A Trust Evaluation model with Elimination of Uncertain Recommendation

According to the problem of random recommendation for some entities, a Trust Evaluation model with Elimination of Uncertain Recommendation (EURTrust) is presented in this paper. In EURTrust model, entities are classified into two types, certain behaviours and uncertain behaviours, on the basis of recommendation behavior trajectory. Recommendation of those with uncertain behaviours will not be taken into account. Entity trust is determined by the recommended trust and recommend evidence of the recommended entities, and recommended trust reflects the entity recommended history. Analysis and simulation results demonstrate that EURTrust have a good ability of elimination of uncertain recommendation.
