PredSimTrust:Calculating Trust based on Predecessors Similarity

摘要：

　　According to the growth of online communities,it has become an undoubted scenario to interact with strangers.In order to have a successful relation,Trust Management(TM) systems use trust metrics to bring security to these kinds of networks.Moreover,there is a strong bond between sociology and trust in networks.In these systems,there exist methods which aggregate trust value of a target using intermediate nodes between source and that node.Some of them use only raw trust values,while others consider just similarity between these nodes.In this paper,we,however,propose PredSimTrust,a trust estimation algorithm which exploits the similarity and,at the same time,trust between source node and predecessors of a target in a network.We examined the proposed approach on a real user community.The results show that our model outperforms other models which based on intermediate nodes.
