Compact語言鏈接功能是通用語言選擇器(ULS)的一部分 - 提供語言選擇和訪問各種語言相關設置的擴展。 自2013年以來,ULS一直在所有維基媒體wiki上使用。自2014年在 OPW項目中創建以來,緊湊語言鏈接作為單獨的beta功能提供。




可以使用“首選項”->“外觀”->“語言”下的設置啟用和禁用壓縮語言鏈接。 也可以使用Global preferencesSpecial:GlobalPreferences)在所有wiki中禁用它。 目前,該設置可在幾個階段為所有維基媒體wiki提供。

通過緊湊的語言鏈接,首先顯示用戶的相關語言的簡短列表。 此選擇基於您之前的語言選擇,瀏覽器設置,您的位置以及您正在閱讀的文章的屬性。 您可以在此常見問題解答中閱讀有關此選擇的更多信息:如何確定在初始緊湊列表中向我顯示哪些語言?


在列表的底部將顯示頁面所存在的語言數量。 單擊它將顯示其餘語言。 它可以用任何語言的語言名稱進行搜索,並且可以處理拼寫錯誤。 也支持按語言代碼搜索。





Many projects have global or personal customizations for the language list. For example, several Wikipedias asked to put certain languages always at the top, some showed certain languages in a bold font, some had gadgets that prioritize languages according to user's choice, etc.

Ideas for a global feature of this kind were coming up at least since 2010.


Simply click them in the panel that opens when you click the "X more" button.

Every time you click a language, it will be automatically added to the list of languages that will be shown in the initial compact list.

You can also add the languages that you want to your browser settings.


You are not supposed to see any change in the interlanguage area. You will, however, see that Compact Language Links does no longer appear as a feature under the Beta features section. Instead, you will see a new preference setting under Preferences -> Appearance -> Languages, where the checkbox 使用紧凑的语言列表,它包含与您有关的语言。 will be selected.

Please go to Preferences -> Appearance and scroll down to the Languages section. Here you can see a checkbox which says 使用紧凑的语言列表,它包含与您有关的语言。 Deselect this checkbox and save the preferences. (See image)


Between 7 and 9 languages are generally shown in the initial compact list. The size of the list was based on two factors.

  1. Making enough room for the number of languages people may need. During our research on different language-related projects we have asked participants about the languages they speak and 9 was a limit very rarely exceeded. For example, for 内容翻译 , from 187 responses 85% of the users spoke 4 languages or less. This also seems consistent with research on multilingual editors.
  2. The list had to be short enough to be processed quickly and easily, and communicate the idea that this article is available in other languages. While a person's working memory can be different from human to human, "7 ± 2" is a a common design guideline that suggests we may be providing a short enough list for people to process.



Even if the needed language doesn't appear in the initial list, it is easier to find it using the panel and the search box than to find it in the long list with all the languages.

After the language is clicked once, it will always be shown with the highest priority in the initial short list. Most users access a small set of languages repeatedly, and the long list requires that they search for them every single time, so having the frequent languages appear automatically saves a lot of time.

Some users find it convenient to search for the language they need using the "Find in page" function that can be found in many browsers, but various estimates put the number of web users who are aware of this feature at about 10—20%.[1] In addition, the "Find in page" feature can match similar words in the content, it is not able to correct for typos or consider alternative ways to refer to a language including ISO codes, different scripts, etc. All these capabilities are provided by the search box in the pop-up language selection panel.


The main factor for choosing the languages are the selections of the user. This means that you can select the languages you want the most by simply clicking on them. If you are interested in reading the article in Japanese, once you select it, a link to the Japanese language will be surfaced for easier access next time.

