Abstract:

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.

Key words: geographic information retrieval, geocoding, geographic entity recognition, geographic entity disambiguation, text location focus, language model
