Abstract

Abstract: The traditional Web services selection algorithms were analyzed and the problems existing in dynamic environment were pointed out. A personalized Web services selection method based on collaborative filtering was proposed to address these problems. And a personalized Web service selection framework was designed, which used the collaborative filtering to predict the Quality of Service (QoS) and selected the best service that met users' requirements. About 1.5 million real world QoS data were employed to evaluate the proposal with other four methods and the experimental results demonstrate that the proposed method is a feasible manner and it provides better prediction results.

Key words: Web service, service selection, collaborative filtering, Quality of Service (QoS), similarity

摘要： 对传统的Web服务选择算法进行分析，并指出其在动态环境下存在的问题。为了解决该问题，提出了基于协同过滤算法的个性化Web服务选择方法，并设计了一个动态的Web服务选择架构，架构使用协同过滤算法对Web服务的服务质量(QoS)值进行预测并选择最优的Web服务以满足用户的需求。使用150万条真实Web服务的QoS数据与其他4类算法进行了对比实验，结果表明所提方法的可行性和准确性。
