Moodteller: Estimating mood levels in LiveJournal
Now this is cool. Imagine the implications for such a system in organizations.
We currently analyze approximately 5000 LiveJournal blog posts per hour using statistical language processing methods and estimate, according to the textual features of the posts, the percentage of them which are "happy", "sad", "excited", and so on; we do not use the mood indication given by LiveJournal. After the estimation is done, we check how good it is by examining the real indications given by the bloggers. The graph above shows the estimated and actual values per mood.