The first time, due to the lack of previous choices by yourself, the language selection is based on other factors. Here's the complete and ordered list of the criteria according to which the languages for the initial compact list are selected:

  1. The languages on which the user clicked in the language selector panel previously.
  2. 您浏览器的语言。您可以自己设置
  3. The languages defined in your Babel box.
  4. Geographic information, which is based on the CLDR Territory-Language information. If the information for your country there is not precise, you can contribute to it.
  5. Languages that are used in the page's content with the lang attribute. This attribute is added by various "lang" templates in Wikipedias in many languages, when mentioning the name of a foreign person or place—for example, in the English Wikipedia article Prague, the Czech name of the city ("Praha") is mentioned using the {{lang-cs}} template. Using any HTML element with the lang attribute would work as well (for example, <span lang="cs">Praha</span>).
  6. 特色条目。
  7. 如果上述方法没有找到9种与读者相关的语言,一些存在对应条目的世界上常用的语言会被显示:中文、英文、法文、印尼文,等等。


Please check that you are logged in and that you are using the {{#babel|}} notation on your user page. See the documentation of the 扩展程序:Babel extension. Many wikis have an old template that shows a Babel box, but these templates are implemented differently in each of them and cannot be used by Compact Language Links. The {{#babel|}} notation allows adding a Babel box in a uniform way across all wikis, and has a similar appearance in all of them.

If you have a Babel box using the {{#babel|}} notation on your user page and you still don't see the languages that you specified in it in the initial compact language list, this may be a software bug. Please report it at the project talk page.

Technical notes:

  • The BabelMainCategory variable must be set up for your wiki in the InitialiseSettings.php file. It is already set up for many Wikimedia wikis, but not for all of them.
  • It is possible to wrap the {{#babel|}} notation in a template. This will work for Compact Language Links, too. This was done, for example, in the {{Babel}} template in Russian Wikipedia.

Will the languages that I have in a Babel box on my global user page appear in all the wikis?

Yes, they will appear in every wiki in which you don't have a local user page.

A local user page in a wiki will override your global Babel box.



The feature makes the best effort to auto-adapt itself to every user. The languages that are shown in the initial short list with the highest priority are taken from each user's previous choices, browser settings, and location. Some major world languages are shown only as the last fallback with the lowest priority.

In fact, thanks to respecting user preferences and using geolocation, it may make some smaller languages more prominent. Indeed, the clicks on links to all languages, especially the smaller ones, have grown since the feature was made available to anonymous users.


Links to all languages are available, but shown in the panel that appears when you click the "More" button, and our research shows that they are easier to find in this panel than in the long list. A user who clicks any language in the panel once, will see this language in the initial list after that.

We are watching the effect of this feature on the clicks on the links and on the traffic to all the projects. As of late 2017, over a year has already passed since the enabling of the feature on some major languages, such as Russian, Spanish and Chinese, and the number of clicks on the links, as well as the traffic to them have not gone down in any language.

Furthermore, in all the languages we have observed that the percent of people who entered the project in that language through interlanguage links from other languages has grown considerably, likely because the links are now easier to find. Here are the metrics from some languages. See also the full statistics for all the languages.

When the list of languages is long, the list is divided into sections by continent to allow easier visual perception. Otherwise the list would be too long. The division by continent is quite arbitrary; it simply allows a relatively balanced grouping. Division by linguistic family, for example, would be much less balanced, given that some linguistic groups include only one language, while others include several dozens.

Why aren't the languages sorted alphabetically?

Names of languages are written in different scripts. Hence, they cannot be sorted alphabetically.

After the initial grouping by continent, languages are further grouped by writing system, and inside each writing system they are sorted alphabetically.

In any case, design research has shown that users most frequently find the language that they need by using the search box and not by scrolling through the whole list.

Why are names of languages written in the languages themselves and not in the language of the wiki?

Because the primary users of interlanguages are readers who don't necessarily know how the name of their language is written in the language of the wiki.

It is possible to search for the language that you need in your language, or in any other, using the search box at the top of the panel.

Why does the search box and full languages list appear in a separate panel?

We considered that it (a) allowed the user to focus on their languages of interest (the initially visible provides enough room to include the number of languages most of our uses speak), and (b) it allowed us to provide advanced searching capabilities to facilitate the selection. Searching was the most common method for users to find their language during our research, and providing flexible search made it easier to support the cases where the language you are looking for was not in the initial list. You can search for a language based on the name in another languages, making typos or using the ISO codes. This allows searching even if you don't know how is the language's name is written in that language and if cannot type in that language on your keyboard. For example, English speakers are often unable to type in Japanese, but they can search for the Japanese language by typing "japanese" and they don't have to type "日本語".

