【摘要】 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。更多还原

【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.更多还原
