A Unified Analysis of the Evidential Trust Evaluation Techniques

摘要

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.
