Abstract
With the rapid growth of Web-based social networks, it is necessary to provide a way to compute the trust among neighbors in network. Several works have addressed the problem of modeling the trust and its propagation in a social network. But, in this paper, we'll present a method to infer trust from a social network which does not contain any explicit trust information. Actually, we use a game theoretic approach to compute the trust values beyond links in Blogsphere. We'll show the intuitions behind our methods which will lead to the Nash equilibrium. Experimental results show that Bloggers should not fully trust their neighbors, rather, the average recommended amount of trust is a few more than 50 percents.
