Study on ontology-based integration strategy and methods for PMS

This paper studies the integration methods of PMS (Project Management System) based on ontology theory. An ontology is a collection of key concepts and their inter relationships collectively providing an abstract view of an application domain. It is an essential element in many applications. Paper focuses on the methods of ontology integration for project management system, ontology-based projects heterogeneous database integration and local ontology construction. It builds an interacting architecture of project information based ontology. Moreover, it discusses project integration application service process based on the method of project isomeric database integration, which includes project business process generation part and service discovery and management integration part based on web. And then it gives a structure model of IIIPMO(Isomeric Information Integrated Project Management based on Ontology), which is effective for ontology creation and integration in PM system. Finally, it presents a structure of the ontology-based intelligent decision support system.
