+# Dataset Card for Wikipedia
+
+This repo is a fork of the original Hugging Face Wikipedia repo [here](https://huggingface.co/datasets/wikipedia).
+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](https://github.com/huggingface/olm-datasets) to pull and process up-to-date wikipedia snapshots.

+
+### 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:
+
+```python
+from datasets import load_dataset
+
+load_dataset("olm/wikipedia", language="en", date="20220920")
+```
+
+You can find the full list of languages and dates [here](https://dumps.wikimedia.org/backup-index.html).
+
+### Supported Tasks and Leaderboards
+
+The dataset is generally used for Language Modeling.
+
+### Languages
+
+You can find the list of languages [here](https://meta.wikimedia.org/wiki/List_of_Wikipedias).
+
+## 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.
