Kalev Leetaru, from the University of Illinois, has performed a study with a supercomputer that takes in sources from Open Source Center and BBC Monitoring, and then scans the articles for mood/tone and location. The data was then put into SGI Altix supercomputer (Nautilus) which made graphs depicting shifts in the mood of a country, or a city, which gave some foresight into what would happen at the time. The study has only applied to past events, but Leetaru hopes to set up a real-time system to help predict major events before they happen.
