Impact précoce du poids des balises pour la recherche d'information ciblée
Abstract
This paper addresses the integration of XML tags in terms weighting function for focused XML Information Retrieval (IR). Our model allows to consider a certain kind of structural information: tags that represent logical structure (title, section, paragraph, etc.) as well as tags related to formatting (bold, italic, center, etc.). We take into account the tags influence by estimating the probability that tags distinguishe relevant terms. Then, these weights are integrated in terms weighting function. Experiments on a large collection during INEX 2008 XML IR evaluation campaign showed improvements on focused retrieval.
