Abstract

Abstract:

Trust network is a social network and is constructed by trust relationships between agents. Different contributions devoted by two dimensions of trust are analyzed, and definitions of service trust and recommendation trust are given. The social characteristics of the trust network is studied and a trust prediction method based on agent’s role-based trust and reputation is proposed. The influences of interactions number, time, reputation, service trust and recommendation trust are comprehensively considered which concord with the cognitive semantics of trust computing and propagation in trust network. The experiment verifies the differences of the role-based trust values and the effectiveness of trust prediction.

Key words: trust prediction, role-based trust, trust network, trust propagation
