    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 ?

    oh, the trick is not the best algorithm. The trick is do to good feature engeneering.

    How did you to your preprocessing?

    first of all, i have done tokenisation, then filter stopwords, filter tokens, stem (Porter), and then tranform cases.

    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?
