Adding Semantics to Attribute-Based Discovery of Web Services

摘要

Publishing and querying for businesses and services using UDDI is limited since UDDI information model supports coarse-grained business and service descriptions, and search capability is by matching of attribute names and values. In this paper we present an enhancement to publishing and querying of Web Services by using more refined attribute templates and a group of mediators that can transform service advertisements and queries from such templates into ontology-based service specifications and queries. By using ontology, Web Services discovery can take advantages of ontological inference, and hence queries can be based on semantics of business and service attributes, and not just the values of those attributes. Web Services discovery in this approach becomes more semantics-oriented.
