Abstract

Concerning the problem that data sparsity and user preferences quickly change for traditional news recommendation, this paper proposed a hybrid news recommendation algorithm combining social relations and tag information. Firstly, the algorithm utilized the social relationship and hashtag information in the user′s social network. Then it applied the LDA topic model to model user interest. Finally, the algorithm used a hybrid recommendation algorithm based on content and collaborative filtering to complete news recommendations. In the experiments, comparing with existing recommendation algorithms, the proposed algorithm can improve the precision by 10.7%, MRR by 4.1%, NDCG by 10%. The proposed algorithm can improve the accuracy and the quality of news recommendation algorithm effectively.
