This creates new challenges for organizations trying to consistently deliver high-quality customer experiences. In this paper we conduct an empirical analysis of customers’ preferences and their willingness-to-pay for different degrees of process transparency, using the example of digitally-enabled business-to-customer delivery services. Applying conjoint analysis, we quantify customers’ preferences and willingness-to-pay for different service attributes and levels. Our contributions are two-fold: For research, we provide empirical measurements of customers’ preferences and their willingness-to-pay for process transparency, suggesting that more is not always better. Additionally, we provide a blueprint of how conjoint analysis can be applied to study design decisions regarding changing an organization’s digital line of visibility. For practice, our findings enable service managers to make decisions about process transparency and establishing different levels of service quality.\r\n"}]},{"publication":"Business Process Management Workshops","citation":{"ama":"Brennig K, Benkert K, Löhr B, Müller O.

Even though process mining is increasingly relevant in academia and organizations, achieving process mining excellence and generating business value through its application is elusive. Maturity models can help to manage interdisciplinary teams in their efforts to plan, implement, and manage process mining in organizations. However, while numerous maturity models on business process management (BPM) are available, recent calls for process mining maturity models indicate a gap in the current knowledge base. We systematically design and develop a comprehensive process mining maturity model that consists of five factors comprising 23 elements, which organizations need to develop to apply process mining sustainably and successfully. We contribute to the knowledge base by the exaptation of existing BPM maturity models, and validate our model through its application to a real-world scenario.","lang":"eng"}],"main_file_link":[{"url":"https://aisel.aisnet.org/ecis2023_rp/256/"}],"_id":"50459","language":[{"iso":"eng"}],"user_id":"56760","year":"2023","title":"A Process Mining Maturity Model: Enabling Organizations to Assess and Improve their Process Mining Activities","status":"public","author":[{"full_name":"Brock, Jonathan","first_name":"Jonathan","last_name":"Brock"},{"id":"56760","full_name":"Löhr, Bernd","orcid":"0000-0001-9581-4602","first_name":"Bernd","last_name":"Löhr"},{"first_name":"Katharina","last_name":"Brennig","full_name":"Brennig, Katharina","id":"51905"},{"last_name":"Seger","first_name":"Thilo","full_name":"Seger, Thilo"},{"full_name":"Bartelheimer, Christian","last_name":"Bartelheimer","first_name":"Christian","id":"49160"},{"full_name":"von Enzberg, Sebastian","first_name":"Sebastian","last_name":"von Enzberg"},{"full_name":"Kühn, Arno","last_name":"Kühn","first_name":"Arno"},{"full_name":"Dumitrescu, Roman","first_name":"Roman","last_name":"Dumitrescu"}],"date_updated":"2025-05-21T08:42:16Z"},{"citation":{"mla":"Beverungen, Daniel, et al. “Digital Responsibility – a Multilevel Framework for Responsible Digitalization.” <i>Business &#38; Information Systems Engineering</i>, vol. 65, no. 4, 2023, pp. 463–74, doi:<a href=\"https://doi.org/10.1007/s12599-023-00822-x\">10.1007/s12599-023-00822-x</a>.","bibtex":"@article{Beverungen_Kundisch_Mirbabaie_Müller_Schryen_Trang_Trier_2023, title={Digital Responsibility – a Multilevel Framework for Responsible Digitalization}, volume={65}, DOI={<a href=\"https://doi.org/10.1007/s12599-023-00822-x\">10.1007/s12599-023-00822-x</a>}, number={4}, journal={Business &#38; Information Systems Engineering}, author={Beverungen, Daniel and Kundisch, Dennis and Mirbabaie, Milad and Müller, Oliver and Schryen, Guido and Trang, Simon Thanh-Nam and Trier, Matthias}, year={2023}, pages={463–474} }","ama":"Beverungen D, Kundisch D, Mirbabaie M, et al.

