Trust-Contexts Modeling, Organization and Trust Estimation on the Web

Trust-contexts, computational models of the situational factors of trust behaviors, play important roles in trust decisions, but their researches are still in infancy. In this paper, based on earlier studies, trust- contexts are modeled and organized globally on the Web. Then, the basic ideas and an extension of trust estimation, which is the core step of trust decision, are focused. At last, more extensional topics are presented.
