Ontology_CVGE:本体支持下的协同虚拟地理环境框架

Ontology_CVGE:The Framework of Collaborative Virtual Geographic Environment Supported by Ontology

为地理问题的群体协同决策提供可视化环境是协同虚拟地理环境的基本目标。协同决策是一个领域知识驱动的过程,而本体是目前用于领域知识表达与相关概念描述的重要工具。因此,在分析知识表达在协同虚拟地理环境中所具有的重要意义基础上,提出协同虚拟地理环境中群体决策的迭代过程模型,并以森林灭火决策为例,构建支撑协同虚拟地理环境的本体知识库。最后,综合上述研究成果设计了本体支持下的协同虚拟地理环境框架—Ontology_CVGE。

Offering a visualized environment for group decision to geographic problem is a fundamental goal of CVGE.The process of collaborative decision is under the driver of field knowledge,and the Ontology is an important tool for the representation of field knowledge.So,At the basis of analysising the great mean of knowledge express in CVGE and present the iteration process model of group decision in CVGE.Taken the forest fire fighting for example,the representation of field knowledge has been studied based ontology to construct the knowledge base.Finally,the frame of CVGE based ontology—Ontology_CVGE has been designed.
