## Dataset Summary 

Himanis (HIstorical MANuscript Indexing for user controlled Search) is a corpus of medieval documents.

The historical corpus is described in the [following publication](https://zenodo.org/records/5535306):
`
Stutzmann, D., Moufflet, J-F., & Hamel, S. (2017). La recherche en plein texte dans les sources manuscrites médiévales : enjeux et perspectives du projet HIMANIS pour l’édition électronique. Médiévales : Langue, textes, histoire 73 (2017): 67‑96. https://doi.org/10.4000/medievales.8198
`

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

### Languages

All the documents in the dataset are written in Latin and in French.

## Dataset Structure

### Data Instances

```
{
  'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=4300x128 at 0x1A800E8E190,
  'text': 'Philippus, Dei gratia Francorum et Navarre rex. Notum facimus universis, tam presentibus quam futuris, quod, cum supplicato nobis nuper,'
}
```

### 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.
