Reputation Bootstrapping for Trust Establishment among Web Services

Reputation systems rely on past information to establish trust among unknown participants. Reputation bootstrapping - that is, assessing the reputations of newly deployed Web services (newcomers) - is a major issue in service-oriented environments because historical information often isn´t present regarding newcomer behaviors. The authors examine different techniques for fairly and accurately bootstrapping newcomers´ reputations in a service-oriented environment. They also present experimental results that evaluate the proposed techniques.
