 Research

 Research topics

My research interests mainly fall in the area of Information Retrieval. I'm currently working on the following subjects:

  • 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
  • Contextual Information Retrieval
  • Information retrieval in data streams


In the past, I also worked on

  • Evaluation of Information retrieval: protocol, metrics, etc. (Quaero project)
  • Information retrieval on semi-structured documents (like XML documents).

This research was supported by the XFIRM system, which has been developed during my PhD thesis. I was mainly interested in:

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

I also participated to works about multimedia retrieval and relevance feedback in XML documents.
