I used the code in this repo for my blog post: http://mayhewsw.github.io/2022/05/03/how-old-are-acl-references/
See individual files for comments.

$ python -m venv .pyenv
$ source .pyenv/bin/activate
$ pip install -r requirements.txt
The data is already included in the data/
folder, but you can download it again with:
$ python download_paper_year_data.py
