- New Graph Based Trust Similarity Measure Saeed Garmsiri Ali Hamzeh Estudios Ambientales Trust graph based trust evaluation similarity measure 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 s there is some similari ty measures to measure similarity between trustors together or trustees together and then by using evaluated values predict trust value between them. Similarit y measure has important effect on final accuracy. In this paper we propose graph based similarity measure. Similarity between t w o users is computed by connection between them on graph then this computed similarity used with k - nearest neighbor s method to evaluate(predict) trust between users. To the best of our knowledge this is the first work introdu ces graph based similarity measure, empirical results on two real datasets show accuracy of predicted trust using proposed similarity measure outperforms accuracy of method without it. 2015 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467547683044 en http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.6-2 Vol.37
