# Wikiteam

## Description
There are many wikis on the internet that are not managed by the Wikimedia Foundation, but do use their MediaWiki software to power their wiki. Many of these wikis have been archived by Wikiteam, a collection of volunteers that create unofficial database dumps of wikis and upload them to the Internet Archive. We download all dumps made by Wikiteam when the metadata indicates the wiki was licensed under CC BY, CC BY-SA, or released into the public domain on the Internet Archive as of September of 2024. This results in downloading approximately 330,000 wikis. When multiple dumps of the same wiki exist, we use the most recent dump. 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. After preprocessing, we removed documents from wikis that appeared to contain large amounts of license laundering, e.g. those that were collections of song lyrics or transcripts. Per-document license information is available in the `license` entry of the `metadata` field of each example. Code for collecting, processing, and preparing this dataset is available in the [common-pile GitHub repo](https://github.com/r-three/common-pile).

## 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 "filtered" version of the Wikiteam dataset. If you are looking for the raw version, you can find it [here](https://huggingface.co/datasets/common-pile/wikiteam_raw).

# Wikiteam

## 数据集描述
互联网上存在大量并非由维基媒体基金会（Wikimedia Foundation）托管，但采用其MediaWiki（媒体维基）软件搭建的维基站点。Wikiteam是一支志愿者团队，负责为这些维基站点制作非官方的数据库备份，并将其上传至互联网档案馆（Internet Archive），其中多数站点已被该团队归档。我们于2024年9月时，从互联网档案馆下载了所有元数据（metadata）显示采用CC BY（知识共享署名许可）、CC BY-SA（知识共享署名-相同方式共享许可）或已进入公有领域的Wikiteam备份，总计约33万个维基站点。若同一维基站点存在多份备份，我们将选用最新版本。

在修复了一处会导致章节顺序错误的格式问题后，我们使用[wtf_wikipedia](https://github.com/spencermountain/wtf_wikipedia)工具将维基标记语言（wikitext）转换为纯文本。解析前，我们通过自定义代码将维基标记语言中的数学公式转换为LaTeX数学格式。最后，通过正则表达式移除所有残留的HTML标签。

预处理完成后，我们剔除了疑似存在大量许可滥用（如包含大量歌词或转录文本集合）的维基站点中的文档。每个样本的元数据字段中的`license`项均包含单文档的许可信息。

本数据集的收集、处理与整理代码可在[common-pile GitHub仓库](https://github.com/r-three/common-pile)中获取。

## 许可相关问题
尽管我们力求生成许可信息完全准确的数据集，但许可滥用与元数据不准确可能导致我们为部分文档错误分配了许可协议（关于该局限性的进一步讨论，请参阅[我们的论文](https://huggingface.co/papers/2506.05209)）。若您发现本数据集存在许可信息错误的情况，请在本仓库发起[讨论](https://github.com/r-three/common-pile/discussions/new)。
