# Topic modeling With Naive Bayes Classifier

## Introduction

Naive Bayes is a powerful tool that leverages Bayes’ Theorem to understand and mimic complex data structures. In recent years, it has commonly been used for Natural Language Processing (NLP) tasks, such as text categorization. Today, we will be constructing a Naive Bayes text classifier for topic categorization.

Before we move forward with the explanation, I want to emphasize that Naive Bayes is not the traditional method of classifying topics. In fact, there are other models invented for the specific purpose of classifying topics – such as Blei’s landmark *Latent Dirichlet Allocation. *But although Naive Bayes will be entering a pretty competitive market in topic categorization, its simplicity and easily accessible mathematical foundation make it a unique tool for developers.

Without any further ado, let’s get Naive.

## Packages and Datasets

For this program, we will need to make use of only 2 packages: **pandas** and **textmining**. The former will help us input our data,
