## Description
Official Wikimedia wikis are released under a CC BY-SA license.
We downloaded the official database dumps from March 2025 of the English-language wikis that are directly managed by the Wikimedia foundation.
These database dumps include the wikitext—Mediawiki’s custom markup language—for each page as well as talk pages, where editors discuss changes made for a page.
We only use the most recent version of each page.
We converted wikitext to plain text using [wtf_wikipedia](https://github.com/spencermountain/wtf_wikipedia) after light adjustments in formatting to avoid errors in section ordering caused by a bug.
Before parsing, we converted wikitext math into LATEX math using our custom code.
Finally, any remaining HTML tags were removed via regexes.
This collection includes data from the following Wikimedia wikis:
[Wikipedia](https://wikipedia.org),
[Wikinews](https://wikinews.org),
[Wikibooks](https://wikibooks.org),
[Wikiquote](https://wikiquote.org),
[Wikisource](https://wikisource.org),
[Wikiversity](https://wikiversity.org),
[Wikivoyage](https://wikivoyage.org),
and [Wiktionary](https://wiktionary.org).

## License Issues
While we aim to produce datasets with completely accurate licensing information, license laundering and inaccurate metadata can cause us to erroneously assign the incorrect license to some documents (for further discussion of this limitation, please see [our paper](https://huggingface.co/papers/2506.05209)). If you believe you have found an instance of incorrect licensing in this dataset, please [start a discussion](https://github.com/r-three/common-pile/discussions/new) on this repository.

## Other Versions
This is the "raw" version of the Wikimedia dataset.
If you are looking for the filtered version used to train [Comma v0.1](https://huggingface.co/common-pile/comma-v0.1), you can find it [here](https://huggingface.co/datasets/common-pile/wikimedia_filtered).

# 维基媒体（Wikimedia）

## 描述
官方维基媒体旗下维基站点均采用知识共享署名-相同方式共享（CC BY-SA）许可协议发布。
我们采集了由维基媒体基金会直接运营的英语维基站点2025年3月发布的官方数据库转储文件。
这些数据库转储文件包含所有页面以及讨论页的维基文本（wikitext）——媒体Wiki（MediaWiki）自定义标记语言——，其中讨论页用于编辑者讨论针对特定页面的修改方案。
我们仅保留每个页面的最新版本。
在对格式进行轻量调整以规避因某一漏洞导致的章节排序错误后，我们借助[wtf_wikipedia](https://github.com/spencermountain/wtf_wikipedia)工具将维基文本转换为纯文本格式。
在解析前，我们通过自研代码将维基文本中的数学公式转换为LATEX格式的数学表达式。
最后，我们通过正则表达式移除了所有残留的HTML标签。
本数据集涵盖以下维基媒体旗下的维基站点：
[维基百科（Wikipedia）](https://wikipedia.org)、
[维基新闻（Wikinews）](https://wikinews.org)、
[维基教科书（Wikibooks）](https://wikibooks.org)、
[维基语录（Wikiquote）](https://wikiquote.org)、
[维基文库（Wikisource）](https://wikisource.org)、
[维基大学（Wikiversity）](https://wikiversity.org)、
[维基旅行（Wikivoyage）](https://wikivoyage.org)
以及[维基词典（Wiktionary）](https://wiktionary.org)。
