In this paper, we show that using semantic information describing users and resources can reduce the problems and lead to a better precision, coverage and quality for the recommendation engine. Semantic web is the infrastructure used for managing such semantic descriptions. We have evaluated several strategies of filtering hybridization: weighting, adaptive change or switching and feature combination.}, }
