The Amazon Reviews 2023 All-Category k-Core dataset is a subset of the Amazon reviews dataset, containing reviews from all categories with more than k (where k is between 5 and 20) interactions. The original dataset includes reviews from May 1996 to September 2023, grouped into 25 categories. The dataset is stored in .parquet format. The k-core definition means that every user and every item has at least k interactions across all categories. The dataset structure includes subdirectories for different core numbers, each containing rating, metadata, and review files for specific categories. The creation and processing of the dataset involve merging ratings from all categories, filtering out ratings with fewer than k interactions, and saving the data in .parquet format.
