 # 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).

-### Dataset Description
-
-
-- **Curated by:** Thibault Clérice & Juliette Janès
-- **Funded by:** Défi COLaF, Inria
-- **License:** CC-BY
-
-## Uses
-
-### Direct Use
-
-- Layout Analysis
-
-## Dataset Structure
-
-You'll find 8 fields in the parquet:
-
-- `image_path` is a string identifier for the file
-- `year` is the year of production. It can be null.
-- `dating-certainty` is used to specify when a date is automatically provided based on a date range and a century range. They will usually be centuries, such as 1600.
-- `set` represents the subset of the data, there are a few, including `theatre` for plays, `monographies` for monographs, `theses` for PhD thesis, etc.
-- `image` contains the image
-- `width` and `height` are quite clear...
-- `objects` is a dictionary with entries:
-  - `bbox` which represents a series of bbox using the COCO / YOLO format (tuple of relative center_x, center_y, width, height)
-  - `category` which contains a plain text representation of the annotation class of each bbox. There are 41 classes, further described on the annotation guide.
-  - `objects` can contain an empty `bbox` list and an empty `category` list: it means the image does not contain any objects.
-### Annotations
-
-#### Annotation process
-
-The annotation process is described in the [dataset paper](https://inria.hal.science/hal-04513725).
-
-#### Who are the annotators?
-
-- Clérice, Thibault
-- Janès, Juliette
-- Scheithauer, Hugo
-- Bénière, Sarah
-- Bougrelle, Roxane
-- [Anonymous place holder until a paper is published]
