This is the processed version of [Google's C4 dataset](https://www.tensorflow.org/datasets/catalog/c4). |
|
|
|
We prepared three variants of the data: `en`, `en.noclean`, and `realnewslike`. There is a fourth one, `webtextlike`, which was not ready as I am writing this, but we are working on it. If you are interested in the `multilingual` version, please get in touch. |
|
|
|
For reference, these are the sizes of the variants: |
|
|
|
- `en`: 300GB |
|
- `en.noclean`: 2.3TB |
|
- `realnewslike`: 15GB |
|

# How do I download this? |
|
|
|
Unfortunately we ran out of time making this into a proper Huggingface dataset, accessible through the `datasets` Python package. Until we get that ready, please use git to do the download. First, make sure you have [Git Large File Storage](https://git-lfs.github.com) installed. Once that is done, downloading the whole dataset, all three variants, is easy: |
|
|
|
```bash |
|
git clone https://huggingface.co/datasets/allenai/c4 |
|
``` |
|
|
|
If you want only one of the variants, you need some more commands: |
|
|
|
```bash |
|
git clone -n https://huggingface.co/datasets/allenai/c4 |
|
cd c4 |
|
git sparse-checkout init --cone |
|
git sparse-checkout set en |
|
``` |
|
|
|
You can use `git sparse-checkout set` multiple times to select multiple datasets. |

Big ups to the good folks at [Common Crawl](https://commoncrawl.org) whose data made this possible ([consider donating](http://commoncrawl.org/donate/)!), to Google for creating the code that curates and filters the data, and to Huggingface, who had no issue with hosting these 3TB of data for public download! |
