Abstract

Facing a vast number of grid services in grid environment, how to find the best and satisfying services is a challenging issue. In this paper, we first propose a template to describe the grid service fully and extend the WSDL specification. In order to match the best satisfying services we present the accuracy degree function of service matching based on ontology to match the service in three-step. Next we apply this services matching solution to the actual model and make services type and QoS matching on different layers. Experiments prove that this grid services matching model has better matching accuracy degree and high efficiency over other models
