Wikipedia Structural Labels Dataset
This dataset contains structural labels (namespaces and their aliases) for 358 Wikipedia languages. It is designed to help researchers and developers clean Wikipedia content by identifying and removing structural noise (e.g., "Category:", "File:", "Template:") across all supported languages.
This is a sister project to wikipedia-monthly and is maintained by omarkamali.
Dataset Structure
The dataset is provided in Hugging Face format with three distinct splits:
default: Primary localized label for each namespace.strict: Filtered version removing major language fallbacks (en, fr, es, ar, ru, zh).all: List of all known labels and aliases per namespace.
Usage
from datasets import load_dataset
ds = load_dataset("omarkamali/wikipedia-labels")
