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:
- MovieLens 100k, containing 100,000 ratings
- MovieLens 1M, containing about 1,000,000 ratings
- 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)
