Moviebox

Machine learning movie recommending system

Build Status Python Python

Contents

Description

Moviebox is a content based machine learning recommending system build with the powers of tf-idf and cosine similarities.

Initially, a natural number, that corresponds to the ID of a unique movie title, is accepted as input from the user. Through tf-idf the plot summaries of 5000 different movies that reside in the dataset, are analyzed and vectorized. Next, a number of movies is chosen as recommendations based on their cosine similarity with the vectorized input movie. Specifically, the cosine value of the angle between any two non-zero vectors, resulting from their inner product, is used as the primary measure of similarity. Thus, only movies whose story and meaning are as close as possible to the initial one, are displayed to the user as recommendations.

The dataset in use is a random subset of the Carnegie Mellon Movie Summary Corpus, and it consists of 5000 movie titles along with their respective categories and plots.

Install

pip install moviebox

Python 2.7+ or Python 3.4+ is required to install or build the code.

Usage

from moviebox.recommender import recommender

movieID = 2874  # Movie ID of `Asterix & Obelix: God save Britannia`
recommendationsNumber = 3  # Get 3 movie recommendations
showPlots = True  # Display the plot of each recommended movie
interactive = True  # Display process info while running

# Generate the recommendations
recommender(
    movieID=movieID,
    recommendationsNumber=recommendationsNumber,
    showPlots=showPlots,
    interactive=interactive)
