## Description

I have used sentiment analysis on 4 different datasets that focus on its tweets, ratings or reviews.

These are :

1. Twitter Dataset

2. Chat Dataset

3. Drugs review dataset

Three types of sentiment are covered - Positive, Negative and Neutral.

## Models Used

1. Logistic Regression

2. Multiclass LR

3. One vs Rest LR

4. Naive Bayes (Gaussian and Multinomial)

5. SVM with linear or rbf kernels

## Datasets used
