Sentiment Analysis Tutorial

Question

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.

Answer 1

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:

• Stream Hacker's NLP tutorials

• Basic Sentiment Analysis with Python

• Andy Bromberg's Sentiment Analysis tutorials

• Laurent Luce's Sentiment Analysis tutorials

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

Answer 2

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.

Answer 3

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.
