基于本体的多约束服务发现

随着Web服务的广泛应用,服务发现成为服务请求者和服务提供者之间的重要环节,服务发现机制的优劣直接关系到整个服务应用的质量.为了向服务请求者提供高质量的Web服务,提出一种基于本体的多约束服务发现机制,该服务发现机制在语义层面从多个角度选择满足服务请求者需求的最佳服务,从而提供更准确的服务,提高服务的性能;最后实验数据表明基于本体的多约束服务发现机制能在很大程度上提高查准率,进而可以明显地提高服务系统质量.

Multi-constraints Service Discovery Based on Ontology

With the development of Web service,service discovery becomes an important link between the service requestor and service provider,and the quality of service applications is directly affected by the performance of the service discovery mechanism.In order to provide high-quality Web services to the service requester,multi-constraints service mechanism based on ontology was presented,which selects the best service to meet the needs of the service requestor from a semantic perspective with multi-constraints,thus providing a more accurate service and improving the perfor-mance of the service applications.Finally,the experimental results demonstrate that the proposed multi-constraints service mechanism based on ontology effectively improves the accuracy and the quality of service system.
