摘要
为减少在具体的服务簇中服务请求与Web服务的匹配次数,提高服务发现的效率,提出一种利用匹配关系图的Web服务发现方法 (RGSD)。利用功能属性的匹配条件,定义服务簇中Web服务的匹配关系,对其进行图形化建模,生成服务簇的匹配关系图。当定位到具体的服务簇进行服务查找时,利用匹配关系图能同时匹配多个满足需求的Web服务,减少服务查找的次数。实验结果表明,该方法在保持较高查准率的同时,有效提高了服务发现的效率。
To improve the efficiency of service discovery by reducing the matching time of requests and Web service in the specific service cluster,the service discovery method based on matching relation graph（RGSD）was put forward.Using matching conditions of functional properties,matching relations of Web service were defined in service clusters,and the matching graphical modeling diagram of service clusters was generated.When discovering a service in a specific service cluster,the matching diagram was used to match multiple Web services at the same time,reducing the number of matching services.The result of simulation indicates the superiority of the proposed method in maintaining high precision and improving the efficiency of service discovery.
