Abstract：Collaborative filtering is a widely used technique in recommender systems. Extensive studies are carried out on collaborative filtering. However, systematic summary of this field is scarce. In this paper, research of collaborative filtering is reviewed. The meaning and key issues of collaborative filtering, including sparsity, multiple-content and scalability, are described firstly, and then the solutions to the above key issues are introduced in detail. Finally, the future work of collaborative filtering is pointed out. The knowledge framework of collaborative filtering is introduced. It makes the research clues of collaborative filtering clear, provides a reference to other scholars, and improves the performance of personalized information services.

Key words： Personalized Service Recommender System Collaborative Filtering Information Overload
