基于信誉的语义Web服务发现

服务发现在语义Web领域是一个挑战性问题.一个关键问题是发现满足用户功能需求的最佳服务.同样重要的是,电子商务应用还要求发现满足QoS需求的最佳服务.由此提出一个基于信誉管理的分布式服务选择框架.它主要有以下特点：用一个结构化的覆盖网络作为分布式服务存储系统来提高系统的有效性和可扩展性; 提出一个QoS感知的语义Web服务发现方法,并给出基于用户反馈的分布式信誉度评估算法.最后用一个例子示范算法如何解决实际问题.

Reputation-based Semantic Web Service Discovery

Service discovery is a challenging problem in the Semantic Web service area.One key issue is to discover the most relevant services meeting the functional requirements of users.Equally important,e-Business applications also would like to discover services which best meet their requirements in terms of QoS.In this paper,we present a framework to facilitate Reputation-based service selection,which has three key features.First,we use a structured overlay network as the decentralized service repository system.Second,we propose an adaptive QoS-aware service discovery approach.Then,we present a service oriented distributed reputation assessment algorithm as a QoS support module in our framework.We test our approach on a simple,yet realistic example,and the preliminary results demonstrate that our implementation provides a practical solution.
