluiert. Die Ergebnisse der Studie zeigen, dass die unter-suchte Applikation „Moovel“ von beiden Alterskohorten eine hohe Akzeptanz und subjektiv empfundene Gebrauchstauglichkeit erfährt. Objektiv konnten jedoch, in Bezug auf Effektivität und Effizienz, auch signifikante Unterschiede zwischen den Versuchsgruppen festgestellt werden, welche Nutzungsbarrieren und somit Gestaltungspotentiale für die Weiterentwicklung multimodaler Mobilitätsapplikationen aufzeigen.

This paper presents the results of the project IMPERA (Integrated Mission Planning for Distributed Robot Systems). The goal of IMPERA was to realize an extraterrestrial exploration scenario using a heterogeneous multi-robot system. The main challenge was the development of a multi-robot planning and plan execution architecture. The robot team consists of three heterogeneous robots, which have to explore an unknown environment and collect lunar drill samples. The team activities are described using the language ALICA (A Language for Interactive Agents). Furthermore, we use the mission planning system pRoPhEt MAS (Reactive Planning Engine for Multi-Agent Systems) to provide an intuitive interface to generate team activities. Therefore, we define the basic skills of our team with ALICA and define the desired goal states by using a logic description. Based on the skills, pRoPhEt MAS creates a valid ALICA plan, which will be executed by the team. The paper describes the basic components for communication, coordinated exploration, perception and object transportation. Finally, we evaluate the planning engine pRoPhEt MAS in the IMPERA scenario. In addition, we present further evaluation of pRoPhEt MAS in more dynamic environments.

The issue of sustainability is at the top of the political and societal agenda, being considered of extreme importance and urgency. Human individual action impacts the environment both locally (e.g., local air/water quality, noise disturbance) and globally (e.g., climate change, resource use). Urban environments represent a crucial example, with an increasing realization that the most effective way of producing a change is involving the citizens themselves in monitoring campaigns (a citizen science bottom-up approach). This is possible by developing novel technologies and IT infrastructures enabling large citizen participation. Here, in the wider framework of one of the first such projects, we show results from an international competition where citizens were involved in mobile air pollution monitoring using low cost sensing devices, combined with a web-based game to monitor perceived levels of pollution. Measures of shift in perceptions over the course of the campaign are provided, together with insights into participatory patterns emerging from this study. Interesting effects related to inertia and to direct involvement in measurement activities rather than indirect information exposure are also highlighted, indicating that direct involvement can enhance learning and environmental awareness. In the future, this could result in better adoption of policies towards decreasing pollution.

Der Beitrag befasst sich mit Konzepten des Freizeitverkehrs in der Region Nordhessen. Infolge der hohen Orientierung nordhessischer Besucher am MIV für An- und Abreise sowie Mobilität vor Ort sind Besucherverkehre bisher wenig umweltverträglich. Integrierte Angebote, die Mobilität, Tourismus sowie den gesamten Prozess des Verkehrsverhaltens berücksichtigen, können wesentlicher Bestandteil einer klimaneutralen nicht-alltäglichen Freizeitmobilität sein. Der Beitrag zeigt die Chancen im Freizeitverkehr auf.

Hintergrund / Zielsetzung: Berührungsempfindliche Bildschirme (Touchscreens) werden nicht mehr ausschließlich in mobilen Endgeräten wie Smartphones eingesetzt, sondern zunehmend auch in Geräten des Arbeitsalltags wie z. B. an Kassenterminals oder in Industrieanlagen. Allerdings fehlt die über den Tastsinn vermittelte haptische Rückmeldung und das gewohnte Gefühl von mechanischen Tasten geht verloren. Die Bedienung an einer glatten Oberfläche ist schwieriger, was sich u.~a. in geringeren Eingabegeschwindigkeiten sowie einer höheren Fehlerrate äußert. Im Projekt InterHapt werden Möglichkeiten untersucht, eine künstlich generierte haptische Rückmeldung bei Touchscreens so zu gestalten, dass sie an die menschliche Wahrnehmungsfähigkeit angepasst ist und gleichzeitig hilft, die o.~g. Einschränkungen zu kompensieren. Ziel dieses Beitrags ist es, die minimale Amplitude, die auf einer ebenen Fläche noch als wahrnehmbarer Stimulus erkannt wird, in Abhängigkeit verschiedener Frequenzen experimentell zu bestimmen. Diese Werte liefern Erkenntnisse zur optimalen Gestaltung einer haptischen Rückmeldung. Methode: Zehn Probanden (7 m, 3 w) im Alter von 25,5~±~2,6~Jahren nahmen an der Studie teil. Mit Hilfe eines Körperschallwandlers wurden in randomisierter Reihenfolge sechs unterschiedliche Frequenzen auf eine ebene Plexiglasplatte appliziert, auf der sowohl der linke als auch der rechte Zeigefinger des Probanden nacheinander positioniert wurde. Die minimal wahrnehmbare Amplitude jeder Frequenz wurde mittels Herstellungsmethode durch jeweils eine Aufwärts- und eine Abwärtsmessung ermittelt. Insgesamt wurden demnach 240 Einzelmessungen in die Auswertung einbezogen. Ergebnisse: Das Ergebnis dieser Studie zeigt, dass unter diesen Bedingungen die Absolutschwelle bei 100~Hz am niedrigsten und somit die Wahrnehmung am intensivsten war. Stimuli wurden bereits ab einer Amplitude von 1,77~μm wahrgenommen, wohingegen bei den anderen Frequenzen höhere Amplituden (50~Hz: 4,27~μm; 250~Hz: 3,93~μm; 500~Hz: 5,11~μm; 750~Hz: 5,35~μm; 1000~Hz: 7,68~μm) nötig waren, um eine fühlbare Wahrnehmung zu erzeugen. Diskussion / Schlussfolgerungen: Mögliche Einflüsse von Geschlecht, Alter und Breite des Zeigefingers werden bis zum Symposium geprüft. In weiteren Untersuchungen muss nun ermittelt werden, ob diese unter Laborbedingungen ermittelten Ergebnisse in anwendungsbezogenen Kontexten bestätigt werden können.

Touchscreens werden zunehmend in alltäglichen Geräten eingesetzt, wobei das Gefühl konventioneller Tasten verloren geht. Für die Entwicklung von Gestaltungsempfehlungen einer haptischen Rückmeldung von Touchscreens wurde mittels Online-Umfrage eine Analyse des Nutzungsverhaltens bezüglich mobiler Endgeräte von 325 Teilnehmern durchgeführt. Die Ergebnisse zeigen, dass haptische Rückmeldung zwar bekannt ist, aber nicht als wichtig empfunden und daher meist deaktiviert wird. Bei der Interaktion mit mobilen Endgeräten werden vornehmlich die Daumen und Zeigefinger genutzt, wobei jüngere Nutzer überwiegend beide Daumen und ältere Nutzer den Zeigefinger zur Interaktion einsetzen.

Das neuartige Elektrofahrzeug „E2V“ soll von älteren und in ihrer Mobilität eingeschränkten Menschen ohne Führerschein verwendet werden können. Über ein integriertes Informationssystem sollen Nutzer ohne Computerkenntnisse u. a. touristische Informationen abrufen und Fahrrouten planen können. Dieser Beitrag beschreibt die systematische Auswahl, Kombination und Verwendung geeigneter Methoden zur nutzerorientierten Evaluation dieses Informationssystems. So wurden verschiedene leichtgewichtige Evaluationsmethoden eingesetzt und Nutzertests in einem Fahrsimulator durchgeführt, um Probleme bzgl. der Benutzbarkeit zu identifizieren. Die Ergebnisse reflektieren insbesondere spezielle Bedürfnisse der Nutzergruppe älterer Personen ohne Computererfahrung.

Im Projekt E2V wurde ein neuartiges, zweirädriges Elektrofahrzeug für abgeschlossene, nicht urbane Räume wie den Kasseler Bergpark Wilhelmshöhe entwickelt. Die Steuerung des Fahrzeuges erfolgt über einen zentral zwischen beiden Sitzplätzen angebrachten Side Stick, sodass auch Personen ohne Führerschein oder mit körperlichen Einschränkungen das Fahrzeug nutzen können. Der verwendete aktive Side Stick ermöglicht, den Fahrer durch haptische Signale z. B. auf das Abkommen vom Weg hinzuweisen und das Übertragungsverhalten per Software zu konfigurieren. Um ein sicheres, effizientes und komfortables Steuerungskonzept für das E2V zu bestimmen, wurden verschiedene Konfigurationen des aktiven Side Sticks definiert und in einem OpenDS-basierten Fahrsimulator getestet. Signifikante objektive Unterschiede wurden nicht festgestellt, aber eine subjektive Präferenz für ein auf der Längsachse isometrisches und auf der Querachse isotonisches Steuerungskonzept.

Sensors embedded in smartphones are an essential component for activity recognition. Even though the accelerometer is the most widely used sensor, the highest recognition accuracies are obtained when using data collected from multiple sensors. However, the use of multiple sensors has an adverse impact on the energy consumption of power-limited devices such as smartphones. In this paper, we present a new method to improve the recognition accuracy of physical activities by using only the accelerometer. We utilize a low-pass filter to split the acceleration data into a low- and a high-frequency component. These components provide a new set of features, which can be used as a complement to the raw acceleration to reduce the number of sensors needed to recognize physical activities. After evaluating our method for a public dataset, we found that our approach represents an average of up to 16% increase in the recognition accuracy over the raw acceleration data, outperforming even widely used combinations such as the raw acceleration plus the gyroscope. The highest accuracies are obtained when using a cut-off frequency in the interval [0:001 - 0:05] Hz as well as a combination of the acceleration with its low-frequency component.

Wi-Fi fingerprinting without site surveys is one interesting approach for indoor localization. Current approaches in this field either achieve high accuracy with a large fingerprint database, or yield lower accuracy when the database size is small. In this paper, we propose a novel RSS (Received Signal Strength)-range based approach for fingerprint building, which optimizes the size of the fingerprint database while maintaining the accuracy at the same level. In this approach, a fingerprint is a low-dimensional vector of RSS-ranges, which are extracted from a high-dimensional vector of Wi-Fi scans in the process of fingerprint building. The proposed approach is used and evaluated in the autonomous localization system, which we call WHERE. The evaluation results show the system can optimize the size of the fingerprint database while maintaining an accuracy of room-level.

Scholarly success is traditionally measured in terms of citations to publications. With the advent of publication man- agement and digital libraries on the web, scholarly usage data has become a target of investigation and new impact metrics computed on such usage data have been proposed – so called altmetrics. In scholarly social bookmarking sys- tems, scientists collect and manage publication meta data and thus reveal their interest in these publications. In this work, we investigate connections between usage metrics and citations, and find posts, exports, and page views of publications to be correlated to citations.

The application of ubiquitous and social computational systems shows a rapidly increasing trend in our everyday environments: Enhancing social interactions and communication in both online and real-world settings is an important issue in a broad range of application contexts. This chapter describes the development of ubiquitous and social software for enhancing social networking. The Connect-U demonstrator features a class of such applications. In particular, it comprises the Conferator and MyGroup applications for enabling smarter social interactions in the context of conferences and working groups. We describe the applied socio-technical design process, and discuss experiences and lessons learned.

To draw on the full potential of Ubiquitous Computing (UC) systems, they have to be designed with awareness for their social embedding in order to increase the user acceptance. To this end, not only the compliance with laws has to be ensured, but also usability-enhancing and trust and confidence-building measures have to be applied. This makes the development of UC applications a challenging task that involves experts from different disciplines. The main contribution of this report is a set of design patterns for UC applications that specifically focus on the interweaving and implementation of multidisciplinary requirements. The patterns capture the design know-how of typical, recurring features in context-aware adaptive UC applications with particular concern for the sociotechnical requirements. First, we present a detailed discussion of the related work on design patterns in the realm of UC. Afterwards, we explain our research methodology and the template structure of our pattern specifications. The core of the report consists of eight interdisciplinary UC design patterns. This initial list of patterns was derived from several application case studies in the interdisciplinary research project LOEWE-VENUS. We view this collection as a starting point for an evolving set of commonly accepted reusable design patterns that facilitate the development of accepted and acceptable UC applications.

Ubiquitous applications are complex systems, and need to be evaluated with respect to their social compatibility in an encompassing and interdisciplinary approach. Interdisciplinary work bears the challenge of maintaining the strengths and specialities of each discipline while yielding consistent results at the same time. Also, the evaluation should be well-matched with other activities in the process of development. The presented system evaluation is designed to fulfill these goals as part of the VENUS Development Method . The system evaluation brings a development circle to a conclusion, and generates consistent results that facilitate decisions for next steps. The evaluation also yields suggestions for possible, further improvements. System evaluation unites four disciplines: usability engineering , trust engineering , legal compatible technology design , and security analysis . This chapter describes the starting points of each discipline, and derives an interdisciplinary approach which encompasses a concerted operating plan as well as contentual interdisciplinary cooperation. The system evaluation provides joint solutions for empirical work, but also leaves room for disciplinary analyses.

Social tagging systems have established themselves as an important part in today's web and have attracted the interest from our research community in a variety of investigations. The overall vision of our community is that simply through interactions with the system, i.e., through tagging and sharing of resources, users would contribute to building useful semantic structures as well as resource indexes using uncontrolled vocabulary not only due to the easy-to-use mechanics. Henceforth, a variety of assumptions about social tagging systems have emerged, yet testing them has been difficult due to the absence of suitable data. In this work we thoroughly investigate three available assumptions - e.g., is a tagging system really social? - by examining live log data gathered from the real-world public social tagging system BibSonomy. Our empirical results indicate that while some of these assumptions hold to a certain extent, other assumptions need to be reflected and viewed in a very critical light. Our observations have implications for the design of future search and other algorithms to better reflect the actual user behavior.

Social tagging systems have established themselves as an important part in today's web and have attracted the interest of our research community in a variety of investigations. This has led to several assumptions about tagging, such as that tagging systems exhibit a social component. In this work we overcome the previous absence of data for testing such an assumption. We thoroughly study social interaction, leveraging for the first time live log data gathered from the real-world public social tagging system bibs. Our results indicate that sharing of resources constitutes an important and indeed social aspect of tagging.

Der Beitrag beschreibt das Forschungsprojekt Robotair, dessen Ziel die Entwicklung und Evaluation eines prototypischen, kostengünstigen Boden-Luft-Servicerobotersystems ist. Das System wird für die Detektion und Ortung von Druckluftleckagen zwecks nachhaltiger Ressourcen- und Energienutzung sowie für die Erfassung von Arbeitsumgebungsfaktoren zur Sicherstellung gesunder Arbeitsbedingungen verwendet. Es besteht aus einem teleoperiert fliegenden und einem teilautonom fahrenden Roboter, die beide mit sensorischer Nutzlast ausgestattet sind, sowie einem mobilen Leitstand. Dort wird aus den Sensorsignalen ein aussagekräftiges Lagebild erstellt und dem Nutzer visualisiert. Insbesondere wird die Mensch-Roboter-Interaktion zur Planung, Überwachung und Dokumentation der Inspektionsaufgaben sowie die Teleoperation des Flugroboters durch einen menschlichen Operator vorgestellt. Die Teleoperation soll menschliche Fähigkeiten synergetisch in das System integrieren und wird eingesetzt, falls der Mensch in der Lage ist, bei der Bearbeitung einer Aufgabe bessere Ergebnisse zu erzielen. Zur Unterstützung der Teleoperation wird u. a. eine Datenbrille eingesetzt, die relevante Daten in einer Augmented-Reality-Umgebung visualisiert

The aim of the TAAndem-project is to develop a common further education for people from different kinds of professions within the context of "Ambient Assisted Living" (AAL). The further education is addressed to geriatric nurses and craftsmen. The didactic method of tandem learning is applied, so people from various working fields can learn with and from each other. In this paper we will present our concept and the steps of development following the user centred design. Different aspects of the further education that are essential for the upcoming pilot run were tested among potential participants. Methods used were requirement analysis, questionnaire surveys, qualitative expert evaluations and empirical observations. The main result is that the didactic method of tandem learning is suitable for transmitting knowledge to our target group. Several results are given in the following article.

