一种基于语义消息的Web服务组合方法

Semantic Message Based Web Service Composition Approach

在重用现有Web服务的基础上,通过服务组合形成新的、功能增值的服务是语义Web服务领域的一个重要研究内容.本文在Web服务语义描述框架的基础上,提出一种基于语义消息的Web服务组合方法,该方法定义了能够描述不同服务输出、输入消息之间对应关系的语义消息,能够业务逻辑上紧密关联的Web服务有机的组合在一起,从而为Web服务组合者以及面向服务的应用开发人员提供一种简单、直观的组合方法.

One of most important issues in Semantic Web Service is to provide a simple and non-programming service composition mechanism based on Semantic Web Service description.In this paper,We present a semantic message based Web Service Composition study of semantic connection of Web Service and proposes a message-transaction-based approach for SWS.By defining the semantic message and its processing rules,the approach uses the semantic connection between the input and output messages of different Web Services to describe the message exchanges between them.Specially,this approach also defines composition structure information table which,on the basis of semantic web service encapsulation,gives the inner structure of the composition services via the message transaction relationship between services to decrease the complexity of SWSC.
