A Unified Analysis of the Evidential Trust Evaluation Techniques

It is crucial for the participants over the Internet to evaluate each other´s trustworthiness before initiating any commercial transaction. In this paper we further extend our previous work novel evidential trust evaluation algorithm (NETEA) [1] for Dempster-Shafer theory and subjective logic for computing recommendation trust under same environment. We identify limitations for each and propose some extensions to Dempster-Shafer theory for reliable trust evaluation using some new decision fusion techniques.
