Abstract
ABSTRACT We present SATYA, a system that computes a reputation value for Web service providers in order to enhance the service discovery and selection process increasing reliability in SOA transactions. In this work, objective values of service evaluations supplied by monitoring entities are used along with subjective evaluations supplied by service consumers. The objective and subjective values are compared in order to: (i) validate subjective evaluations; (ii) minimize the degree of subjectivity of computed reputation values; and (iii) discover consumers' preferences in terms of QoS metrics. By assigning Web services a trustable reputation value, SATYA enhances the service descriptions provided by registries with additional information to be used during the service discovery phase.
