摘要
分析了天地图·福建多源兴趣点融合更新存在的问题,在考虑小范围POI名称的特点和作业人员采集习惯的基础上,利用分词技术,提出一种改进的POI重复检测方法,开发重复检测辅助工具。该工具应用于天地图·福建的POI融合更新工作中,有效提高了POI重复检测的准确度和数据更新的效率。
This paper analyzed the problems existing in multi-source POI data fusion, and provided an improved POI duplication detection method using words segmentation technology taking into consideration of factors like operator collection habits and POI name characteristics in a small region. An assistant tool also was developed based on the research and used to Fujian Map World POI data fusion, which effectively improved the accuracy of POI duplication detection and data update efficiency.
