trust transitivity

It enhanced the rationality of the model. At the same time,4 influencing factors about trust transitivity were dis-cussed,such as cycle path,path length threshold,node honesty threshold and further trust information.
基于交互能力和诚实能力提出了细粒度描述的信任模型,增强了模型的合理性,同时探讨了影响信任传播的4种因素,包括循环路径、路径长度限值、节点诚实限值以及进一步信任信息,并在此基础上设计了基于深度遍历的网格信任传播算法。
