Movie Recommendation System

Movie Recommendation System

Project Overview

This is a content-based movie recommendation system built using Python and machine learning libraries. It suggests similar movies to the one selected by a user by analyzing metadata such as genre, keywords, cast, and crew. The core of the system is powered by the TF-IDF vectorizer and cosine similarity.

Key Features

The system incorporates several key features:

• Data Processing: Reads and processes a movie dataset from CSV format.
• Text Vectorization: Converts text features into numerical form using TF-IDF vectorization.
• Similarity Calculation: Calculates cosine similarity between movies based on their textual features.
• Fuzzy Matching: Identifies the most similar movies using the difflib module for fuzzy matching of movie titles.

Technical Implementation

The project utilizes a combination of powerful Python libraries and techniques:

• Pandas & NumPy: For efficient data manipulation and numerical operations.
• Scikit-learn: Provides the TF-IDF vectorizer for text feature extraction.
• Cosine Similarity: Measures the similarity between movies based on their vectorized features.
• Difflib: Implements fuzzy string matching for better user input handling.

Learning Outcomes

Through this project, I gained valuable experience in:

• Handling and processing real-world datasets using pandas.
• Extracting and engineering relevant text features for recommendation systems.
• Implementing content-based filtering using TF-IDF and cosine similarity.
• Enhancing user experience with fuzzy string matching for more flexible input handling.

Technical Challenges

The development process involved overcoming several technical challenges:

• Efficient processing of large text datasets.
• Optimizing the vectorization process for better performance.
• Implementing an effective similarity calculation system.
• Creating a user-friendly interface for movie selection.

The project demonstrates the practical application of machine learning concepts in creating a real-world recommendation system that can help users discover movies based on their preferences.
