The Netflix Prize data is a dataset of movie ratings provided by Netflix, which was released in 2006 for a competition to improve the accuracy of their movie recommendation system. The dataset consists of over 100 million movie ratings from over 480,000 customers, spanning over 17,000 movie titles. The ratings are on a scale of 1 to 5 stars, and were collected over a period of several years. The dataset was made available to the public for research purposes, and has since been used in various machine learning and data science projects. The competition was won in 2009 by a team called "BellKor's Pragmatic Chaos," which achieved a 10.06% improvement in prediction accuracy over Netflix's existing system.
