Moreover, traditional recommender systems consider only the rating information, resulting in the loss of flexibility. Tagging has recently emerged as a popular way for users to annotate, organize and share resources on the Web. Several research tasks have shown that tags can represent users’ judgments about Web contents quite accurately. In the light of the facts that both the rating activity and tagging activity can reflect users’ opinions, this paper proposes a factor analysis approach called TagRec based on a unified probabilistic matrix factorization by utilizing both users’ tagging information and rating i...
