Abstract

This paper investigates the problem of establishing trust in service-oriented environments. We focus on providing an infrastructure for evaluating the credibility of raters in a reputation-based framework that would enable trust-based Web services interactions. The techniques we develop would aid a service consumer in assigning an appropriate weight to the testimonies of different raters regarding a prospective service provider. The experimental analysis show that the proposed techniques successfully dilute the effects of malicious ratings.
