The Technium: Twitter Predicts the Future
The Social Computing Lab at HP Labs in Palo Alto, CA found that using only the rate at which movies are mentioned [on twitter] could successfully predict future revenues. But when the sentiment of the tweet was factored in (how favorable it was toward the new movie), the prediction was even more exact. To quantify the sentiments in 3 million tweets the team used the anonymous human workers found by the Amazon Mechanical Turk to rate a sample of tweets, and then trained an algorythmic classifier to derive a rating for the rest

Word on the street is that Google is starting a hedge fund. Someone [Howard Lindzon I’m looking at you] should start a Twitter hedge fund.

The graph above compares the predicted vs actual box office scores of tweet-rates (blue line) and Hollywood Stock Exchange (green line).