Temporal dynamics of social interaction networks as well as the analysis of communities are key aspects to gain a better understanding of the involved processes, important influence factors, their effects, and their structural implications. In this article, we analyze temporal dynamics of contacts and the evolution of communities in networks of face-to-face proximity. As our application context, we consider four scientific conferences. On a structural level, we focus on static and dynamic properties of the contact graphs. Also, we analyze the resulting community structure using state-of-the-art automatic community detection algorithms. Specifically, we analyze the evolution of contacts and communities over time to consider the stability of the respective communities. Furthermore, we assess different factors which have an influence on the quality of com- munity prediction. Overall, we provide first important insights into the evolution of contacts and communities in face-to-face contact networks.

In this paper, we present two new algorithms for distributed volunteer computing. Both algorithms have in common, that they are self-organized. Due to the self-* properties of our algorithms, the reliability of the distributed computing is increased. The network, which builds the basis for the distribution, is an unstructured peer-to-peer (p2p) network. Since there is no central managing unit and no structured addressable overlay in such networks, each peer has to self-organize the job selecting process, the distribution of jobs, and the merging of finished jobs obtained from neighbors. After presenting our two algorithms, namely the Epoch-Distribution-Algorithm and the Sliding-Window-Distribution-Algorithm, we present open questions. Since these algorithms are strongly based on self-organization and peers are working absolute autonomously and other some self-* properties, the algorithms can be classified into to world of the organic computing.

Hintergrund / Zielsetzung: In vielen industrialisierten Ländern verändert sich die Bevölkerungsstruktur: Die geburtenstarken Jahrgänge der Nachkriegszeit werden in einigen Jahren aus dem Erwerbsleben ausscheiden. Die nachfolgende Generation, zahlenmäßig unterlegen, wird auf Grund der wirtschaftlichen Entwicklungen und den Herausforderungen zur Finanzierung der Renten mindestens bis in ihr 67stes Lebensjahr berufstätig sein. Um diesen Veränderungen Rechnung zu tragen, sind Arbeitsplätze so zu gestalten, dass sie auch für Menschen in fortgeschrittenem Alter geeignete Arbeitsbedingungen bieten. Eine Möglichkeit die ergonomischen Anforderungen Älterer zu überprüfen, ist die Verwendung von Alterssimulationsanzügen, die u. a. Mobilitätseinschränkungen bei noch nicht eingeschränkten Personen simulieren. Ziel dieses Beitrages ist es, einen ersten Ansatz für eine wissenschaftliche Belegung eines Alterssimulationsanzuges mit flexiblen Gurten zu liefern. Wichtig ist dabei die Frage, in wie fern und in welchem Maße er Einschränkungen simuliert. Hintergrund ist die Fragestellung, ob sich Alterssimulationsanzüge als Werkzeug z. B. für die Gestaltung von Arbeitsplätzen eignen. Methode: In einem ersten Versuch wurden die Einschränkungen beim Gehen in Schrittgeschwindigkeit untersucht. Hierzu wurde eine 3,5 m lange Strecke mit und ohne Anzug von jeweils zwei Probanden abgegangen und die Bewegungen mit Hilfe eines Motion-Tracking-Systems (ARTtrack 2) aufgezeichnet und verglichen. Ausgewertet wurden Parameter aus der Ganganalyse. Diese umfassten den Gangzyklus und die Winkelverläufe von Hüfte, Knie und Sprunggelenk. Ergebnisse: Erste Ergebnisse zeigen, dass der Anzug zu einem alterstypischen, pathologischen Gangbild führt. Typisch ist z. B. die Minimierung der Schrittlänge. Der Knieflexionswinkel weist mit Anzug eine höhere Amplitude auf, da der Anzug ein Durchstrecken der Knie verhindert. Unterschiede in der Gurtlänge von linker zu rechter Seite wirken sich auf die Winkel aus. Diskussion / Schlussfolgerungen: Ob auch andere Mobilitätseinschränkungen und eine graduelle Einstellung von "etwas eingeschränkt" bis "sehr eingeschränkt" möglich ist, muss in weiteren Versuchen ermittelt werden.

Applications of the Social Web are ubiquitous and have become an integral part of everyday life: Users make friends, for example, with the help of online social networks, share thoughts via Twitter, or collaboratively write articles in Wikipedia. All such interactions leave digital traces; thus, users participate in the creation of heterogeneous, distributed, collaborative data collections. In linguistics, the

The 15th ECML PKDD Discovery Challenge centered around the recommendation of given names. Participants of the challenge implemented algorithms that were tested both offline - on data collected by the name search engine Nameling - and online within Nameling. Here, we describe both tasks in detail and discuss the publicly available datasets. We motivate and explain the chosen evaluation of the challenge, and we summarize the different approaches applied to the name recommendation tasks. Finally, we present the rankings and winners of the offline and the online phase.

Use of smartphones for work and well-being in the evening: The role of autonomous and controlled motivation. Ohly, Sandra; Latour, Alessa. In Journal of Personnel Psychology, 13(4), pp. 174–183 (DOI:10.1027/1866. 2014.
- [ Abstract ]
- [ BibSonomy-Post ]
Recent research has revealed that use of smartphones for work in the evening is associated with lower well-being. In this study, based on self-determination theory, we examined the role of autonomous and controlled motivation for well-being in the evening. Hierarchical regression analyses using data from 1,714 working individuals revealed that work-related smartphone usage in the evening was positively related to psychological detachment, but unrelated to recovery and negative affect, and negatively related to positive affect. Autonomous motivation for smartphone usage in the evening was positively related to recovery, psychological detachment, and positive affect. Controlled motivation was significantly related to positive and negative affect in the expected direction. These results indicate that the motivation behind individuals’ smartphone use in the evening matters for their well-being.

Der Technologietrend zu tragbaren, stets mit dem Internet verbundenen Geräten, die den Menschen mit vielfältiger Sensorik und Aktorik unterstützen sollen, geht gleichzeitig einher mit innovativen Möglichkeiten der Mensch-Maschine-Interaktion. Um eine gebrauchs¬taugliche Nutzung dieser smarten Technologien zu gewährleisten, sind dafür entsprechende Gestaltungsempfehlungen erforderlich. Dieser Beitrag beschreibt den aktuellen Stand der Lösungsansätze unter Berücksichtigung menschlicher Eigenschaften sowie technischer Potenziale, fasst vorhandene Gestaltungsempfehlungen zusammen und macht den Forschungsbedarf deutlich. Dazu werden Gestaltungsempfehlungen für haptisches Feedback bei Touchscreens, für die Visualisierung mit Datenbrillen und für die 3-D-Gesteninteraktion betrachtet und gleichzeitig ein Einblick in verschiedene Forschungsprojekte des Fachgebiets gegeben.

Gestensteuerungen wird als einer natürliche Interaktionsform das Potential zugeschrieben, herkömmliche Eingabegeräte in vielen Anwendungsbereichen zu ersetzen. Fortschritte in der technischen Realisierung führen dazu, dass auch im Bereich der Mensch-Roboter-Interaktion 3-D-Gestensteuerungen erste experimentelle Verwendung finden. Gleichzeitig werden allerdings Zweifel an der Gebrauchstauglichkeit von Gestensteuerungen geäußert. In einer Laborstudie wurde eine intuitiv empfundene 3-D-Gestensteuerung mit einer herkömmlichen Steuerung für einen mobilen Serviceroboter verglichen. Im Ergebnis wurde deutlich, dass die Gestensteuerung für die Steuerung eines Manipulatorarms des Roboters vielversprechend, aber für Fahraufgaben des mobilen Serviceroboters weniger gut geeignet ist, und es Bedarf nach Gestaltungsempfehlungen für den Entwurf von 3-D-Gesten und deren ergonomische Bewertung gibt.

Purpose – To avoid harm to humans, environment, and capital goods, hazardous or explosive gases that are possibly escaping from industrial and infrastructure facilities of the gas and oil processing industry have to be detected and located quickly and reliably. Project RoboGasInspector aims at the development and evaluation of a human-robot system that applies autonomous robots equipped with remote gas detection devices to detect and locate gas leaks. This article aims to focus on the usability of telemanipulation in this context. Design/methodology/approach – This paper presents four user studies concerning human-robot interfaces for teleoperation in industrial inspection tasks. Their purpose is to resolve contradictory scientific findings regarding aspects of teleoperation and to verify functionality, usability, and technology acceptance of the designed solution in the actual context of use. Therefore, aspects concerning teleoperation that were separately examined before are evaluated in an integrated way. Considered aspects are influence of media technology on telepresence, simulator sickness and head slaved camera control, usability of different input devices for telemanipulation, and identification of intuitive gestures for teleoperation of mobile robots. Findings – In general, the implemented interaction concepts perform better compared to conventional ones used in contemporary, actually applied robot systems. Otherwise, reasons are analyzed and approaches for further improvements are discussed. Exemplary results are given for each study. Originality/value – The solution combines several technical approaches that are so far separately examined. Each approach is transferred to the innovative domain of industrial inspections and its applicability in this context is verified. New findings give design recommendations for remote workplaces of robot operators.

With the rapid development of mobile technologies like, e.g., RFID tags, smartphones, and tablets, ambient intelligence applications have gained a huge popularity in recent years. However, most of the existing approaches aim at developing ambient environments that are rather static, and do not take the aspect of social interaction between the inhabitants into account. We argue that this is essential for smart classrooms, meeting rooms and other environments that are strictly based on mechanisms of human face-to-face interactions. In the context of the smart university, we propose the ambient classroom system for enhancing collaborative educational processes using sensor fusion, data mining, semantic technologies, and inference methods.

The development of ICT infrastructures has facilitated the emergence of new paradigms for looking at society and the environment over the last few years. Participatory environmental sensing, i.e. directly involving citizens in environmental monitoring, is one example, which is hoped to encourage learning and enhance awareness of environmental issues. In this paper, an analysis of the behaviour of individuals involved in noise sensing is presented. Citizens have been involved in noise measuring activities through the WideNoise smartphone application. This application has been designed to record both objective (noise samples) and subjective (opinions, feelings) data. The application has been open to be used freely by anyone and has been widely employed worldwide. In addition, several test cases have been organised in European countries. Based on the information submitted by users, an analysis of emerging awareness and learning is performed. The data show that changes in the way the environment is perceived after repeated usage of the application do appear. Specifically, users learn how to recognise different noise levels they are exposed to. Additionally, the subjective data collected indicate an increased user involvement in time and a categorisation effect between pleasant and less pleasant environments.

Since the rise of collaborative tagging systems on the web, the tag recommendation task -- suggesting suitable tags to users of such systems while they add resources to their collection -- has been tackled. However, the (offline) evaluation of tag recommendation algorithms usually suffers from difficulties like the sparseness of the data or the cold start problem for new resources or users. Previous studies therefore often used so-called post-cores (specific subsets of the original datasets) for their experiments. In this paper, we conduct a large-scale experiment in which we analyze different tag recommendation algorithms on different cores of three real-world datasets. We show, that a recommender's performance depends on the particular core and explore correlations between performances on different cores.

Bei der Gestaltung von grafischen Benutzeroberflächen sind Schriftart und Schriftgrad von Texten, wie z.B. für Schaltflächenbeschriftungen, Hilfetexten oder Tooltipps, geeignet festzulegen. Verfügbare Empfehlungen aus Normen oder Fachliteratur führen zu einer Angabe der Zeichenhöhe in Millimetern statt Punkt und lassen die typografischen Besonderheiten sowie den softwaretechnischen Einfluss gänzlich unberücksichtigt. Der Lösungsansatz für ein einfach anzuwendendes Berechnungsverfahren zur Festlegung des Schriftgrades umfasste die Recherche der relevanten Grundlagen in den Bereichen Ergonomie, Typografie sowie Soft- und Hardware, aus denen Faktoren, die den Schriftgrad beeinflussen, identifiziert werden konnten. Aus diesen Faktoren konnte schrittweise eine Berechnung hergeleitet werden, die sich abschließend vereinfachen ließ. Die Anwendbarkeit und Übertragbarkeit der Berechnung konnte an einem Anwendungsbeispiel aus der Praxis nachgewiesen werden.

In aktuellen Fahrzeugen sind teilweise bereits Touchpads als Nachfolger von Dreh-Drück-Stellern, mechanischen Tasten und Schaltern zu finden. Doch im Gegensatz zu ihren mechanischen Vorgängern fehlt bei der Touchpadinteraktion eine haptische Rückmeldung bei der Auswahl und Betätigung eines auf einem Bildschirm dargestellten Eingabeelements, wie zum Beispiel einer Taste. Um diesen Nachteil zu beheben, wurde von der Firma Continental der Prototyp eines Touchpads entwickelt, der auf Basis einer eindimensional angeregten Masse haptische Rückmeldungen ermöglicht. Im Rahmen einer empirischen Nutzerstudie wurde der Einfluss der elektromechanischen haptischen Rückmeldung bei der Fahrer-Fahrzeug-Interaktion auf Fahrerablenkung, Effektivität, Effizienz des Touchpads und Zufriedenstellung des Fahrers untersucht. Die Evaluation des Prototyps des haptischen Touchpads wurde mit 32 Probanden im Fahrsimulator durchgeführt. Mit Hilfe des Lane Change Tests, Videobeobachtung und automatisierter Emotionsanalyse konnte ein signifikant positiver Einfluss für die Fahrerablenkung und die Effizienz bei der Bewältigung von Nebenaufgaben festgestellt werden. Die Ergebnisse zur Effektivität und Zufriedenstellung zeigten keinen signifikanten Einfluss.

The protection of vulnerable road users, like pedestrians and bicyclists, and the communication between vehicles and their environment, which is called Car2X-Communication, are two scopes in the development of the automotive industry that have gained much interest in the last years. This paper links together both topics by presenting a concept for the communication between vehicles and vulnerable road users, called Car2Pedestrian-Communication. A system architecture is presented that uses smartphones for the detection of vulnerable road users and for the transmission of data between the vehicle and the pedestrian. Based on the transmitted information, the collision risk between the vehicle and the pedestrian is estimated and a warning is given to the driver and the pedestrian.

Im Rahmen des Förderprogramms AUTONOMIK des Bundesministeriums für Wirtschaft und Technologie wurde in einem Konsortium aus neun Projektpartnern der Prototyp eines autonomen mobilen Roboters zur Gaslecksuche in ausgedehnten Industrieanlagen entwickelt. Anhand verschiedenartiger Sensorik zur Selbstlokalisation und Navigation wurde die autonome Beweglichkeit des Systems für beliebige Anlagen realisiert, mit der Option anhand von Teleoperation manuell in den Prozess einzugreifen. Ausgestattet mit Video- und Gasfernmesstechnik ist der Roboter imstande, Inspektionsaufgaben in Industrieanlagen durchzuführen, ohne in mögliche Gefahrenbereiche direkt einfahren zu müssen und ohne, dass ein Mensch vor Ort anwesend ist. Der Roboter kann zur routinemäßigen Inspektion von Anlagen oder zur gezielten Untersuchung spezifischer Anlagenteile eingesetzt werden. Dank der verwendeten Fernmesstechnik können auch Anlagenteile inspiziert werden, die aufgrund ihrer beschränkten Zugänglichkeit mittels herkömmlicher Messtechnik nur schwer zu inspizieren sind.

