Abstract :
In this paper, we present a model for grid-based semantic service discovery by combining the expressive power of the present ontology language and the advantages of semantic web techniques. This model is an initial work to support dynamic workflow composition of semantically described services. Our model distinguishes other service discovery models by not only supporting semantic functional matchmaking, but also supporting flexible QoS ranking that differentiates similar services offered by different service providers in grid environments.
