We have released a minor update of our twitter sentiment analysis code. This resolves a minor feature extractor bug identified by Rahul Devan.
The updated classifer code can be found in the Lab page.
We have released a free Python code for sentiment analysis.
It's a simple demonstration program that works with the Twitter Sentiment Corpus, which we also distribute.
Both the classifier code and the corpus can be found in our Lab page.
We've just released version 0.2 of the free Twitter Sentiment Corpus.
It has an updated Python downloader script. The script is more robust in handling download errors. It also fixes a unicode error when writing the final results corpus.
If you've already started downloading tweets using the v0.1 release:

PS: if you're curious why this the installer script hassle is necessary, here is our conversation with twitter regarding their Terms of Service.
We've just released a free corpus for Twitter sentiment analysis.
Right now, it's got over 5500 hand-classified tweets spread over 4 topics. This is just the first release. If we receive enough positive feedback from the community, we'll continue to improve this data set.
Because of Twitter's licensing rules, we can not include the actual tweet texts. Instead, an included python script downloads the tweets for you. If you have the connections inside Twitter to get us an exemption from this restriction, please drop us a line at email@example.com.
It can be downloaded from the Twitter Sentiment Corpus page.
