XPDL Intelligent Data Service Chain based on Ontology

摘要：

At present, in the field of earth science applications there is a difficult problem that how data sharing system to build data services and applications chains automatically, especially in geological data application. It involves the choice of data provider services, data selection, service composition and its interface matching issues. The traditional workflow depends on the strict syntax matching and workflow engine. It is hard for application users to select services and especial needed data provided by selected data service, to comprehend the service function interfaces and make proper service orders, etc. This paper presents a way by using spatial information ontology and rules database to generate data service chain and correspond prototype which achieve a variety of services, matching and composition.
