摘要：

在现有服务发现方法中,单一考虑原子服务或服务组合的方式难以满足用户日益增长的需求。针对该问题,设计一个基于模型转换的Web服务匹配框架。在服务发现过程中综合考虑组合Web服务的执行过程信息和服务质量需求信息,为Web服务组合的匹配设计完整的过程:将UML模型转换为过程模型,再将过程模型转换为过程图,最后计算2个Web服务组合的相似度。实验结果表明,该服务匹配框架能够有效区分组合服务,提高服务发现的准确率。

Abstract:

Existing service discovery methods only consider atomic service or service composition,which cannot meet the increasing demands of users.Aiming at this problem,this paper proposes a new Web service matching framework based on model transformation.In the process of service discovery,this framework comprehensively considers the execution process information of composite Web services information and Quality of Service(QoS) requirements.It designs a whole Web service composition matching process:it transforms UML model into process model,then transforms process model into process graph and calculates the similarity of two combined Web services.Experimental result shows that the proposed framework can distinguish the different combined Web services and improve the accuracy of service discovery.

Key words: Web service, service composition, Unified Modeling Language(UML) model, process model, service discovery, service matching
