摘要
近几年来Web服务在各领域的应用越来越广泛,但是作为其重要组成部分的统一描述、发现和集成协议由于其局限性,无法有效地帮助用户选择高质量的服务,不能满足用户的需求。而现有的研究则主要集中在如何建立基于服务质量的Web服务发现模型上,并未考虑对服务进行管理。针对该问题,提出了一种基于自然衰减和用户反馈的信任维护机制,通过该机制可以对已注册服务执行管理操作,并为用户提供选择服务的参考,提高发现系统的有效性和可用性。
With the rapid development of internet technology,Web services are becoming more widespread in the recent years,but the traditional Web services discovery mechanism can not satisfy the requirements of clients due to its limitations.Meanwhile,current researches mainly focus on QoS-based Web services model and computation,but neglect services management.To address the problem,a trusted management mechanism is proposed based on natural attenuation and user feedback,which can eliminate the invalid services and provide reference evidence for the clients to select the best service.Through the mechanism,the usefulness and usability of the Web discovery system can be improved.
