Abstract

Abstract: Services discovery based on the non-functional（QoS） service features has received increasing attention by service-oriented computing research community.In order to overcome QoS characteristics which is difficult to acquire accurately and dynamic changes，in this paper，a services recommendation approach based on past QoS implementation information is proposed.The framework of services recommendation which can record the log easily is presented firstly.Then，a time-weighted matching algorithm is proposed to implementation services recommendation.Experimental results show that the new approach is feasible and effective.

Key words: Web services, Quality of Service（QoS）, services discovery, services recommendation

摘要： 基于服务的非功能（QoS）特性进行服务发现是面向服务计算领域的一个研究热点。为了克服服务QoS难以获取且动态变化的特点，提出一种基于已往QoS执行信息的Web服务推荐方法。首先给出一种可以方便记录QoS执行信息的系统框架；然后描述了基于时间加权的服务推荐的匹配算法；实验结果表明该推荐方法是可行和有效的。
