Using the Naïve Bayes classifier, which is an approach that refers to the Bayes theorem, is a simple classification algorithm but has high accuracy. Naïve Bayes refers to previous knowledge which is strengthened in advance by processing the title text of a new document so that it can be used to facilitate the classification of new document classes.
