While studying language diversity in London, a heat map of languages used during last summer, reveals the top 10 languages used in London’s Twitter sphere. This map was prepared by, Ed Manley and James Cheshire from University College of London. They have used around 3.3 million geolocated tweets, captured in London over the course of this summer. In total, 66 languages were detected. Interesting things to see is the tweets confirmed that certain groups seem to be more dominant in some areas than in others. They have used Chromium Compact Language Detector – a open-source Python library adapted from the Google Chrome algorithm to detect a website’s language.
