Enseignement

Je réalise mes enseignements au Département d'Informatique de la Faculté des Sciences de l'Université de Poitiers. Je suis responsable de la Licence 3 Informatique. Les principaux modules dont je m'occupe concernent l'enseignement des bases de données de la Licence 3 au Master 2 :

Master 2 Informatique : Ingénierie des données
Master 2 Génie Physiologique : Entrepôts de Données et Décisionnel
Master 1 Informatique : Base de Données Avancées
Licence Professionnelle TLWTM : Bases de Données et Web

Les supports de cours sont disponibles sur la plateforme UPdago de l'ENT (accès limité).

Recherche

Thématiques

Mes recherches visent à améliorer la gestion des données et en particulier, celles que l'on rencontre dans les domaines techniques liés aux thématiques de l'ENSMA (aéronautique, transport, mécanique et énergie). La démarche suivie consiste à utiliser des modèles de connaissance appelés ontologies (ou dictionnaires dans les domaines techniques) qui fournissent une description consensuelle et formelle des concepts d'un domaine d'étude. Ces travaux s'appuient sur des ontologies normalisées et définies avec le modèle PLIB (normde ISO 13584) qui est spécialisé dans la description des données techniques. Cependant, les ontologies étant également fortement utilisées dans le contexte du Web Sémantique, mes travaux s'intéressent également aux modèles et langages développés dans ce contexte (RDF, RDF-Schema, OWL, SPARQL).

Contributions

Pendant ma thèse, j'ai développé un langage nommé OntoQL qui permet d'exploiter des données décrites par des ontologies stockées dans des bases de données spécialisées. Les particularités de ce langage par rapport au langage du Web Sémantique (notamment SPARQL) sont : (1) d'être basé sur un noyau commun aux différents modèles d’ontologies qui peut être étendu par des instructions de ce langage (2) d'exploiter la couche linguistique qui peut être associée à une ontologie conceptuelle pour permettre d’exprimer des instructions dans différentes langues naturelles (3) de rester compatible avec le langage SQL. Ce langage et la plateforme logicielle associée (disponibles sur la Forge du LIAS) ont été et sont utilisés dans plusieurs thèses (L. Mastella, N. Belaïd, D. Tapucu, H.V. Téguiak, Y., etc.), projets académiques (ANR EWok-Hub, DAFOE 4APP) et applications industrielles (Institut Français du Pétrole, EDF, Compagnie Française de Câblage, Geosiris, CRITT Informatique).
Depuis ma thèse je poursuis mes travaux sur les bases de données sémantiques et les langages de requêtes associés selon deux axes (1) étendre les fonctionnalités et domaines d'application de ces langages et (2) optimiser les traitements associés lorsqu'ils sont réalisés sur une ou plusieurs bases de données.
