In the online social network, seeking the trustworthy agent is a very difficult task. One of the solutions is to design a valid trust management mechanism. After analyzing the current trust model, we find out that current trust model can only be applied to static network analysis. In this paper, we define a series of trust sense factors such as the user's sojourn-time ratio, the user's subjective evaluation of the website, the ratio of taking a website as favorite website, the degree of the completeness of transactions. In such way, a new trust model is established to collect the data of the user, which is more suitable for dynamic network analysis. In this model, reasoning is made with the fuzzy sets theory, and user's trust in the website is reflected in terms of percentage. The system is able to keep abreast of the user's trust trends promptly and comprehensively, and provide users with references for searching the trustworthy agent.
