World Language Data Collection

23,740 languages: Glottolog, WALS, PHOIBLE + integrated world languages

Curated collection of linguistic datasets with original integration work. Includes geographic coordinates, typological features, phonological inventories, language family trees, and an integrated world languages dataset merging Glottolog, Joshua Project, and language history data. Original work under MIT; source data under CC-BY-4.0 (Glottolog, WALS) and CC-BY-SA-3.0 (PHOIBLE).

Dataset Structure

See demo_notebook.ipynb for data exploration examples.

Usage

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("lukeslp/language-data")

# Or load from local files
import json
with open('data.json') as f:
    data = json.load(f)
