OWL-S Ontology Framework Extension for Dynamic Web Service Composition
نویسندگان
چکیده
Composing existing web services for enterprise applications may enable higher level of reuse. However the composition processes are mostly static and lack of support for runtime redesign. In this paper, we describe our approach to the extension of the OWL-S ontology framework for dynamic web service composition. We raise the level of abstraction and propose an abstract service layer so that web services can be composed at the abstract service level instead of the concrete level. Each abstract service is attached with an instance pool including all instances of the abstract service to facilitate fail-over and dynamic compositions.

Using Agent to Coordinate Web Services
Traditionally, agent and web service are two separate research areas. We figure that, through agent communication, agent is suitable to coordinate web services. However, there exist agent communication problems due to the lack of uniform, crossplatform vocabulary. Fortunately, ontology defines a vocabulary. We thus propose a new agent communication layer and present the web ontology language (O...
متن کاملSemantic Web Service Composition
Flexible and dynamic interoperation of autonomous information systems often requires automated or semiautomated combination of several highly distributed and heterogeneous web services. Web service composition aims to accelerate rapid application development and service reuse as well as to provide access to a variety of complex services. There are several approaches developed for the web servic...

Web service technology establishes a common, vendor-neutral platform for integrating distributed computing applications, in intranets as well as on the Internet at large. Semantic Web Services (SWSs) promise to provide solutions to the challenges associated with automated discovery, dynamic composition, enactment, and other tasks associated with managing and using service-based systems. One of ...

Web Service Discovery can be described using OWL-S. It follows web service discovery model because it has conceptual and trivial semantic web service descriptions using service profile ontology of OWL-S. The Web Service Discovery model uses Web Service matchmaking algorithm which enlarges matching techniques used in Structural Case Based Reasoning, allowing the retrieval of Web services based o...
متن کاملEnhanced Semantic Web Service Discovery Using Machine Learning on Mapped WSMO Services
Web services were traditionally defined using the Web Service Description Language (WSDL) as it was the World Wide Web Consortium’s standard recommendation for web service description. Later on, with the advent of knowledge representation using ontologies, more and more services were designed using ontological models, more specifically the Sematic Mark-up for Web Ontology Language (OWL-S). And ...
