# 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](https://core.ac.uk/) corpus — one row per document.

The classifier that produces this file lives at [https://gitlab.com/TIBHannover/orkg/nlp/experiments/core-domain-classifier](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

```python
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 |
