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 Stanford NLP course on Coursera covers Sentiment Analysis in week 3:
- What is Sentiment Analysis?
- Sentiment Analysis: A baseline algorithm
- Sentiment Lexicons
- Learning Sentiment Lexicons
- Other Sentiment Tasks

For coding tutorials see:

These are really basic, so their performance will not be great in all cases.

  • Yeah, the tutorials by StramHacker are the best out there for NLP with Python. – Dawny33 Oct 12 '15 at 5:52
  • The top result on Google for [sentiment analysis with python] links to it, but somehow it itself is not up there. In any case I think adding [with python] drastically shifts the Google results towards practical coding tutorials, my guess is that that exact query formulation simply did not occur to the OP. – A.

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.

As Dawny said i would suggest NLTK Book too. And in R language 'tm' library is pretty useful. So try here for more related text mining stuff with R. r-blog also worth of consider. good luck.
