A curated collection of public datasets for recommender systems research, spanning domains like books, movies, music, e-commerce, and dating. It links to well-known sources such as MovieLens, Amazon reviews, and LastFM, with descriptions and some pre-processed academic variants.

Use cases

• find datasets to benchmark recommender system algorithms
• download MovieLens-style rating data for collaborative filtering experiments
• get e-commerce click and purchase logs for recommendation research
• locate music listening datasets for implicit feedback models
• find pre-processed datasets for academic RS papers

When to choose

• you need real-world rating or interaction data to train or evaluate recommendation models
• you want a quick index of well-known recommender system datasets across domains
• you are doing academic experiments and want pre-processed benchmark data

When to avoid

• you need a software library or tool rather than data
• you require guaranteed open licenses - some listed datasets need permission or citation
• you need actively maintained or freshly updated datasets
