Using Wikipedia for predicting stock market is being done from some time ago.
Obviously, the more stream data you have (Wikipedia, Twitter, Facebook, ...), the more info you can extract and attempt to "predict" some changes in the stock. Anyway, although Wikipedia license allows reusing the info for any case, I think that this is a sad case. The effects of stock markets include famines (speculation of food prices) and other basic goods. A death machine. A more humane approach for this "big data" is what Google did with their searches. For example, detecting the spread of flu when people search "headache" and similar terms. 2012/11/8 Taha Yasseri <[email protected]> > I think that's a brilliant idea.
