Learning to rank, a task applying machine learning techniques to rank the expected information of the users, such as movie items users might be interested in. It is useful for collaborative filtering, which is regarded as a hot subfield of computer supported collaborative work(CSCW). In this paper, we propose an algorithm based on RankBoost to rank expected information of the users more accurately...
