APP

You can test this model with this APP in Hugging Face Spaces: Inference APP for Document Understanding at paragraph level (v2).

You can run as well the corresponding notebook: Document AI | Inference APP at paragraph level with a Document Understanding model (LayoutXLM base fine-tuned on DocLayNet dataset)

DocLayNet dataset

DocLayNet dataset (IBM) provides page-by-page layout segmentation ground-truth using bounding-boxes for 11 distinct class labels on 80863 unique pages from 6 document categories.

Until today, the dataset can be downloaded through direct links or as a dataset from Hugging Face datasets:

• direct links: doclaynet_core.zip (28 GiB), doclaynet_extra.zip (7.5 GiB)
• Hugging Face dataset library: dataset DocLayNet

Model description

The model was finetuned at paragraph level on chunk of 512 tokens with overlap of 128 tokens. Thus, the model was trained with all layout and text data of all pages of the dataset.

At inference time, a calculation of best probabilities give the label to each paragraph bounding boxes.
