Sentiment Analysis Tutorial I am trying to understand sentiment analysis and how to apply it using any language (R, Python etc). I would like to know if there is a good place on internet for tutorial that I can follow. I googled, but I wasn't very much satisfied because they were not tutorials but more of theory. I want theory and practical examples.
The NLTK book is by far the best tutorial on basic NLP I have seen(in Python).

The Coursera course on NLP is also fairly good. It takes off from the basics and takes the student to a novice level.
