Querying Mediated Web Services

M. Sabesan, Tore Risch, Gihan Wikramanayake


Web services provide interfaces to web resources described by WSDL interface definitions. The Web Service MEDiator system (WSMED) enables querying data accessible through web services. WSMED allows web service meta-data to be automatically extracted from any WSDL description. Then views can be created in terms of the imported meta-data and queried using SQL. To enhance query performance, WSMED permits to complement the automatically extracted web service meta-data with semantic enrichments. A WSMED prototype is being evaluated over existing web services to verify the effectiveness of the approach. It is being investigated how semantic enrichments and other query optimization methods are useful for efficient querying of mediated web services.
