文本地理编码关键技术研究与分析

Research and analysis on key technologies of text geocoding

随着互联网应用的发展,所产生的非结构化文本大多与地理位置相关联,因此,地理信息检索(GIR)成为当前GIS和IR领域研究的热点。文本地理编码是建立文本与地理位置坐标对应关系的过程,是实现GIR的基础。本文对文本地理编码涉及的地理实体识别、地理实体消歧、文本位置聚焦、区域语言建模等关键技术进行分类总结,提出了该领域未来研究工作和面临的挑战,为文本地理编码进一步相关研究提供新思路。

With the development of Internet applications,the resulting unstructured text is mostly associated with geographic location.Therefore,geographic information retrieval( GIR) has become a research hotspot in the field of GIS and IR. Text geocoding is the process of establishing the correspondence between text and geographic coordinates,and it is the basis for implementing GIR. This paper classifies key technologies such as geographic entity recognition,geographic entity disambiguation,text location focus,and regional language modeling involved in text geocoding,and proposes future research work and challenges in this field,and further research on text geocoding,provide new ideas for further related research on text geocoding.
