“…We extend our previous work [23] by taking into account unmatched words, which we believe have the potential to provide useful information to determine the exact context of a query more accurately as well as fill in the parameter values needed to invoke an operation. We propose a Transformation Function T F for each unmatched word in the user query to achieve this objective.…”

“…We provide a brief overview of our previous work in this section. Performance evaluation and detailed description can be found in our other publications [23,24]. There are 3 steps in the matchmaking process -(i) Ontology Matchmaking, (ii) Dictionary Matchmaking and (iii) Fallback Mechanism.…”

“…In this paper we significantly extend our previous work that was focused on just simple matching of query keywords with operation names in WSDL files [23,24]. We have enhanced the matchmaking algorithms with new algorithms, incorporated processing of unmatched query words in the matchmaking model, designed and implemented extraction of parameter values from free-form queries, defined a model for determining a ranking score, and quantified the accuracy of our methodologies using precision and recall.…”

Service-oriented architectures (SOA), based onWeb services as the underlying architecture, have the potential to facilitate dynamic evolution of business processes. However, to fully realize the benefit of the SOA vision, it is critical to shield application developers from the complexity of Web services and related XML-based formats. In the currently available toolkits, users often play an informed role in the mapping of XML based specifications, operation names, message structures, and parameter types. The focus of our work is to design and develop an elegant, intuitive, simple, and powerful free-form query based system that allows interaction with Web services, without requiring the end-user to understand the operation names, parameters types, and other XMLbased information in a WSDL document. Our system uses Semantic Web concepts, ontologies, and WordNet in the process of automating Web services matchmaking. In this paper we focus on presenting techniques for matching free-form queries with appropriate Web service operations and extracting parameter values from user queries. We quantify the accuracy of our methodologies in terms of precision and recall.
