Institute for AIIs complex query answering really complex? A paper at the International Conference on Machine Learning (<a href="https://xn--baw-joa.social/tags/ICML2025" class="mention hashtag" rel="nofollow noopener" target="_blank">#ICML2025</a>) presented by Cosimo Gregucci, PhD student at <a href="https://xn--baw-joa.social/@UniStuttgartAI" class="u-url mention" rel="nofollow noopener" target="_blank">@UniStuttgartAI</a> <a href="https://xn--baw-joa.social/@Uni_Stuttgart" class="u-url mention" rel="nofollow noopener" target="_blank">@Uni_Stuttgart</a>, discussed this question.In this paper, Cosimo Gregucci, Bo Xiong, Daniel Hernández (<a href="https://mstdn.degu.cl/@daniel" class="u-url mention" rel="nofollow noopener" target="_blank">@daniel</a>), Lorenzo Loconte, Pasquale Minervini (<a href="https://sigmoid.social/@pminervini" class="u-url mention" rel="nofollow noopener" target="_blank">@pminervini</a>), Steffen Staab, and Antonio Vergari (<a href="https://ellis.social/@nolovedeeplearning" class="u-url mention" rel="nofollow noopener" target="_blank">@nolovedeeplearning</a>) reveal that the “good” performance of SoTA approaches predominantly comes from answers that can be boiled down to single link prediction. Current neural and hybrid solvers can exploit (different) forms of triple memorization to make complex queries much easier. The authors confirm this by reporting the performance of these methods in a stratified analysis and by proposing a hybrid solver, CQD-Hybrid, which, while being a simple extension of an old method like CQD, can be very competitive against other SoTA models.The paper proposed a way to make query answering benchmarks more challenging in order to advance science.<a href="https://arxiv.org/abs/2410.12537" rel="nofollow noopener" translate="no" target="_blank">https://arxiv.org/abs/2410.12537</a><a href="https://xn--baw-joa.social/tags/KnowledgeGraphs" class="mention hashtag" rel="nofollow noopener" target="_blank">#KnowledgeGraphs</a> <a href="https://xn--baw-joa.social/tags/QueryAnswering" class="mention hashtag" rel="nofollow noopener" target="_blank">#QueryAnswering</a> <a href="https://xn--baw-joa.social/tags/ArtificialIntelligence" class="mention hashtag" rel="nofollow noopener" target="_blank">#ArtificialIntelligence</a> <a href="https://xn--baw-joa.social/tags/MachineLearning" class="mention hashtag" rel="nofollow noopener" target="_blank">#MachineLearning</a> <a href="https://xn--baw-joa.social/tags/Benchmarking" class="mention hashtag" rel="nofollow noopener" target="_blank">#Benchmarking</a> <a href="https://xn--baw-joa.social/tags/CQA" class="mention hashtag" rel="nofollow noopener" target="_blank">#CQA</a>

Harald SackTomorrow, we will dive deeper into ontologies with OWL, the Web Ontology Language. However, I'm doing OWL-lectures now for almost 20 years - and OWL as well as the lecture haven't changed much. So, I'm afraid I'm going to surprise/dissapoint the students tomorrow, when I will switch off the presentation and start improvising a random OWL ontology with them on the blackboard ;-) <a href="https://sigmoid.social/tags/ise2025" class="mention hashtag" rel="nofollow noopener" target="_blank">#ise2025</a> <a href="https://sigmoid.social/tags/OWL" class="mention hashtag" rel="nofollow noopener" target="_blank">#OWL</a> <a href="https://sigmoid.social/tags/semanticweb" class="mention hashtag" rel="nofollow noopener" target="_blank">#semanticweb</a> <a href="https://sigmoid.social/tags/semweb" class="mention hashtag" rel="nofollow noopener" target="_blank">#semweb</a> <a href="https://sigmoid.social/tags/RDF" class="mention hashtag" rel="nofollow noopener" target="_blank">#RDF</a> <a href="https://sigmoid.social/tags/knowledgegraphs" class="mention hashtag" rel="nofollow noopener" target="_blank">#knowledgegraphs</a> <a href="https://wisskomm.social/@fiz_karlsruhe" class="u-url mention" rel="nofollow noopener" target="_blank">@fiz_karlsruhe</a> <a href="https://sigmoid.social/@fizise" class="u-url mention" rel="nofollow noopener" target="_blank">@fizise</a> <a href="https://fedihum.org/@tabea" class="u-url mention" rel="nofollow noopener" target="_blank">@tabea</a> <a href="https://fedihum.org/@sourisnumerique" class="u-url mention" rel="nofollow noopener" target="_blank">@sourisnumerique</a> <a href="https://sigmoid.social/@enorouzi" class="u-url mention" rel="nofollow noopener" target="_blank">@enorouzi</a>

Harald KlinkeNew case study on how LLMs support knowledge graph creation for historical bookbinding: “Stitching History into Semantics” presents BookBindKG, a Neo4j-based framework for documenting 19th-century Greek bookbinding with LLM-generated ontologies, Cypher queries, and semantic reasoning.
