## Dataset Description

This dataset is an enriched version of SROIE 2019 dataset with additional labels for line descriptions and line totals for OCR and layout understanding.

## Dataset Structure

```python
DatasetDict({
    train: Dataset({
        features: ['image', 'ocr'],
        num_rows: 652
    })
})
```

### Data Fields

```python
{
    'image': PIL Image object,
    'ocr': [
        #  text box 1
        {
            'box': [[float, float], [float, float], [float, float], [float, float]],
			'label': str,  # "other" | "company" | "address" | "date" | "line_description" | "line_total" | "total"
			'text': str
        },
            ...
        #  text box N
		{
            'box': [[float, float], [float, float], [float, float], [float, float]],
			'label': str,
			'text': str,
        }
    ]
}
```
