BBC News: What if a supercomputer could predict world events before they happened? Researcher Kalev Leetaru of the University of Illinois’ Institute for Computing believes they probably can. He recently fed news articles into the “Nautilus” supercomputer at the University of Tennessee. Nautilus analyzed the articles for mood and location and created graphs for the countries that experienced riots during the “Arab Spring.” In every case, the graphs showed a dip in mood before the revolutions began.
Leetaru described the project this way: “I liken it to weather forecasting. It’s never perfect, but we do better than random guessing.”
