一种基于本体的Web语义服务架构的研究

On a Semantic Web Service Architecture Based on Ontology

为解决现有的Web服务缺少形式语义支撑,导致Web服务的自动选择和组合困难的问题,该文提出一种基于本体的语义Web服务架构SOA-2,定义了Web服务本体,并实现QoS和上下文信息在SOAP消息中的嵌入和传递。与已有的方法相比,针对服务选择和组合的智能需求,本文提出的服务本体综合考虑了QoS和上下文因素。

Semantic Web Service is a new subject, which is composed of Semantic Web and Web Service. In order to solve the absence of semantics that causes a central difficulty of automatic Be-lection and combination of Web services, this paper presents a semantic web service architecture SOA-2 based on ontology. In this architecture,a web service ontology is defined,and QoS and context can be embedded and transferred in SOAP messages o Comparing with existing methods,this Web service ontology considers QoS and context synthetically to satisfy the requirements of service selection and comb inaction automatically.
