Abstract

Aiming at the problems that the traditional recommendation algorithm ignored the influence of the tight structure of social network structure on user trust transmission and the lack of social psychological explanation, this paper proposed a re-commendation algorithm based on link prediction for directed interaction and user trust. Firstly, it identified the similar user circle of the target user by the integrated similarity between the user preference behavior and the social circle. Secondly, it obtained the directional interaction influence between the target users by combining the node gravity index and the directed influence factor. At last, it integrated user trust value of the directional interaction influence and the user score trust to find a trustworthy similar user set in the similar circle of friends of the target user, which effectively improved the accuracy of the recommendation and finally generated the recommendation. The results show that the proposed method has a significant improvement in performance compared to the previous social network recommendation algorithm.
