ROCES: Robust Class Expression Synthesis in Description Logics via Iterative Sampling

IJCAI 2024poster

We consider the problem of class expression learning using cardinality-minimal sets of examples. Recent class expression learning approaches employ deep neural networks and have demonstrated tremendous performance improvements in execution time and quality of the computed solutions. However, they la…

CausalQA: A Benchmark for Causal Question Answering

COLING 2022main

At least 5% of questions submitted to search engines ask about cause-effect relationships in some way. To support the development of tailored approaches that can answer such questions, we construct Webis-CausalQA-22, a benchmark corpus of 1.1 million causal questions with answers. We distinguish dif…
