<!-- 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. |
