Research Activities

Leader of the IRIS team at IRIT


My research activities in the IRIS team are related to:
  • Contextual information retrieval. Numerous features related to the context in which a search is performed influence the user's perception regarding the relevance of the returned results.

    More precisely, I am interested in :
    • Information retrieval on streaming data. It relates to issues on highly dynamic and variable data.
    • Exploitation of geographic information. This research focuses on exploiting spatial and temporal dimensions in addition to topical dimension of information in texts
    • Semantic information retrieval. This research intends to capitalize domain representations related to information (i.e ontologies, concept hierarchies...)
    • Structured information retrieval. This work deals with considering document structure in the IR process especially for XML documents.
    • Collaborative information retrieval. This research intends to propose solutions to improve information retrieval via collaboration between users.
    • Personalized information retrieval. This work deals with the modeling of users's preferences and users' needs and their exploitation to improve informaiton retrieval.
  • Data exploration. This research intends to propose models, methods, and tools for analysing peculiar datasets (e.g., bibliographic databases) or data from the Web.
    • la Bibliometrics and Scientometrics. This research is interested in analyzing data on academia to shed some light on how research, researchers, and publication are organized.
    • Multigranular OLAP. This work to propose OLAP extentions for analzing data from various granularity levels.

The contributions related to these research activities comprise :
  • several national and international publications
  • participations to national and european projects
  • prototypes (IR Systems, Assistant for query formulation...)
  • participations to international evaluation programs (TREC, INEX...) or experimentations using reference collections
