| # Getting PDFs for DefExtra | |
| ## Overview | |
| You must supply PDFs yourself. The dataset does **not** ship any copyrighted excerpts. | |
| See [`README.md`](../README.md) for the high‑level overview and examples. | |
| ## Recommended sources | |
| - **Semantic Scholar**: most `paper_id` values are Semantic Scholar IDs. You can open | |
| `https://www.semanticscholar.org/paper/<paper_id>` and download the PDF when available. | |
| - **DOI landing pages**: use `https://doi.org/<paper_doi>` to locate the publisher PDF. | |
| - **arXiv**: use `https://arxiv.org/abs/<paper_arxiv>`. | |
| - **ACL Anthology**: if a `paper_id` looks like `2024.lrec-main.952`, use | |
| `https://aclanthology.org/2024.lrec-main.952`. | |
| ## Helper script | |
| Generate a CSV of required PDFs and links (pre-generated [in the repo](../defextra_required_pdfs.csv)): | |
| ```bash | |
| uv run python scripts/list_defextra_pdfs.py \ | |
| --legal-csv data/defextra_legal.csv \ | |
| --output-csv defextra_required_pdfs.csv \ | |
| --output-md defextra_required_pdfs.md | |
| ``` | |
| The output includes: | |
| - `preferred_pdf_name` (the filename we recommend you use) | |
| - `alias_pdf_names` (acceptable filename aliases) | |
| - `url_semanticscholar`, `url_doi`, `url_arxiv`, `url_acl` | |
| ## File naming | |
| Place PDFs in one folder and name them as `<paper_id>.pdf` when possible. | |
| DOI/arXiv/PII aliases are supported (see `alias_pdf_names` in the helper output). | |
