The Semantic Web extends today's Web technology by enabling machine-human as well as machine-machine interactions with well­ defined semantics of Web resources and services. Automated interoperation among machines demands a tool which can manipulate semantic information, enhances understanding and reasoning, and leads to machine-machine collaboration. This Intelligent Web Service (lWS) System presents a declarative approach to the construction of Semantic Web applications by means of a unified modeling language XML Declarative Description (XDD) and an XML-based declarative programming language XML Equivalent Transformation (XET). With XDD's expressiveness and inference capabilities as well as XET's computational, document- and query-processing mechanisms, IWS introduces a uniform representation of ontology axioms, ontology definitions and instances as well as application constraints and rules in machine-processible form. It is also employed to create a prototype of B2B travel businesses as a demonstration of the framework's practicality and potential usage on the Semantic Web.
