چکیده مقاله
Trust network in social networks can be considered as graph which trustors and trustees are graph vertices and edges present trust between them with measured values To evaluate trust between trustors and trustee there is some similarity measures to measure similiraty between trustors together or trustees together and then by using evaluated values predict trust value between them Similarity measure has important effect on final accuracy In this paper we propose graph based similarity measure Similarity between to users is computed by connection between them on graph then this computed similarity used with k nearest neighbor method to evaluate predict trust between users To the best of our knowledge this is the first work introduces graph based similarity measure, emprical results on two real datasets show accuracy of predicted trust using proposed similarity measure outperformes accuracy of method without it
