Impact of Contextual Information for Hypertext Documents Retrieval

Abstract. Because the notion of context is multi-disciplinary [17], it encompasses lots of issues in Information Retrieval. In this paper, we define the context as the information surrounding one document that is conveyed via the hypertext links. We propose different measures depending on the information chosen to enrich a current document, in order to assess the impact of the contextual information on hypertext documents. Experiments were made over the TREC-9 collections and significant improvement of the precision shows the importance of taking account of the contextual information.
