Role-based Recommendation and Trust Evaluation

In general, in most trust evaluation systems, the evaluation of a target party under investigation relies on the trust ratings from responding peers/parties who have direct interactions with the target party. This involves recommendations and the trust evaluation on recommendations. The evaluation on the recommendations by the recommendation receiver depends on a few factors, which include the roles of the recommender in the domain of the target being recommended, the recognition of these roles by the recommendation receiver, and the recommendation reputation (trust) of the recommender. In this paper, we propose a novel role-based recommendation and trust evaluation framework (RBRTE), which takes the above factors into account.
