Typically, appropriate trust encompasses that humans trust AI except for instances in which they either explicitly notice AI errors or are suspicious that errors could be present. So far, appropriate trust or related notions have mainly been investigated by assessing trust and reliance. In this contribution, we argue that these assessments are insufficient to measure the complex aim of appropriate trust and the related notion of healthy distrust. We introduce and test the perspective of covert visual attention as an additional indicator for appropriate trust and draw conceptual connections to the notion of healthy distrust. To test the validity of our conceptualization, we formalize visual attention using the Theory of Visual Attention and measure its properties that are potentially relevant to appropriate trust and healthy distrust in an image classification task. Based on temporal-order judgment performance, we estimate participants' attentional capacity and attentional weight toward correct and incorrect mock-up AI classifications. We observe that misclassifications reduce attentional capacity compared to correct classifications. However, our results do not indicate that this reduction is beneficial for a subsequent judgment of the classifications. The attentional weighting is not affected by the classifications' correctness but by the difficulty of categorizing the stimuli themselves. We discuss these results, their implications, and the limited potential for using visual attention as an indicator of appropriate trust and healthy distrust.","lang":"eng"}],"volume":16,"author":[{"orcid":"0009-0008-5193-6243","last_name":"Peters","full_name":"Peters, Tobias Martin","id":"92810","first_name":"Tobias Martin"},{"orcid":"0000-0002-2879-2359","last_name":"Biermeier","id":"55908","full_name":"Biermeier, Kai","first_name":"Kai"},{"first_name":"Ingrid","id":"451","full_name":"Scharlau, Ingrid","orcid":"0000-0003-2364-9489","last_name":"Scharlau"}],"date_created":"2026-01-14T14:21:59Z","date_updated":"2026-01-14T14:29:03Z","publisher":"Frontiers Media SA","doi":"10.3389/fpsyg.2025.1694367","title":"Assessing healthy distrust in human-AI interaction: interpreting changes in visual attention","publication_identifier":{"issn":["1664-1078"]},"publication_status":"published","intvolume":"        16","citation":{"ama":"Peters TM, Biermeier K, Scharlau I.

Process mining relies on event logs that capture explicit process knowledge; however, knowledge-intensive processes (KIPs) in domains such as healthcare and product development depend on tacit knowledge, which is often absent from event logs. To bridge this gap, this study proposes a LLM-based framework for mobilizing tacit process knowledge and enriching event logs. A proof-of-concept is demonstrated using a KIP-specific LLM-driven conversational agent built on GPT-4o. The results indicate that LLMs can capture tacit process knowledge through targeted queries and systematically integrate it into event logs. This study presents a novel approach combining LLMs, knowledge management, and process mining, advancing the understanding and management of KIPs by enhancing knowledge accessibility and documentation.","lang":"eng"}],"publication":"AMCIS 2025 Proceedings. 11.","type":"conference","language":[{"iso":"eng"}],"keyword":["Process Mining","Large Language Model","Knowledge Management","Knowledge-Intensive Process","Tacit Knowledge"],"department":[{"_id":"196"}],"user_id":"51905","_id":"60958","citation":{"mla":"Brennig, Katharina. “Revealing the Unspoken: Using LLMs to Mobilize and Enrich Tacit Knowledge in Event Logs of Knowledge-Intensive Processes.” <i>AMCIS 2025 Proceedings. 11.</i>, 2025.","short":"K.

Building on theories of enactive cognition and sensorimotor contingency theory, we experimentally manipulated action sequences (action history) to create either simple or rich “situational models,” and investigated how these models interact with attention and reflect in linguistic processes during human–robot interaction. Participants (N = 30) engaged in a controlled object placement task with a humanoid robot, where the action (manner) information was either provided or omitted. The omission elicited repair behaviors in participants that were in focus of our investigation. For rich models (competing action possibilities) participants demonstrated: a) increased attentional reorientation, reflecting active engagement with the situational model b) preference for restricted repairs, targeting the specific source of trouble in action selection. Conversely, a simple situational model led to more generalized attention patterns and open repair strategies, suggesting weaker constraints on internal processing. These findings highlight how situational structures emerge externally to scaffold internal cognitive processes, with action histories serving as a crucial context for the interface between perception, action, and language. We discuss how to implement such a tight loop in the assistance of a system."}],"publication":"IEEE International Conference on Development and Learning (ICDL)","language":[{"iso":"eng"}],"keyword":["Attention","Action","Repairs","Task model","HRI","Eyemovement"],"year":"2025","quality_controlled":"1","title":"Manners Matter: Action history guides attention and repair choices during interaction","date_created":"2025-09-24T12:32:52Z"},{"place":"Cham","citation":{"ama":"Demir C, Yekini M, Röder M, Mahmood Y, Ngonga Ngomo A-C.

