Research On TAR Architecture Of Cooperative Data Management Based On Ontology

This paper presents the framework of cooperative data management software based on researchand development of seller-oriented logistics management platform of e-commerce company.Thesoftware architecture,optimized by Agent-Oriented technology and ontology mapping method,implements by SOA/Web Service techonoloy,Mediator/Wrapper data integration framework andAgent-oriented technology.Workflow technology and Multi-Agent collaboration are used to achievecollaborative data access, ontology and mapping technology are to realize collaborative data storage.Firstly,some important technology of TAR-oriented data cooperating are discussed,including SOAarchitecture and Web Service technology for establishing the sofeware model,Agent-orientedtechnology for class model optimization,extended KQML communicate method for Multi-Agentcooperation,workflow model method and role-oriented cooperative technology for the taskscheduling,Mediator/Wrapper framework for the share of data,OWL description templates are used toestablish the ontology tree,including global ontology and local ontology,and the ontology mapping isused to resolve the semantic heterogeneity.query process is to realize transparent access to data.Next, the requirements analysis and design procedure of software model are presented.Thesofeware functional model based on application background is set up.and at the stage of the functionalmodel,the use case diagram and activity diagram are built.and then the global ontology and the localontology are established based on OWL description template,in order to establish contacts betweenthem,a mapping discovery algorithm based on the compositive concept similiarity computation andquery transformation algorithm are proposed.The structure and behavior model are constructed byObject-Oriented methods in design phase. the Agent technology is to optimize the software architecture.Finally, the toolkit and technique of software implementation is presented. The major componentsare presented and are described by ACME. Later on, the program implementation for the typicalapplication in the system is presented.The design and implementation of Agent-Oriented Optimization Method, Mediator/Wrapperframework and a mapping discovery algorithm, which are applied in the TAR Architecture ofCooperative Data Management, have theoretical significance and engineering practical value.
