MOD - A Multi-Ontology Discovery System

The rapid development of semantic web services has led to a demand for a semantic web service discovery mechanism. Though such discovery systems have been developed, there is a lack of support for matching semantic web services which use different ontologies. This paper introduces a general framework for the discovery of web services that use both the same ontology as well as different ontologies and describe experiments to test the algorithm. Contributions include a discovery algorithm and a novel concept similarity matching algorithm to eliminate mismatches and to increase the accuracy by using syntactic, properties, domain, and neighborhood similarity matching. The experimental results confirm the viability of the discovery system.
