@inbook{47421, abstract = {{Class expression learning in description logics has long been regarded as an iterative search problem in an infinite conceptual space. 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. We provide our source code, datasets, and pretrained models at https://github.com/dice-group/NCES2.}}, author = {{Kouagou, N'Dah Jean and Heindorf, Stefan and Demir, Caglar and Ngonga Ngomo, Axel-Cyrille}}, booktitle = {{Machine Learning and Knowledge Discovery in Databases: Research Track}}, isbn = {{9783031434204}}, issn = {{0302-9743}}, location = {{Turin}}, publisher = {{Springer Nature Switzerland}}, title = {{{Neural Class Expression Synthesis in ALCHIQ(D)}}}, doi = {{10.1007/978-3-031-43421-1_12}}, year = {{2023}}, } @article{42679, abstract = {{The Saharan desert ant Cataglyphis bombycina is densely covered with shiny silver setae (hair-like structures).

This work provides additional data on microstructural details of the setae that are used to simulate the scattering of an individual seta to explain their influence on the optical properties. This is achieved by characterization of their structure using light microscopy and scanning/transmission electron microscopy. How the microstructural features influence scattering is investigated wave-optically within the limits of finite-difference time-domain simulations from the ultraviolet to the mid-infrared spectral range to elucidate the optical effects beyond ray optics and effective medium theory. The results show that Mie scattering plays an important role in protecting the ant from solar radiation and could be relevant for its thermal tolerance.}}, author = {{Schwind, Bertram and Wu, Xia and Tiemann, Michael and Fabritius, Helge-Otto}}, issn = {{0740-3224}}, journal = {{Journal of the Optical Society of America B}}, keywords = {{Atomic and Molecular Physics, and Optics, Statistical and Nonlinear Physics}}, number = {{3}}, pages = {{B49 -- B58}}, publisher = {{Optica Publishing Group}}, title = {{{Broadband Mie scattering effects by structural features of setae from the Saharan silver ant Cataglyphis bombycina}}}, doi = {{10.1364/josab.474899}}, volume = {{40}}, year = {{2023}}, } @inproceedings{46988, abstract = {{Extremwettersituationen sind durch die Kombination von globalen und lokalen Wirkzusammenhän-gen gekennzeichnet.

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{51338, author = {{Schütte, Jan and Sextro, Walter}}, booktitle = {{20.

Research and Development (R&D) plays a vital role in innovation. As technology advances and product life cycles become shorter, firms rely on R&D as a strategy to invigorate innovation. R&D project portfolio selection is a complex and challenging task. Despite the management's efforts to implement the best project portfolio selection practices, many projects continue to fail or miss their target. The problem is that selecting R&D projects requires a deep understanding of strategic vision and technical capabilities. However, many decision-makers lack technological insight or strategic vision. This article aims to provide a method to capitalize on the expertise of R&D professionals to assist managers in making informed and effective decisions. It also provides a framework for aligning the portfolio of R&D projects with the organizational vision and mission.Design/methodology/approachThis article proposes a new strategic approach for R&D project portfolio selection using efficiency-uncertainty maps.FindingsThe proposed strategy plane helps decision-makers align R&D project portfolios with their strategies to combine a strategic view and numerical analysis in this research. The proposed strategy plane consists of four areas: Exploitation Zone, Challenge Zone, Desperation Zone and Discretion Zone. Mapping the project into this strategic plane would help decision-makers align their project portfolio according to the corporate perspectives.Originality/valueThe new approach combines the efficiency and uncertainty dimensions in portfolio selection into an integrated framework that: (i) provides a complete representation of the stochastic decision-making processes, (ii) models the endogenous uncertainty inherent in the project selection process and (iii) proposes a computationally practical and visually unique solution procedure for classifying desirable and undesirable R&D projects.}}, author = {{Namazi, Mehdi and Tavana, Madjid and Mohammadi, Emran and Bonyadi Naeini, Ali}}, issn = {{1463-5771}}, journal = {{Benchmarking: An International Journal}}, keywords = {{Business and International Management, Strategy and Management}}, number = {{10}}, pages = {{4193--4220}}, publisher = {{Emerald}}, title = {{{A new strategic approach for R&D project portfolio selection using efficiency-uncertainty maps}}}, doi = {{10.1108/bij-02-2022-0129}}, volume = {{30}}, 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}}, } @article{39976, abstract = {{The context of the study is the increasing digitalisation of the living environment of primary school students, which is to be introduced into primary schools according to theoretical and educational policy guidelines. In this regard, further teacher training on digital media in classrooms are particularly relevant, on the one hand to promote teachers’ digital-related pedagogical knowledge and content knowledge (DPaCK). On the other hand, studies also reveal positive correlations among teacher training, teaching activities, and students’ learning outcomes. In-service teacher training courses with adaptive support by a trainer in particular have proven to be effective. Against the background of various research studies on professional development of teachers, a corresponding model of tripartite learning outcomes has been established and serves as a broad theoretical framework. However, the specific relationship between in-service teacher training with adaptive support, DPaCK, and computational thinking of primary school students in the context of the German primary school subject Sachunterricht has not been sufficiently studied. Therefore, the following research questions can be derived: (1) To what extent does training with adaptive support on the topic of learning robots contribute to the development of teachers’ DPaCK? (2) Which effects can be ascertained on the students’ computational thinking in technology-related Sachunterricht? To investigate this relationship, an intervention study in a pre-post design with an experimental group, a control group, and a baseline is appropriate.
