# Semantic Scholar paper ID (`semantic_scholar_paper_id`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Identifier of a paper in Semantic Scholar, the academic search engine of the Allen Institute for AI: 40 lowercase hexadecimal characters, as in https://www.semanticscholar.org/paper/<id>. The Semantic Scholar API also gives each paper a numeric CorpusId, which is a different value. Any SHA-1 hash has the same form, so a match alone does not prove the type. The regexp matches all sampled values of Wikidata property P4011.
