Génération de documents virtuels par intégration de relations entre documents structurés pour la recherche d'information

Abstract : Information retrieval on structured documents attempts to answer in a precise way to a user request by providing only elements of documents (doxels) that satis es this need for information. This thesis investigates the characterization of relations (structural and non-structural) between parts of structured documents in this context. We model structured documents indexing using the structure and relations between doxels and we characterize these relations by relative exhaustivity and speci city values. The querying process based on these structured documents generates virtual documents as results, indicating the relevant links between doxels. The model is validated through the evaluation campaign INEX 2007 data (660 000 documents Wikipedia, 100 requests) and the results show an improvement of 24% in average precision with the vector space model.
