Twitter Sentiment Analysis

Twitter Sentiment Analysis repository contains a project for performing sentiment analysis on Twitter data using Apache Spark.

Contents

• Sentiment_Analysis.ipynb: Jupyter Notebook containing the code for the sentiment analysis.
• Sentiment.csv: The dataset file containing the Twitter data and sentiment labels.

Project Overview

This project demonstrates how to use Apache Spark for sentiment analysis on Twitter data. The steps covered in the project include:

1. Data Loading: Reading the dataset into Spark DataFrame.
2. Data Cleaning: Preprocessing the data by handling missing values and performing necessary transformations.
3. Feature Engineering: Extracting features from the text data for model training.
4. Model Training: Training a machine learning model to classify the sentiment of tweets.
5. Evaluation: Evaluating the model's performance using appropriate metrics.

Getting Started

Prerequisites

• Apache Spark
• Jupyter Notebook
• Python
• Required Python libraries: pandas, numpy, nltk, pyspark

Installation

1. Clone the repository:

   git clone https://github.com/burhanahmed1/Twitter-Sentiment-Analysis-Using-PySpark.git
   cd Twitter-Sentiment-Analysis-Using-PySpark
   pip install -r requirements.txt
   

2. Install the required Python libraries:

   pip install pandas numpy nltk pyspark
   

3. Start Jupyter Notebook:

   jupyter notebook
   

4. Open Sentiment_Analysis.ipynb in Jupyter Notebook and run the cells to execute the project.

Results

The project demonstrates the effectiveness of using Apache Spark for sentiment analysis on large datasets. The final model achieves good accuracy in classifying the sentiment of tweets.

• The accuracy of the sentiment model using Logistic Regression is 0.62
• Root Mean Squared Error (RMSE) and Explained Variance (R²) using Linear Regression are 0.7331581773635055 and 0.07966124788395001 respectively.
• The accuracy of the sentiment model using Batch Gradient Descent is 0.73
• The accuracy of the sentiment model using Schotastic Gradient Descent is 0.75

Visualizations

Data visualization techniques such as confusion matrices are used to evaluate the performance of the sentiment classification model and scatter plots are used to visualize the distribution and relationships of features in the dataset.
