A cost-effective algorithm for inferring the trust rate between two individuals in social networks
Chengying Mao (Supervisor), Changfu Xu, and Qiang He
Knowledge-Based Systems, 2019. (IF: 7.2, SCI 1区&Top,CCF C)
In this paper, a restricted traversal method is defined to identify the strong trust paths from the truster and the trustee. Then, these paths are aggregated to predict the trust rate between them. During the traversal on a social network, interest topics, and topology features are comprehensively considered, where weighted interest topics are used to measure the semantic similarity between users.