Teleoperationsunterstützung durch körpergekoppelte Steuerung und wahrnehmungsgerechtes visuelles Feedback. Hegenberg, J.; Cramar, L.; Schmidt, L. Boppard, 2013.
- [ Abstract ]
- [ BibSonomy-Post ]
Dieser Vortrag stellt verschiedene Ansätze zur Unterstützung eines menschlichen Operators bei der Teleoperation mobiler Roboter vor. Im Mittelpunkt steht dabei die Gestaltung der Schnittstelle zwischen Mensch und Roboter sowie insbesondere ihre Erweiterung durch geeignete Assistenzfunktionen. Durch Applikation eines benutzerzentrierten Gestaltungsansatzes nach ISO 9241-210 [1, 2, 3] und dabei insbesondere durch Evaluationen mit potentiellen Nutzern wird außerdem die Gebrauchstauglichkeit und Akzeptanz prototypisch realisierter Interaktionskonzepte sichergestellt. Dazu werden ausgewählte Evaluationsergebnisse vorgestellt. Unterstützungsbedarf hinsichtlich der Teleoperation besteht sowohl im Bezug auf die Wahrnehmung der entfernten Einsatzumgebung durch den Operator als auch im Bezug auf die Steuerung einer potentiell großen Anzahl an Freiheitsgraden des mobilen Robotersystems. Beide Aspekte führen zu hohen Anforderungen an die kognitiven und motorischen Fähigkeiten des Operators, denen es durch geeignete technische Lösungen zu begegnen gilt. Zur Evaluation verschiedener Assistenzsysteme zur Teleoperationsunterstützung wurde eine mobile Roboterplattform aufgebaut, die mit Hilfe eines Roboterarms und eines Drei-Finger-Greifers manipulativ auf ihre Einsatzumgebung einwirken kann. Da der Roboter außerdem in der Lage ist, autonom zu navigieren, lassen sich über reine Teleoperation hinausgehende Interaktionskonzepte wie bspw. die leitende Kontrolle [4] eines Mensch-Roboter-Systems untersuchen. Zur Unterstützung der Wahrnehmung der entfernten Umgebung wurde der Roboter mit einem Stereokamerasystem ausgestattet, dessen technische Auslegung sich an den Eigenschaften des visuellen Systems des Menschen orientiert [5] und somit eine möglichst natürliche Wahrnehmung bietet. Ähnliche Arbeiten fokussieren oft auf die technische Realisierung oder auf maschinelles Sehen. Stereoskopie ermöglicht dem Operator eine Tiefenwahrnehmung, die zur Durchführung von Telemanipulationsaufgaben notwendig ist. Das Kamerasystem ist schwenk- und neigbar, ermöglicht eine servobasierte Nachführung der Augenvergenz und lässt sich bspw. durch Einstellung des Pupillenabstandes an verschiedene Nutzer anpassen. Zur Visualisierung der Videobilder werden stereoskopische Bildschirme und ein Head-Mounted Display eingesetzt. Aktuelle Arbeiten bzgl. der Visualisierung beschäftigen sich mit 3D-Laser-basierten Umgebungsmodellen als Ersatz für Videobilder und Augmented Reality. Um den Operator bei der Steuerung der verschiedenen Freiheitsgrade des Systems zu unterstützen, wurden Ansätze erprobt, die Freiheitsgrade an die Bewegung des Operators zu koppeln. Ein Beispiel dafür ist die Steuerung der Ausrichtung des Kamerasystems entsprechend der Kopfbewegung des Operators [6, 7]. Dies wurde hier für visuelle Suchaufgaben eingesetzt, die gegenüber anderen Anwendungen größere und häufigere Kopfbewegungen erfordern. Außerdem wurden verschiedene publizierte Realisierungsansätze bzgl. ihrer Auswirkungen auf den Menschen vergleichend untersucht. Ein weiteres Beispiel ist die Verfolgung der Handbewegung des Operators. Diese wird häufig zum Teachin automatischer Bewegungsabläufe eingesetzt, selten zur Teleoperation. Teilkomponenten haben in ersten Evaluationen ihre Überlegenheit gegenüber herkömmlichen Ansätzen unter Beweis gestellt [8]. Aktuelle Arbeiten in diesem Bereich beschäftigen sich mit symbolischen Ansätzen zur Gestensteuerung des Robotersystems.

Communities are a central aspect in the formation of social interaction networks. In this paper, we analyze the evolution of communities in networks of face-to-face proximity. As our application context, we consider four scientific conferences. We compare the basic properties of the contact graphs to describe the properties of the contact networks and analyze the resulting community structure using state-of-the-art automic community detection algorithms. Specifically, we analyze the evolution of contacts and communities over time to consider the stability of the respective communities. In addition, we assess different factors which have an influence on the quality of community prediction. Overall, we provide first important insights into the evolution of contacts and communities in face-to-face contact networks.

- [ Abstract ]
- [ BibSonomy-Post ]
Im Rahmen der Evaluation einer ubiquitären Anwendung wird in der Regel auch die Erfüllung der Sicherheitsanforderungen durch Sicherheits-Spezialisten überprüft. In einem rein disziplinären Vorgehen wird dies vollständig unabhängig von den anderen Disziplinen z.B. Benutzervertrauen oder rechtliche Anforderungen durchgeführt. Die dabei entdeckten Sicherheitsmängel berücksichtigen häufig nicht die Endnutzer und können Auswirkung auf andere Disziplinen haben. Daher schlagen wir in diesem Beitrag eine neue interdisziplinäre Sicherheitsanalyse vor, welche den Endnutzer und die Abhängigkeiten zu anderen Disziplinen berücksichtigt. Dies erreichen wir, indem wir jeden Schritt der klassischen Sicherheitsanalyse interdisziplinär durchführen und erkannte Bedrohungen während einer Systemevaluation als konkrete Angriffe simulieren. Darüber hinaus zeigen wir die konkrete Anwendung unserer interdisziplinären Sicherheitsanalyse am Beispiel einer prototypischen Anwendung.

Adaptive applications constitute the basis for many ubiquitous computing scenarios as they can dynamically adapt to changing contexts. The usability design principles transparency, controllability, and consistency have been recommended for the design of adaptive interfaces. However, designing self-adaptive applications that may act completely autonomous is still a challenging task because there is no set of usability design guidelines. Applying the three principles in the design of the five different adaptations of the mobile adaptive application Meet-U revealed as difficult. Based on an analysis of the design problem space, we elaborate an approach for the design of usable adaptations. Our approach is based on a notification design concept which calculates the attention costs and utility benefits of notified adaptations by varying the design aspects transparency and controllability. We present several designs for the adaptations of Meet\hbox{-}}U. The results of a user study shows that the notification design approach is beneficial for the design of adaptations. Varying transparency and controllability is necessary to adjust an adaptation’s design to the particular context of use. This leads to a partially inconsistent design for adaptations within an application.

Ein technisches Assistenzsystem für den Computerarbeitsplatz könnte dabei unterstützen, physische und psychische Beanspruchungen zu mindern, indem es sensorbasiert erfasst, wenn eine übermäßige Beanspruchung vorliegt und Gegenmaßnahmen in einer adäquaten Weise vorschlägt. Auch könnte es möglichen Beanspruchungen vorbeugen. Im Projekt "Smart Seating" wurden verschiedene Bestandteile des beschriebenen Assistenzsystems im Rahmen des benutzerzentrierten Gestaltungsansatzes unter Einbezug der potentiellen Nutzer konzipiert oder prototypisch entwickelt. Dieser Beitrag stellt die Einzelarbeiten und die jeweiligen Erkenntnisse für die Entwicklung des Assistenzsystems vor.

The information contained in social tagging systems is often modelled as a graph of connections between users, items and tags. Recommendation algorithms such as FolkRank, have the potential to leverage complex relationships in the data, corresponding to multiple hops in the graph. We present an in-depth analysis and evaluation of graph models for social tagging data and propose novel adaptations and extensions of FolkRank to improve tag recommendations. We highlight implicit assumptions made by the widely used folksonomy model, and propose an alternative and more accurate graph-representation of the data. Our extensions of FolkRank address the new item problem by incorporating content data into the algorithm, and significantly improve prediction results on unpruned datasets. Our adaptations address issues in the iterative weight spreading calculation that potentially hinder FolkRank's ability to leverage the deep graph as an information source. Moreover, we evaluate the benefit of considering each deeper level of the graph, and present important insights regarding the characteristics of social tagging data in general. Our results suggest that the base assumption made by conventional weight propagation methods, that closeness in the graph always implies a positive relationship, does not hold for the social tagging domain.

Onomastics is "the science or study of the origin and forms of proper names of persons or places." ["Onomastics". Merriam-Webster.com, 2013. http://www.merriam-webster.com (11 February 2013)]. Especially personal names play an important role in daily life, as all over the world future parents are facing the task of finding a suitable given name for their child. This choice is influenced by different factors, such as the social context, language, cultural background and, in particular, personal taste. With the rise of the Social Web and its applications, users more and more interact digitally and participate in the creation of heterogeneous, distributed, collaborative data collections. These sources of data also reflect current and new naming trends as well as new emerging interrelations among names. The present work shows, how basic approaches from the field of social network analysis and information retrieval can be applied for discovering relations among names, thus extending Onomastics by data mining techniques. The considered approach starts with building co-occurrence graphs relative to data from the Social Web, respectively for given names and city names. As a main result, correlations between semantically grounded similarities among names (e.g., geographical distance for city names) and structural graph based similarities are observed. The discovered relations among given names are the foundation of "nameling" [http://nameling.net], a search engine and academic research platform for given names which attracted more than 30,000 users within four months, underpinningthe relevance of the proposed methodology.

All over the world, future parents are facing the task of finding a suitable given name for their child. This choice is influenced by different factors, such as the social context, language, cultural background and especially personal taste. Although this task is omnipresent, little research has been conducted on the analysis and application of interrelations among given names from a data mining perspective. The present work tackles the problem of recommending given names, by firstly mining for inter-name relatedness in data from the Social Web. Based on these results, the name search engine "Nameling" was built, which attracted more than 35,000 users within less than six months, underpinning the relevance of the underlying recommendation task. The accruing usage data is then used for evaluating different state-of-the-art recommendation systems, as well our new NR algorithm which we adopted from our previous work on folksonomies and which yields the best results, considering the trade-off between prediction accuracy and runtime performance as well as its ability to generate personalized recommendations. We also show, how the gathered inter-name relationships can be used for meaningful result diversification of PageRank-based recommendation systems. As all of the considered usage data is made publicly available, the present work establishes baseline results, encouraging other researchers to implement advanced recommendation systems for given names.

With the rising popularity of smart mobile devices, sensor data-based applications have become more and more popular. Their users record data during their daily routine or specifically for certain events. The application WideNoise Plus allows users to record sound samples and to annotate them with perceptions and tags. The app is being used to document and map the soundscape all over the world. The procedure of recording, including the assignment of tags, has to be as easy-to-use as possible. We therefore discuss the application of tag recommender algorithms in this particular scenario. We show, that this task is fundamentally different from the well-known tag recommendation problem in folksonomies as users do no longer tag fix resources but rather sensory data and impressions. The scenario requires efficient recommender algorithms that are able to run on the mobile device, since Internet connectivity cannot be assumed to be available. Therefore, we evaluate the performance of several tag recommendation algorithms and discuss their applicability in the mobile sensing use-case.

Especially in urban areas, mobility concepts that only take into account individual modes of transport are reaching spatial and ecological limits [6]. In this regard, the linkage of individual modes of transport in form of intermodal services is considered as sustainable alternative. However, Current intermodal approaches are usually designed for local population. Since urban tourism shows high growth rates with a private transport share of nearly 70%, touristic traffic does not represent an underestimated proportion of urban traffic [3]. For this reason, within the "FREE" research project, an intermodal service especially for urban tourists will be developed, which will be bookable together with accommodations, arrivals and departures in the pre-trip phase of the journey. To support tourists during trips in foreign environments, an application for mobile devices will also be developed. To provide a requirements framework as part of a user-centred design process according to DIN EN ISO 9241-210 [12], 26 mobile applications (public transport, bike- and car sharing and intermodal services) and 12 web-based booking systems (providing the reservation of accommodations together with arrival and departure options) were analysed concerning their functional standard and usability. It was found that web-based booking systems provide uniformed templates for booking processes of accommodations, arrival and departure modules. In terms of further bookings no consistent pattern was found. For mobile applications, it was found that in addition to functions concerning orientation and navigation, the purchase of tickets respectively the reservation of vehicles is provided. To support the user in the mobile context of use, context-sensitive reminder and notification features are also provided. With the analysis of user feedback could be determined that today’s systems show negative impact on user-experience by providing unreliable real-time information and by access to personal user data. To take into account the touristic background of "FREE", furthermore a persona based scenario workshop with 9 experts (3 tourism experts, 3 traffic planners, 2 human factors experts and one provider of rental bikes) was conducted. The findings uncovered that in contrast to current intermodal systems, a touristic approach should supply uniformed access to all modes of transport as well as predefined routes linked with touristic sights.

Understanding the process of link creation is rather important for link prediction in social networks. Therefore, this paper analyzes contact structures in networks of face-to-face spatial proximity, and presents new insights on the dynamic and static contact behavior in such real world networks. We focus on face-to-face contact networks collected at different conferences using the social conference guidance system Conferator. Specifically, we investigate the strength of ties and its connection to triadic closures in face-to-face proximity networks. Furthermore, we analyze the predictability of all, new and recurring links at different points of time during the conference. In addition, we consider network dynamics for the prediction of new links.

The processing capabilities of current smartphones have increased significantly. We propose a distributed and collaborative context prediction approach that exclusively uses current smartphones to automatically collect, process and predict contexts of users. To predict a user's next context, not only her context history is utilised but also context histories of other users are used. The communication between the smartphones of the users is realised using peer-2-peer. Therefore, no centralised server unit is needed to process the context information of the users externally. We provide a proof-of-concept implementation and present experimental results that demonstrate the practicality of the proposed architecture.

Software development has proven to be a challenge. To address this challenge, there are quite many interesting approaches how to develop software - starting from the waterfall approach, up to recently quite popular agile software development techniques. Another already some years old approach was described by the Gang of Four and proposes the usage of design patterns to provide a general reusable solution to commonly occurring problems in software development. Although design patterns have been around for a long time, their usability is still promising. To the best of our knowledge "interdisciplinary patterns" to address challenges in the development of context aware application in ubiquitous environments have not been described in literature so far. Hence, this paper proposes and also evaluates concrete interdisciplinary software development patterns. To provide an application example the proposed patterns are used to address two use cases that commonly occur in the development process of context aware applications: providing transparency to the user and ensuring a user’s self-determination. For the demonstration of the patterns Support-U a context aware application that provides elderly people to live autonomously is used.

