Each iteration of the search process invokes a reasoner and a heuristic function. The reasoner finds the instances of the current expression, and the heuristic function computes the information gain and decides on the next step to be taken. As the size of the background knowledge base grows, search-based approaches for class expression learning become prohibitively slow. Current neural class expression synthesis (NCES) approaches investigate the use of neural networks for class expression learning in the attributive language with complement (ALC). While they show significant improvements over search-based approaches in runtime and quality of the computed solutions, they rely on the availability of pretrained embeddings for the input knowledge base. Moreover, they are not applicable to ontologies in more expressive description logics. In this paper, we propose a novel NCES approach which extends the state of the art to the description logic ALCHIQ(D). Our extension, dubbed NCES2, comes with an improved training data generator and does not require pretrained embeddings for the input knowledge base as both the embedding model and the class expression synthesizer are trained jointly. Empirical results on benchmark datasets suggest that our approach inherits the scalability capability of current NCES instances with the additional advantage that it supports more complex learning problems. NCES2 achieves the highest performance overall when compared to search-based approaches and to its predecessor NCES.

They also serve as the backbone for automatic decision systems, e.g. for medical diagnostics and credit scoring. As stakeholders affected by these decisions would like to understand their situation and verify fair decisions, a number of explanation approaches have been proposed using concepts in description logics. However, the learned concepts can become long and difficult to fathom for non-experts, even when verbalized. Moreover, long concepts do not immediately provide a clear path of action to change one's situation. Counterfactuals answering the question "How must feature values be changed to obtain a different classification?" have been proposed as short, human-friendly explanations for tabular data. In this paper, we transfer the notion of counterfactuals to description logics and propose the first algorithm for generating counterfactual explanations in the description logic $\mathcal{ELH}$. Counterfactual candidates are generated from concepts and the candidates with fewest feature changes are selected as counterfactuals. In case of multiple counterfactuals, we rank them according to the likeliness of their feature combinations. For evaluation, we conduct a user survey to investigate which of the generated counterfactual candidates are preferred for explanation by participants. In a second study, we explore possible use cases for counterfactual explanations.}}, author = {{Sieger, Leonie Nora and Heindorf, Stefan and Blübaum, Lukas and Ngonga Ngomo, Axel-Cyrille}}, booktitle = {{arXiv:2301.05109}}, title = {{{Explaining ELH Concept Descriptions through Counterfactual Reasoning}}}, year = {{2023}}, } @inproceedings{54506, author = {{Lick, Jonas and Schreckenberg, Felix and Sahrhage, Philipp and Wohlers, Benedict and Klöcker, Susanne and von Enzberg, Sebastian and Kühn, Arno and Dumitrescu, Roman}}, booktitle = {{Artificial Intelligence, Social Computing and Wearable Technologies, Vol. 113}}, editor = {{Karwowsk, Waldemar and Ahram, Tareq }}, location = {{Hawaii}}, title = {{{Integrating Domain Expertise and Artificial Intelligence for Effective Supply Chain Management Planning Tasks: A Collaborative Approach}}}, year = {{2023}}, } @inproceedings{54503, author = {{Günther, Matthias and Göllner, Denis and Heihoff-Schwede, Jörg and Anacker, Harald and Dumitrescu, Roman}}, booktitle = {{Tag des Systems Engineering 2023}}, editor = {{Wilke, Daria and Koch, Walter and Kaffenberger, Rüdiger and Dreiseitel, Stefan}}, location = {{Würzburg}}, title = {{{Engineering und Management von System of Systems–Gestaltungskonzepte im SoS-Engineering}}}, year = {{2023}}, } @inproceedings{54505, author = {{Wilke, Daria and Heitmann, Rebecca and Tekaat, Julian and Anacker, Harald and Dumitrescu, Roman}}, booktitle = {{Tag des Systems Engineering 2023}}, editor = {{Wilke, Daria and Koch, Walter and Kaffenberger, Rüdiger and Dreiseitel, Stefan}}, location = {{Würzburg}}, title = {{{Reifegradmodell zur Einführung von Systems Engineering–Systemdenken als Handlungsfeld}}}, year = {{2023}}, } @inproceedings{54507, author = {{Mager, Thomas and Dumitrescu, Roman}}, location = {{Amberg}}, title = {{{Hybrid design approach for the design of high-frequency components in MID technology}}}, year = {{2023}}, } @inbook{54547, author = {{Eckertz, Daniel and Anacker, Harald and Dumitrescu, Roman}}, booktitle = {{Open Science in Engineering}}, editor = {{Auer, Michael and Langmann, Reinhard and Tsiatsos, Thrasyvoulos}}, isbn = {{9783031424663}}, issn = {{2367-3370}}, location = {{Thessaloniki}}, publisher = {{Springer Nature Switzerland}}, title = {{{Modular Toolbox for Low-Code Development of Individual Augmented Reality Applications in Unity}}}, doi = {{10.1007/978-3-031-42467-0_40}}, year = {{2023}}, } @article{54567, author = {{Schlegel, Michael and Wiederkehr, Ingrid and Rapp, Simon and Koldewey, Christian and Albers, Albert and Dumitrescu, Roman}}, issn = {{2212-8271}}, journal = {{Procedia CIRP}}, location = {{Kapstadt}}, pages = {{792--797}}, publisher = {{Elsevier BV}}, title = {{{Future-robust evolution of product portfolios: Need for action from theory and practice}}}, doi = {{10.1016/j.procir.2023.09.077}}, volume = {{120}}, year = {{2023}}, } @article{54565, author = {{Wiederkehr, Ingrid and Schlegel, Michael and Koldewey, Christian and Rapp, Simon and Dumitrescu, Roman and Albers, Albert}}, issn = {{2212-8271}}, journal = {{Procedia CIRP}}, location = {{Kapstadt}}, pages = {{816--821}}, publisher = {{Elsevier BV}}, title = {{{Interacting Forces for a Resilient, Future-robust Evolution of Product Portfolios}}}, doi = {{10.1016/j.procir.2023.09.081}}, volume = {{120}}, year = {{2023}}, }
