Dynamic Composition of Web Service Based Upon Mediator in Intelligent Logistics Information Application
Dao Chen, Jin Zhang, Qi Zeng · Logistics · 2009
As the demand on information services of the third-party logistics companies become more and more complicated and diversified, a set of information system or a series of relevant Web services is insufficient to serve dynamic and flexible information requirements. The paper applies a brand-new framework of non-backtrace backward chaining Web services dynamic composition based upon Mediator. Under this framework, a rule modeling method in composition and a parameter-level ontology library for eliminating composition semantic conflicts having been set up, and then a non-backtrace backward chaining algorithm is used to dynamically compose Web services. Through the composition technology employed in logistics information application, it will generate the integration plan that intelligently integrates logistics resources and information from the existing Web services, and provide more real-time, effective, flexible information resources for the third-party logistics.
