 Research topics

I'm working on the following subjects:

  • Information retrieval on semi-structured documents (like for example XML documents). For this purpose, I use the XFIRM system, which has been developed during my PhD thesis. I'm mainly interested in:

    • the automatic processing of heterogeneous collections
    • the use of graph theory in retrieval (AOC project)

    I'm also participating to works about multimedia retrieval and relevance feedback in XML documents.

    XFIRM Prototype

  • Evaluation of Information retrieval: protocol, metrics, etc. (Quaero project)

  • Aggregated search: the aim is to group information nuggets coming from different sources in order to compose an aggregated result for the user. More precisely, we are interested in:
    • Relational aggregated search: attribute retrieval, relation retrieval, etc.
    • Cross-vertical aggregated search
