geonames-tagger

Inspired by countrytagger

This library finds the names of places in a string of text and tries to associate them with known locations from geonames.org. The goal is to tag a piece (or set) of text with mentioned locations, optionally to refine location names to a more canonized value. As well, the corresponding geoname IDs are returned in a tagging result.

As opposed to the original countrytagger, this library doesn't ship with the data included, so one needs to build it locally and then use it with the GEONAMES_DB env var set.

Install

pip install geonames-tagger

Usage

cli

echo "I am from Berlin, Germany" | geonames-tagger tag

this results in the following json response:

python

from geonames_tagger import tag_location:

text = 'I am in Berlin'
for result in tag_locations(text):
    print(result.name)  # the normalized but original name found in text
    print(result.caption)  # the canonical names as list from GeoNames db
    print(result.ids)  # the GeoName IDs

Building the data

You can re-generate the place database like this:

geonames-tagger build

This will download GeoNames and parse it into the format used by this library.
