Metadata enriching steps | |
|---|---|
1. Match the paper with its DOI via the Crossref API [11] | |
2. If DOI matched, check Semantic Scholar for metadata/abstract [12] | |
3. If no DOI match and no abstract, search PubMed for abstract | |
4. Search arXiv [13] (for a pre-print) | |
5. If no PDF link, search Unpaywall for available open access versions [14] | |
6. If PDF but no separate abstract via Semantics Scholar/PubMed, extract abstract from the PDF |
