# Amazon Reviews 2023

**Please also visit [amazon-reviews-2023.github.io/](https://amazon-reviews-2023.github.io/) for more details, loading scripts, and preprocessed benchmark files.**

**[April 7, 2024]** We add two useful files:

1. `all_categories.txt`: 34 lines (33 categories + "Unknown"), each line contains a category name.
2. `asin2category.json`: A mapping between `parent_asin` (item ID) to its corresponding category name.

---

<!-- Provide a quick summary of the dataset. -->

This is a large-scale **Amazon Reviews** dataset, collected in **2023** by [McAuley Lab](https://cseweb.ucsd.edu/~jmcauley/), and it includes rich features such as:
1. **User Reviews** (*ratings*, *text*, *helpfulness votes*, etc.);
2. **Item Metadata** (*descriptions*, *price*, *raw image*, etc.);
3. **Links** (*user-item* / *bought together* graphs). 

## What's New?

In the Amazon Reviews'23, we provide:

1. **Larger Dataset:** We collected 571.54M reviews, 245.2% larger than the last version;
2. **Newer Interactions:** Current interactions range from May. 1996 to Sep. 2023;
3. **Richer Metadata:** More descriptive features in item metadata;
4. **Fine-grained Timestamp:** Interaction timestamp at the second or finer level;
5. **Cleaner Processing:** Cleaner item metadata than previous versions;
6. **Standard Splitting:** Standard data splits to encourage RecSys benchmarking.

## Basic Statistics

> We define the <b>#R_Tokens</b> as the number of [tokens](https://pypi.org/project/tiktoken/) in user reviews and <b>#M_Tokens</b> as the number of [tokens](https://pypi.org/project/tiktoken/) if treating the dictionaries of item attributes as strings. We emphasize them as important statistics in the era of LLMs.

> We count the number of items based on user reviews rather than item metadata files. Note that some items lack metadata.
