基于本体的网络空间决策支持系统研究*

为了不同的空间决策，往往需要建立相应的空间决策支持系统，在这些空间决策支持系统中，大量的空间数据和模型是可以被重复使用的，因此提出了一种基于本体的空间决策支持系统。该系统能够高效、自动地利用互联网中存在的各类异构空间信息与分析资源来支持空间决策；此外，本系统还提出了一种灵活的体系架构来解决空间决策中存在的语义问题。

Research of ontology-based Web spatial decision support system

To build different SDSS (spatial decision support system) to support different geospatial decisions. Among these SDSS, GIS data and models are usually used repeatedly. Thus, this paper proposed a ontology-oriented geospatial decision support system for discovering, efficiently using, and automatically executing GIS data and analysis resource on Internet. By the ontology-based system, it not only presented an ontology-based and Web GIS services-based spatial decision support service, but also provided a flexible architecture to solve geospatial semantic impediments which can be applied to different domain.
