Abstract

New Trust, Reputation and Recommendation (TRR) models are continuously proposed. However, the existing models lack shared bases and goals. For this reason, in this work we define an innovative meta model to facilitate the definition and standardization of a generic TRR model. Following the meta model, researchers in the field will be able to define standard models, compare them with other models and reuse parts of them. A standardization is also needed to determine which properties should be present in a TRR model.In accordance with the objectives we were seeking, following our meta model, we have: defined a prestandardized TRR model for e-commerce; identified the fundamental concepts and the main features that contribute to form trust and reputation in that domain; respected the dependence on the context/role of trust and reputation; aggregated only homogeneous trust information; listed and shown how to defend from the main malicious attacks.Trust, Reputation and Recommendation Model; meta model; malicious attacks; context/role sensitivity; main features of trust; homogeneous trust information
