Recently semantic technology have been popular in the spatial information area, but this semantic ability can only support for its own system, cannot fulfils other system's need. So a semantic service middleware taking place of original semantic system, will give a free semantic service without change the system's internal structure.
Services for mobile devices are gradually growing with more orientation towards user-location oriented services. Mobile users nowadays are no longer satisfied with the old frameworks that render static and inappropriate services with regardless to user's location. They require a service that provides intelligent suggestions and results that pertain to their locations, which are also of maximum usefulness...
Web Services Description Language (WSDL) allows a structured way to standardize the description of Web Services, exploiting XML for the exchange of structured information. Nevertheless XML supports little interoperability between services, expected when WSDL documents have to be combined. In this context, the Semantic Web has become a promising research field. Semantic Models (e.g. RDF or OWL) allow...
This paper presents a new approach for automatic Web service composition based on the formalism of Fluent Calculus using semantic Web service descriptions. In our approach, the Web service composition process is viewed as an AI planning problem in the Fluent Calculus formalism. To semantically describe Web services, we have used a Web service domain ontology which is then translated into a Fluent...
Semantic Web service composition is about finding services from a repository that are able to accomplish a specified task. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine. The composer...
The growing amount of distributed data over the internet leads to increasing needs for interoperability. Being able to take into account the meaning of information is a real challenge for suitable data sharing. The semantic web and the ontologies are relevant technologies to provide semantic cooperation of heterogeneous sources. We propose a complete architecture OWSCIS (Ontology and Web Service based...
