Semantic-based Web Service Composition On Model Research And Implementation

Further development of Internet technology and widely available, hasfundamentally changed people’s lives. On the production, distribution, integration andinterpretation is an important transaction people experience. The use of informationalready from the simple to read and absorb into the interaction and expression phase.Because of the complexity of the needs of the Internet gradually increased, the use ofWeb services technology, the reality of expanding the value of existing systems ordesign a new system, the user needs to quickly realize, has become the focus ofattention. Semantic ontology of technology, making Web services to mutualrecognition between the relevant semantic information, through reasoning andalgorithms that can automatically be combined into a number of simple models ofcomplex Web service composition, to meet the complex needs of users, these featuresand advantages of a good theoretical research and practical application.Features for Web services and Web service composition based on semantic modeldifficulties, this article discusses Web services technology, ontology and semanticWeb services, semantic technology combined technology trends, research, andcompared the combination of semantic Web service discovery technology. Ontologyfor the semantic development, Web services description language semantics, semanticreasoning and Web service composition discovery technology features, comparativeanalysis and modeling technology, and proposed framework for ontology-basedsemantic Web services composition to solve the basic ideas and methods. Proposedbased on semantic annotation of Web services automatic discovery and compositionmodel that ontology-based semantic standards to create a model framework, markedby semantic Web services languages, making it rich in semantics, combined with Webservices to facilitate the development, reasoning, discovery technology, to realize thesemantic Web services automatic composition of the target.Automatic semantic annotation of Web service discovery model, the Web serviceinstance, with Web services composition model is proposed to solve process andfunction modules, get Web service composition programs, and through the evaluationcriteria proposed model, the optimal solution for Web portfolio. Web services throughthe case study to verify the semantic annotation of Web services based onauto-discovery and the feasibility and reliability of the combined model.
