Une Nouvelle Approche d'Expansion Sociale de Requêtes dans le Web 2.0
01 January 2011
In this paper we address the problem of queries expansion and its personalization which consists of enriching user queries with additional information to maximize her satisfaction according to, e.g., her interests and her social ecosystem. While focusing on tagging systems, the proposed approach considers (i) the semantic similarity between tags composing a query, (ii) a social proximity between the query and the user profile for personalized expansion, and (iii) on the fly, a strategy for expanding user queries. The proposed approach has been evaluated using a large dataset crawled from del.icio.us and compared to the closest related work and the results show a clear superiority of our approach and promising results.
