After completing a PhD thesis in the field of semantic indexing of multilingual documents, I joined the Information Systems Engineering Laboratory (LISI which became LIRIS in January 2003) in September 2002. Since then, I have been working on the design and use of ontologies and knowledge representation in information systems. This research theme is broken down into 2 application areas:
geographic information systems under the responsibility of Robert LAURINI (BD team from LIRIS) then François PINET from INRAE (team COPAIN from TSCF)
document management systems and information retrieval systems under the responsibility of Sylvie CALABRETTO (DRIM team from LIRIS ).
Working on several types of information systems led me to develop a new classification of ontologies to explain their different uses and the impacts of these uses on their content [RN3, CI19, AA11]. Thus, my work is focused on 3 different types of ontologies: terminological ontologies used in information retrieval systems, data ontologies used to solve interoperability issues in data exchanges between different information systems and logical ontologies to validate domain models. Currently part of my work is focused on the use of ontologies in wireless sensor networks.
All the ontologies and datasets that I have developped or participate in are available on the web site ontology.inrae.fr.
