Recommended Trust Computation Method Between Individuals in Social Network Site.

Nowadays, recommendation has been one of the most important ways for information sharing and transmitting in social network site (SNS). A recommended trust computation method is addressed to confirm reliabilities of recommendations among users. Firstly, computation methods of trust values are defined as belief and reputation to represent subjective trustable relationship among users and objective creditable view of users in SNS. Then, recommended trust computation method is presented based on the above mentioned two kinds of trusts. Recommended trust computation is divided into three aspects: recommended trust computation with different route composition, recommendation objective coincidence and recommendation optional degree. Further, SNS recommended trust computation framework (SRTCF) is proposed. Finally, an example and examinations are given to explain the efficiency and feasibility of our mechanism.
