MovieLens is a recommender system and virtual community website that recommends films based on user-provided ratings.

Three different datasets contained from the MovieLens system have been released by the GroupLens research group:

  1. MovieLens 100k, containing 100,000 ratings
  2. MovieLens 1M, containing about 1,000,000 ratings
  3. MovieLens 10M, containing about 10,000,000 ratings, plus tagging information

All datasets additionally contain additional movie and user attributes, in particular:

  • the movies' IMDB keys, allowing easy access to more movie attributes using IMDB's plain text data files,
  • movie release dates and genres
  • user age, gender, postal code, and occupation (not for MovieLens 10M)
