CORMET: A context-aware ontological reputation model for evaluating trust in multi-agent systems

Abstract

Evaluating trust is a context-aware application that several models have been proposed for that in the literature. However, small numbers of these models are context-aware and each of them has its own specific context definition and representation. Due to the role of reputation as one of the main input factors for evaluating trust and lack of a general method for recognition and representation of the notion of context for reputation; we have proposed a context-aware ontological reputation model for evaluating trust in this paper. The proposed model can be used to build special services on a middleware layer which could be applied to different reputation-based trust evaluation models transparently to make them context-aware. Moreover, CORMET enables the interoperation of reputation-based trust models which use different internal context models.
