Institute for AI<p>Is complex query answering really complex?

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.</p><p>The paper proposed a way to make query answering benchmarks more challenging in order to advance science.</p><p><a href="https://arxiv.org/abs/2410.12537" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">arxiv.org/abs/2410.12537</span><span class="invisible"></span></a></p><p><a href="https://xn--baw-joa.social/tags/KnowledgeGraphs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>KnowledgeGraphs</span></a> <a href="https://xn--baw-joa.social/tags/QueryAnswering" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>QueryAnswering</span></a> <a href="https://xn--baw-joa.social/tags/ArtificialIntelligence" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ArtificialIntelligence</span></a> <a href="https://xn--baw-joa.social/tags/MachineLearning" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MachineLearning</span></a> <a href="https://xn--baw-joa.social/tags/Benchmarking" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Benchmarking</span></a> <a href="https://xn--baw-joa.social/tags/CQA" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CQA</span></a></p>

Harald Sack<p>Tomorrow, 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 ;-) </p><p><a href="https://sigmoid.social/tags/ise2025" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ise2025</span></a> <a href="https://sigmoid.social/tags/OWL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OWL</span></a> <a href="https://sigmoid.social/tags/semanticweb" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>semanticweb</span></a> <a href="https://sigmoid.social/tags/semweb" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>semweb</span></a> <a href="https://sigmoid.social/tags/RDF" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RDF</span></a> <a href="https://sigmoid.social/tags/knowledgegraphs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>knowledgegraphs</span></a> <span class="h-card" translate="no"><a href="https://wisskomm.social/@fiz_karlsruhe" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>fiz_karlsruhe</span></a></span> <span class="h-card" translate="no"><a href="https://sigmoid.social/@fizise" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>fizise</span></a></span> <span class="h-card" translate="no"><a href="https://fedihum.org/@tabea" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>tabea</span></a></span> <span class="h-card" translate="no"><a href="https://fedihum.org/@sourisnumerique" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>sourisnumerique</span></a></span> <span class="h-card" translate="no"><a href="https://sigmoid.social/@enorouzi" class="u-url mention" rel="nofollow noopener" target="_blank">@<span>enorouzi</span></a></span></p>