Yet, deep-learning-based models are only post-hoc and locally explainable. In contrast, learning Web Ontology Language (OWL) class  expressions  in  Description  Logics  (DLs)  is  ante-hoc  and  globally explainable. However, state-of-the-art learners have two well-known lim-itations:  scaling  to  large  knowledge  graphs  and  handling  missing  infor-mation.  Here,  we  present  a  decision-tree-based  learner  (tDL)  to  learn Web  Ontology  Languages  (OWLs)  class  expressions  over  large  knowl-edge graphs, while imputing missing triples. Given positive and negative example individuals, tDL  firstly constructs unique OWL expressions in .SHOIN from  concise  bounded  descriptions  of  individuals.  Each  OWL class expression is used as a feature in a binary classification problem to represent input individuals. Thereafter, tDL  fits a CART decision tree to learn Boolean decision rules distinguishing positive examples from nega-tive examples. A final OWL expression in.SHOIN is built by traversing the  built  CART  decision  tree  from  the  root  node  to  leaf  nodes  for  each positive example. By this, tDL  can learn OWL class expressions without exploration, i.e., the number of queries to a knowledge graph is bounded by the number of input individuals. Our empirical results show that tDL outperforms  the  current state-of-the-art  models  across datasets. Impor-tantly, our experiments over a large knowledge graph (DBpedia with 1.1 billion triples) show that tDL  can effectively learn accurate OWL class expressions,  while  the  state-of-the-art  models  fail  to  return  any  results. Finally,  expressions  learned  by  tDL  can  be  seamlessly  translated  into natural language explanations using a pre-trained large language model and a DL verbalizer."}],"publication":"Lecture Notes in Computer Science","keyword":["Decision Tree","OWL Class Expression Learning","Description Logic","Knowledge Graph","Large Language Model","Verbalizer"],"language":[{"iso":"eng"}]},{"publication":"Chemical Engineering Science","abstract":[{"lang":"eng","text":"Sandwich packings are assembled from two conventional structured packings with different geometrical surface areas stacked alternatingly within a separation column.

The goal is to reconfigure a set of tiles into a specific shape termed an icicle. The icicle, identified as a dense, hole-free structure, is strategically chosen to function as an intermediate shape for more intricate shape formation tasks. It is designed for easy exploration by a finite state agent, enabling the identification of tiles that can be lifted without breaking connectivity. Compared to the line shape, the icicle presents distinct advantages, including a reduced diameter and the presence of multiple removable tiles. We propose an algorithm that transforms an arbitrary initially connected tile structure into an icicle in 𝒪(n³) steps, matching the runtime of the line formation algorithm from prior work. Our theoretical contribution is accompanied by an extensive experimental analysis, indicating that our algorithm decreases the diameter of tile structures on average."}],"editor":[{"full_name":"Casteigts, Arnaud","last_name":"Casteigts","first_name":"Arnaud"},{"first_name":"Fabian","last_name":"Kuhn","full_name":"Kuhn, Fabian"}],"status":"public"},{"language":[{"iso":"eng"}],"file_date_updated":"2024-05-02T08:54:21Z","ddc":["000"],"keyword":["Software security","maturity model"],"user_id":"55800","department":[{"_id":"662"}],"_id":"53811","file":[{"date_updated":"2024-05-02T08:54:21Z","date_created":"2024-05-02T08:54:21Z","creator":"staaibi","file_size":540990,"file_name":"AMCIS2024_final_submission_maturity model security belt paper.pdf","file_id":"53812","access_level":"closed","content_type":"application/pdf","success":1,"relation":"main_file"}],"status":"public","abstract":[{"lang":"eng","text":"Persistent security challenges plague DevOps teams due to a deficiency in expertise regarding security tools and methods, as evidenced by frequent security incidents.

