Meghyn Bienvenu: Assorted topics in ontology-based data access

14.00, room 455, PCRI

In this talk, I will start by recalling the basics of ontology-based data access, focusing on ontologies formulated in lightweight description logics. Afterwards, I will give a brief description of my recent work on this topic, evoking the results in the following papers:
