摘　　要：现有的基于XML的Web服务规范或标准没有提供足够的手段来描述Web服务,以支持发现、组合以及执行Web服务的一般机制。因此,分布的、异构的和动态变化的Web服务的交互会产生很多问题。为了更有效地适应Web服务的分布的、异构的、不断变化的特点,针对现有的SOA架构健壮性不强的问题,提出了基于语义的SOA。通过增加Web服务的语义描述,并以这种具有语义的描述来发布和发现Web服务。从而使这种架构不仅支持功能的匹配,而且还能支持实现最佳质量标准的匹配。The present XML - based specifications and standards of Web services can not be sufficient to annotate Web services, so as to support generic mechanisms for discoverlng, composing and executing Web services. Thus, the interaction of distributed, heterogenous and ever changing Web services can result in several problems. In order to adapt to distributed, heterogenous and ever changing characteristics of Web services in a more effective way, and aimed at the weak adaptability of available SOA,semantic Web services - based SOA is proposed. That is ,Web services are advertised and discovered by augmenting Web services with rich semantic descriptions. As a result, Web services will be discovered not only based on their functional requirements, but also the best quality criteria by this SOA.
