Dataset Card for Wikipedia

This repo is a fork of the original Hugging Face Wikipedia repo here. The difference is that this fork does away with the need for apache-beam, and this fork is very fast if you have a lot of CPUs on your machine. It will use all CPUs available to create a clean Wikipedia pretraining dataset. It takes less than an hour to process all of English wikipedia on a GCP n1-standard-96. This fork is also used in the OLM Project to pull and process up-to-date wikipedia snapshots.

Dataset Description

Dataset Summary

Wikipedia dataset containing cleaned articles of all languages. The datasets are built from the Wikipedia dump (https://dumps.wikimedia.org/) with one split per language. Each example contains the content of one full Wikipedia article with cleaning to strip markdown and unwanted sections (references, etc.).

The articles are parsed using the mwparserfromhell tool, and we use multiprocess for parallelization.

To load this dataset you need to install these first:

pip install mwparserfromhell==0.6.4 multiprocess==0.70.13

Then, you can load any subset of Wikipedia per language and per date this way:

from datasets import load_dataset

load_dataset("olm/wikipedia", language="en", date="20220920")

You can find the full list of languages and dates here.

Supported Tasks and Leaderboards

The dataset is generally used for Language Modeling.

Languages

You can find the list of languages here.

Dataset Structure

Data Instances

An example looks as follows:

{'id': '1',
 'url': 'https://simple.wikipedia.org/wiki/April',
 'title': 'April',
 'text': 'April is the fourth month...'
}

Data Fields

The data fields are the same among all configurations:

  • id (str): ID of the article.
  • url (str): URL of the article.
  • title (str): Title of the article.
  • text (str): Text content of the article.
