An Ontology System and Semantic Integration Architecture for Intelligent Transportation System of China

摘要

Information is one of the key components in Intelligent Transportation Systems (ITS). Heterogeneity is inevitable because the concerned systems are often developed by autonomous participants.Ontology is a new method describing conception-level architecture and semantic model.In this paper,we study solving the semantic integration of ITS by ontology.Firstly,we bring forward an ontology system for ITS of China,which includes basic ontology,domain ontology and applied ontology.Then we propose the architecture for semantic integration of ITS,which provides with transparent service based on semantic for consumers so that it forms a virtual homogeneous environment for the applications.The research shows that ontology is a good tool to integrate traffic information at semantic level.
