Semi-automatically Annotating Data Semantics to Web Services using Ontology Mapping

Abstract

In this paper, we propose an approach to solve the problem of annotation by mapping concepts in data type definitions, namely XSD, in WSDL files to shared ontologies represented in OWL, then using the mapping results to annotate XML schema according to SAWSDL specifications. Thus, we are moving towards to enrich WSDL with semantics without introducing new standards. Furthermore, our semantic annotation establishes a foundation for data mediation, the solution to the problem of data heterogeneity in service composition.
