Davide Lanti: Data Scaling for OBDA Benchmarking

When: Friday, March 11, at 14:30 Where: Turing building, room Gilles Kahn Abstract: Ontology-based data access (OBDA) is a novel approach whose aim is to facilitate the access to legacy databases to the end-users through the help of a mediating ontology. Although some prototype implementations for OBDA exist, performance is
