ORKG Core Domain Classifier — Metadata
Update Date: 2026-08-12
Research-domain labels produced by the ORKG Core Domain Classifier for documents in the CORE corpus — one row per document.
The classifier that produces this file lives at https://gitlab.com/TIBHannover/orkg/nlp/experiments/core-domain-classifier.
This card and the CSV are written by python -m app.publish_to_hf in that repository, so
please do not edit them by hand.
