Previous research in knowledge graph embeddings has focused exclusively on Clifford algebras of a specific type, which do not include nilpotent base vectors—elements that square to zero. In this work, we introduce a novel approach by incorporating nilpotent base vectors with a nilpotency index of two, leading to a more general form of Clifford algebras named degenerate Clifford algebras. This generalization to degenerate Clifford algebras does allow for covering dual numbers and as such include translations and rotations models under the same generalization paradigm for the first time. We develop two models to determine the parameters that define the algebra: one using a greedy search and another predicting the parameters based on neural network embeddings of the input knowledge graph. Our evaluation on seven benchmark datasets demonstrates that this incorporation of nilpotent vectors enhances the quality of embeddings. Additionally, our method outperforms state-of-the-art approaches in terms of generalization, particularly regarding the mean reciprocal rank achieved on validation data. Finally, we show that even a simple greedy search can effectively discover optimal or near-optimal parameters for the algebra.</jats:p>","lang":"eng"}],"status":"public","publisher":"IOS Press","date_updated":"2025-11-28T14:57:09Z","date_created":"2025-11-28T14:32:43Z","author":[{"first_name":"Louis Mozart","full_name":"Kamdem Teyou, Louis Mozart","last_name":"Kamdem Teyou"},{"last_name":"Demir","full_name":"Demir, Caglar","first_name":"Caglar"},{"first_name":"Axel-Cyrille","full_name":"Ngonga Ngomo, Axel-Cyrille","last_name":"Ngonga Ngomo"}],"title":"Embedding Knowledge Graphs in Degenerate Clifford Algebras","conference":{"name":"27TH EUROPEAN CONFERENCE ON ARTIFICIAL INTELLIGENCE","start_date":"2024-10-19","end_date":"2024-10-24","location":"Santiago de Compostela"},"doi":"10.3233/faia240627","publication_status":"published","publication_identifier":{"isbn":["9781643685489"],"issn":["0922-6389","1879-8314"]},"quality_controlled":"1","year":"2024","citation":{"apa":"Kamdem Teyou, L.

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.

Declarative link discovery frameworks use complex link specifications to express the conditions under which a link between two resources can be deemed to exist. However, understanding such complex link specifications is a challenging task for non-expert users of link discovery frameworks. In this paper, we address this drawback by devising NMV-LS, a language model-based verbalization approach for translating complex link specifications into natural language. NMV-LS relies on the results of rule-based link specification verbalization to apply continuous training on T5, a large language model based on the Transformerarchitecture. We evaluated NMV-LS on English and German datasets using well-known machine translation metrics such as BLUE, METEOR, ChrF++ and TER. Our results suggest that our approach achieves a verbalization performance close to that of humans and outperforms state of the art approaches.

It has been playing a major role in AI for decades. In logic-based argumentation, we explore the internal structure of an argument. Informally, a set of formulas is the support for a given claim if it is consistent, subset-minimal, and implies the claim. In such a case, the pair of the support and the claim together is called an argument. In this article, we study the propositional variants of the following three computational tasks studied in argumentation: ARG (exists a support for a given claim with respect to a given set of formulas), ARG-Check (is a given set a support for a given claim), and ARG-Rel (similarly as ARG plus requiring an additionally given formula to be contained in the support). ARG-Check is complete for the complexity class DP, and the other two problems are known to be complete for the second level of the polynomial hierarchy (Creignou et al. 2014 and Parson et al., 2003) and, accordingly, are highly intractable. Analyzing the reason for this intractability, we perform a two-dimensional classification: First, we consider all possible propositional fragments of the problem within Schaefer’s framework (STOC 1978) and then study different parameterizations for each of the fragments. We identify a list of reasonable structural parameters (size of the claim, support, knowledge base) that are connected to the aforementioned decision problems. Eventually, we thoroughly draw a fine border of parameterized intractability for each of the problems showing where the problems are fixed-parameter tractable and when this exactly stops. Surprisingly, several cases are of very high intractability (para-NP and beyond).</jats:p>","lang":"eng"}],"author":[{"first_name":"Yasir","id":"99353","full_name":"Mahmood, Yasir","last_name":"Mahmood"},{"full_name":"Meier, Arne","last_name":"Meier","first_name":"Arne"},{"first_name":"Johannes","last_name":"Schmidt","full_name":"Schmidt, Johannes"}],"date_created":"2024-06-04T09:58:17Z","volume":24,"date_updated":"2024-06-04T15:52:54Z","publisher":"Association for Computing Machinery (ACM)","doi":"10.1145/3582499","title":"Parameterized Complexity of Logic-based Argumentation in Schaefer’s Framework","issue":"3","publication_status":"published","publication_identifier":{"issn":["1529-3785","1557-945X"]},"citation":{"bibtex":"@article{Mahmood_Meier_Schmidt_2023, title={Parameterized Complexity of Logic-based Argumentation in Schaefer’s Framework}, volume={24}, DOI={<a href=\"https://doi.org/10.1145/3582499\">10.1145/3582499</a>}, number={3}, journal={ACM Transactions on Computational Logic}, publisher={Association for Computing Machinery (ACM)}, author={Mahmood, Yasir and Meier, Arne and Schmidt, Johannes}, year={2023}, pages={1–25} }","mla":"Mahmood, Yasir, et al. “Parameterized Complexity of Logic-Based Argumentation in Schaefer’s Framework.” <i>ACM Transactions on Computational Logic</i>, vol. 24, no. 3, Association for Computing Machinery (ACM), 2023, pp. 1–25, doi:<a href=\"https://doi.org/10.1145/3582499\">10.1145/3582499</a>.","short":"Y.

Claim-augmented argumentation frameworks (CAFs) have been introduced to deploy a conclusion-oriented perspective. CAFs expand argumentation frameworks by an additional step which involves retaining claims for an accepted set of arguments. We introduce a novel concept of a justification status for claims, a quantitative measure of extensions supporting a particular claim. The well-studied problems of credulous and skeptical reasoning can then be seen as simply the two endpoints of the spectrum when considered as a justification level of a claim. Furthermore, we explore the parameterized complexity of various reasoning problems for CAFs, including the quantitative reasoning for claim assertions. We begin by presenting a suitable graph representation that includes arguments and their associated claims. Our analysis includes the parameter treewidth, and we present decomposition-guided reductions between reasoning problems in CAF and the validity problem for QBF.</jats:p>"}],"status":"public"},{"type":"book_chapter","publication":"Logic, Language, Information, and Computation","status":"public","_id":"54579","user_id":"99353","department":[{"_id":"574"}],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"isbn":["9783031397837","9783031397844"],"issn":["0302-9743","1611-3349"]},"place":"Cham","year":"2023","citation":{"ama":"Mahmood Y, Virtema J.
