Best Movie Review Sentiment Analysis Using Django

Movie Review Sentiment Analysis

A simple yet powerful web application built using Python and Django, the Movie Review Sentiment Analyser is designed to analyze the sentiments behind movie reviews gathered from multiple sources. The system automatically fetches reviews using both API integration and web scraping techniques, processes them using sentiment analysis algorithms, and provides a cumulative score for each movie — comparing the actual movie rating with the calculated sentiment-based rating.

This project is an excellent demonstration of how Natural Language Processing (NLP) and Machine Learning concepts can be practically applied to real-world use cases such as movie rating analysis and review aggregation.

Project Overview

Introduction

A simple project on Movie Review Sentiment Analysis built using the Django framework provides users with a seamless platform to analyze public opinions about movies. Instead of relying solely on numeric ratings, this project dives deep into textual reviews, interpreting whether the audience sentiment is positive, negative, or neutral.

In today’s digital age, reviews play a vital role in influencing decisions. However, not all reviews are numerical; most are descriptive and emotion-driven. This is where sentiment analysis becomes essential — it quantifies emotions and provides a structured understanding of how people feel about a movie.

This project was developed with the aim of helping students and developers learn how machine learning models and text analysis techniques can be integrated into a Django web app to process real-time data from multiple sources.

Available Features

The Movie Review Sentiment Analyser project comes with a well-defined set of features that work efficiently together. Each feature is implemented using Django views, templates, and models, ensuring smooth data flow throughout the system.

1. Review Fetching from API

The system connects with a movie review API to fetch authentic and recent reviews for selected movies. These reviews are processed dynamically, ensuring that sentiment analysis is applied on the latest audience feedback.

2. Web Scraping Integration

Apart from the API, the project uses web scraping (using Python libraries such as BeautifulSoup or requests) to collect movie reviews from trusted online sources. This feature enhances the accuracy and diversity of the dataset used for sentiment analysis.

3. Sentiment Analysis on Reviews

Once reviews are collected, they are cleaned and processed to remove unwanted characters, stop words, and symbols. A sentiment analysis model then classifies each review as positive, negative, or neutral. This classification helps in calculating the overall sentiment percentage.

4. Cumulative Sentiment Scoring

The project compares the actual movie rating (fetched from the API) with the sentiment-derived rating calculated by the algorithm. This dual-scoring mechanism offers an unbiased, data-driven representation of how the audience truly perceives the movie.

5. User-Friendly Web Interface

The front-end is designed with simple and clean HTML/CSS templates. Users can search for a movie, view its actual rating, analyze audience sentiment, and see summarized results presented in an easy-to-read format.

6. Django Admin Dashboard

The project includes a Django-powered admin panel that allows the developer or administrator to manage movie records, view stored reviews, and monitor sentiment outputs. This backend interface is helpful for debugging and data inspection during development.

Installation Guide (For VS Code)

Follow the below steps carefully to set up and run the project using Visual Studio Code (VS Code) on your local machine.

Step 1: Extract the Project Folder

After downloading the project, extract the ZIP file. You will find a directory named similar to:

Movie-Review-Sentiment-Analyser/

Step 2: Open Project in VS Code

Launch VS Code and open the extracted project folder.

Step 3: Create a Virtual Environment

Creating a virtual environment keeps your dependencies isolated:

python -m venv venv

Activate it:

• On Windows: venv\Scripts\activate
• On macOS/Linux: source venv/bin/activate

Step 4: Install Dependencies

The project dependencies are listed in the requirements.txt file. Run the following command:

pip install -r requirements.txt

Step 5: Apply Database Migrations

Now, create the necessary database tables:

python manage.py migrate

Step 6: Run the Development Server

Once everything is set up, start the Django development server:

python manage.py runserver

Step 7: Access the Web App

Open your browser and navigate to:

http://127.0.0.1:8000/

You will now see the Movie Review Sentiment Analyser homepage running successfully.

Usage Guide

The project is designed to be simple and intuitive, so both developers and end users can interact with it effortlessly.

For Regular Users:

1. Open the homepage and enter a movie name in the search field.
2. The system automatically fetches reviews using an API and web scraping.
3. It processes these reviews through sentiment analysis.
4. Finally, it displays the average sentiment score along with the movie’s official rating.
5. The user can compare the two results to see if audience emotions align with the critic-based ratings.

For Developers and Students:

• Developers can explore how sentiment analysis works in real-time web applications.
• The Django codebase demonstrates integration of Python’s NLP capabilities with web frameworks.
• Students can modify the existing sentiment algorithm, try different NLP models, or connect new data sources to improve accuracy.

For Admins:

1. Log in to the Django admin panel using the superuser credentials.
2. Admins can manage movie records, view stored reviews, and check analyzed sentiment results.
3. The dashboard helps in verifying whether fetched reviews and calculated sentiments are correctly stored and processed.

How This Project Helps Students

From a student’s perspective, this project provides hands-on experience in multiple core areas of computer science and AI, including:

• Django Web Development: Understanding the MVC (Model-View-Controller) structure and how Django handles web routing and data rendering.
• API Integration: Learning to fetch and process live data using REST APIs.
• Web Scraping: Understanding data extraction using BeautifulSoup and handling dynamic content.
• Natural Language Processing (NLP): Performing real sentiment analysis using text data.
• Data Handling: Managing structured and unstructured data in a relational database.
• Practical Machine Learning Application: Applying algorithms to a real-world scenario instead of theoretical datasets.

This project is also an excellent choice for academic submissions, as it covers a variety of topics including machine learning, web development, and data analytics, all within one cohesive system.

In real-world terms, such systems can be expanded and deployed to analyze reviews for e-commerce products, restaurants, or even political opinions — proving that the underlying concept has versatile applications beyond movie analysis.

Real-Life Application

The Movie Review Sentiment Analyser is not just an academic project — it reflects a real-world system that could be integrated into online review platforms or movie rating websites. By combining traditional ratings with public sentiment, movie streaming services or review aggregators could provide more reliable, emotion-based insights for users.
