基于空间语义的地理编码在智慧城市信息系统中的应用

Application of Geocoding Based on Spatial Semantic to Smart City Information System

近年来智慧城市发展迅速,各级政府和相关企事业单位都建立了以空间信息为核心的信息管理系统,空间信息大部分利用地址描述。地址在系统数据库中以字符串形式存在,由于语言习惯和文化差异,地址描述普遍不符合数据规范化要求,甚至有些地址中出现了逻辑错误,难以在智慧城市信息系统中直接应用。通过分析地址要素的层级关系,提出了一种基于空间语义的中文地理编码方法,研究了空间语义地址模型,设计了基于分层级地址树模型的地址标准化过程。结合智慧街道实际应用,对比模糊匹配方法,实验结果表明,该方法具有较高的地址匹配率。

In recent years,Smart City are developing rapidly.Information management systems centered on spatial informationhave been established in governments at all levels and related enterprises.Most of the spatial information is describedwith address.Due to language habits and cultural differences,the addresses storedas strings in the system databasedo not meet the requirements of data standardization.With the logicalerrors in the addresses,it is difficult to be applied directly to the smart city information system.The method of Chinese geocoding based on spatial semantics is proposed through the analyses of the hierarchical relationship of address elements.Then the model of spatial semantic address is studied and the process of address standardization based on the model of hierarchical address tree is designed.Ascompared with the method of fuzzy matching with an example of Smart Street,the method of Chinese geocoding based on spatial semantics is more effective.
