Kerry Raymond: "A really exciting result would be the ability to predict
stock price movements from WP editing behaviour!"
I am actually funded by a project where we are trying that. We have
looked a bit on Twitter sentiment (like everyone else is doing), but now
also do Wikipedia sentiment analysis for companies.
You see an example here for the Lundbeck pharmaceutical company:
http://rb.imm.dtu.dk/base/c/Lundbeck
The plots are for Wikipedia sentiment through time, Twitter sentiment
through time and stock price (plots not aligned temporally).
Lundbeck had bad publicity last year. One of their drugs was, without
their acceptance, used for executions in United States. There is a drop
in Twitter sentiment in regard to that issue -- and also a slight drop
in Wikipedia sentiment. It is unclear to me whether the stock price
movement is related to that media issue.
I have not completed the analysis. But you see some further companies
here

Danish companies I have run through the sentiment analysis.
