OpenAlex

Updated: Feb 23, 2022

Preprocessing

0. Create the sci-sci conda environment from environment.yml.
1. Download the OpenAlex snapshots from this link to a directory of your choosing (say, basedir).
2. Open preprocessing/flatten_openalex_files.py and update the BASEDIR variable to the above directory.
3. Uncomment and run flatten_<entity> functions to generate the flattened compressed CSV files.

• The flatten_works() function generates CSV and Parquet files at the same time.

Warnings:

• flattening authors and works take anywhere between 15 and 30 hours. The code will cache the files, so you should consider running it in batches by setting the files_to_process variable.

Coming Soon

• Filtering CSVs based on concepts, publication years, and venues
