| Abstract: | 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. |
