  author={Wang Qian},
This paper improves traditional collaborative filtering algorithm,proposes a new user profile based on concept hierarchy tree,which can make recommender systems still work even when users have no common rating items.In the process of similarity calculation and recommendation formation,it also uses concept hierarchy thought to generate recommendation lists by different categories,avoiding recommendation lack of diversity.Experimental results on MovieLens dataset show that the improved algorithm… CONTINUE READING
