## Dataset Summary 

The HOME-Alcar (Aligned and Annotated Cartularies) dataset is a Medieval corpus. The 17 medieval manuscripts in this corpus are cartularies, i.e. books copying charters and legal acts, produced between the 12th and 14th centuries. 

This dataset comes from the [following publication](https://doi.org/10.5281/zenodo.5600884):
`
Stutzmann, D., Torres Aguilar, S., & Chaffenet, P. (2021). HOME-Alcar: Aligned and Annotated Cartularies [Data set]. Zenodo. https://doi.org/10.5281/zenodo.5600884
`

Note that all images are resized to a fixed height of 128 pixels.

### Languages

All the documents in the dataset are written in Latin.

## Dataset Structure

### Data Instances

```
{
  'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=4300x128 at 0x1A800E8E190,
  'text': 'quatre mille livres de tournoiz poiez, si com¬'
}
```

### Data Fields


- `image`: a PIL.Image.Image object containing the image. Note that when accessing the image column (using dataset[0]["image"]), the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the "image" column, i.e. dataset[0]["image"] should always be preferred over dataset["image"][0].
- `text`: the label transcription of the image.
