摘　　要：对于不同区域、类别的地名地址文本数据,各互联网地图平台提供的在线地理编码与地名检索服务质量参差不齐,用户无法快捷获取地名地址空间化最优结果。该文提出一种基于国内3种主流地图平台的多源在线地理编码与地名检索服务聚合方法,包括数据预处理、最小行政区划提取、地理编码与地名检索服务定位结果获取、最优定位结果选取等内容。以四川省3个地区4类兴趣点作为样本数据,设计了16种地名地址空间化实验,从匹配率、定位精度两方面比较分析各实验结果优劣。结果表明,该文方法显著提升了地名地址空间化质量,具有普适性;相对于单平台地理编码服务,精确匹配率增加了14%~61%,定位精度≤50 m的比例增加了15%~43%;定位质量提升幅度与实验数据地址质量呈负相关。For toponymic address data of different regions and categories,the quality of online geocoding and toponymic POI search services provided by various Internet map platforms is uneven,which results in that users cannot get the optimal positioning results of toponymic address quickly.This paper proposes a method for aggregating multi-source online geocoding and toponymic POI search services based on three mainstream map platforms in China,including data preprocessing,extraction of minimum administrative divisions,acquisition of positioning results for geocoding and toponymic POI search services,selection of optimal positioning results,etc.Taking four types of points of interest in three regions of Sichuan Province as experimental data,sixteen spatialization experiments were designed,and the experimental results were analyzed from matching rate and positioning accuracy.The conclusions were drawn as follows:1)the proposed method significantly improves the positioning quality of toponymic address and it is universal;2)compared with the single-platform geocoding service,the exact matching rate is increased by 14%~61%,and the proportion of positioning accuracy(≤50 m)is increased by 15%~43%;3)the improvement in positioning quality is negatively related to the quality of the address.
