基于形式本体的POI数据分类方法

Classification Method of POI Data Based on Formal Ontology Theory

针对现有地理信息分类体系的不足,基于形式本体的原理,结合语义学理论,以深圳市的POI数据为实验数据,通过采用对POI数据形式化语义分析的方法,利用概念的本体属性组来规范表达POI概念的语义,提出一套新的分类体系。分类结果有效地解决了传统分类体系中存在的语义和概念上的异构问题,并成功应用于深圳市公共信息服务平台,从新的视角为其他城市的POI信息分类以及其他类型的地理信息分类提供参考方法。

Setting out from the insufficiency of the existing geographic information classification system,under the principle of formal ontology theory that combined the semantics theory,this paper standardizes the semantic concept of POI through formalized concept analysis of POI data and puts forward a new classification system on the basis of the POI data of Shenzhen as the experimental data.The new classification system solves effectively the problems in current traditional one such as heterogeneous build of semantics and concept,which has been successfully applied to the platform of Shenzhen Geographic Information Public Service.The paper can provide reference for the classification of POI information and other geographic information classification of other cities.
