Abstract

Collaborative filtering(CF) recommender systems have been used to provide users with personalized products and services successfully in the past decade. However, sparseness of user-item matrix and the low accuracy are still challenges. To solve these problems, this paper proposed an ensemble framework based on matrix factorization CF for integrating side information of users and items. Based on this framework, this paper proposed a hybrid CF model for integrating COS(coupled object similarity) of attribute information of items. Extensive experiments conducted over large-scale real-word datasets demonstrate that the proposed approach can effectively solve the problem of item similarity measurement. And compared with the traditional approaches, especially in the case of very sparse feature, the accuracy of the recommendation is improved effectively.
