Straight answers about GroupLens Research data
What is the MovieLens tag genome?
A machine-learned matrix pairing movies with descriptive tags by relevance - how strongly a film exhibits a tag's property, scored densely across movies and tags. The 2021 genome edition carries roughly 10.5 million relevance scores over 1,084 tags and 9,734 movies, giving content-based models a feature base before behavior accumulates.
Does the MovieLens corpus include user demographics?
No. Raters appear as anonymized integer identifiers chosen for logging at least twenty ratings each, and no age, gender or location rides along with any row. Segmentation therefore happens on behavior, and any geographic cut needs a join to outside data.
Which rating scale does the corpus use?
Half-star increments from 0.5 through 5.0, stored as numeric values ready for averaging. Event times arrive as unix seconds since midnight UTC on January 1, 1970, so they convert losslessly to calendar dates and timezones without rounding errors.
Can a delivery be scoped to one edition or grain?
Yes. Any vintage from 100K through 32M arrives alone or stacked into a year-over-year panel, and the three grains - ratings, tag applications, genome relevances - ship separately or pre-joined. Scope it at sample request and the delivered schema extends to match.
