An event-based geo-social user profile for a personalized information retrieval

The user of a social website is often interested by information about events that have interested other users, especially his friends, and that appear remarkably in their researches, exchanges and sharing. In this paper, for a better description of the user and his interests, we propose: (i) a geosocial user profile that takes into account the event aspect of user information needs, (ii) a search process integrating the user profile for a better personalization and adaptation of the search results.
