## Dataset Summary |
|
|
|
The Belfort dataset includes minutes of the municipal council of the French city of Belfort. |
|
Text lines were extracted using an automatic model and may contain segmentation errors. The transcriptions were obtained through a crowdsourcing campaign using the [Callico](https://callico.teklia.com/projects/ce9b42d4-23a8-4381-b5bb-459bedc59165/details/) web plateform. |
|
|
|
Note that all images are resized to a fixed height of 128 pixels. |
|
|
|
### Languages |
|
|
|
All the documents in the dataset are written in French. |
|
|
|
## Dataset Structure |
|
|
|
### Data Instances |
|
|
|
``` |
|
{ |
|
'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=4300x128 at 0x1A800E8E190, |
|
'text': 'les intérêts des 30000 francs jusqu'au moment de la' |
|
} |
|
``` |
|
|
|
### 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. |
