Abstract:

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 herein, 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 keywords based service discovery and improve the quality of service discovery.
