Traffic Heterogeneous Data Integrating System Based on Ontology
基于本体论的交通异构数据集成系统

This paper develops a traffic heterogeneous data integration system based on ontology. Its key technology is ontology construction. This system is able to provide the semantic explanation of systematic data by means of mapping from global ontology to partial ontology, so that heterogeneous database is transparent for the application layer. The proposed method reduces developing difficulty, improves developing efficiency, and enhances the maintainability and expandability of the system.
