This is a large-scale Amazon Reviews dataset, collected in 2023 by the McAuley Lab. It includes rich features such as user reviews (ratings, text, helpfulness votes, etc.), item metadata (descriptions, prices, raw images, etc.), and links (user-item/bought together graphs). The dataset is notable for its larger size (571.54M reviews, 245.2% larger than the previous version), newer interactions (ranging from May 1996 to Sep 2023), richer metadata, finer-grained timestamps (at the second or finer level), cleaner processing, and standard data splits to encourage recommendation system benchmarking. The dataset is organized by categories such as All_Beauty, Electronics, Toys_and_Games, etc., each with detailed statistics on users, items, ratings, and tokens.
