Hello Sir,
I am Research Scholar. I m pursuing my master degree and my thesis topic is Sentiment Analysis of reviews using naive bayes algorithm by Rapidminer. Can you provide me Naive Bayes algorithm??? I need it for my research.

you are asking for the code?
Have a look here:

Sir,
In my project, i have classified reviews by using naive bayes algorithm in Rapidminer and in my thesis, i have to improve that technique( improve or enhance naive bayes algorithm) to get better results and increase its accuracy.
or can you provide me any other alternative ?

Linear SVM with optimized C?
Raman
Linear SVM classifier is already choosen by another research scholar in my college. Can you give me any idea how can i improve or change naive bayes algorithm to increase the accuracy ???
MartinLiebig
oh, the trick is not the best algorithm. The trick is do to good feature engeneering.
How did you to your preprocessing?
Raman
first of all, i have done tokenisation, then filter stopwords, filter tokens, stem (Porter), and then tranform cases.
Raman
hello sir...,
what should i do next ?
MartinLiebig
have you tried n-gram? Might be very useful for a naive bayes. This way you can incoperate correlation efeects.
What if you try to optimize different options in your prep?
