# 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](https://huggingface.co/datasets/omarkamali/wikipedia-monthly) and is maintained by [omarkamali](https://huggingface.co/omarkamali).

## Dataset Structure

The dataset is provided in **Hugging Face format** with three distinct splits:

1.  **`default`**: Primary localized label for each namespace.
3.  **`strict`**: Filtered version removing major language fallbacks (**en, fr, es, ar, ru, zh**).
2.  **`all`**: List of all known labels and aliases per namespace.

## Usage

```python
from datasets import load_dataset
ds = load_dataset("omarkamali/wikipedia-labels")
```

## Cleaning Metrics (Strict Split)

Top 50 languages with labels removed because they matched a major source language:
