Towards semantics-based resource discovery for the grid

Abstract

We present our experience and evaluation of some of the state-of-the-art software tools and algorithms available for building a system for Grid service provision and discovery using agents, ontologies and semantic markups. We believe that semantic information will be used in every large-scale Grid resource discovery, and the Grid should capitalize on existing research and development in the area. We built a prototype of an agent-based system for resource provision and selection that allows locating services that semantically match the client requirements. Services are described using the Web service ontology (OWL-S). We present our prototype built on the JADE agent framework and an off-the-shelf OWL-S toolkit. We also present preliminary evaluation results, which in particular indicate a need for an incremental classification algorithm supporting incremental extension of a knowledge base with many unrelated or weakly-related ontologies. © 2007 Springer Science+Business Media, LLC.
