Ask HN: Boring but important tech no one is working on
Check this project from AllenAI called PdfFigures: they also extract tables

Project to rebuild papers with plaintext markup languages
- pdffigures2 is from the team behind Semantic Scholar, and they probably use it to extract the figures that they show in their search engine. It only extracts figures and their captions and no other things. I don't recall whether the other tools can also extract figures, but if not, then this will be a perfect supplement.

Extract research paper`s references
I would suggest using grobid - a pipeline for extracting scientific PDFs into a common XML format which can be easily parsed. Grobid has quite a nice mature REST API that I've used in some of my own projects. It parses references and matches them to their DOI using the CrossRef API with a reported 95% F1 score. This should make your job pretty simple as far as I can tell - all you'd need to do is run your papers through grobid and then build a citation graph by comparing document DOIs.

Just use science-parse or GROBID. They have been designed for that exact reason.

Project to rebuild papers with plaintext markup languages
- I ended up using Grobid, which converts the PDF to a very detailed XML format. The format is not a word processing format though, but a format specifically for representing scientific documents. I don't know, if it would, for example, contain tags about bold or italicized text. The tool is working really well, but since you probably cannot use the output XML format directly, it will need some postprocessing, which would be relatively simple with XML parsing libraries.

[D] What pdf parser do you use for paragraph parsing for huggingface models
A few years ago I evaluated a few open source tools. In the end focused on GROBID. As usual, it depends on the type of document whether it works well for your use-case. There is some focus on it being "fast" (if that is a concern).
