🚀 Wikipedia Monthly

Last updated: August 02, 2025, 17:47 UTC

This repository provides monthly, multilingual dumps of Wikipedia, processed and prepared for easy use in NLP projects.

📊 Live Statistics

Metric Value
🌍 Languages Available 29
📄 Total Articles 402,139
💾 Total Size 0.13 GB

Why Use This Dataset?

  1. Freshness: We run our pipeline monthly to capture the latest versions of all articles.
  2. Clean & Ready: We handle the messy parts of parsing MediaWiki markup. You get clean plain text ready for use.
  3. Easy Access: Load any language with a single line of code using 🤗 datasets.

Usage 

from datasets import load_dataset

# Load the English dataset from the latest dump
dataset = load_dataset("omarkamali/wikipedia-monthly", "latest.en", split="train", streaming=True)

🌍 Language Subsets

This dataset is organized into configurations, one for each language dump. The table below lists all available subsets. For new languages, the article count will show as "Processing..." until the first full run is complete.

Dataset Creation Process

Our pipeline is designed for transparency and robustness:

  1. Download: We fetch the latest pages-articles.xml.bz2 dump for each language directly from the official Wikimedia dumps server.
  2. Filter: We stream the dump and process only main articles (namespace 0), filtering out user pages, talk pages, and other metadata.
  3. Process: Using mwparserfromhell, we parse the MediaWiki syntax to extract clean, readable content.
  4. Format: We generate a plain text representation by applying additional post-processing on the output from mwparserfromhell.
  5. Upload: The resulting dataset is uploaded to the Hugging Face Hub with a configuration name corresponding to the dump date and language (e.g., 20250710.en).

Data Fields

Each row in the dataset corresponds to a single Wikipedia article and contains the following fields:

  • id: The unique Wikipedia page ID (string).
  • url: The URL to the live article (string).
  • title: The title of the article (string).
  • text: The clean, plain text content of the article (string).
  • raw_mediawiki: The original, unprocessed MediaWiki source content (string).
