中文摘要：
结合语义Web技术，设计了制造网格服务本体开发步骤，对制造网格服务进行语义描述，提出了基于OWL-S的制造网格服务发现模型。将本体匹配技术引入制造网格的服务匹配中，并改进了本体匹配中概念相似度算法，为解决服务匹配问题提供一个有益的尝试。实验表明，该语义模糊匹配技术能有效地弥补基于关键词的服务发现查全率和查准率较低的不足，提高服务发现的质量。
英文摘要：
With semantic Web technology, the process of developing MGird services ontology was designed, as well as MGrid service description. A MGird service discovery model based on OWL-S was proposed. The service matching problem was transformed into ontology matching problem here- in, and the algorithm for concept similarity measurement in ontology was improved. Experimental results show that the proposed model and algorithm are prior to the keywords based service discovery method in the aspects of veracity and perfectibility, effectively make up for the lower recall and precision of the kevwords based service discovery and improve the quality of service discovery.
