What is it?

Geograpy3 is a Python library to extract geographic details like:

  • country
  • region
  • city

from plaintext and websites.

Examples

Let's take the BBC New article of May 2011 'London 2012 Olympic torch relay route revealed'. In this article quite a few countries, regions and cities are mentioned. Let's extract that information using geograpy3

Code

import geograpy
url='https://www.bbc.com/news/av/world-africa-54272558'
places = geograpy.get_geoPlace_context(url = url) 
print(places)

Result

countries=['Jersey', 'Guernsey', 'Greece', 'Belarus', 'South Africa', 'Australia', 'New Zealand', 'United Kingdom', 'Ireland', 'United States', 'Canada']
regions=['Newcastle', 'Bristol', 'Oxford', 'Southampton', 'Greek', 'Sheffield', 'Greece', 'Media', 'Land', 'Cornwall', 'June', 'Nottingham', 'London', 'Dublin', 'Belfast', 'Guernsey', 'Locog', 'Olympia', 'Shetland', 'Jersey', 'Cardiff']
cities=['Dublin', 'Newcastle', 'Belfast', 'Sheffield', 'Cardiff', 'Oxford', 'Southampton', 'Nottingham', 'London', 'Bristol', 'Media', 'Olympia', 'Guernsey', 'Cornwall']
other=[]

History

first geograpy (2013)

The name "geograpy" was coined by Chris Albon

Angela Oduor Lungat, Brunobg, Jonathon Morgan, Romina Suarez and other contributors from Ushahidi, Nairobi, Kenya created the first and popular geograpy version. It was forked more than a hundred times and had more than 200 Stars on github.

This version was restricted to python2 and as of 2020-09 there are still some 29 open issues in this project. The project is officially archived and you might want to use geograpy3 instead.

geograpy2 (2014)

The geograpy2 fork was created in 2014. It solves several problems (such as support for utf8, places names with multiple words, confusion over homonyms etc).

Since 2015 the project didn't move forward much so you might want to use geograpy3 instead. https://github.com/Corollarium/geograpy2

geograpy3 (2018)

geograpy3 was forked from geograpy2 in 2018 by Somnath Rakshit. It added python3 compatibility. In 2020 Wolfgang Fahl joined the project since he had a need to use it for the Proceedings Title Parser as part of the ConfIDent project

try it! - you may probably experience a timeout on this query. It takes about 1 min on a local wikidata copy based on blazegraph

If your are intested in the result you can download the Sqlite version of query result and e.g. inspect it with the DB Browser for SQLite
