| 摘 要 |
As the exponential growth of the number of users in academic social networks, it makes it difficult for users to find similar scholars whom users are interested in. Thus, a recommendation method for scholars based on trust and research interests is proposed. Firstly, we calculate the trust between users to measuring the valid relation strength by using the interaction behavior of the user in the social network. Secondly, the three degrees of influence rule is utilized to expand the users’ potential friend set. Thirdly, similarity of research interests among users is calculated by the LDA topic model. Finally, the trust and similarity are integrated as the comprehensive similarity by the weighted mean method to recommend users. The experimental results on datasets of SCHOLAT demonstrate that our method can effectively improve the performance of scholar recommendation in terms of precision and recall. |