The proposed taxonomy gives researchers and practitioners opportunities to describe and evaluate current XAI systems with respect to interpretability and guides the future development of this class of systems.","lang":"eng"}],"citation":{"bibtex":"@inproceedings{Kucklick_2022, title={Towards a model- and data-focused taxonomy of XAI systems}, booktitle={Wirtschaftsinformatik 2022 Proceedings}, author={Kucklick, Jan-Peter}, year={2022} }","ama":"Kucklick J-P.

Among other domains, deep learning is used in real-estate appraisal, where it allows to extend the analysis from hard facts only (e.g., size, age) to also consider more implicit information about the location or appearance of houses in the form of image data. However, one downside of deep learning models is their intransparent mechanic of decision making, which leads to a trade-off between accuracy and interpretability. This limits their applicability for tasks where a justification of the decision is necessary. Therefore, in this paper, we first combine different perspectives on interpretability into a multi-dimensional framework for a socio-technical perspective on explainable artificial intelligence. Second, we measure the performance gains of using multi-view deep learning which leverages additional image data (satellite images) for real estate appraisal. Third, we propose and test a novel post-hoc explainability method called Grad-Ram. This modified version of Grad-Cam mitigates the intransparency of convolutional neural networks (CNNs) for predicting continuous outcome variables. With this, we try to reduce the accuracy-interpretability trade-off of multi-view deep learning models. Our proposed network architecture outperforms traditional hedonic regression models by 34% in terms of MAE. Furthermore, we find that the used satellite images are the second most important predictor after square feet in our model and that the network learns interpretable patterns about the neighborhood structure and density.","lang":"eng"}],"publication":"ACM Transactions on Management Information Systems","doi":"10.1145/3567430","main_file_link":[{"url":"https://dl.acm.org/doi/pdf/10.1145/3567430"}],"language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2023-01-10T05:20:18Z","article_type":"original","year":"2022","title":"Tackling the Accuracy–Interpretability Trade-off: Interpretable Deep Learning Models for Satellite Image-based Real Estate Appraisal","author":[{"id":"77066","last_name":"Kucklick","first_name":"Jan-Peter","full_name":"Kucklick, Jan-Peter"},{"id":"72849","full_name":"Müller, Oliver","last_name":"Müller","first_name":"Oliver"}],"publication_identifier":{"issn":["2158-656X","2158-6578"]},"citation":{"ama":"Kucklick J-P, Müller O.

In contrast, the literature has only begun to discuss how process mining can be applied to knowledge-intensive processes—such as product innovation processes—that involve creative activities, require organizational flexibility, depend on single actors’ decision autonomy, and target process-external goals such as customer satisfaction. Due to these differences, existing Process Mining methods cannot be applied out-of-the-box to analyze knowledge-intensive processes. In this paper, we employ Action Design Research (ADR) to design and evaluate a process mining approach for knowledge-intensive processes. More specifically, we draw on the two processes of product innovation and engineer-to-order in manufacturing contexts. We collected data from 27 interviews and conducted 49 workshops to evaluate our IT artifact at different stages in the ADR process. From a theoretical perspective, we contribute five design principles and a conceptual artifact that prescribe how process mining ought to be designed for knowledge-intensive processes in manufacturing. From a managerial perspective, we demonstrate how enacting these principles enables their application in practice."}],"citation":{"bibtex":"@inproceedings{Löhr_Brennig_Bartelheimer_Beverungen_Müller_2022, title={Process Mining of Knowledge-Intensive Processes: An Action Design Research Study in Manufacturing}, DOI={<a href=\"https://doi.org/10.1007/978-3-031-16103-2_18\">10.1007/978-3-031-16103-2_18</a>}, booktitle={International Conference on Business Process Management}, author={Löhr, Bernd and Brennig, Katharina and Bartelheimer, Christian and Beverungen, Daniel and Müller, Oliver}, year={2022} }","ama":"Löhr B, Brennig K, Bartelheimer C, Beverungen D, Müller O.

