MovieLens 32M

Parquet republication of the GroupLens MovieLens ml-32m release. This is not the official GroupLens download. The release has no train/test files. Each config has one split, train, containing every row of that CSV. The authors say cross-validation is left to the user.

Original sources

There is no separate GitHub repository for this data release. GroupLens publishes the files from the pages above.

CSV fields are kept as VARCHAR. user_id, movie_id, rating_value, event_at, and tmdb_id are typed projections. imdbId stays text so leading zeros remain. event_at is the Unix timestamp column. source_row is the 1-based CSV data line, assigned before sorting. Tables are not joined. No creator table, item version, or rolling statistic is derived.

License

The GroupLens research license in the upstream README.txt applies. The dataset may be used for research if use is acknowledged, it is not presented as endorsed by the University of Minnesota or GroupLens, redistribution keeps these conditions, and commercial or revenue-bearing use needs permission from GroupLens.
