摘　　要：服务发现和匹配是面向服务计算架构需要解决的核心问题之一,而现有语义web服务发现机制适应范围较窄,匹配效率较低,具有较大提升空间.提出了一种基于服务属性和功能描述的混合服务匹配方法,该方法利用服务本体来扩展服务特征信息,采用LSA方法进行服务相似匹配以提高服务的查全率,再利用本体推理机制来提高服务的查准率.实验证明:此种混合方法能提高服务发现效率.The web service discovery and matching remain to be one of the core problems in Service-Oriented Computing Architectures,while the current available semantic web service discovery mechanism has narrower match scope and lower efficiency,thus it leaves much room for improvement of its performance.This paper proposes an approach for hybrid service matching based on service properties and functional description.The characteristics of services are extended using service ontology;the latent semantic analysis method is adopted for service matching to improve recall ratio;the reasoning mechanism is utilized based on ontology to increase precision ratio.The experiments show that the efficiency of service discovery is improved using proposed hybrid method.
