In order to establish network interaction pattern based on trust,trust-based basic interaction patterns were proposed and the fuzzy production rules were designed.The basic interaction patterns were used to describe degree of truth of the interaction event trust and that of the integrated interaction pattern.Furthermore,the searching algorithm and refreshing method for the basic interaction pattern based network interaction pattern were proposed.The searching algorithm for integrated interaction pattern is based on the depth-first search algorithm for stack and heap.The active refreshing for integrated interaction pattern is based on user's requirements,while the passive refreshing for integrated interaction pattern is based on trust changes between the interacted entities and the interaction event changes.Theoretical analysis and experiment results show that the method can establish trusted integrated interaction patterns quickly and refresh degree of truth of the integrated interaction patterns.
