介绍了一种基于本体论的交通异构数据集成系统和技术核心--本体的构建方法.该系统通过全局本体和局部本体的映射实现系统数据的语义解释,使得异构数据库对于应用层而言是透明的.该方法降低了开发难度,提高了开发效率,增强了系统的可维护性和可扩展性.
介紹瞭一種基于本體論的交通異構數據集成繫統和技術覈心--本體的構建方法.該繫統通過全跼本體和跼部本體的映射實現繫統數據的語義解釋,使得異構數據庫對于應用層而言是透明的.該方法降低瞭開髮難度,提高瞭開髮效率,增彊瞭繫統的可維護性和可擴展性.

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.
