语义引导的图标式地理概念建模环境初探

以地理问题求解和地理科学研究环境建设的实际需求为引导,针对当前地理建模过程中存在的建模思想难以交流与重用、建模方式复杂、多领域专家协同建模困难等问题,研究地理概念建模过程中地理概念场景、概念实体及其相互作用关系的表达与元数据描述方法,利用空间数据表达规范与地理模型元数据表达规范逐步引导数据与模型的选择与匹配,构建地理概念模型,并在此基础上提出一种可视化、引导式的面向地理问题表达的概念建模方法,为地理研究提供一个语义引导的图标式地理概念建模环境。

Semantics guided geographic conceptual modeling environment based on icons (Key Laboratory of Virtual Geographic Environment| Nanjing Normal University, Nanjing 210046, China)

There are many problems in conceptual modeling process,such as difficulty of modeling conception sharing,complexity of modeling method,difficulty in cooperative modeling by experts from different domains,and so on.In order to solve those problems,we study the metadata and semantic of geographic conceptual scenarios,geographic conceptual entities and relationships among them.In this paper,geographic conceptual entities are represented by the configurable icons,the relationships among entities are represented...
