### Dataset Summary

Wikipedia dataset containing cleaned articles of the Standard Arabic Wikipedia version and the linked articles from the English version.

| Language | Articles       | Tokens *       | Characters |
|----------|----------------|----------------|------------|
| English  | 882,534         | 1,177.94 M    | 5014.68 M  |

### Original model card
The dataset is built from the Wikipedia dumps (https://dumps.wikimedia.org/)
with one subset per language, each containing a single train split.

Each example contains the content of one full Wikipedia article with cleaning to strip
markdown and unwanted sections (references, etc.).


All language subsets have already been processed for recent dump, and you can load them per date and language this way:
```python
from datasets import load_dataset

ds = load_dataset("wikimedia/wikipedia", "20231101.en")
```

#### Data Visualization
Click the [Nomic Atlas](https://atlas.nomic.ai/map/475c26d7-b142-4795-9887-02b6eeb18dc0/0d312be6-a3bb-4586-b6b7-53dcd0cbefa5) map below to visualize the 6.4 million samples in the `20231101.en` split.

### 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.

### Data Splits

All configurations contain a single `train` split.

## Dataset Creation

### Curation Rationale

[More Information Needed]

### Source Data

#### Initial Data Collection and Normalization

The dataset is built from the Wikipedia dumps: https://dumps.wikimedia.org

You can find the full list of languages and dates here: https://dumps.wikimedia.org/backup-index.html

The articles have been parsed using the [`mwparserfromhell`](https://mwparserfromhell.readthedocs.io) tool.

When uploading the data files for the 20231101 dump, we noticed that the Wikimedia Dumps website does not contain this date dump
for the "bbc", "dga", nor "zgh" Wikipedias. We have reported the issue to the Wikimedia Phabricator: https://phabricator.wikimedia.org/T351761
