Distributed Service Composition and Execution Framework in GloServ

We describe a framework for a distributed ontology based dynamic composition and execution of services. This paper describes an extension to GloServ, an ontology-based global service discovery system, which performs service composition with services described in OWL-S. It also analyzes the bottlenecks in using OWL-S for service composition and gives detailed results on the different types of ontology descriptions that work best for service composition.
