Nipping at the heels of yesterday's story about the software  that automatically writes news articles comes another technological  innovation changing the shape of journalism: software that reads news  articles. 
 Kalev Leetaru of the University of Illinois determined that using the Nautilus SGI supercomputer to analyze news stories  can help predict major world events. 
The analysis he used for the  experiment was retrospective, feeding the computer millions of articles  from which it was able to determine a deteriorating national sentiment  towards Libya and Egypt before the revolutions in those countries. 
The  system was also able to narrow down Osama Bin Laden's location to within  125 miles before he was found and killed last May.
 More than 100 million articles were gathered for this study, from  various sources including the New York Times archive, Open Source Center  and BBC Monitoring (two organizations that monitor local media output  worldwide). 
The system searched for two primary things in the articles:  mood and location. Words such as “nice” or “horrible” were used to  measure mood, and geocoding converted mentions of places such as “Cairo”  or “Pakistan” to plottable coordinates.
For countries that experienced the “Arab Spring,” the supercomputer  produced graphs that showed a noticeable decline in media sentiment both  within each country and without. Before President Mubarak's  resignation, the tone of media coverage of Egypt fell to one of its  lowest points in 30 years, predicting something that U.S. government  could not. 
As Leetaru told BBC news, the president's continued support  of Mubarak showed that high-level analysis suggested Mubarak wasn't  going anywhere. The graph, however, suggests otherwise.
Leetaru's next step is developing technology to allow this system to  forecast major world events, rather than just analyzing them after the  fact. He compares it to economic forecasting algorithms, as well as  meteorology, in that none of those systems (including his) are perfect,  but using them is far better than just guessing.
