ORKG Core Domain Classifier — Metadata

Update Date: 2026-08-14

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.

Usage

from datasets import load_dataset

dataset = load_dataset("MikeACedric/Domain_Classifier_Dataset", split="train")

Schema

Column	Description
id	document id — a plain CORE id (100000028) or a prefixed one (TIBKAT:1738662721)
predicted_domain	research domain assigned by the classifier
