摘要
本文基于矢量数据库模型与地理本体模型之间的形式化对应关系,定义了从矢量数据库到地理本体的映射规则,实现了地理本体的自动构建;在此基础上,通过本体推理规则对地理本体进行推理,使本体中隐性知识显式化,从而实现地理本体的扩展。实验结果表明该方法减少了人工构造本体中出现的错误,提高了本体构建和利用的效率。
Based on the formalized corresponding relationshi Pbetween the geodatabase data model and geo-ontology model, the mapping rules were defined in the paper, through which it realized the automated construction of the geo-ontology; on this basis, the reasoning rules were built to extract the crytic knowledge of＂ the geo-ontology and realize the expansion of it. The result showed that the method could not only reduce the mistakes that are caused by manual work, but also improve the efficiency of geo-ontology building.
