Semantic and rules based upon mediator dynamic web service composition in logistics information application

Automatic Web services composition is currently one of the most hyped and addressed issue in the SOA. By composition, we mean taking advantage of the existing Web services to furnish a new Web service with more powerful functionality. Therefore, the paper describes a semantic dynamic Web service composition framework of modified non-backtrace backward chain composition based on Mediator. A semantic rule modeling method and a parameter-level ontology repository for eliminating semantic conflicts have been set up, and then modified Backward chain algorithm is utilized to dynamically compose Web services. Particularly, we explore dynamic services composition applied to the third-party logistics companies, and assist them to intelligently acquire various and effective information from diversified and distributed network by integrating Web resources.
