Title: Ontology-based information integration
Abstract: Providing efficient and high-level services for integrating and querying heterogeneous data sources raises many difficult challenges. Data semantics is probably one of the keys for attacking those challenges in a principled way. A lot of effort has been done in the Semantic Web community for describing the semantics of information through ontologies that provide a conceptual yet computational model of a particular domain of interest. In this talk, I will show how exploiting ontologies on top of data can help to solve several problems raised by modern data-centered applications in which data may be ubiquitous, multi-form, multi-source and multi-scale. I will also show how models and algorithms have evolved to face scalability issues and data quality challenges.
Quelques infos sur notre invité : Marie-Christine Rousset is Professor of Computer Science, member of the LIG (Laboratoire d'Informatique de Grenoble), in the SLIDE group, at the University of Grenoble Alpes in France, where she has moved from Paris-Saclay(LRI). Her areas of research are Knowledge Representation and Information Integration. In particular, she works on the following topics: ontology-based data access, logic-based mediation between distributed data sources, query rewriting using views, data linkage and distributed reasoning for the Semantic Web. She is also involved in several projects combining artificial intelligence and database techniques for information integration.
