Trust Evaluation based Recommendation Control Model in Social Network Site

Abstract:

For the sake of the security challenge to manage strange recommendations, a trusted recommendation control model (TRCM) for social network sites is established. TRCM describes four parts in social network site(SNS) recommendation formally including roles of individuals, recommendation routes, factors of trust and control rules. This model combines the belief among individuals and reputation to calculate three kinds of the recommended trust such as serial route recommendation, parallel route recommendation and overlapped route recommendation. Further, factors about the objective bias and confidence in TRCM are addressed to evaluate the reliability of the recommended trust computation. Meanwhile, TRCM defines a set of trust control rules to manage the recommendation in SNS. Experiment results verify the efficiency and feasibility of the model.
