Introduction of semantic matchmaking to Grid computing

The fundamental problem the Grid research and development community is seeking to solve is how to coordinate distributed resources amongst a dynamic set of individuals and organizations in order to solve a common collaborative goal. The problem of service discovery in a Grid environment arises through the heterogeneity, distribution and sharing of the resources in different virtual organizations. This paper proposes a service discovery framework which is based on semantics. It gives an example of the Grid Job Submission Service written in DAML-S in order to show how service ontologies are implemented. This semantic approach allows a more flexible and dynamic matching mechanism based on semantic descriptions stored in ontologies. (c) 2005 Elsevier Inc. All rights reserved.
