CopyPatrolは、著作権違反の恐れがあるとマークされた最近のウィキペディアの編集内容を見ることを可能にするツールです。CopyPatrolはウィキメディア財団のCommunity Techチームによって開発され、維持されています。


このツールは現在、英語、アラビア語、フランス語、スペイン語、シンプル英語、および中国語のウィキペディアプロジェクトをサポートしています。他の言語のサポートに関する協議は、タスク T141379を参照してください。



CopyPatrolを使用するには、まずログインする必要があります。CopyPatrolに行き、右上にある「ログイン」をクリックしてください。 すでにウィキメディアアカウントにログインしている場合は、ページが更新され、ログインボタンの代わりに利用者名が表示されます。



  • Compare panel – 編集時点の特定版を開き、指定のソースと比較します。 ほとんどの場合、コンテンツが直接、転写されたものかどうか判断材料として充分で、また CopyPatrol インターフェースだけを使い、当該の編集が引用などであり継承を正しく示しているか、検証できます。
  • Percentages – 編集時点でソースと一致する単語数を示します。高率の場合は、編集内容の大部分を指定のソースから転写したことを示します。
  • iThenticate report – もし比較ツールが百分率または単語数で称号結果を示さない場合には、ソースがその後に改変されたと考えられます(たとえばニュース配信など)。iThenticate 報告機能を使い、編集時点のソースの状態を調べることができます。
  • WikiProjects – If you are interested in tracking violations for one or more WikiProjects, you can do so using the WikiProject search at the top. You can also click on a WikiProject bubble for any record in the interface and that will show you all open cases for that WikiProject.
  • Filters – As a reviewer, you'll want to keep this set to "Open cases", but for historical reference you can see all the reviewed cases, and search by username or page title.
  • Drafts – You can use the Draft checkbox to show only potential violations in the Draft namespace, if it exists on your wiki. This is especially helpful for editors who work at Articles for Creation, as you may be able to quickly reduce the backlog by identifying obvious declines that are copyright violations.
  • Leaderboard – This lets you see the top reviewers in the past week, month and all time. Help review more cases to achieve your place on the leaderboard! One exists for each language.
  • Permalinks - Allow the possibility to share directly to an entry by a direct link, like copypatrol.wmcloud.org/fr?id=25727. This URL would show only the entry specified by the ID.


Once you've verified the content matches the source, check the license of the source and ensure it is compatible with Wikipedia. If no license is provided, you should assume it is not freely licensed.


Sometimes edits may appear to be copyright violations when they are not. These are called false positives and can be in various forms:

  • Properly attributed copying of licensed or public domain material
  • Properly attributed quotations
  • Restoring material from a previous revision of the same article
  • Addition of lists, timelines, math formulas and bibliographies
  • Moving material around within the same article

Please consider these possibilities when reviewing edits.

Backwards copies

Note also the possibility of backwards copies, where the source appeared to copy content from Wikipedia. This is not necessarily a false positive, and may mean the editor copied content within Wikipedia. In this case, the edit should be properly attributed, generally with an edit summary "content copied from ​[[article name]]​". If no attribution is given, it can be rectified with a dummy edit stating the previously added content was copied from another article, among other methods.


The ignore lists are shared between all the wikis that CopyPatrol supports.

  • URL ignore list – URLs listed here will be removed from copy and paste concerns
  • User ignore list – Filters out trusted users who frequently show up as false positives



  • Assess the edit and determine whether or not a copyright violation has occurred. If it is a copyright violation, remove the copyrighted content or tag it for speedy deletion with {{db-g12|url=sourceurl}} if it is a new page that is predominantly a violation.
  • Notify the editor of copyright policy using {{uw-copyright}}{{uw-copyright-new}}, or a personalized message. If you discover unattributed copying within Wikipedia, the editor should be notified of our attribution requirement using the template {{uw-copying}}. If you discover unattributed copying from public domain materials, notify the user using the template {{uw-plagiarism}}. All of these templates need to be substituted. Please consider adding the required attribution to the article yourself, as a new editor is unlikely to know how to do it.
  • If you are an administrator, please consider revision deleting the related diffs under criterion RD1 if they qualify. If you are not an administrator you can request revision deletion using {{copyvio-revdel}}.
  • Finally, please update the status in the interface. If you fixed the problem, tagged the page for revision deletion, or tagged the page for deletion as a copyright violation, mark it as "Page fixed". (Please consider watch-listing pages you nominate for deletion or tag for revision deletion to ensure they get resolved to your satisfaction.) If you find the item is a false positive or if the page has already been deleted for reasons other than copyright violation, mark it as "No action needed".

Requesting new wikis

If you would like your wiki to be added, please first make sure iThenticate supports your language. Look for the "Which international languages does iThenticate have content for in its database?" section in the "General" section of the FAQ.

Then please get community support from your wiki. If the community agrees, create a Phabricator task linking to the discussion. There should be evidence that the community will regularly make use of CopyPatrol.