Social Tagging Systems are web applications in which users upload resources (e.g., bookmarks, videos, photos, etc.) and annotate it with a list of freely chosen keywords called tags. This is a grassroots approach to organize a site and help users to find the resources they are interested in. Social tagging systems are open and inherently social; features that have been proven to encourage participation. However, with the large popularity of these systems and the increasing amount of user-contributed content, information overload rapidly becomes an issue. Recommender Systems are well known applications for increasing the level of relevant content over the “noise” that continuously grows as more and more content becomes available online. In social tagging systems, however, we face new challenges. While in classic recommender systems the mode of recommendation is basically the resource, in social tagging systems there are three possible modes of recommendation: users, resources, or tags. Therefore suitable methods that properly exploit the different dimensions of social tagging systems data are needed. In this book, we survey the most recent and state-of-the-art work about a whole new generation of recommender systems built to serve social tagging systems. The book is divided into self-contained chapters covering the background material on social tagging systems and recommender systems to the more advanced techniques like the ones based on tensor factorization and graph-based models.

Industrial plants are a vital and common asset of modern society in a various number of ways. Safety of large industrial complexes that handle hazardous chemical materials is of utter importance to prevent harm to employees, general population, our natural environment and valuable infrastructure. Therefore, beside the plant owner’s own financial interest to guarantee faultless and safe operation, legal regulations have to be adhered due to strong public interest as well. An important measure to ensure safety is the implementation of regular inspection tours by maintenance personnel, who examine the often widely-stretched process infrastructure on foot and locally search for signs of beginning leakage. The Research Project RoboGasInspector was started to develop new means of aiding with the fulfillment of this essential task. This article gives an insight into this ongoing research project, where autonomous mobile robotics is combined with laser-based remote gas detection technology in order to create a proof-of-concept inspection system prototype, which can relieve humans of this monotonous and highly repetitive work.

To facilitate user-centered software engineering, developers need an easy to grasp understanding of the user. The use of personas helps to keep specific user needs in mind during the design process. Technology acceptance is of particular interest for the design of innovative applications previously unknown to potential users. Therefore, our research focuses on defining a typology of relevant user characteristics with respect to technology acceptance and transferring those findings to the description of personas. The presented work focuses on the statistical relationship between technology acceptance and personality. We apply sub-group discovery as a statistical tool. Based on the statistically derived subgroups and patterns we define the mentioned personas to help developers to understand different forms of technology acceptance. By integrating the specifically defined personas into existing methods in the field of software engineering the feasibility of the presented approach is demonstrated.

Zu einer sozialverträglichen Technikgestaltung neuartiger Smartphone-Anwendungen gehört es, die Bedürfnisse unterschiedlicher Nutzergruppen zu berücksichtigen. Dieser Beitrag stellt die Kasseler Entwicklungsmethodik vor, die darauf ausgerichtet ist, softwarebasierte Systeme sozialverträglich zu gestalten und im Rahmen der Zusammenarbeit im Forschungsprojekt VENUS gemeinsam entworfen wird. Die koordinierte Zusammenarbeit von Experten aus den Bereichen Informatik, Rechts- und Wirtschaftswissenschaften sowie Ergonomie im Rahmen der Kasseler Methodik wird im Folgenden am Beispiel der Gestaltung der Smartphone Applikation Meet-U dargestellt. Dabei wird das Entwicklungsergebnis mit Kasseler Methodik (Meet-U-A) im Rahmen einer Evaluation der Nutzerakzeptanz mit einer Version B der Anwendung (Meet-U-B) verglichen, die ohne Kasseler Methodik entwickelt wurde. Die Auswertung der Evaluationen (n=150 bzw. n=153) erfolgte mit dem Ziel, die folgende Hypothese zu prüfen: Die Entwicklung nach Kasseler Methodik führt zu einer höheren Akzeptanz bei einer relativ technikfernen Nutzergruppe. Für die technikfernen Personen konnte tatsächlich eine signifikante Erhöhung der Akzeptanz von etwa 50% (Meet-U-B) auf 70% (Meet-U-A) festgestellt werden. Die Ergebnisse der Evaluationen werden bezogen auf ihre Aussagekraft für die Qualität der Kasseler Methodik diskutiert.

A major challenge for ubiquitous system design is creating applications that are legal-compatible and accepted by their intended users. Today’s European data protection principles contradict the ideas of ubiquitous computing. Additionally, users have to deal with unconventional interaction concepts leading to a low amount of trust and acceptance in such systems. Current development approaches do not sufficiently cover these concerns, as they do not systematically incorporate expertise from the relevant disciplines. We present a novel development approach for ubiquitous systems that explicitly addresses these concerns. Our primary task was to manage the increased number of stakeholders and dependencies, respectively conflicts between requirements of the particular disciplines. The approach incorporates predefined artifacts and a defined workflow with responsibilities, as well as suggesting how to develop mutual understanding. We apply this multidisciplinary approach to develop the ubiquitous application Meet-U.

Vorwissen, das die Grundlage einer intuitiven Interaktion darstellt, kann verschiedene Quellen haben. Gesten, die zur Steuerung eines mobilen Roboters herangezogen werden können, können ihren Ursprung in Alltagserfahrungen haben, wie beispielsweise dem Wegweisen, und werden durch die relativ häufige Verwendung meistens unbewusst angewendet. Im Gegensatz dazu kann die Verwendung von erlernten Gesten, die nicht zum intuitiven Gestenvokabular gehören, eine potentielle Fehlerquelle darstellen. In einem Experiment mit zehn Versuchspersonen wurden im ersten Durchlauf intuitive Gesten ermittelt, um im zweiten Versuchsdurchlauf durch erlernte Gesten ersetzt zu werden. Die Durchführungszeit sowie die Anzahl der Kollisionen und der Abweichungen von den vorgegebenen Gesten wurden dabei ermittelt und dienten als Effizienz- und Zuverlässigkeitsindikatoren. Im Ergebnis wurden Empfehlungen für die Auswahl von Gesten zur Steuerung mobiler Roboter abgeleitet.

Eine wesentliche Voraussetzung für die Aufrechterhaltung des Situationsbewusstseins ist die korrekte Wahrnehmung und Interpretation der Umgebung mit ihren Elementen und Veränderungen. Die entscheidende Rolle spielen dabei die Umgebungsreize, die der Mensch unmittelbar aufnehmen kann. Im Fall einer Fernüberwachung, die über eine Benutzungsschnittstelle und damit indirekt erfolgt, kann die Wahrnehmung beispielsweise aufgrund des eingeschränkten Sichtfeldes, der Qualität übertragener Videodaten und der Tatsache, dass nur ein Teil menschlicher Modalitäten angesprochen wird, wesentlich beeinträchtigt werden. Durch eine gezielte Gestaltung der Benutzungsschnittstelle und die gezielte Entwicklung von Assistenzfunktionen zur Aufrechterhaltung des Situationsbewusstseins soll diesen Herausforderungen bei der Überwachung autonomer mobiler Roboter begegnet werden.

The ever-growing flood of new scientific articles requires novel retrieval mechanisms. One means for mitigating this instance of the information overload phenomenon are collaborative tagging systems, that allow users to select, share and annotate references to publications. These systems employ recommendation algorithms to present to their users personalized lists of interesting and relevant publications. In this paper we analyze different ways to incorporate social data and metadata from collaborative tagging systems into the graph-based ranking algorithm FolkRank to utilize it for recommending scientific articles to users of the social bookmarking system BibSonomy. We compare the results to those of Collaborative Filtering, which has previously been applied for resource recommendation.

Adaptive applications establish the basis for many ubiquitous computing scenarios as they can dynamically adapt to changing contexts. But adaptive applications lack of success when the adaptive behaviour does not correspond to the user’s interaction habits. A user study revealed that such applications are not satisfying for complex scenarios with a high degree of user interaction. We claim that there must be a trade-off between automation and user participation. By extending an existing adaptation middleware with capabilities to respect user preference and interaction behaviour we demonstrate how to integrate the user in the self-adaptation loop. Interdisciplinary results from the fields of usability engineering and interaction design include the need for an adaptation notification concept to avoid mismatching adaptation behaviour.

The focus of this paper is on context-aware, selfadaptive ubiquitous computing applications that involve mobile users. The development of such applications is inherently complex for two main reasons: From a technical perspective, context management and adaptation management add complexity to the application design and implementation. From a socio-technical perspective, concerns and requirements related to the social embedding and user acceptance must be addressed in the application design and lead to additional complexity, particularly because sensitive personal data is collected, processed, stored and communicated by such applications. In this position paper we present an analysis of the problem space and a solution approach. We have developed an interdisciplinary methodology that systematically addresses technical as well as non-technical concerns. Our conclusion is that solving the socio-technical challenges will be a key enabler for ubiquitous computing.

Lots of industrial plants are regularly inspected for irregularities such as gas leaks. This is done by plant personnel via visual, aural, olfactory, and gas detector based search. Mobile robots equipped with several sensors are an opportunity to free personnel from this monotone repetitive task. A task- and user-centered design approach was chosen to assure an efficient and effective human-robot interaction and to enhance the acceptance of the developed human-machine system. In the first step, current practices were surveyed and analyzed. Then, system requirements were derived and technically realized, to iteratively evaluate their usability. This article illustrates this design approach by exemplarily presenting requirements and their realization.

Dieser Beitrag beschreibt anhand eines konkreten Anwendungsfalls aus dem Bereich der Robotik, wie die Fähigkeiten des Menschen bei der Gestaltung einer Head-Mounted-Display-basierten Mensch-Roboter-Schnittstelle technisch umgesetzt werden können. Den inhaltlichen Rahmen bildet das Forschungsprojekt RoboGasInspector, dessen Ziel es ist, ein innovatives Mensch-Maschine-System mit mobilen und mit Gasfernmesstechnik ausgestatteten Inspektionsrobotern zu entwickeln und zu evaluieren, welches die Detektion und Ortung von Gaslecks in räumlich ausgedehnten technischen Anlagen weitgehend autonom bewältigt. Nach aktuellem Stand von Forschung und Entwicklung kann ein technisches System insbesondere in dynamischen Umgebungen nicht absolut fehlerfrei und ausfallsicher realisiert werden. Aus Gründen der Akzeptanz und der Anlagensicherheit ist deshalb eine Überwachung der mobilen Roboter erforderlich, die sich teilautonom durch die Anlage bewegen. Das Systemkonzept sieht eine zentrale Leitwarte mit zwei Benutzungsschnittstellen vor. Die eine Schnittstelle dient der Planung, Überwachung und Dokumentation der autonomen Funktion des Systems und die andere der Teleoperation des Roboters durch einen menschlichen Operator. Die Teleoperation soll menschliche Fähigkeiten synergetisch in das weitgehend automatisierte System integrieren und wird eingesetzt, falls der Mensch in der Lage ist, bei der Bearbeitung einer Aufgabe bessere Ergebnisse zu erzielen. Zur Unterstützung der Teleoperation wird ein Assistenzsystem eingesetzt, das dem Operator die visuellen Informationen liefert, die er benötigt um bei der Steuerung des Roboters am entfernten Einsatzort sein Situationsbewusstsein aufrechtzuerhalten. Das Assistenzsystem besteht aus einem Head-Mounted Display zur Ausgabe augmentierter Videobilder, die von einem Stereokamerasystem auf dem Roboter aufgezeichnet werden. Die Gestaltung der Teleoperationsunterstützung zielt darauf ab, dem Nutzer das Gefühl zu vermitteln mit den eigenen Augen aus der Perspektive des Roboters zu sehen bzw. im Sinne einer Telepräsenz selber vor Ort zu sein. Dazu wird bei der technischen Umsetzung von den menschlichen Fähigkeiten ausgegangen. Analogien zwischen technischen Parametern und quantitativen Maßen menschlicher Fähigkeiten werden genutzt, in dem die Parameter den zugehörigen Maßen angenähert werden. Eine Auswahl dieser Analogien wird in diesem Beitrag wiedergegeben und die Nachempfindung der menschlichen Wahrnehmung und Motorik durch Gegenüberstellung quantitativer Wertpaare beurteilt.

Originally introduced by social bookmarking systems, collaborative tagging, or social tagging, has been widely adopted by many web-based systems like wikis, e-commerce platforms, or social networks. Collaborative tagging systems allow users to annotate resources using freely chosen keywords, so called tags . Those tags help users in finding/retrieving resources, discovering new resources, and navigating through the system. The process of tagging resources is laborious. Therefore, most systems support their users by tag recommender components that recommend tags in a personalized way. The Discovery Challenges 2008 and 2009 of the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD) tackled the problem of tag recommendations in collaborative tagging systems. Researchers were invited to test their methods in a competition on datasets from the social bookmark and publication sharing system BibSonomy. Moreover, the 2009 challenge included an online task where the recommender systems were integrated into BibSonomy and provided recommendations in real time. In this chapter we review, evaluate and summarize the submissions to the two Discovery Challenges and thus lay the groundwork for continuing research in this area.

Real-world tagging datasets have a large proportion of new/ untagged documents. Few approaches for recommending tags to a user for a document address this new item problem, concentrating instead on artificially created post-core datasets where it is guaranteed that the user as well as the document of each test post is known to the system and already has some tags assigned to it. In order to recommend tags for new documents, approaches are required which model documents not only based on the tags assigned to them in the past (if any), but also the content. In this paper we present a novel adaptation to the widely recognised FolkRank tag recommendation algorithm by including content data. We adapt the FolkRank graph to use word nodes instead of document nodes, enabling it to recommend tags for new documents based on their textual content. Our adaptations make FolkRank applicable to post-core 1 ie. the full real-world tagging datasets and address the new item problem in tag recommendation. For comparison, we also apply and evaluate the same methodology of including content on a simpler tag recommendation algorithm. This results in a less expensive recommender which suggests a combination of user related and document content related tags.</p><p>Including content data into FolkRank shows an improvement over plain FolkRank on full tagging datasets. However, we also observe that our simpler content-aware tag recommender outperforms FolkRank with content data. Our results suggest that an optimisation of the weighting method of FolkRank is required to achieve better results.

Even though computers play a massive role in everyday life of modern societies, older adults, and especially older women, are less likely to use a computer, and they perform fewer activities on it than younger adults. To get a better understanding of the factors affecting older adults’ intention towards and usage of computers, the Unified Theory of Acceptance and Usage of Technology (UTAUT) was applied as part of a more extensive study with 52 users and non-users of computers, ranging in age from 50 to 90 years. The model covers various aspects of computer usage in old age via four key constructs, namely performance expectancy, effort expectancy, social influences, and facilitating conditions, as well as the variables gender, age, experience, and voluntariness it. Interestingly, next to performance expectancy, facilitating conditions showed the strongest correlation with use as well as with intention. Effort expectancy showed no significant correlation with the intention of older adults to use a computer.

VertrauensaufbauundVertrauensunterstützungsinderfolgskritischfürdieAd- option neuer IT-Systeme. Umso erstaunlicher ist, dass in der Literatur kaum etwas zur systematischen Integration der Vielzahl an verhaltensorientierten Erkenntnissen zu Vertrauen in und um IT-Systeme in deren Entwicklung zu finden ist. Das Ziel dieses Artikels ist die Entwicklung einer Methode zur Ableitung vertrauensunterstützender Komponenten für sozio-technische ubiquitäre Systeme. Die Methode wird exemplarisch auf die Entwicklung einer ubiquitären Restaurantempfehlungsanwen- dung angewandt. Die Anwendung wird hierdurch um vier vertrauensunterstützende Komponenten angereichert. Die so entwickelte Anwendung wird anschließend im Rahmen eines Laborexperiments mit 166 Probanden evaluiert. Hierbei wird gezeigt, dass sowohl das Vertrauen in das sozio-technische ubiquitäre System, als auch die Absicht es zu nutzen signifikant erhöht werden konnten. Soweit es den Autoren bekannt ist, beschreibt dieser Artikel als Erster, wie Vertrauen in systematischer Art und Weise in die Entwicklung sozio-technischer ubiquitärer Systeme einbezogen werden und welchen Nutzen dies stiften kann.

