A 125 000-row subset of the [C4 dataset](https://huggingface.co/datasets/allenai/c4)'s English configuration, divided into:
- train: 100 000 rows
- validation: 25 000 rows

Each row contains:
- `text`: Original text
- `lowercased`: Lowercase version of text

## Data Instance Example

```json
{
  "text": "Graduate from Cambridge University, currently doing my masters in International Politics and Economics at LSE.",
  "lowercased": "graduate from cambridge university, currently doing my masters in international politics and economics at lse."
}
```

## Supported Tasks

- Text normalization
- Case-insensitive text analysis

## Limitations

- May contain web-crawled text biases
- English language content
- Small sample size
- Not thoroughly shuffled
