Abstract :
Trust modeling is currently a key part in building P2P and other internet-based systems. One way for trust generation is to view the trust among users as a web of trust in large scale internet settings, and the trust quantities are further computed from such a web. However, due to the large size and sparseness of the web of trust, how to effectively represent and propagate trust in such a web remains a challenging problem. In this paper, we first present a novel way for similarity measurement from the point of view of user feedback patterns, which can be further incorporated into a trust model. And then the efficiency and effectiveness of the proposed method is given in simulations.