Sensors built into current smartphones or in modern facilities are becoming ubiquitous and influence our daily lives more and more. Hence, services that proactively adapt their behaviour to the user's needs is no longer a vision of the future. The proactiveness of such services is achieved by using context prediction algorithms. These algorithms are primarily applied to personal context data of a user, for example to user's motion activities or even to complete daily routines in order to predict a user's next context. Due to this fact the paper presents the most significant legal criteria that have to be considered by the prediction approaches while using personal context data. Following, the criteria are used to legally assess the context prediction approaches. Finally, the resulting consequences are discussed.

Tragically, traffic accidents involving pedestrians or cyclists cause thousands of fatalities and serious injuries world- wide every year. Therefore, improving the safety of vulnerable road users is an international priority. One key challenge in designing an "ideal" protection system is to filter the endangered pedestrians out of potentially many. In this paper, we present a novel approach to proactively filter those pedestrians whose very next step would bring them (dangerously) closer to the street so as to provide an extra and crucial time advantage for a collision avoidance system. To predict a pedestrian's next step, we use the Collaborative Context Predictor. It takes advantage of collaborative behaviour patterns, in this case the movement patterns of the pedestrians. As well, a comparison with two state of the art context prediction approaches is carried out. The comparison is performed using real measured movement data, which is received from a smartphone the pedestrians carry in their trouser pocket.

The new generation of Web applications known as (STS) is successfully established and poised for continued growth. STS are open and inherently social; features that have been proven to encourage participation. But while STS bring new opportunities, they revive old problems, such as information overload. Recommender Systems are well known applications for increasing the level of relevant content over the noise that continuously grows as more and more content becomes available online. In STS however, we face new challenges. Users are interested in finding not only content, but also tags and even other users. Moreover, while traditional recommender systems usually operate over 2-way data arrays, STS data is represented as a third-order tensor or a hypergraph with hyperedges denoting (user, resource, tag) triples. In this chapter, we survey the most recent and state-of-the-art work about a whole new generation of recommender systems built to serve STS.We describe (a) novel facets of recommenders for STS, such as user, resource, and tag recommenders, (b) new approaches and algorithms for dealing with the ternary nature of STS data, and (c) recommender systems deployed in real world STS. Moreover, a concise comparison between existing works is presented, through which we identify and point out new research directions.

Die Entwickler von Anwendungen zur technisch-sozialen Vernetzung stehen vor der Herausforderung einerseits nützliche und andererseits sichere und kontrollierbare Lösungen zu finden, um die Akzeptanz der späteren Nutzer sicherzustellen. In diesem Beitrag beschreiben wir einen benutzerorientierten Entwicklungsprozess für die RFID-basierte Anwendung MyGroup, die für die Kooperationsunterstützung am Arbeitsplatz (engl Computer Supported Cooperative Work, CSCW) eingesetzt wird. Dabei konzentrieren wir uns auf die frühen Phasen der benutzerorientierten Entwicklung und stellen einen Ansatz vor, der die Anforderungsanalyse mit Befragungen zur Nutzerakzeptanz auf der Grundlage eines theoretischen Szenarios verbindet.

Recent research has demonstrated how the widespread adoption of collaborative tagging systems yields emergent semantics. In recent years, much has been learned about how to harvest the data produced by taggers for engineering light-weight ontologies. For example, existing measures of tag similarity and tag relatedness have proven crucial step stones for making latent semantic relations in tagging systems explicit. However, little progress has been made on other issues, such as understanding the different levels of tag generality (or tag abstractness), which is essential for, among others, identifying hierarchical relationships between concepts. In this paper we aim to address this gap. Starting from a review of linguistic definitions of word abstractness, we first use several large-scale ontologies and taxonomies as grounded measures of word generality, including Yago, Wordnet, DMOZ and Wikitaxonomy. Then, we introduce and apply several folksonomy-based methods to measure the level of generality of given tags. We evaluate these methods by comparing them with the grounded measures. Our results suggest that the generality of tags in social tagging systems can be approximated with simple measures. Our work has implications for a number of problems related to social tagging systems, including search, tag recommendation, and the acquisition of light-weight ontologies from tagging data.

With the increased popularity of Web 2.0 services in the last years data privacy has become a major concern for users. The more personal data users reveal, the more difficult it becomes to control its disclosure in the web. However, for Web 2.0 service providers, the data provided by users is a valuable source for offering effective, personalised data mining services. One major application is the detection of spam in social bookmarking systems: in order to prevent a decrease of content quality, providers need to distinguish spammers and exclude them from the system. They thereby experience a conflict of interests: on the one hand, they need to identify spammers based on the information they collect about users, on the other hand, they need to respect privacy concerns and process as few personal data as possible. It would therefore be of tremendous help for system developers and users to know which personal data are needed for spam detection and which can be ignored. In this paper we address these questions by presenting a data privacy aware feature engineering approach. It consists of the design of features for spam classification which are evaluated according to both, performance and privacy conditions. Experiments using data from the social bookmarking system BibSonomy show that both conditions must not exclude each other.

In universal algebra and in lattice theory the notion of varieties is very prominent, since varieties describe the classes of all algebras (or of all lattices) modeling a given set of equations. While a comprehensive translation of that notion to a similar notion of varieties of complete lattices – and thus to Formal Concept Analysis – has not yet been accomplished, some characterizations of the doubly founded complete lattices of some special varieties (e.g. the variety of modular or that of distributive lattices) have been discovered. In this paper we use the well-known arrow relations to give a characterization of the formal contexts of doubly founded concept lattices in the variety that is generated by M 3 – the smallest modular, non-distributive lattice variety.

In today's increasingly mobile society, car manufacturers and suppliers worldwide face the imperative requirement and have already been working to reduce the number of people killed in traffic accidents. In this context pedestrian protection respectively collision avoidance between cars and pedestrians is of vital importance. Several approaches exist to detect pedestrians but only a few of them are able to work without line of sight and/ or only have a very brief view of the movement history of the pedestrian. However, radio communication based systems which exchange GPS based position information of the pedestrian and the car might have a detailed view to the movement history but the update frequency of GPS positions provided by the mobile phone reduces the speed of the system and might induce false alarms. In this paper, the additional use of pedestrian movement recognition using an acceleration sensor implemented in a mobile phone in the area of collision avoidance between cars and pedestrian is presented and a performance analysis is carried out using the results of an experiment. Finally, the benefits of this approach to the reduction of false alarms and detection of endangered pedestrians are discussed.

Recommendation algorithms and multi-class classifiers can support users of social bookmarking systems in assigning tags to their bookmarks. Content based recommenders are the usual approach for facing the cold start problem, i.e., when a bookmark is uploaded for the first time and no information from other users can be exploited. In this paper, we evaluate several recommendation algorithms in a cold-start scenario on a large real-world dataset.

Context aware applications are reactive, they adapt to an entity’s context when the context has changed. In order to become proactive and act before the context actually has changed future contexts have to be predicted. This will enable functionalities like preloading of content or detection of future conflicts. For example if an application can predict where a user is heading to it can also check for train delays on the user’s way. So far research concentrates on context prediction algorithms that only use a history of one context to predict the future context. In this paper we propose a novel multidimensional context prediction algorithm and we show that the use of multidimensional context histories increases the prediction accuracy. We compare two multidimensional prediction algorithms, one of which is a new approach; the other was not yet experimentally tested. In theory, simulation and a real world experiment we verify the feasibility of both algorithms and show that our new approach has at least equal or better reasoning accuracy.

Das Thema Augmented Reality kann insbesondere vor dem Hintergrund der benutzerzentrierten Gestaltung fruchtbar gemacht werden: Beginnend beim ersten großen deutschen Mensch-Technik-Interaktions-Leitprojekt "ARVIKA - Augmented Reality für Entwicklung, Produktion und Service", über Projekte zur Unterstützung von Schweißprozessen im Schiffsbau und Anwendungen in der Medizintechnik, ergonomische Untersuchungen zu Head-Mounted Displays bis hin zur Überwachung technischer Anlagen mit mobilen Inspektionsrobotern stehen dabei methodisch stets die Benutzer und ihre Aufgaben im Zentrum der Gestaltung. Der Vortrag umfasst einen Querschnitt aus verschiedenen Projekten und stellt in diesem Kontext Methoden zur benutzerzentrierten Gestaltung von Augmented-Reality-Systemen vor.

- [ BibSonomy-Post ]
Ubiquitäre Anwendungen brechen mit den klassischen Interaktionsformen zwischen Mensch und Informationstechnologie (IT). Rechner, Maus und Tastatur stehen nicht länger auf dem Schreibtisch - die IT verschmilzt mit Gebrauchsgegenständen und Umgebungen und unterstützt den Menschen aus dem Hintergrund. Der Mensch interagiert mit der eingebetteten Technologie implizit, ohne einen Bruch zu seinen IT-unabhängigen Handlungen in der Welt zu erleben. Sensorik misst, Prozessoren entscheiden und Aktuatorik bewirkt, ohne dass der Mensch direkt steuert und bedient. Diese zunehmend real werdende Vision verändert das System Mensch-Maschine. Es erfolgt eine Verschiebung der aktiven und die Interaktion steuernden Impulse hin zur Technik. Die veränderten Interaktionsparadigmen führen unter anderem zu den Fragen, ob die im benutzerorientierten Entwicklungsprozess bewährten Methoden noch geeignet sind, ob diese anzupassen sind oder ob gänzlich neue Formen benötigt werden. Berührt davon ist der gesamte Gestaltungszyklus mit Anforderungsanalyse, Design und Evaluation. Zudem stellt sich die Frage, wie die Herausforderungen in den Bereichen Kontrollverlust und Unsicherheit auf Benutzerseite methodisch berücksichtigt werden können.

Social resource sharing systems are central elements of the Web 2.0 and use the same kind of lightweight knowledge representation, called folksonomy. Their large user communities and ever-growing networks of user-generated content have made them an attractive object of investigation for researchers from different disciplines like Social Network Analysis, Data Mining, Information Retrieval or Knowledge Discovery. In this paper, we summarize and extend our work on different aspects of this branch of Web 2.0 research, demonstrated and evaluated within our own social bookmark and publication sharing system BibSonomy, which is currently among the three most popular systems of its kind. We structure this presentation along the different interaction phases of a user with our system, coupling the relevant research questions of each phase with the corresponding implementation issues. This approach reveals in a systematic fashion important aspects and results of the broad bandwidth of folksonomy research like capturing of emergent semantics, spam detection, ranking algorithms, analogies to search engine log data, personalized tag recommendations and information extraction techniques. We conclude that when integrating a real-life application like BibSonomy into research, certain constraints have to be considered; but in general, the tight interplay between our scientific work and the running system has made BibSonomy a valuable platform for demonstrating and evaluating Web 2.0 research.
Query Logs as Folksonomies. Benz, Dominik; Hotho, Andreas; Jäschke, Robert; Krause, Beate; Stumme, Gerd. In Datenbank-Spektrum, 10(1), pp. 15–24. 2010.

Query logs provide a valuable resource for preference information in search. A user clicking on a specific resource after submitting a query indicates that the resource has some relevance with respect to the query. To leverage the information ofquery logs, one can relate submitted queries from specific users to their clicked resources and build a tripartite graph ofusers, resources and queries. This graph resembles the folksonomy structure of social bookmarking systems, where users addtags to resources. In this article, we summarize our work on building folksonomies from query log files. The focus is on threecomparative studies of the system’s content, structure and semantics. Our results show that query logs incorporate typicalfolksonomy properties and that approaches to leverage the inherent semantics of folksonomies can be applied to query logsas well.

Context-aware computing refers to a general class of computing systems that can sense their physical environment and adapt their behavior accordingly. In order to behave properly, such systems rely on valid and reliable context information. Therefore concepts for validating the correctness of context data are required. In our previous research we have introduced the Context Pattern Method (CPM) that calculates the probability of correctness measure, which quantifies the belief that the context information is correct and reliable. In this paper we use the CPM method and two well known statistical classification methods, Linear Discriminant Analysis (LDA) and the Support Vector Machines (SVM), to validate the context information and compare their performances under different conditions.
User Involvement in Requirements Elicitation on the Example of a System with Autonomous Mobile Robots for Inspection of Gas Pipes. Cramar, L.; Hegenberg, J.; Schmidt, L. Berlin, 2010.
- [ Abstract ]
- [ BibSonomy-Post ]
High technical know-how is needed to automate a manually conducted task. During the system design process the main focus is usually put on the engineering part, but the involvement of users, their knowledge, workflow, and mental models are rarely considered. The resulting technical system is fully functional, but insufficiently accepted by the users. As an example of user involvement in requirements analysis, we present a conceptual design of a system with autonomous mobile robots for inspection of gas pipes in large technical plants. In addition to user observation and task analysis, a questionnaire for elicitation of user requirements has been developed. The questionnaire inquires the operators’ knowledge and flow of work during the inspection planning and conducting, the impact of environmental parameters, subjective difficulties, and anticipation of advantages of using the system. The resulting implications for the development and design of human-computer-interface as well as human-robot-interaction are introduced.

Based on the wireless world research forum (WWRF) vision of seven trillion wireless devices serving seven billion people by 2020, we identified several key user requirements and a scenario to motivate research on many different technical areas. If addressed successfully by the research community and the industry, innovation in new air interfaces (for high bit rate and capacity and low latency); network architectures (like mobile cloud, mesh networks, or cognitive systems); solutions to privacy, security, and trust; and devices that do not need to be recharged for long periods would unleash an era of the wireless world where: each and every person will be empowered by wireless services. Wireless device(s) will become our interface to the digital world. We will live an ambient life style, such that: 1) our mobile device will become the key enabler to interact with smart environments and users; and 2) our mobile device will be a trusted personal assistant that will be indispensible. We will enjoy and benefit from an untethered-but-connected user experience and ubiquitous service delivery with a consistent user experience.

Kooperative Verschlagwortungs- bzw. Social-Bookmarking-Systeme wie Delicious, Mister Wong oder auch unser eigenes System BibSonomy erfreuen sich immer größerer Beliebtheit und bilden einen zentralen Bestandteil des heutigen Web 2.0. In solchen Systemen erstellen Nutzer leichtgewichtige Begriffssysteme, sogenannte Folksonomies, die die Nutzerdaten strukturieren. Die einfache Bedienbarkeit, die Allgegenwärtigkeit, die ständige Verfügbarkeit, aber auch die Möglichkeit, Gleichgesinnte spontan in solchen Systemen zu entdecken oder sie schlicht als Informationsquelle zu nutzen, sind Gründe für ihren gegenwärtigen Erfolg. Der Artikel führt den Begriff Social Bookmarking ein und diskutiert zentrale Elemente (wie Browsing und Suche) am Beispiel von BibSonomy anhand typischer Arbeitsabläufe eines Wissenschaftlers. Wir beschreiben die Architektur von BibSonomy sowie Wege der Integration und Vernetzung von BibSonomy mit Content-Management-Systemen und Webauftritten. Der Artikel schließt mit Querbezügen zu aktuellen Forschungsfragen im Bereich Social Bookmarking.

