Sentiment analysis

[Pete Warden]

I've put together a simple sentiment analysis endpoint, and made it available on the main DSTK server:

http://www.datasciencetoolkit.org/developerdocs#text2sentiment

The short version is that you make a call like this:

curl -d "I hate this hotel" "http://www.datasciencetoolkit.org/text2sentiment"

and you get a result like this:

{"score": -3.0}

It's based on Finn Årup's annotated word list, and has all the usual sentiment analysis caveats, but has been quite fun to use. It's in the top-of-tree code, but not in any VM or client library yet. I'm hoping to do a full EC2 and Vagrant release within the next few weeks that will include this.

Let me know how you get on with it!

cheers,
