Séminaire DKM - Ontologies for Data Access and Data Quality

Ontologies for Data Access and Data Quality

 

The main goal of this talk is to provide a gentle introduction to ontology-based mediated query answering, a promising approach to data access and integration that has been extensively studied by the knowledge representation & reasoning and database communities. In a nutshell, the idea is to use ontologies to enrich and unify the vocabulary of data sources, thereby making it easier for users to formulate their queries, as  well as to specify domain knowledge, which can be exploited by reasoning algorithms to infer implicit information and return more complete results. Towards the end of the talk, I will consider ontologies in the context of data quality and provide a quick glimpse at some recent and ongoing work on handling inconsistent data.

 

Bonus : Présentation du GDR RADIA

 

Après son exposé scientifique, Meghyn prendra quelques minutes pour présenter le GDR RADIA (Raisonnement, Apprentissage, et Décision en IA), qui est la nouvelle mouture de l'ancien GDR IA. Cette structure est un outil d'animation de la recherche française autour de l'IA et propose de nombreuses activités.