Driven by the emergence of mobile and ubiquitous computing there is a growing demand for context-aware applications that can dynamically adapt to their runtime environment. Middleware support for providing such adaptation to mobile applications has been an attractive research and development issue for several years now. However, one of the major challenges to support adaptation is that they can not be always foreseen during the design time. In a ubiquitous computing environment, a number of mobile devices running adaptive applications supported by the instances of the same middleware may come and go in a particular adaptation domain in an unanticipated manner. Moreover, third party services may also appear and disappear with respect to that particular adaptation domain. In componentbased application architectures, with the enhancement of integrating services, mobile applications may benefit from using the components that are provided by other users as well as using third party services. At runtime the application is composed of the components and the services available within the adaptation domain. This thesis provides an approach, including theoretical background, an adaptation middleware, an MDA-based application development methodology and a tool chain, in order to solve such unanticipated adaptation problems.

Stop Thinking, start Tagging - Tag Semantics emerge from Collaborative Verbosity. Körner, Christian; Benz, Dominik; Strohmaier, Markus; Hotho, Andreas; Stumme, Gerd. In Proceedings of the 19th International World Wide Web Conference (WWW 2010). ACM, Raleigh, NC, USA, 2010.

Recent research provides evidence for the presence of emergent semantics in collaborative tagging systems. While several methods have been proposed, little is known about the factors that influence the evolution of semantic structures in these systems. A natural hypothesis is that the quality of the emergent semantics depends on the pragmatics of tagging: Users with certain usage patterns might contribute more to the resulting semantics than others. In this work, we propose several measures which enable a pragmatic differentiation of taggers by their degree of contribution to emerging semantic structures. We distinguish between categorizers, who typically use a small set of tags as a replacement for hierarchical classification schemes, and describers, who are annotating resources with a wealth of freely associated, descriptive keywords. To study our hypothesis, we apply semantic similarity measures to 64 different partitions of a real-world and large-scale folksonomy containing different ratios of categorizers and describers. Our results not only show that ‘verbose’ taggers are most useful for the emergence of tag semantics, but also that a subset containing only 40% of the most ‘verbose’ taggers can produce results that match and even outperform the semantic precision obtained from the whole dataset. Moreover, the results suggest that there exists a causal link between the pragmatics of tagging and resulting emergent semantics. This work is relevant for designers and analysts of tagging systems interested (i) in fostering the semantic development of their platforms, (ii) in identifying users introducing “semantic noise”, and (iii) in learning ontologies.

Soziale Tagging-Systeme gehören zu den in den vergangenen Jahren entstandenen Web2.0-Systemen. Sie ermöglichen es Anwendern, beliebige Informationen in das Internet einzustellen und untereinander auszutauschen. Je nach Anbieter verlinken Nutzer Videos, Fotos oder Webseiten und beschreiben die eingestellten Medien mit entsprechenden Schlagwörtern (Tags). Die damit einhergehende freiwillige Preisgabe oftmals persönlicher Informationen wirft Fragen im Bereich der informationellen Selbstbestimmung auf. Dieses Grundrecht gewährleistet dem Einzelnen, grundsätzlich selbst über die Preisgabe und Verwendung seiner persönlichen Daten zu bestimmen. Für viele Funktionalitäten, wie beispielsweise Empfehlungsdienste oder die Bereitstellung einer API, ist eine solche Kontrolle allerdings schwierig zu gestalten. Oftmals existieren keine Richtlinien, inwieweit Dienstanbieter und weitere Dritte diese öffentlichen Daten (und weitere Daten, die bei der Nutzung des Systems anfallen) nutzen dürfen. Dieser Artikel diskutiert anhand eines konkreten Systems typische, für den Datenschutz relevante Funktionalitäten und gibt Handlungsanweisungen für eine datenschutzkonforme technische Gestaltung.

The area of activity recognition is essential for context-aware systems. Previous and current investigations demonstrate that the accelerometer is suitable for accurate movement and activity recognition. Since smartphones are used by people in their daily lives, they can be seen as an attractive sensor device for the purpose of activity recognition. In our work, experiments have been carried out to investigate the suitability of the built-in accelerometer by comparing the influences of classification algorithms, features and the combination of sampling rates and window sizes for features extraction have on the classification accuracy. Obtained results indicate that smartphones similar to the test device provide good accuracy in recognizing common movements.

Community mining is a prominent approach for identifying (user) communities in social and ubiquitous contexts. While there are a variety of methods for community mining and detection, the effective evaluation and validation of the mined communities is usually non-trivial. Often there is no evaluation data at hand in order to validate the discovered groups. This paper proposes evidence networks using implicit information for the evaluation of communities. The presented evaluation approach is based on the idea of reconstructing existing social structures for the assessment and evaluation of a given clustering. We analyze and compare the presented evidence networks using user data from the real-world social bookmarking application BibSonomy. The results indicate that the evidence networks reflect the relative rating of the explicit ones very well.

Je komplizierter technische Geräte werden, desto mehr Ärger können sie bei ihren Benutzern verursachen. Es gibt wohl kaum jemanden, der nicht schon einmal gern seinen PC aus dem Fenster geworfen oder eigenhändig zertrümmert hätte. Wenige, die nicht bei der Installation eines neuen DVD-Rekorders kurz vor der Kapitulation standen. Hilfe kommt nun verstärkt aus der psychologischen Forschung, die sich intensiv damit beschäftigt, wie Apparate anwenderfreundlich und klug gestaltet werden können.

Until now informational self-determination has not been examined in relation to context prediction. The right of users to decide whether or not and how they want their personal data to be used is not ensured. This paper analyses the problem by introducing the state of the art and application fields of context prediction with focus on the users' personal data. Subsequently, informational self-determination and the problems that arise if techniques of context prediction compete with informational self determination will be presented. Finally, possible solutions for overcoming these problems will be outlined.

Business processes and their implementation as Web Service Compositions are not only dependent on Web Services and partners all over the Internet, but also on their failsafe execution. Service providers have to obligate their services to perform according to negotiated Quality of Service (QoS) parameters. For example, response time and throughput are important parameters to achieve fast and efficient services. Overloaded or failing services may compromise the reliability and execution of whole enterprise processes. In this paper we introduce a flexible monitoring approach for the measurement of QoS in BPEL (Business Process Execution Language) processes. We propose a generic algorithm for QoS aggregation in BPEL processes. The novel generic aggregation algorithm applies customized aggregation functions for QoS dimensions. Furthermore, we present a BPEL monitoring system which supports ad-hoc sensor deployment and efficient runtime and offline data aggregation not only for whole process descriptions but also sections inside service processes.

Every year still thousands of people are injured or killed in accidents with cars, trucks and busses. Many of these people are pedestrians or cyclists. Several research groups work on solutions to avoid accidents between cars and pedestrians with the help of different technologies. In this paper we present an innovative approach for a collision avoidance system which should be able to tackle these accidents. To understand the potential of this approach, we will present a physical analysis of the system time available between detection, warning and reaction. We also discuss different architectures of our approach utilizing ad-hoc and/or cellular technologies. Additionally, we present experimental results of connection establishment and ping response times of these wireless technologies.

In our living environments today, computer networks, computing devices, sensors and many other entities produce a large amount of data to be processed. This data comprise, for example, digital media content, news, computational resources like services, and much more. To be able to exploit this data, a (human or computer) user may utilize digital assistants. In this paper, we present such an assistant for deploying services and obtaining content data. We concentrate especially on how this assistant is able to adapt to changing situations, both, user-driven and in a self-adaptive manner. An experimental evaluation, based on real world digital video providers, demonstrates prerequisites, results, and potential of the various ways of adaptation within the presented approach.

Social bookmarking systems and their emergent information structures, known as folksonomies, are increasingly important data sources for Semantic Web applications. A key question for harvesting semantics from these systems is how to extend and adapt traditional notions of similarity to folksonomies, and which measures are best suited for applications such as navigation support, semantic search, and ontology learning. Here we build an evaluation framework to compare various general folksonomy-based similarity measures derived from established information-theoretic, statistical, and practical measures. Our framework deals generally and symmetrically with users, tags, and resources. For evaluation purposes we focus on similarity among tags and resources, considering different ways to aggregate annotations across users. After comparing how tag similarity measures predict user-created tag relations, we provide an external grounding by user-validated semantic proxies based on WordNet and the Open Directory. We also investigate the issue of scalability. We ?nd that mutual information with distributional micro-aggregation across users yields the highest accuracy, but is not scalable; per-user projection with collaborative aggregation provides the best scalable approach via incremental computations. The results are consistent across resource and tag similarity.

Der Artikel beschreibt die benutzerzentrierte Entwicklung eines Navigationssystems für Fußgänger, das auf einem mobilen Endgerät mit Touchscreen umgesetzt wurde. Es werden spezielle Anforderungen von Fußgängern an Navigationshilfen erläutert und Unterschiede zu Autonavigationssystemen diskutiert. Beispielsweise ist es viel schwieriger, eine Orientierung für Fußgänger zu ermöglichen, da sie sich weniger auf einem festgelegten Straßennetz bewegen und sich eher an markanten örtlichen Gegebenheiten, wie Kreuzungspunkten und Landmarken, orientieren. Auch der Nutzungskontext einer solchen Navigationshilfe differiert, weil es, im Gegensatz zur Fortbewegung mit dem Auto, weniger darauf ankommt, effizient von Punkt A nach B zu kommen, als die Wegfindung mit parallelen freizeitbezogenen Tätigkeiten, wie Bummeln oder Schlendern, zu verbinden. Das entwickelte Konzept ermöglicht die Nutzung verschiedener vordefinierter Kartenansichten für Orientierungs- und Wegefindungsbedürfnisse. Das sindeine Übersichtskarte, eine Restwegkarte und eine Detailkarte für komplexe Raumsituationen. Die unterschiedlichen Nutzungssituationen werden durch verschiedene Modi, z.B. einen Wegfindungsmodus und einen Freizeitmodus, bei dem eher die Orientierung anstelle der Wegfindung im Vordergrund steht, unterstützt. Die Vorgehensweise bei der Entwicklung, zu der z.B. auch ein Wizard-of-Oz Feldtest gehörte, wird kurz erläutert und wichtige Erkenntnisse vorgestellt. Es zeigte sich u.a. insgesamt eine hohe Akzeptanz gegenüber dem entwickelten Prototyp. Zudem wurden die Grundkonzepte bestätigt. Änderungsbedarf ergab sich in Aspekten des Interaktions- und Informationsdesigns. Es mussten z.B. alle automatischen Zooms zwischen Kartenansichten durch einen vom Benutzer initiierten Aufruf ersetzt werden. Außerdem werden im vorliegenden Beitrag ergänzend aktuelle Entwicklungen im Bereich Handynavigation und Fußgängernavigationssysteme aufgegriffen und vergleichend diskutiert.

Die Bedeutung des Dienstgüte-Managements (SLM) im Bereich von Unternehmensanwendungen steigt mit der zunehmenden Kritikalität von IT-gestützten Prozessen für den Erfolg einzelner Unternehmen. Traditionell werden zur Implementierung eines wirksamen SLMs Monitoringprozesse in hierarchischen Managementumgebungen etabliert, die einen Administrator bei der notwendigen Rekonfiguration von Systemen unterstützen. Auf aktuelle, hochdynamische Softwarearchitekturen sind diese hierarchischen Ansätze jedoch nur sehr eingeschränkt anwendbar. Ein Beispiel dafür sind dienstorientierte Architekturen (SOA), bei denen die Geschäftsfunktionalität durch das Zusammenspiel einzelner, voneinander unabhängiger Dienste auf Basis deskriptiver Workflow-Beschreibungen modelliert wird. Dadurch ergibt sich eine hohe Laufzeitdynamik der gesamten Architektur. Für das SLM ist insbesondere die dezentrale Struktur einer SOA mit unterschiedlichen administrativen Zuständigkeiten für einzelne Teilsysteme problematisch, da regelnde Eingriffe zum einen durch die Kapselung der Implementierung einzelner Dienste und zum anderen durch das Fehlen einer zentralen Kontrollinstanz nur sehr eingeschränkt möglich sind. Die vorliegende Arbeit definiert die Architektur eines SLM-Systems für SOA-Umgebungen, in dem autonome Management-Komponenten kooperieren, um übergeordnete Dienstgüteziele zu erfüllen: Mithilfe von Selbst-Management-Technologien wird zunächst eine Automatisierung des Dienstgüte-Managements auf Ebene einzelner Dienste erreicht. Die autonomen Management-Komponenten dieser Dienste können dann mithilfe von Selbstorganisationsmechanismen übergreifende Ziele zur Optimierung von Dienstgüteverhalten und Ressourcennutzung verfolgen. Für das SLM auf Ebene von SOA Workflows müssen temporär dienstübergreifende Kooperationen zur Erfüllung von Dienstgüteanforderungen etabliert werden, die sich damit auch über mehrere administrative Domänen erstrecken können. Eine solche zeitlich begrenzte Kooperation autonomer Teilsysteme kann sinnvoll nur dezentral erfolgen, da die jeweiligen Kooperationspartner im Vorfeld nicht bekannt sind und – je nach Lebensdauer einzelner Workflows – zur Laufzeit beteiligte Komponenten ausgetauscht werden können. In der Arbeit wird ein Verfahren zur Koordination autonomer Management-Komponenten mit dem Ziel der Optimierung von Antwortzeiten auf Workflow-Ebene entwickelt: Management-Komponenten können durch Übertragung von Antwortzeitanteilen untereinander ihre individuellen Ziele straffen oder lockern, ohne dass das Gesamtantwortzeitziel dadurch verändert wird. Die Übertragung von Antwortzeitanteilen wird mithilfe eines Auktionsverfahrens realisiert. Technische Grundlage der Kooperation bildet ein Gruppenkommunikationsmechanismus. Weiterhin werden in Bezug auf die Nutzung geteilter, virtualisierter Ressourcen konkurrierende Dienste entsprechend geschäftlicher Ziele priorisiert. Im Rahmen der praktischen Umsetzung wird die Realisierung zentraler Architekturelemente und der entwickelten Verfahren zur Selbstorganisation beispielhaft für das SLM konkreter Komponenten vorgestellt. Zur Untersuchung der Management-Kooperation in größeren Szenarien wird ein hybrider Simulationsansatz verwendet. Im Rahmen der Evaluation werden Untersuchungen zur Skalierbarkeit des Ansatzes durchgeführt. Schwerpunkt ist hierbei die Betrachtung eines Systems aus kooperierenden Management-Komponenten, insbesondere im Hinblick auf den Kommunikationsaufwand. Die Evaluation zeigt, dass ein dienstübergreifendes, autonomes Performance-Management in SOA-Umgebungen möglich ist. Die Ergebnisse legen nahe, dass der entwickelte Ansatz auch in großen Umgebungen erfolgreich angewendet werden kann.

