OpenAlex L1 + L2 Concepts
What this is
A snapshot of OpenAlex's Level 1 (broad fields) and Level 2 (subfields) concepts: 21,739 records across 284 broad fields and 21,455 subfields.
| Level | Count | Examples |
|---|---|---|
| 1 | 284 | Computer science, Physics, Biology, Sociology |
| 2 | 21,455 | Machine learning, Quantum mechanics, Convolutional neural network |
Each record:
| Column | Type | Description |
|---|---|---|
id |
string | OpenAlex concept ID (e.g., C121955636) |
name |
string | Concept display name |
level |
int | 1 (broad field) or 2 (subfield) |
Source
Derived from OpenAlex, filtered to level:1|2. OpenAlex publishes its data under CC0 1.0, so this derivative is also CC0.
Load it
from datasets import load_dataset
ds = load_dataset("barissozudogru/openalex-concepts")
print(ds["train"][0])
# {'id': 'C121955636', 'name': 'Accounting', 'level': 1}
Or directly with pandas:
import pandas as pd
df = pd.read_csv("hf://datasets/barissozudogru/openalex-concepts/concepts.csv")
print(df[df["level"] == 1].head())
Use cases
- Topic classification or tagging for academic papers
- Vocabulary for concept-aware retrieval and federated search
- Building lookup tables from OpenAlex concept IDs to display names
- Training topic-classification models with a stable, offline-usable taxonomy
Caveats
- This is a snapshot, not a live mirror. OpenAlex's concept tree is updated periodically; rebuild from the source if you need the latest.
- OpenAlex deprecated their concepts API in favor of topics in late 2024; concepts remain available but are no longer the primary OpenAlex tagging system. Use accordingly.
- IDs are stable per concept but the wider OpenAlex taxonomy may reorganize over time.
