Code-R57 / MovieRecommendationSystem

A project to scrape data from 3 sources (IMDb, Rotten Tomatoes and Metacritic) to create a data set for the Knowledge Graph (on Neo4j) that is used as the source of data for the Movie Recommender.

Movie Recommendation System

The motive of the project is to scrape information of movies from IMDb, Rotten Tomatoes and Metacritic to collect the data for a Knowledge Graph that is used as the source of data for a Movie Recommendation System.

Features

• Scrapes data from the websites.
• Processes the data to remove HTML tags and Unicode values.
• Creates necessary CSV (Comma-Separated Values) file to be imported into the knowledge graph.
• Connects Neo4j Aura Database (knowledge graph built) to the Python program.
• Provides a simple GUI platform to get the top 5 recommended movies based on the movie searched.

Installation and Running the Code

Note: Make sure python and pip are properly installed on the system.

1. Install the Necessary Libraries (For 1st time users having one or many of these libraries not installed already)

   1. Run the following in the terminal or cmd:

   pip install beautifulsoup4
   pip install requests
   pip install html5lib
   pip install regex
   pip install pandas
   pip install scikit-learn
   pip install neo4j
   pip install python-dotenv
   

2. Scrape Data (If you want to generate or update the scraped values in Scraped Data folder)

   1. Open the IMDbScraping.py file and run the code.
      It will create or update the imdb_movie_list.csv in the Input folder with the current values of the top 250 movies on IMDb.
   2. Repeat step ii with RottenTomatoesScraping.py and MetacriticScraping.py files.
      It will update the respective files based on the list of movies in the imdb_movie_list.csv file.
   3. Now, run the ProcessingData.py file.
      This processes the data into movies.csv and ratings.csv files, which are used as input files for further data processing.
   4. Open the Jupyter Notebook named MovieRecommendationSystem.ipynb and run the program as specified in the notebook.
      This generates the necessary output files to import to the Neo4j instance.

3. Create the Knowledge Graph (Neo4j Graph Database)

   1. Login into your neo4j account (create if it does not exist).
   2. Create an AuraDB instance.
   3. Save the credentials .env file in the project folder and update the folder name in the MovieRecommendationSystem.ipynb and MovieRecommender.py files.
   4. Click on import to open the import portal of the neo4j platform.
   5. Add the CSV files present in the Output folder.
   6. In the options menu, click Open model and select neo4j_importer_model.json present in the project folder.
   7. Click on Run Import. The values will be imported into the database.

4. Run the Movie Recommender

   1. Now, run the code in the Connecting the code to Neo4j Database and Running a Sample Query section of the Jupyter Notebook to test the connectivity of the neo4j database and python code.
   2. Run the MovieRecommender.py.
      It will open the GUI window. Select the criteria as given in the program and select the movie. The output will provide the top 5 recommended movies based on the similarity score.