Benutzerzentrierte Augmented-Reality-Systemgestaltung. Schmidt, L. Kassel, 2009.
- [ Abstract ]
- [ BibSonomy-Post ]
Augmented Reality (AR) ist eine in der praktischen Anwendung immer noch wenig verbreitete interaktive Technologie, die die reale Umwelt so mit computergenerierten Informationen bedarfsgerecht und kontextbezogen ergänzen oder bereichern (augmentieren) kann, dass für den Benutzer der Eindruck einer Verschmelzung dieser Informationen mit der wahrgenommenen Realität entsteht. Neben einem Überblick zu den damit zusammenhängenden Gestaltungsbereichen für die Mensch-Maschine-Interaktion wird ein an ISO 13407 angelehntes Vorgehen vorgestellt, das eine aufgaben- und benutzergerechte Systemgestaltung gewährleisten soll. Dieses systematische Vorgehen wird im Vortrag anhand von Anwendungsbeispielen konkretisiert. Beispielsweise wurden in der Analysephase die Anforderungen an AR-Anwendungen partizipativ und szenarienbasiert in verschiedenen Fokusgruppen erhoben, bevor sie zu Use Cases zusammengefasst wurden. Mit dieser benutzerzentrierten Perspektive werden außerdem grundlagenergonomische Fragen der Displays und Informationsdarstellung, das Usability Engineering der Benutzungsschnittstellen und systemergonomische Fragestellungen der AR-Technologienutzung in unterschiedlichen Anwendungsfeldern und Arbeitskontexten aufgegriffen.

Supervisory control of complex systems or processes by a human operator can be understood as a superordinated control loop of the technical system. In this procedure there are three steps: (1) the operator monitors the state of a process or system, (2) he analyses and assesses it in comparison with a desired state, and finally (3), a correction by a specific operation is planned and carried out, if necessary. In the context of military aerial surveillance, the essential identification and classification tasks of aircrafts are based on various sensors and data exchange with other military units. Numerous additional conditions (e.g. the political situation) have to be considered. To assist operators in aerial surveillance tasks as well as in time-critical situations and at a computer workstation with a high informational workload, the design of ergonomic human-computer interaction is a crucial factor. A model-based design of human-computer interaction for aerial surveillance tasks at military workplaces is described in this contribution. First, interactions are generally characterized according to an extended semiotic model containing four levels of interaction (pragmatic, semantic, syntactic, and physical). In the second step, the model is used for deriving and describing design consequences. Finally, as an example, it is illustrated how to design a user interface for aerial surveillance tasks according to the model.

Für ein Verstehen des komplexen Themas "Gesundheit" ist zunächst eine Analyse der Rahmenbedingungen und Einflussgrößen erforderlich. Ergonomische Gestaltungsfelder müssen erkannt und gesundheitsförderliche Prinzipien verstanden werden, bevor Methoden zur gesundheitsförderlichen Arbeitsgestaltung angewendet und im Unternehmen organisatorisch verankert werden können. Nicht zuletzt hat Gesundheit einen, wenn auch häufig nicht entsprechend akzeptierten, hohen Stellenwert für die Wirtschaftlichkeit des Unternehmens. Gesundheitsförderung wird so zum "wertschöpfenden" Prozess und zur Querschnittsaufgabe für alle betrieblichen Akteure. Wesentliche Rahmenbedingungen und Entwicklungstendenzen sind: (1) Rechtliche Rahmenbedingungen des Arbeits- und Gesundheitsschutzes und Regelungen der Unfallversicherungsträger mit rechtlich bindendem Charakter, (2) personenbezogene Entwicklungstendenzen wie höhere Qualifikation, höherer Stellenwert persönlicher Gesundheit, steigendes mittleres Alter der Erwerbstätigen u.a., (3) Entwicklung von Krankheitsarten und des Umfangs krankheitsbedingter Ausfälle, (4) Organisatorische Entwicklungen wie Dezentralisierung von Verantwortung, Flexibilisierung von Arbeitszeiten, Veränderungen von Aufgabeninhalten und -strukturen etc. sowie (5) Technische Entwicklungen, wie z.B. die zunehmende Anzahl von Bildschirmarbeitsplätzen oder die Integration von Automatisierungstechnologie.

Die fortschreitende Technisierung der Umwelt bewirkt eine zunehmende Überschneidung der realen mit der digitalen Welt. Daraus ergeben sich im mobilen sozialen Nutzungskontext interessante Entwicklungspotentiale für neue Technologien und neuartige Kommunikations- und Interaktionsformen. Die bisher praktizierten Interaktionsformen und -regeln der zwei Welten treffen aufeinander, ergänzen und erweitern sich. Beispielsweise werden die Möglichkeiten zur Bildung und Pflege sozialer Beziehungen und Netzwerke zusammengeführt. In diesem Beitrag werden beispielhaft mögliche neue Interaktionsformen in der Grammatik von Design Patterns (vgl. Lukosch, 2007) dargestellt. Daneben wird das ihnen zugrunde liegende Rahmenkonzept erläutert. Dessen Bestandteile sind u.a. die Elemente Lokalität, Zeit, soziales Objekt und Embodied Interaction als Verbindungsglied zwischen realer und digitaler Welt.

Evolving Distributed Algorithms with Genetic Programming. Weise, Thomas. University of Kassel, Fachbereich 16: Elektrotechnik/Informatik, Distributed Systems Group, Fachbereich 16: Elektrotechnik/Informatik, University of Kassel, Germany, 2009.

Distributed systems are one of the most vital components of the economy. The most prominent example is probably the internet, a constituent element of our knowledge society. During the recent years, the number of novel network types has steadily increased. Amongst others, sensor networks, distributed systems composed of tiny computational devices with scarce resources, have emerged. The further development and heterogeneous connection of such systems imposes new requirements on the software development process. Mobile and wireless networks, for instance, have to organize themselves autonomously and must be able to react to changes in the environment and to failing nodes alike. Researching new approaches for the design of distributed algorithms may lead to methods with which these requirements can be met efficiently. In this thesis, one such method is developed, tested, and discussed in respect of its practical utility. Our new design approach for distributed algorithms is based on Genetic Programming, a member of the family of evolutionary algorithms. Evolutionary algorithms are metaheuristic optimization methods which copy principles from natural evolution. They use a population of solution candidates which they try to refine step by step in order to attain optimal values for predefined objective functions. The synthesis of an algorithm with our approach starts with an analysis step in which the wanted global behavior of the distributed system is specified. From this specification, objective functions are derived which steer a Genetic Programming process where the solution candidates are distributed programs. The objective functions rate how close these programs approximate the goal behavior in multiple randomized network simulations. The evolutionary process step by step selects the most promising solution candidates and modifies and combines them with mutation and crossover operators. This way, a description of the global behavior of a distributed system is translated automatically to programs which, if executed locally on the nodes of the system, exhibit this behavior. In our work, we test six different ways for representing distributed programs, comprising adaptations and extensions of well-known Genetic Programming methods (SGP, eSGP, and LGP), one bio-inspired approach (Fraglets), and two new program representations called Rule-based Genetic Programming (RBGP, eRBGP) designed by us. We breed programs in these representations for three well-known example problems in distributed systems: election algorithms, the distributed mutual exclusion at a critical section, and the distributed computation of the greatest common divisor of a set of numbers. Synthesizing distributed programs the evolutionary way does not necessarily lead to the envisaged results. In a detailed analysis, we discuss the problematic features which make this form of Genetic Programming particularly hard. The two Rule-based Genetic Programming approaches have been developed especially in order to mitigate these difficulties. In our experiments, at least one of them (eRBGP) turned out to be a very efficient approach and in most cases, was superior to the other representations.

Several learning tasks comprise hierarchies. Comparison with a "goldstandard" is often performed to evaluate the quality of a learned hierarchy. We assembled various similarity metrics that have been proposed in different disciplines and compared them in a unified interdisciplinary framework for hierarchical evaluation which is based on the distinction of three fundamental dimensions. Identifying deficiencies for measuring structural similarity, we suggest three new measures for this purpose, either extending existing ones or based on new ideas. Experiments with an artificial dataset were performed to compare the different measures. As shown by our results, the measures vary greatly in their properties.

The objective of our group was to exploit state-of-the-art Information Retrieval methods for finding associations and dependencies between tags, capturing and representing differences in tagging behavior and vocabulary of various folksonomies, with the overall aim to better understand the semantics of tags and the tagging process. Therefore we analyze the semantic content of tags in the Flickr and Delicious folksonomies. We find that: tag context similarity leads to meaningful results in Flickr, despite its narrow folksonomy character; the comparison of tags across Flickr and Delicious shows little semantic overlap, being tags in Flickr associated more to visual aspects rather than technological as it seems to be in Delicious; there are regions in the tag-tag space, provided with the cosine similarity metric, that are characterized by high density; the order of tags inside a post has a semantic relevance.

Collaborative tagging systems have nowadays become important data sources for populating semantic web applications. For taskslike synonym detection and discovery of concept hierarchies, many researchers introduced measures of tag similarity. Eventhough most of these measures appear very natural, their design often seems to be rather ad hoc, and the underlying assumptionson the notion of similarity are not made explicit. A more systematic characterization and validation of tag similarity interms of formal representations of knowledge is still lacking. Here we address this issue and analyze several measures oftag similarity: Each measure is computed on data from the social bookmarking system del.icio.us and a semantic grounding isprovided by mapping pairs of similar tags in the folksonomy to pairs of synsets in Wordnet, where we use validated measuresof semantic distance to characterize the semantic relation between the mapped tags. This exposes important features of theinvestigated similarity measures and indicates which ones are better suited in the context of a given semantic application.

The current computing and communication services are driven by various technologies. The creation of such services is however not an easy task. The different platforms lack openness that simplifies interoperability. Service development is still mainly technical oriented, where service creation tools are meant for serving and assisting the professional developers. Service creation is not seen as a task for end users right now. In this paper we will discuss how end users could be enabled to create new services, shown on the example within a mobile context-aware service platform. This is achieved by introducing the concept of the technology agnostic approach into the process. We present the conceptual architecture and explain the idea of end-user driven service creation that can provide a solution. Several tools were designed and implemented to prove that the concepts work. With the help of semantic service description, the end users can express their service wishes and create services using a graphical interface technology agnostically. The idea was implemented in two European projects and we have identified the next steps to improve the prototypes as well as the idea. Based on several tools and an underlying platform the ideas have been tested in a development environment for mobile context-aware services. Here end-users are able to design their own services or combine existing services, which can be shared and used by other users later on.

In social bookmarking systems users describe bookmarksby keywords called tags. The structure behindthese social systems, called folksonomies, can beviewed as a tripartite hypergraph of user, tag and resourcenodes. This underlying network shows specificstructural properties that explain its growth and the possibilityof serendipitous exploration.Search engines filter the vast information of the web.Queries describe a user’s information need. In responseto the displayed results of the search engine, users clickon the links of the result page as they expect the answerto be of relevance. The clickdata can be represented as afolksonomy in which queries are descriptions of clickedURLs. This poster analyzes the topological characteristicsof the resulting tripartite hypergraph of queries,users and bookmarks of two query logs and compares ittwo a snapshot of the folksonomy del.icio.us.

Collaborative tagging systems allow users to assign keywords - so called "tags" - to resources. Tags are used for navigation, finding resources and serendipitous browsing and thus provide an immediate benefit for users. These systems usually include tag recommendation mechanisms easing the process of finding good tags for a resource, but also consolidating the tag vocabulary across users. In practice, however, only very basic recommendation strategies are applied. In this paper we evaluate and compare several recommendation algorithms on large-scale real life datasets: an adaptation of user-based collaborative filtering, a graph-based recommender built on top of the FolkRank algorithm, and simple methods based on counting tag occurences. We show that both FolkRank and Collaborative Filtering provide better results than non-personalized baseline methods. Moreover, since methods based on counting tag occurrences are computationally cheap, and thus usually preferable for real time scenarios, we discuss simple approaches for improving the performance of such methods. We show, how a simple recommender based on counting tags from users and resources can perform almost as good as the best recommender.

Pervasive computing includes the vision of small but intelligent devices around us. While the hardware of such devices is available in the market for years,they are still not intelligent in our every day life. For the success of the idea of pervasive computing a unified programming model is needed. Without a standard way of composing intelligent applications for pervasive computing, especially context aware applications to minimize user input, and without standard communication protocols it will take a longtime till before we will see those applications in the market. To establish such standards we first need to be clear of the requirements and how to deal with those requirements in the best way. In this paper we present three important requirements. Moreover we present anew framework DAGR (Directed acyclic graph based context reasoning) to address these requirements.

Social bookmarking systems constitute an established part of the Web 2.0. In such systems users describe bookmarks by keywords called tags. The structure behind these social systems, called folksonomies, can be viewed as a tripartite hypergraph of user, tag and resource nodes. This underlying network shows specific structural properties that explain its growth and the possibility of serendipitous exploration. Today’s search engines represent the gateway to retrieve information from the World Wide Web. Short queries typically consisting of two to three words describe a user’s information need. In response to the displayed results of the search engine, users click on the links of the result page as they expect the answer to be of relevance. This clickdata can be represented as a folksonomy in which queries are descriptions of clicked URLs. The resulting network structure, which we will term logsonomy is very similar to the one of folksonomies. In order to find out about its properties, we analyze the topological characteristics of the tripartite hypergraph of queries, users and bookmarks on a large snapshot of del.icio.us and on query logs of two large search engines. All of the three datasets show small world properties. The tagging behavior of users, which is explained by preferential attachment of the tags in social bookmark systems, is reflected in the distribution of single query words in search engines. We can conclude that the clicking behaviour of search engine users based on the displayed search results and the tagging behaviour of social bookmarking users is driven by similar dynamics.

An Approach to Autonomic Deployment Decision Making. Kusber, Rico; Haseloff, Sandra; David, Klaus. In Proceedings of the Third International Workshop on Self-Organizing Systems, pp. 121–132. Springer International Publishing, Berlin, Heidelberg, Germany, 2008.

Adding autonomicity to computing systems seems to be a promising way to deal with the problem of increasing system complexity. One step along the way to self-managing computing systems – especially with regard to distributed, modularized, service based environments – is to solve the problem of how to autonomically decide in a most useful and resource efficient way which alternative to choose in order to deploy a service. Deploying a service means, to either copy or move it from a source to a destination device or to use it remotely. In this paper we motivate the domain of autonomic service deployment and present an approach for deployment decision making (DDM). We explain all steps of the deployment decision making process and assemble them into an algorithm accordingly. Furthermore, we define all necessary components of DDM and enumerate a set of research questions which we address in order to fully explore the concerned domain. An experiment illustrates the potential of the presented approach.

The current computing and communication services are driven by various technologies. The creation of such services is however not an easy task. The different platforms lack of openness that simplifies interoperability. Service developments are still mainly technical oriented, where service creation tools are meant for serving and assisting the professional developers. Service creation is not seen as a task for the end users. In our projects we wish to enable service creation for the end users. This is achieved by introducing the concept of the technology agnostic approach into the process. We present the conceptual architecture and explain the idea that can provide a solution. Several tools were designed and implemented to prove that the concepts work. With the help of semantic service description, the end users can express their service wishes and create services using a graphical interface technology agnostically. The service platform will search for the desired service functionalities and execute them. The idea was implemented in two European projects and we have identified the next steps to improve the prototypes as well as the idea.

The paper describes two experiments for investigating the influence of different levels of camera displacement on hand-eye coordination while using a video see-through head-mounted display. During the first experiment 15 camera positions with five levels of height displacement and three levels of depth displacement were compared in four different tasks. Using a two-way ANOVA the comparison of the calculated performance characteristic values showed significant influence of height displacement on hand-eye coordination. In conclusion cameras should be placed above or below eye level, but by no more than 35 mm, in order to preserve hand-eye coordination. In the second experiment, a mirror system was used to check hand-eye coordination in an exemplary medical task allowing the cameras to be placed virtually at eye level. A significant decrease in accuracy was found while using the head-mounted display compared to direct view. Finally, the mirror system was compared to the 15 camera positions using the data from the same tasks. Significant differences in performance were found between the mirror system and eye level position as well as the position slightly below eye level. The results of the experiment provide design recommendations for developers and users of video see-through systems.

