摘要
快速、准确地发现满足用户需求的Web服务是目前Web服务发现的一个研究重点。文中提出了一个基于服务质量的语义Web服务发现框架。首先采用遗传算法来实现服务的聚类预处理,以此来降低服务的查找空间,提高服务的查询效率。进一步,针对服务请求者对服务质量的需求,实现了基于WSMO-QoS的服务匹配策略。最后,实验结果表明了所提方法的有效性。
The discovery of suitable Web services for a given user requirement is one of the key technology. A mechanism is proposed to support QoS -based semantic Web service discovery. Firstly to reduce the overhead and enhance the discovery efficiency, genetic algorithm is adopted as a method of service clustering. Furthermore, the service matchmaker based on WSMO - QoS was realized to satisfy the user＇s QoS requirements. In the end,simulation results demonstrated the effectiveness of the proposed method.
