摘　　要：用户之间的信任程度是影响用户社交网络行为的重要因素,但目前针对在线社交网络中用户之间信任值及其传递规律的研究较少。为此,对在线社交网络中的用户信任传递进行建模。通过分析用户信任值影响因素量化用户信任值,根据链接网络关系建立信任传递模型,从而给出评价指标。基于微博数据的实验结果表明,该模型能够准确描述好友之间的信任传递,为好友互动和好友建立提供有效预测和推荐。The degree of trust between users is an important factor influencing the behavior of users’social network.However,there are few studies on the trust value between users and its transmission rule in online social network at present.To this end,the user trust transfer in the online social network is modeled.By analyzing the influencing factors of user trust value,the user trust value is quantified,and the trust transfer model is established according to the link network relationship,so the evaluation indexes are given.Experimental results based on Weibo data show that this model can accurately describe trust transmission between friends,providing effective prediction and recommendation for friend interaction and establishment of friends.
