| Abstract: | Purpose/significance] Aiming at improving the efficiency of friend recommendation algorithm,this paper expands the connecting relations between social network users based on the theory of three-degree influence.Method/process] Firstly, the strength of friend relationships between users could be calculated, which would be used to filter out user set. Secondly, this paper calculates the similarity of interests based on the content of common concern of users. Thirdly, it achieved to recommend friends to social network users by fusing the strength of relationships and the similarity of interests.Result/conclusion] The experiment results on douban data show that the proposed method is a better recommendation method. It can be helpful for the friend recommendation and complements the theory of social recommendation. |
