摘要：The traditional search of trust, mostly uses the flooding method. This algorithm has low efficiency and high computational cost. It also cannot solve the issue of overlapping of friends-circle. To solve these issues, a new trust search algorithm was proposed. The influence of event weight to node's recommended qualifications was fully considered in the new algorithm by the improvement of subjective logic theory, the path dependence and trust-circle caused by the overlapping of friends-circle were solved effectively by the strategies of dual- threshold screening and set added. The experiments results showed that the complexity of trust network was reduced, the efficiency of trust search was improved, and the accuracy of trust evaluation was increased through the new algorithm.
