# LADaS: Layout Analysis Dataset with Segmonto

## Dataset Details

LADaS, created by the [ALMANaCH team-project](https://almanach.inria.fr/index-en.html) at Inria,
continued in partnership with other researchers, is a multidocuments diachronic layout analysis 
dataset. This dataset includes:

- Monographs from the Bibliothèque Nationale de France (17th century - today);
- PhD Thesis, in various fields (not only STEM, 20th-21st century);
- Selling Catalogs (for manuscripts and art pieces), in various fields (18th-20th century);
- Noisy digitization (with fingers for example, 20th-21st century);
- Academic papers (mostly Humanities and Social Sciences) (19th-21st century);
- Magazines about technologies and video games, from 1920s to 2010;
- Misc stuff found here and there.

The data are in YoloV8 bbox format (center_x center_y width height).

The script in document is mostly Latin script, and language is mostly French with some representation of the main
western academic languages.

### Annotations

Label Annotation have been conducted using the [SegmOnto](https://segmonto.github.io/) vocabulary. 
An annotation guide is available [here](https://github.com/DEFI-COLaF/LADaS/blob/25d4cf3f850cf79d18af572153cfbc73deff4160/AnnotationGuide.md).
