The NLTK python lib is a great tool. I've been playing around with this recently and having a lot of fun. More recently I started looking at SCOTUS oral transcripts:

The two articles here by the same author are interesting for folks who are interested in more about sentiment analysis

Needs more cowbell. "Wasn't that a fucking great movie?" => 0.7 Negative sentiment.

"A better film has never been made. If this film was any better, it would simply cease to exist. Really, nothing about it could be improved. I have no complaints whatsoever about the acting, the script, or the cinematography. I was sad to see it end. I am going to go back tomorrow and watch it again."

1.0 Negative sentiment

WOW! That is unbelievable. Usually things get better with more tokens. What a broken library.

At least it got this one correct. "Mr. Madison, what you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul." 0.8 Negative Sentiment.

I wrote an article on use the NLTK library for gender prediction http://stephenholiday.com/articles/2011/gender-prediction-wi...

It's quite a versatile library.
