Twitter mood predicts the stock market
The original article is here uploaded on the 14th of October. Back in June I was toying with the idea of doing twitter surveillance to predict health outcomes in populations as part of my research and, of course, a side project would have been on the go for predicting the stock market (since after all, stock market data is much easier to get than health data). Looks like we should have started it properly in June, because we have now been beaten. Some very nice work, and worth a little look see before it hits the mainstream news.
