pdf files not included in the dataset

[Apurv3377]

I have been working on DocBank_samples since a month now. Today I downloaded the main dataset from onedrive and I could not see any pdf files!
I wanted to request , If it is possible to provide the PDF files too?

I appreciate the help!

I also wonder why no PDFs are provided. Providing only images + annotations puts restrictions on what kind of models can be build. What if I want a model that just takes PDFs and not just images?

Actually, I am also fine if only non-colored PDFs are provided. :) But Yes would be more helpful with annotated.

In fact, the PDF is derived from arXiv's papers during 2014-2018, but we currently have no plan to provide corresponding pdfs. Sorry about this.

Hello @liminghao1630,
thank you for your project. About pdfs, are you planning to publish at least the code for preprocessing them? I mean, if I get a quick look to an original paper corrisponding to your images I see some mismatch between their parts, e.g. images in different pages (and so bound boxes and annotations in general).

Does anyone know if the names of the PDFs are available? In that case I guess one could build a pipeline to download them.

@liminghao1630
It's unfortunate that you do not publish the original files as it prohibits pdf-based models from using this dataset.

I think that from looking at names of the .txt and .jpg files in the dataset one can identify the arxiv URL.
1.tar_1401.0098.gz_TachyonPotentialsV12-PRD-enviado_8.txt => https://arxiv.org/abs/1401.0098 (Title: Tachyon potentials from a supersymmetric FRW model)
1.tar_1501.00050.gz_Godoy-Diana_etal_2014_Enzo_Levi_Workshop_4_ori.jpg => https://arxiv.org/abs/1501.00050 (Title: Four-winged flapping flyer in forward flight)

1.tar_1501.00050.gz_Godoy-Diana_etal_2014_Enzo_Levi_Workshop_4_ori.jpg => arxiv.org/abs/1501.00050

The page number is also available from the filename (0 indexed, so 4 is the 5th page).

I might build a crawler for this if I got time.
