网格环境中基于语义注释的服务发现算法

网格是一种大规模的资源共享技术,它通过资源的分布式协作来加大资源的共享利用率。网格服务发现是使用网格的基础和前提,但目前的网格服务发现在召回率和准确率上均未达到理想水平。针对该问题,提出了服务行为的概念,并且利用语义技术对其进行注释,在此基础上提出一种基于服务行为语义注释的网格服务发现算法。实验结果表明,与传统方法相比,该算法具有更高的准确率和召回率,并能够在一定程度上提高服务的稳定性。

Service Discovery Algorithm Using Semantic Technology in Grid Environment

A grid is a large-scale resource sharing technology, which increases resource utilization by distributed collaboration. Grid service discovery is the basis and prerequisite for using the grid, but grid service discovery in the recall and precision rates can't reach a satisfactory level. I}his paper proposed the concept of service behavior, and used the semantic technology to note it, On this basis, a semantic annotation service behavior based grid service discovery algorithm was proposed. Experiments show that this algorithm is better than the traditional method. It has higher accuracy and recall rate, and stability.
