Abstract: Service scheduling based on semantic is important in service computing, and service scheduling is an optimal process. As the current service scheduling method can not very well considerate the efficiency and the semantic, we researched the way to combine the PSO, ontology and market mechanism, and proposed the method SI3POM to schedule service based on them. hhis method may improve the service scheduling and it provides an efficiency method for users to get the service satisfied. Experiment shows that our method takes full advantage of the capability of PSO, service schedining and resource using arc efficiency also.

Key words: PSO, Ontology, Market mechanism, Similarity measurement, Service
