摘　　要：提出了由交互经验计算用户态度,以及利用交互时间序列计算用户行为模式变化的方法。进而利用态度、交互经验、行为模式3种信息综合建立新的信任评估模型。实验证明该模型能够适应社交网络的动态性及复杂性,并可有效量化3种信息对信任的影响,从而提高社交网络中直接信任评估模型的可用性与准确性。A method was proposed to evaluate the user＇s attitude from the interaction experience and deduce the user＇s behavior pattern by employing the interactive time series.Further,a new trust evaluation model was constructed by considering the following features：the user＇s attitude,the interaction experience and the behavior pattern.The experiment results show that the presented model can be adapted to dynamic and complex social networks,and can efficiently quantify the influence on the trust of three kinds of information,and enhance the availability and accuracy of direct trust evaluation model in social networks.