Although the tool does not show initially all the interlanguage links, the access to them is provided through a "continuation" pattern where it is quite clear how to access to the rest of the languages. Our research confirmed that users were able to figure out how to find their language when it was not present in the initial list (something that they only need to do once at most). We are monitoring the volume of inter-language navigation to identify any potential issues.

What are the feature's success metrics?

The essential success metric is that the number of clicks on interlanguage links doesn't go down. Also, we hope to see that it becomes easier for readers to find languages that are relevant to them.

The developers have started recording the total number of clicks on interlanguage clicks to each language every day in May 2016, before the enabling of the feature to anonymous users started. We are seeing that they started to go up several weeks after the deployment. As of December 2016, the percent of clicks on interlanguage links out of the number of pageviews in each language is higher than it was in May 2016, in Wikipedia in all languages.

The average growth in clicks across all languages from June 2016 until June 2017 is 90%. The average growth in traffic that comes using interlanguages into all the languages in the same period is 85%.

You can find more information about this data at the page Universal Language Selector/Compact Language Links/metrics/data .

Is this related to adapting Wikimedia sites to mobile devices?

No. This is a redesign of the interlanguage links only on the desktop website.

The mobile website (MobileFrontend) has its own design for displaying and sorting interlanguage links.

It's possible that the mobile and the desktop design will be brought closer to each other in the future, but there is no concrete plan for this at the moment.


Your IP address is checked on the servers against a database which contains mappings from addresses to approximate locations. The results are stored in a cookie named GeoIP. ULS then reads this information and combines it with a list languages spoken in each country of the world, which is maintained by the CLDR project of the Unicode Consortium. The page wikitech:Geolocation has some more information about this.

It is said that geolocation is used to determine the language selection. How important is this criteria?

Geolocation is not perfect, but that is neither the only nor the primary information source. It is used in addition to more reliable sources: your previous selections and browser languages. In any case, our data relies on CLDR and it is expected to improve over time and we encourage users to ask for improvements on it.

With geolocation, are you not enforcing certain languages, which would be contrary to the mission of the Wikimedia Foundation?

Geolocation is only one of the mechanisms used to guess the user's language. In fact, if suggestions include the languages of a region this can bring more visibility to them than the old list.

Besides, emphasizing these languages makes smaller languages more prominent in the areas where they are spoken.

How can I make the data about the languages spoken in my country more precise?

We suggest all people to check the entries for their language in the CLDR Language-Territory database and to update it if needed. All languages, including constructed languages like Esperanto, can be added to it if there is data about the number of speakers in a given country.



Doesn't automatic personalization of the languages list make Wikimedia sites similar to commercial websites?

Wikimedia sites, like some other massively multilingual commercial sites, have to deal with the scalability in the number of languages it supports. Unlike it is with commercial websites, Wikimedia's purpose is not to optimize the profit by market, but to make it possible for every human being to share in the sum of all knowledge, and this includes access to all languages.

Compact Language Links are designed to make access to all languages not only possible, but easier. Unlike it is done on some commercial websites, no language is ever made inaccessible. Besides, the method for selecting the languages to show in the list is fully and openly documented right here on this page.


Most likely this happens because the display of the interlanguage links on the main page of your wiki is customized using the {{noexternallanglinks}} magic word. This was done in some Wikimedia wikis because there's a main page in all languages so the longest possible list of languages is shown, while the content of the main page itself is usually quite short.

With compact language links this customization shouldn't be needed on the main page, because the list is already compact and the languages are chosen automatically for each user, so the editors community in your wiki should consider removing it.

The language lists that you see in gray are being shown by 内容翻译 which is a beta feature that you have enabled. The languages in gray indicate that the article you are viewing is not present in those languages and can be translated via Content Translation by clicking on the gray links.
