面向全国经济普查需求的专家系统地理编码方法

Expert system-based geocoding method for national economic census application

分析了国内外地理编码技术的研究和使用现状,结合我国经济普查项目中地理编码的实际需求,借鉴专家系统的相关概念和方法,提出了一种基于专家系统的地理编码方法。该方法充分利用行业系统中已有的中文地址与空间要素间的对应关系,挖掘与之匹配的地址特征。对于需要定位的模糊地址,该方法首先将模糊地址拆分为若干地址要素,再在要素地址特征库中进行匹配,从而实现该模糊地址的空间定位。该方法能有效地提高模糊地址的定位成功率。

After analyzing those domestic and international geocoding methods,this paper proposed an expert system-based geocoding method for national economic census application. This method mined some address characters of every spatial feature based on their corresponding relationships,which had been existed in national economic census spatial database. To a certain vague address to be geocoding,this method would separate it into several address elements,and then located it by analyzing the comparability between those elements of the vague address and the address characters of every spatial feature. This method could promote the locating rate of the vague addresses.