In diesem Beitrag wird ein Entscheidungsleiter-Modell für die menschliche Informationsverarbeitung vorgestellt und exemplarisch für die Gestaltung von Benutzungsschnittstellen verwendet. Das hierarchisch geordnete Modell bildet Wissenszustände und Informationsverarbeitungsschritte bei der Situationsanalyse und Handlungsplanung ab und wird als Grundlage für eine kognitiv-kompatible Systemgestaltung genutzt. Durch die Unterteilung des gesamten Verarbeitungsprozesses in verschiedene kognitive Teilaufgaben lassen sich die jeweils dazu benötigten Informationen identifizieren und formulieren. Jede der im Modell repräsentierten Analyseaktivitäten verlangt nach einer speziellen Art der Darstellung der zugrundeliegenden Informationen, damit sie optimal in den erforderlichen Entscheidungsschritt eingebunden werden können. Im Einzelnen werden dazu Aspekte der Aktivierung, der Beobachtung und Identifizierung von kritischen Zuständen, der regelbasierten Ableitung von Handlungsbedarf, der Bildung von Zustandsgrößen und der wissensbasierten Analyse und Handlungsplanung aufgegriffen und anhand eines Anwendungsbeispiels konkretisiert. Dazu wurde exemplarisch eine Mensch-Maschine-Schnittstelle konzipiert und prototypisch in einer Experimental- und Testumgebung realisiert, mit deren Hilfe Prozesse der Luftraumüberwachung und Lagebewertung durch einen Operateur auf verschiedenen kognitiven Ebenen unterstützt werden sollen.

Dieser Beitrag beschreibt die modellbasierte Gestaltung der Mensch-Computer-Interaktion an militärischen Arbeitsplätzen zur Luftlagebewertung. Die Interaktion wird zunächst allgemein anhand eines erweiterten Semiotischen Modells auf vier Ebenen (pragmatisch, semantisch, syntaktisch und physikalisch) charakterisiert. Daraus werden die entsprechenden Gestaltungsbereiche abgeleitet und kurz beschrieben. Als exemplarische Umsetzung wird dann anhand eines Prototyps die Gestaltung einer Benutzungsschnittstelle für die Luftlagebewertung dargestellt.

Die ergonomische Gestaltung von komplexen, dynamischen Systemen, in denen Menschen und Maschinen eng zusammenarbeiten, stellt eine besondere wissenschaftliche und technische Herausforderung dar. Durch innovative Konzepte und Technologien ist es heute möglich, den Menschen sehr viel besser als noch vor wenigen Jahren zu befähigen, hochautomatisierte Systeme effektiv und effizient führen und überwachen zu können. Gestaltungsziel ist es, die überragenden Fähigkeiten des Menschen im perzeptiven, kognitiven und sensumotorischen Bereich intelligent mit teilautonomen technischen Funktionen zu verzahnen. Dabei soll der Mensch zwar von unnötigen oder gefährlichen Routineaufgaben entlastet werden, sein Situationsbewusstsein jedoch voll entfalten können. Im vorliegenden Buch stellt das FGAN Forschungsinstitut für Kommunikation, Informationsverarbeitung und Ergonomie den aktuellen Stand von Forschung und Technik dar. Der Schwerpunkt liegt in den Anwendungsbereichen Verteidigung und Sicherheit. Die 25 wissenschaftlichen Beiträge behandeln innovative Aspekte von Mensch-Maschine-Systemen wie multimodale Interaktion, 3D-Visualisierung in Virtueller Realität und Augmented Reality, adaptive Assistenzsysteme, Head-Mounted Displays, Führung unbemannter Robotersysteme, Cognitive Engineering und Ecological Interface Design oder Evaluationsmethoden für die Mensch-Maschine-Interaktion. Angesprochen werden Ingenieure, Informatiker und Technologiemanager, die verantwortlich für die Projektierung und Entwicklung von komplexen Mensch-Maschine-Systemen sind. Auch Studierende technischer Fachrichtungen können sich mit diesem Werk einen umfassenden Überblick über den Stand von Forschung und Technik verschaffen.

Service delivery platforms in telecommunication environments aim to host multiple services and to provide context-awareness and personalization features. This calls for an appropriate management of user profiles containing general user information as well as situation-dependent user preferences for the contextual personalization of these services. We present a user profile selection approach that decides on the selection of matching situation-dependent user preferences concerning the user's current situation. The presented approach takes advantage of ontology reasoning and is compared to other approaches. The comparison shows that our ontology reasoning based approach allows for more expressiveness concerning the specification of situation-dependent user preferences and hence leads to an added value for platform users.

The vision of pervasive computing and communication is likely to have a major impact on our lives. The WWRF (Wireless World Research Forum) has summarized this vision by the statement: "7 trillion wireless devices serving 7 billion people by 2017". Following this vision, the goal for new business sectors will be to provide an easy way of creating and deploying different kinds of service environments. This paper introduces the requirements on and the problem of overall architectures for service execution environments and identifies an architectural approach, the requirements and design guidelines to built service execution environments and related platforms. The concepts presented in this paper have partly been developed by the Wireless World Research Forum (WWRF) Working Group 2 (WG2) and are under ongoing discussion.

Currently, social bookmarking systems provide intuitive support for browsing locally their content. A global view is usually presented by the tag cloud of the system, but it does not allow a conceptual drill-down, e. g., along a conceptual hierarchy. In this paper, we present a clustering approach for computing such a conceptual hierarchy for a given folksonomy. The hierarchy is complemented with ranked lists of users and resources most related to each cluster. The rankings are computed using our FolkRank algorithm. We have evaluated our approach on large scale data from the del.icio.us bookmarking system.

With the successful deployment of various radio access networks, multi-radio access has become an important research topic for heterogeneous wireless networks. This paper presents several multi-standard radio resource management strategies for integrated voice and data services. The input parameters as well as the availability of overflow at call setup stage and intersystem handover during call connection stage differentiate these strategies from each other. The heterogeneous networks capacity of integrated services is investigated via simulations modelling the stochastic traffic, mobility, and technology related air interface features. Performance comparison reveals that a strategy merely maximising the capacity might not consider the performance of individual service in some cases.

Context awareness is a key feature of modern computing applications, allowing application behaviour to be adapted to context. The power and quality of context-aware applications can significantly be increased by not only considering past and present contexts for adaptation, but by also predicting and reacting to future contexts. This paper deals with fundamental challenges of context prediction. After an introduction to context prediction and a clarification of the basic terms associated with it, the paper proposes solutions concerning prediction algorithms and describes an architecture for context-aware computing, including context prediction, we have developed. The findings described in the paper are illustrated and verified by simulations using different types of context data and different prediction algorithms.

Bookmarks (or Favorites, Hotlists) are a popular strategy to relocate interesting websites on the WWW by creating a personalized local URL repository. Most current browsers offer a facility to store and manage bookmarks in a hierarchy of folders; though, with growing size, users reportedly have trouble to create and maintain a stable taxonomy. This paper presents a novel collaborative approach to ease bookmark management, especially the “classification�? of new bookmarks into a folder. We propose a methodology to realize the collaborative classification idea of considering how similar users have classified a bookmark. A combination of nearest-neighbour-classifiers is used to derive a recommendation from similar users on where to store a new bookmark. Additionally, a procedure to generate keyword recommendations is proposed to ease the annotation of new bookmarks. A prototype system called CariBo has been implemented as a plugin of the central bookmark server software SiteBar. A case study conducted with real user data supports the validity of the approach.

The popularization of mobile devices in the last years has led to the development of an increasing number of services. However the technical limitations of mobile devices call for services that require minimal interactions with the user and adapt their behaviors to the user’s expectations. Context-awareness has proven to facilitate personalization of services by enabling the adaptation of the service to the user’s situation. However, the adaptation is often carried out by using predefined rules that only apply to some contexts. In this paper, we present our approach that addresses this limitation in location-aware services by referring to the previous actions of the user. We have developed a metric to calculate the similarity between the current user’s location and the previous ones. Based on this metric, our approach provides a personalized service by determining the service behavior expected by the user in the current location. A service, the Call Profiler service, details our approach.

Social bookmark tools are rapidly emerging on the Web. In suchsystems users are setting up lightweight conceptual structurescalled folksonomies. The reason for their immediate success is thefact that no specific skills are needed for participating. In thispaper we specify a formal model for folksonomies, briefly describeour own system BibSonomy, which allows for sharing both bookmarks andpublication references, and discuss first steps towards emergent semantics.

As the number of resources on the web exceeds by far the number of documents one can track, it becomes increasingly difficult to remain up to date on ones own areas of interest. The problem becomes more severe with the increasing fraction of multimedia data, from which it is difficult to extract some conceptual description of their contents. One way to overcome this problem are social bookmark tools, which are rapidly emerging on the web. In such systems, users are setting up lightweight conceptual structures called folksonomies, and overcome thus the knowledge acquisition bottleneck. As more and more people participate in the effort, the use of a common vocabulary becomes more and more stable. We present an approach for discovering topic-specific trends within folksonomies. It is based on a differential adaptation of the PageRank algorithm to the triadic hypergraph structure of a folksonomy. The approach allows for any kind of data, as it does not rely on the internal structure of the documents. In particular, this allows to consider different data types in the same analysis step. We run experiments on a large-scale real-world snapshot of a social bookmarking system.

Recent simulation studies of heterogeneous wireless networks have shown promising system performance improvements by using multi standard radio resource management (MxRRM) with a centralised MxRRM architecture. In the present paper, the distributed MxRRM architecture is studied, including the modelling of signalling, where intersystem cell load information can only be exchanged at certain events. Consequently, the distributed MxRRM entities have to base their decisions on potentially inaccurate load information. The system performance is investigated by simulation studies, where the results of distributed MxRRM scenarios are compared to two reference cases, 1) assuming ideal system information for MxRRM and 2) separated systems without any MxRRM functionality. Furthermore, an additional dedicated mechanism to exchange the load information aiming to improve the load information accuracy is investigated.

Recently, research projects such as PADLR and SWAP have developed tools like Edutella or Bibster, which are targeted at establishing peer-to-peer knowledge management (P2PKM) systems. In such a system, it is necessary to obtain provide brief semantic descriptions of peers, so that routing algorithms or matchmaking processes can make decisions about which communities peers should belong to, or to which peers a given query should be forwarded. This paper provides a graph clustering technique on knowledge bases for that purpose. Using this clustering, we can show that our strategy requires up to 58% fewer queries than the baselines to yield full recall in a bibliographic P2PKM scenario.

We propose a channel aware resource allocation algorithm for HSDPA that receives higher overall weighted throughput than the popular proportional fair scheduler, while following the same fairness scheme. Our algorithm comhines features of the proportional fair algorithm with a recent optimisation algorithm for the randombed knapsack problem. We demonstrate the high potential of the proposed algorithm in a simulation environment.

In a ubiquitous computing environment, the state of devices may potentially change over time. Consequently, applications and services should be able to adapt to their environments. Having extensions with additional features is one possibility for adaptation. Developing software using the concepts defined for service oriented architecture promises easily adaptable software by loose coupling of services, which is a clear trend for software in 3G and B3G networks. Services are loosely coupled, in order to allow replacement and adaptation of service ensembles that suit the current situation of users. On top of this, services should optimally not be aware of extensions. Two approaches can be applied: the proxy pattern and the publish/subscribe architecture. The former allows service extension at runtime, while the latter enables communication between loosely coupled software. Implementation of both approaches results in an incompatibility problem. We introduce mutable references to solve this problem. With the proposed pattern one can implement publish/subscribe based services together with service extension at runtime via the proxy pattern.

The paradigm for ubiquitous communication aims at enabling people to contact anyone anywhere and at anytime in a convenient way. Though, this promising vision is mainly addressed from the perspective of individual users. The IST project MobiLife furthers this mobile communications paradigm by developing new applications and services. In addition to the requirements of individual users, MobiLife also considers the needs and concerns of groups of users. This paper presents an architecture that allows the management of mobile groups in heterogeneous communication environments and provides them with context-aware services. The architecture presented has been developed by and proposed within the EU IST-511607 project MobiLife.

We propose a distributed architecture for composing implicit contexts out of numerous explicit context atoms. The explicit context atoms are gathered and aggregated at runtime from a computing envi- ronment, and may not initially be intended for a composition task. The architecture supports context-aware systems to reason about implicit contexts in the presence of uncertainty.

Capturing contextual information, especially higher-level contexts enables systems to understand and predict the behaviour of a mobile user. This kind of information is mostly implicit contexts, which abstract a complex state of a situation and can only partly be captured by employing sensors. Higher-level context has the potential to make user-application interaction richer, simpler, and more intuitive. However, composing higher-level contexts from explicit, atomic contexts requires complex and painstaking reasoning procedures to resolve uncertainty due to inconsistent sensor readings and incomplete information. In this paper, we introduce a new approach that assists application developers to take higher-level contexts into account without the need to know the details of atomic contexts. To demonstrate our approach, we will introduce the Context-Aware E-Pad (CAEP) we have designed and implemented. CAEP “observes” the user making a decision and associates with it a set of atomic contexts. Likewise, correlated decisions are mapped to similar associations. By repeatedly “observing” the user making decisions, CAEP can predict user’s wishes and behaviours.

The vision of pervasive computing and communication will shape the individual life in the future. Following this vision, the goal for new business sectors will be to provide an easy way of creating and deploying different kind of service environments. This paper introduces briefly the problem of overall architectures for service execution environments and identifies an architectural approach, the requirements and design guidelines to built service execution environments and related platforms that are fully compatible to each other. The concepts presented in this paper have been developed by the Wireless World Research Forum (WWRF) Working Group 2 (WG2) and are under permanent discussion in this forum.

Personalisation provides a convenient means to ease the use of pervasive computing systems and related services. Profiles are one of the major building blocks for making real personalisation happen. In the existing heterogeneous and upcoming pervasive computing environment typically numerous different profiles are used and maintained by the user or different services, devices or operators. In order to avoid multiple copies of the same data profile synchronisation and linking should be used and applied between the different locations and administrative domains, in which the different types of profiles reside. But keeping in mind the different contexts', in which these profiles have been constructed, it is mostly unknown how to match the meaning of one profile to another or how to harmonize the different kind of values in the different profiles. In this paper, mechanisms for efficient synchronisation of profiles based on semantic distinctions are introduced. By using ontology's to distinguish between semantic entities profiles can be kept synchronous even using low-bandwidth radio links and mobile devices like smart-phones and PDAs.

User profiles are typically stored locally within proprietary personalisation architectures at service providers. Replicating the same information of the user profile, e.g. email address, across multiple independent service providers decreases consistency of user profiles. Centralising or exchange profile information increases consistency of profiles. Law issues, company policies and proprietary profile structures prevent successful profile exchange between service providers. Existing solutions for centralised profile storage like Microsoft Passport or Liberty Alliance are limited to specific information in the user's profile, e.g. authentication information. This paper presents a profile architecture allowing to keep the user's full profile in the user domain. Service providers access the user profile by defined translations between the service providers profile structure and the user's profile structure. The translations defined are adaptable to reflect modifications in the different profile structures, e.g. Amazon, eBay etc. The concepts developed are especially interesting for facilitating future mobile applications.
