Simple python script that extracts citation graphs of COVID-19 publications from the CORD-19 open research dataset.
Last updated for CORD-19 release 6/2/2020.
This graph is included as a sample graph in Argo Lite.
Since the CORD-19 dataset has updated schema and introduced breaking changes, the code for one release of the dataset might not work for another. Please check the CORD-19 change log.
Download the CORD-19 dataset. Unzip and organize into the following directory structure (relative to generate.py at the root repository folder).
generate.py
cord-2020-06-02/
metadata.csv
document_parses/
pdf_json/*
pmc_json/*
You can name the dataset folder (cord-2020-06-02 above for illustration) to whatever you want, just remember to change the paths in the code.