The phenomenon of coupling between task and the partner model becomes especially interesting in the context of Human– Robot Interaction where humans have to deal with unknown ca- pabilities of the robot, which can momentarily be perceived when the robot is unable to contribute to the task. Following research on the path over manner prominence in an action [31–33], a robot ex- plained actions to a human by emphasizing two aspects – the path (\"where\" component) and the manner (\"how\" component). On criti- cal trials, the robot occasionally omitted one of these components where participants sought missing information for the path or the manner. Participants’ information-seeking and gaze behaviour were analysed. Analysis confirms the initial predictions for, a) task model (path over manner prominence), i.e., earlier information-seeking for path-missing than manner-missing trials, and b) partner model, i.e., while information-seeking is predominantly tied to the attention on the robot’s face, when robot fails to provide resolution, attention shifts more often towards its torso – a behavior likely to indicate an exploration of the robot’s capabilities. An individual-level anal- ysis further confirms that the intra-individual variation in the task model is partly influenced by the perceived capability of the robot.","lang":"eng"}],"status":"public","date_updated":"2024-11-06T10:56:34Z","author":[{"full_name":"Singh, Amit","id":"91018","orcid":"0000-0002-7789-1521","last_name":"Singh","first_name":"Amit"},{"first_name":"Katharina J.","last_name":"Rohlfing","full_name":"Rohlfing, Katharina J.","id":"50352"}],"date_created":"2024-10-17T09:35:32Z","title":"Coupling of Task and Partner Model: Investigating the Intra-Individual Variability in Gaze during Human–Robot Explanatory Dialogue","conference":{"location":"San Jose, Costa Rica","name":"26th ACM International Conference on Multimodal Interaction (ICMI 2024)"},"doi":"10.1145/3686215.3689202","has_accepted_license":"1","year":"2024","citation":{"apa":"Singh, A., &#38; Rohlfing, K.

It consists of a complex Angular Central Gaussian Mixture Model (cACGMM) for speech source separation, and a von-Mises-Fisher Mixture Model (VMFMM) for diarization in a joint statistical framework. Through the integration, both spatial and spectral information are exploited for diarization and separation. We also develop a method for counting the number of active speakers in a segment of a meeting to support block-wise processing. While the total number of speakers in a meeting may be known, it is usually not known on a per-segment level. With the proposed speaker counting, joint diarization and source separation can be done segment-by-segment, and the permutation problem across segments is solved, thus allowing for block-online processing in the future. Experimental results on the LibriCSS meeting corpus show that the integrated approach outperforms a cascaded approach of diarization and speech enhancement in terms of WER, both on a per-segment and on a per-meeting level."}],"file":[{"file_size":259907,"file_name":"main.pdf","access_level":"closed","file_id":"60930","date_updated":"2025-08-14T08:11:57Z","creator":"cord","date_created":"2025-08-14T08:11:57Z","success":1,"relation":"main_file","content_type":"application/pdf"}],"publication":"ICASSP 2025 - 2025 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)","keyword":["diarization","source separation","mixture model","meeting"],"ddc":["000"],"language":[{"iso":"eng"}]},{"status":"public","type":"journal_article","article_number":"102235","article_type":"original","file_date_updated":"2024-04-30T12:34:35Z","funded_apc":"1","project":[{"grant_number":"160364472","name":"SFB 901: SFB 901: On-The-Fly Computing - Individualisierte IT-Dienstleistungen in dynamischen Märkten ","_id":"1"},{"_id":"3","name":"SFB 901 - B: SFB 901 - Project Area B"},{"grant_number":"160364472","_id":"9","name":"SFB 901 - B1: SFB 901 - Parametrisierte Servicespezifikation (Subproject B1)"}],"_id":"53801","user_id":"58701","department":[{"_id":"579"}],"citation":{"apa":"Kersting, J., Maoro, F., &#38; Geierhos, M.