Such failures, which are quite hard to detect, are often related to a generalization problem known as shortcut learning. Yet, with state-of-the-art transformer models now being ubiquitous in financial text mining, one cannot help but wonder how reliable the results conveyed in the ever-growing literature genuinely are. Against this background, we expose, in this work, how vulnerable contemporary financial text mining approaches are to shortcut learning. Focussing on the common learning task of financial sentiment classification, we assess, using two entity-based sampling strategies and our publicly-available dataset, the discrepancies between i.i.d. and o.o.d. performance estimates of four transformer models. Our results reveal that o.o.d. performance estimates are consistently weaker than those of their i.i.d. counterparts, with the error rate increasing by as much as 29.7%, thus, demonstrating how this issue can, when overlooked, lead to misleading evaluations. Moreover, we show how additional preprocessing steps, such as entity removal and vocabulary filtering, can help reduce the effects of shortcut learning by filtering out entity-related linguistic cues.","lang":"eng"}],"citation":{"chicago":"Caron, Matthew. “Shortcut Learning in Financial Text Mining: Exposing the Overly Optimistic Performance Estimates of Text Classification Models under Distribution Shift.” In <i>2022 IEEE International Conference on Big Data (Big Data)</i>.

In this paper, we develop and evaluate PIVOT: the first such framework for team handball. Accounting for the fast-paced, dynamic nature and relative data scarcity of hand- ball, we propose a parsimonious end-to-end deep learning architecture that relies solely on tracking data. This efficient approach is capable of predicting the probability that a team will score within the near future given the fine-grained spatio-temporal distribution of all players and the ball over the last seconds of the game. Our experiments indicate that PIVOT is able to produce accurate and calibrated probability estimates, even when trained on a relatively small dataset. We also showcase two interactive applications of PIVOT for valuing actual and counterfactual player decisions and actions in real-time."}],"date_created":"2021-09-16T08:33:04Z","type":"conference","keyword":["expected possession value","handball","tracking data","time series classification","deep learning"],"department":[{"_id":"196"},{"_id":"172"}],"status":"public","year":"2021","title":"PIVOT: A Parsimonious End-to-End Learning Framework for Valuing Player Actions in Handball using Tracking Data","conference":{"start_date":"2021-09-13","name":"European Conference on Machine Learning and Principles and Practice of Knowledge Discovery (ECML PKDD 2021)","location":"Online","end_date":"2021-09-17"},"author":[{"last_name":"Müller","first_name":"Oliver","full_name":"Müller, Oliver","id":"72849"},{"id":"60721","full_name":"Caron, Matthew","first_name":"Matthew","last_name":"Caron"},{"full_name":"Döring, Michael","first_name":"Michael","last_name":"Döring"},{"full_name":"Heuwinkel, Tim","first_name":"Tim","last_name":"Heuwinkel"},{"first_name":"Jochen","orcid":"0000-0003-2683-5826","last_name":"Baumeister","full_name":"Baumeister, Jochen","id":"46"}],"date_updated":"2023-02-28T08:58:24Z","publication_status":"inpress","main_file_link":[{"url":"https://dtai.cs.kuleuven.be/events/MLSA21/papers/MLSA21_paper_muller.pdf"}],"language":[{"iso":"eng"}],"_id":"24547","user_id":"60721"},{"type":"conference","keyword":["Retail investors","GameStop","Social Networks","Reddit","WallStreetBets"],"department":[{"_id":"196"}],"date_created":"2021-09-24T09:51:35Z","abstract":[{"text":"In early 2021, the finance world was taken by storm by the dramatic price surge of the GameStop Corp. stock. This rise is being, at least in part, attributed to a group of Redditors belonging to the now-famous r/wallstreetbets (WSB) subreddit group. In this work, we set out to address if user activity on the WSB subreddit is associated with the trading volume of the GME stock. Leveraging a unique dataset containing more than 4.9 million WSB posts and comments, we assert that user activity is associated with the trading volume of the GameStop stock. We further show that posts have a significantly higher predictive power than comments and are especially helpful for predicting unusually high trading volume. Lastly, as recent events have shown, we believe that these findings have implications for retail and institutional investors, trading platforms, and policymakers, as these can have disruptive potential.","lang":"eng"}],"publication":"42nd International Conference on Information Systems (ICIS 2021)","citation":{"mla":"Caron, Matthew, et al. “To the Moon!
