基于可信相似用户的服务推荐方法
Service Recommendation Method Based on Trusted Similar User
摘要
Abstract
It is increasingly important to perform service recommendation as increasingly more users and services are involved in service computing,but some inauthentic service evaluations from a few users decrease the dependability and effectiveness of service recommendation.This paper proposes a service recommendation method based on trusted similar users.Suspicious evaluations are dug out from the history of the user evaluations,which are used for computing the degree of user reliability and subsequently removing the unreliable users.The neighbor sets of each trusted user are determined by computing the user similarity.According to the preference of any user,candidate services from neighbors are carefully overall evaluated and effectively recommended.Experimental results show that the method,in the case of rejecting a malicious user,recommends more reliable service and effectively improves the quality of recommendation.关键词
