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=[]
Getting the source code
git clone https://github.com/somnathrakshit/geograpy3
cd geograpy3
scripts/install
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
Data used
Adding city details from Wikidata
Query
# get a list of human settlements having a geoName identifier
# to add to geograpy3 library
# see https://github.com/somnathrakshit/geograpy3/issues/15
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wd: <http://www.wikidata.org/entity/>
SELECT ?city ?cityLabel ?cityPop ?geoNameId ?country ?countryLabel ?countryIsoCode ?countryPopulation
WHERE {
# geoName Identifier
?city wdt:P1566 ?geoNameId.
# instance of human settlement https://www.wikidata.org/wiki/Q486972
?city wdt:P31/wdt:P279* wd:Q486972 .
# population of city
OPTIONAL { ?city wdt:P1082 ?cityPop.}
# label of the City
?city rdfs:label ?cityLabel filter (lang(?cityLabel) = "en").
# country this city belongs to
?city wdt:P17 ?country .
# label for the country
?country rdfs:label ?countryLabel filter (lang(?countryLabel) = "en").
# https://www.wikidata.org/wiki/Property:P297 ISO 3166-1 alpha-2 code
?country wdt:P297 ?countryIsoCode.
# population of country
?country wdt:P1082 ?countryPopulation.
OPTIONAL {
?country wdt:P2132 ?countryGdpPerCapita.
}
}
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
CityPops Stats
Here are some statistic queries about the data imported from Wikidata
select count(*) from cityPops where cityPop is not Null
164503
select count(*) from cityPops
453306
select count(distinct geoNameId) from cityPops
414198
select count(*)
from cities c
join cityPops cp on c.geoname_id =cp.geoNameId
