ORKG Core Domain Classifier — Metadata

Update Date: 2026-10-01

Research-domain labels produced by the ORKG Core Domain Classifier — one row per document.

The classifier that produces this file lives at https://gitlab.com/TIBHannover/orkg/nlp/experiments/core-domain-classifier. This card is generated, so please do not edit it by hand.

Load the dataset

from datasets import load_dataset

dataset = load_dataset("TIB/ORKG-core-domain-classifier-dataset", split="full")

print(dataset[0])
# {'id': '100000028', 'predicted_domain': 'Biomedical Engineering and Bioengineering'}

Filter to a single domain, or look up one document:

predicted_domain	research domain assigned by the classifier

How the labels were produced

Each label is the output of an LLM prompted with the document's title, abstract and topics. They are model predictions, not human annotations, and there is no gold-standard evaluation set. Labels are drawn from a fixed vocabulary of research domains, published as app/assets/domains.json in the source repository.
