International Newsmap is an automated geographical news classification system for international communication and journalism research by Kohei Watanabe. The original version of Newsmap was developed in August 2011 after his study at the Department of Political Science at Central European University in Budapest. Since then, Newsmap has been classifying foreign news stories collected from numerous online outlets across the world.
The geographical classifier is trained using a manually compiled geographical lexicon and a corpus of international news stories on Yahoo News. The same algorithm has been used for various social scientific research projects involving large scale media analyses. For the detail of the classifier, refer to a paper.
