PubLayNet

PubLayNet is a large dataset of document images, of which the layout is annotated with both bounding boxes and polygonal segmentations. The source of the documents is PubMed Central Open Access Subset (commercial use collection). The annotations are automatically generated by matching the PDF format and the XML format of the articles in the PubMed Central Open Access Subset. More details are available in our paper "PubLayNet: largest dataset ever for document layout analysis.".

Ground truth of test set

We have released the ground truth of the test set for the ICDAR 2021 Scientific Literature Parsing competition available here!.

Getting data

Images and annotations can be downloaded here. The training set is quite large, so two options are offered. We split the training set into 7 batches, which can be separately downloaded. Or you can also download the full set at once.

For the ICDAR competition, ids of the image files are available here.

If direct download in browser is unstable or you want to download the data from the command line, you can use curl or wget to download the data.

curl -o <YOUR_TARGET_DIR>/publaynet.tar.gz https://dax-cdn.cdn.appdomain.cloud/dax-publaynet/1.0.0/publaynet.tar.gz

wget -O <YOUR_TARGET_DIR>/publaynet.tar.gz https://dax-cdn.cdn.appdomain.cloud/dax-publaynet/1.0.0/publaynet.tar.gz

To download the PDFs of the document pages contained in PubLayNet:

curl -o <YOUR_TARGET_DIR>/PubLayNet_PDF.tar.gz https://dax-cdn.cdn.appdomain.cloud/dax-publaynet/1.0.0/PubLayNet_PDF.tar.gz

wget -O <YOUR_TARGET_DIR>/PubLayNet_PDF.tar.gz https://dax-cdn.cdn.appdomain.cloud/dax-publaynet/1.0.0/PubLayNet_PDF.tar.gz

Annotation format

The annotation files follows the json format of the Object Detection task of MS COCO