For two different downstream tasks, we use data reported to be gender biased and aggregate it with annotations. First, we propose a new approach to aspect-based sentiment analysis that allows identifying, extracting, and classifying implicit and explicit aspect phrases and their polarity within a single model. The second task we present is grade prediction, where we predict the overall grade of a review on the basis of the review text. For both tasks, we train numerous transformer models and evaluate their performance. The aggregation of sensitive attributes, such as a physician’s gender and migration background, with individual text reviews allows us to measure the performance of the models with respect to these sensitive groups. These group-wise performance measures act as extrinsic bias measures for our downstream tasks. In addition, we translate several gender-specific templates of the intrinsic bias metrics into the German language and evaluate our fine-tuned models. Based on this set of tasks, fine-tuned models, and intrinsic and extrinsic bias measures, we perform correlation analyses between intrinsic and extrinsic bias measures. In terms of sensitive groups and effect sizes, our bias measure results show different directions. Furthermore, correlations between measures of intrinsic and extrinsic bias can be observed in different directions. This leads us to conclude that gender-biased data does not inherently lead to biased models. Other variables, such as template dependency for intrinsic measures and label distribution in the data, must be taken into account as they strongly influence the metric results. Therefore, we suggest that metrics and templates should be chosen according to the given task and the biases to be assessed.

By its application, increased reliability as well as reduced risks and costs can be achieved. Based on different approaches, technical systems are monitored and measured data is analyzed to enable condition-based or predictive maintenance. To this end, machine learning approaches are usually implemented to diagnose the health states or predict the health index of the monitored system. However, these trained models are often black-box models, not intuitively explainable for a human. To overcome this shortcoming, a model-based approach based on physics is developed for piezoelectric bending actuators. Such a model enables a transparent representation of the system. Moreover, the model-based approach is extended by a parameter-estimation to account for sudden changes in behavior e. g. caused by occurring cracks.","lang":"eng"}],"date_created":"2023-05-09T09:49:44Z","publisher":"Elsevier BV","title":"Model-based condition monitoring of piezoelectric bending actuators","quality_controlled":"1","year":"2023","user_id":"54290","department":[{"_id":"151"}],"_id":"44672","article_number":"114399","article_type":"original","type":"journal_article","status":"public","author":[{"first_name":"Amelie","last_name":"Bender","full_name":"Bender, Amelie","id":"54290"}],"volume":357,"date_updated":"2023-05-09T09:53:31Z","oa":"1","main_file_link":[{"open_access":"1","url":"https://authors.elsevier.com/a/1h2WV3IC9dF7Hm"}],"doi":"10.1016/j.sna.2023.114399","publication_status":"published","publication_identifier":{"issn":["0924-4247"]},"citation":{"ieee":"A.

Second, the knowledge is used to compose a development method based on the company’s situation. Third, the development method is enacted to develop a business model. This demonstration paper presents a tool-support called Situational Business Model Developer that supports all stages of our approach. We release the tool under open-source and evaluate it with a case study on developing business models for mobile apps.","lang":"eng"}],"status":"public","publication":"Proceedings of the 17th International Conference on Wirtschaftsinformatik","type":"conference","keyword":["Business Model Development","Situational Method Engineering","Tool Support"],"language":[{"iso":"eng"}],"_id":"29839","project":[{"name":"SFB 901: SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - C: SFB 901 - Project Area C"},{"_id":"17","name":"SFB 901 - C5: SFB 901 - Subproject C5"}],"department":[{"_id":"66"},{"_id":"534"}],"user_id":"47208"},{"oa":"1","date_updated":"2022-07-04T12:34:53Z","author":[{"full_name":"Gottschalk, Sebastian","id":"47208","last_name":"Gottschalk","first_name":"Sebastian"},{"last_name":"Yigitbas","orcid":"0000-0002-5967-833X","id":"8447","full_name":"Yigitbas, Enes","first_name":"Enes"},{"first_name":"Gregor","last_name":"Engels","full_name":"Engels, Gregor","id":"107"}],"conference":{"end_date":"2022-03-15","location":"Hawaii","name":"18th International Conference on Software Architecture ","start_date":"2022-03-12"},"doi":"10.1109/ICSA-C54293.2022.00011","has_accepted_license":"1","citation":{"chicago":"Gottschalk, Sebastian, Enes Yigitbas, and Gregor Engels. “Model-Driven Continuous Experimentation on Component-Based Software Architectures .” In <i>Proceedings of the 18th International Conference on Software Architecture Companion </i>.

