| 摘 要： | 针对地理信息对语义的特殊要求,提出了利用本体实现基于语义的地理Agent的集成和互操作的基本方法.通过该方法,首先利用地理Agent中的领域本体把各个分布异构的GIS节点用本体封装起来,对外显示基于本体的界面;然后通过Agent的语义推理机制,建立不同本体系统之间的语义关系;最后通过不同GIS节点之间的语义关系投影到全局本体Agent中的本体树实现地理信息系统的集成,从而为紧急状态决策支持系统提供一个基于语义的地理信息服务,实现了透明和准确地访问空间信息资源和服务.

| Abstract: | For meeting the semantic request of the geography information systems,the concept of the ontology-based GeoAgent(geography agent) is defined.Using the GeoAgent,the geography data are encapsulated by geography ontology so that a conceptual interface is exhibited to others Agent.The semantic relations of the GIS nodes are built by logic reasoning.A virtual environment is established after all GIS nodes are integrated into a global ontology by using the semantic relations.An example is given;the example provides a details on how the GeoAgent can transparently and effectively access the information and serve as a semantic tool for decision support system. |
