Titre: Ontology-Mediated Query Answ=
ering: Using Rules and Reasoning to
Get More from Data

R=C3=A9sum=C3=A9: "Ontology-mediated query answ=
ering (OMQA) is a promising
approach to data access and integ=
ration that has been extensively
studied by the knowledge rep=
resentation & reasoning and database
communities. Ontolog=
ies are used to enrich and unify the vocabulary of
data sourc=
es, allowing users to formulate their queries in a more
famil=
iar vocabulary which abstracts from the specific way data is
=
stored, and to specify domain knowledge, which can be exploited by
reasoning algorithms to infer implicit information and return morecomplete query results. While the addition of an ontology bring=
s
significant benefits, it also renders the query answering t=
ask more
computationally involved. This has led both to theor=
etical studies
aimed at understanding the complexity of OMQA =
for a range of ontology
and query languages, as well as the d=
evelopment of new algorithmic
techniques. The aim of this tal=
k will be to provide a gentle
introduction to OMQA, while als=
o highlighting some recent results and
research directions.&q=
uot;

Nous tenons =C3=A0 remercier tous les GT =
qui nous ont fait remonter des
propositions de s=C3=A9minaire=
s, et tous les GT qui le feront.

Au plaisir de=
vous "voir" bient=C3=B4t.
