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.
