International audience; Ontology-mediated query answering (OMQA) consists in asking database queries on a knowledge base (KB); a KB is a set of facts, the KB's database, described by domain knowledge, the KB's ontology. FOL-rewritability is the main

International audience; Collective entity linking is a core natural language processing task, which consists in jointly identifying the entities of a knowledge base (KB) that are mentioned in a text exploiting existing relations between entities with

International audience; The proliferation of heterogeneous data sources in many application contexts brings an urgent need for expressive and efficient data integration mechanisms. There are strong advantages to using RDF graphs as the integration fo

International audience; Query answering in RDF knowledge bases has traditionally been performed either through graph saturation, i.e., adding all implicit triples to the graph, or through query reformulation, i.e., modifying the query to look for the
