"GeoNLP" is a Japanese research project for developing "geo-tagging" tools and libraries, which can analyze and extract toponyms/location names from natural language sentences (currently only for sentences written in Japanese).
This repository contains codes for the tools and the library to develop C++ applications, PHP extension module, and some test codes.
The GeoNLP project is also providing toponym data sharing service, linked open data service and so on. For more detail, please visit https://geonlp.ex.nii.ac.jp/
