OWL-S is an instance of the Web Ontology Language (OWL) that is used to describe and specify semantic web services. While OWL-S provides a promising mechanism for specification, publication, discovery, integration, and access, the learning curve can be high. Current practices in Web services tend to focus on lightweight specification using automated tools that generate WSDL descriptions. One of the advantages of OWL-S is its flexibility in allowing the creation of many groundings or bindings for a single semantic web service. In this paper, we propose an approach for generating groundings for a semantic web service and demonstrate how the use of lightweight interactive tools facilitates creation of groundings for a semantic web service.
