摘要/Abstract

摘要：

Abstract: By introducing the concept of attribute similarity, an attribute matching mechanism is designed. Also the recommendatory methods to calculate the similarity degree
are given.The power-law distribution of deal times isrecovered through analyzing the actual deal data set from Epinions in which there is 49，290 users 139 .738
products，664,824 comments and 487，181 trust relations. Based on attribute matching mechanism a feasible brim
and-buy scheme called preferred buy mechanism(PBM) in E-commerce is proposed. Simulations show that the
presented mechanism can better imitate deal pattern in practical E-commerce system,and can produce a web of trust
with the similar rules to the real data.The PBM is better than the existing approach(e. g.，best rating).