This discovery can be achieved with continuous experimentation, testing different software variants with distinct user groups, and deploying the superior variant for all users. However, existing approaches do not focus on explicit modeling of variants and experiments, which offers advantages such as traceability of decisions and combinability of experiments. Therefore, our vision is the provision of model-driven continuous experimentation, which provides the developer with a framework for structuring the experimentation process. For that, we introduce the overall concept, apply it to the experimentation on component-based software architectures and point out future research questions. In particular, we show the applicability by combining feature models for modeling the software variants, users, and experiments (i.e., model-driven) with MAPE-K for the adaptation (i.e., continuous experimentation) and implementing the concept based on the component-based Angular framework.","lang":"eng"}],"file":[{"file_size":183185,"file_id":"32322","access_level":"open_access","file_name":"ICSA_CR.pdf","date_updated":"2022-07-04T12:34:52Z","creator":"sego","date_created":"2022-07-04T12:33:18Z","relation":"main_file","content_type":"application/pdf"}]},{"conference":{"name":"IEEE/IFIP Network Operations and Management Symposium (NOMS)","start_date":"2022-04-25","end_date":"2022-04-29","location":"Budapest"},"author":[{"first_name":"Stefan","last_name":"Werner","full_name":"Werner, Stefan"},{"orcid":"0000-0001-8210-4011","last_name":"Schneider","full_name":"Schneider, Stefan Balthasar","id":"35343","first_name":"Stefan Balthasar"},{"last_name":"Karl","full_name":"Karl, Holger","id":"126","first_name":"Holger"}],"date_updated":"2022-01-11T08:44:04Z","oa":"1","citation":{"apa":"Werner, S., Schneider, S.

Providing such services requires to decide how often to instantiate each component, where to place these instances in the network, how to chain them and route traffic through them. \r\nTo overcome limitations of conventional, hardwired heuristics, deep reinforcement learning (DRL) approaches for self-learning network and service management have emerged recently. These model-free DRL approaches are more flexible but typically learn tabula rasa, i.e., disregard existing understanding of networks, services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel model-based AI approach that leverages existing understanding of networks and services for more efficient and effective coordination without time-intensive training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic model. This allows FutureCoord to estimate the impact of future incoming traffic and effectively optimize long-term effects, taking fluctuating demand and Quality of Service (QoS) requirements into account. Our extensive evaluation based on real-world network topologies, services, and traffic traces indicates that FutureCoord clearly outperforms state-of-the-art model-free and model-based approaches with up to 51% higher flow success ratios.","lang":"eng"}],"publication":"IEEE/IFIP Network Operations and Management Symposium (NOMS)"},{"doi":"10.1016/b978-0-12-819728-8.00047-4","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/B9780128197288000474"}],"title":"Piezoelectric Ultrasonic Power Transducers","date_created":"2022-09-30T09:35:16Z","author":[{"last_name":"Hemsel","full_name":"Hemsel, Tobias","id":"210","first_name":"Tobias"},{"full_name":"Twiefel, Jens","last_name":"Twiefel","first_name":"Jens"}],"publisher":"Elsevier","date_updated":"2022-09-30T09:41:47Z","citation":{"mla":"Hemsel, Tobias, and Jens Twiefel. “Piezoelectric Ultrasonic Power Transducers.” <i>Reference Module in Materials Science and Materials Engineering</i>, Elsevier, 2022, doi:<a href=\"https://doi.org/10.1016/b978-0-12-819728-8.00047-4\">10.1016/b978-0-12-819728-8.00047-4</a>.","short":"T.

After a short introduction including historical development, the first focus is on theoretical background of the operating principle, design and mechanical modeling. As piezoelectric elements transform electrical to mechanical energy and vice versa, equivalent circuit modeling is also described. After that, sample applications are delineated by the matter wherein ultrasound generates unique effects: incredible high pressure level as well in air as in water, micro-bubbles generating temperature peaks for very short time instances in fluids, acoustoplastic effect, enhancement of diffusion and recrystallization in solids, friction manipulation, incremental deformation and micro-cracking of surfaces, or even generation of macroscopic movements in motors. At the end, some future directions ranging from novel modeling approaches to advanced control and new materials are addressed."}],"publication":"Reference Module in Materials Science and Materials Engineering","type":"book_chapter"}]
