Content translation/Machine Translation/LingoCloud
Machine translation support for Content Translation has now been further extended with the inclusion of LingoCloud machine translation system. This is in addition to Apertium, Yandex and Youdao, and Matxin machine translation (MT) systems that are already available for users of Content Translation.
LingoCloud is provided by Beijing ColorfulClouds Technology Co., Ltd, providing machine translation services between English, Chinese and Japanese. Various teams inside Wikimedia Foundation have collaborated with the LingoCloud team to work out an agreement that will allow the use of the tool without compromising Wikipedia's policy of attribution of rights, privacy of our users, and brand representation. Please find more details of the agreement below.

- No personal information is sent to LingoCloud. The MT system will be accessed via an API key. Article content (freely licensed) is sent to the LingoCloud server from Wikimedia Foundation servers. No direct communication is happening between the user and external services and no personal information (IP, username) is sent to the LingoCloud service. The client contacting LingoCloud is open source and you can check it here. No part of LingoCloud’s service or code will be part of Wikimedia infrastructure or Content Translation codebase. Please also see a diagram of this technical setup at the end of the section.
- Information is returned from LingoCloud under a free license. When LingoCloud is used, a translated version of Wikipedia content under a free license is obtained. Users can modify it and publish it as part of Wikipedia without conflicts with existing policies. The resulting content translated by LingoCloud and the user modifications will be available under the same license that is used for the rest of the articles in Wikipedia.
- Benefits the wider open source translation community. Translations obtained from LingoCloud and user modifications will be publicly available. The post-edited translations are of special interest for the translation research community (including the LingoCloud team) who can use this resource to create new translation services to support languages for which open source machine translation is not available yet. This will help developers create and improve machine translation systems.
- Users can disable it. Automatic translation is an optional tool in Content Translation. Users have an option to disable it if they don't find it useful for some reason. Although many Content Translation users have requested for this translation service, each individual user eventually decides whether they would like to use it or not.
Summary of our agreement with LingoCloud
- To allow for free use of their machine translation API key to the Wikimedia Foundation to allow volunteers on Wikimedia sites to translate articles and supporting 10 million characters of translation content per day.
Wikimedia Foundation's obligations
- To provide the volunteer-edited versions of the text translated by the translation tool so that LingoCloud can improve their tool
- No personal data of translators will be shared.
- Just the original content to translate, its language, and translation target language will be sent in the request to LingoCloud.
- The translations published by translators, with or without the help of machine translation services, will be provided in the form of parallel corpora by the Content Translation APIs. These APIs will be developed incrementally and results will be freely available for everyone, not just LingoCloud.
- All content will remain licensed under CC BY-SA 3.0
- LingoCloud is not requiring any "branding" on Wikimedia Sites outside of listing LingoCloud as a translation tool option in the translation interface drop-down menu
- There is no exchange of personal information of volunteers
- The agreement is limited to 1 year, at which time we can reevaluate our needs
- We are free to terminate the agreement for any reason, at any time (with 30 days notice)
- Agreement is governed by US law
Questions about this service
We have addressed some immediate questions about LingoCloud in this section. This is also available in the Content Translation FAQ page.
What languages are being handled by LingoCloud? Are there plans to add more?
LingoCloud can be used to translate from English to Chinese, and Chinese to Japanese, and Japanese to Chinese. As more languages are added to the service by the developers of the LingoCloud team, we will include them.
How is using LingoCloud different than using other machine translation services?
As a user of Content Translation you will not feel any difference on the translation interface as LingoCloud will display the translated content in the same way other services currently do for the supported language pairs.
How is the machine translation being done if I choose LingoCloud?
LingoCloud provides an API key that allows websites and other services to use their translation system. Content Translation also uses that unique API key to access LingoCloud. When a user starts translating an article, the HTML content of each section of the source article is sent to LingoCloud and a translated version is obtained and displayed on the respective translation column of Content Translation. Links and references are adapted as usual and users can modify the content as required.
This process continues for all the sections of the article being translated. For better performance, the translations for consecutive sections are pre-fetched. The user can save the unpublished translation (to work on it again at a later time) or publish the article in the usual manner. The article is published on Wikipedia like any other normal article with appropriate attribution and licenses.
LingoCloud is not based on open source software. Why are we using it?
Content Translation evolved from a long-standing need to bridge the gap in the amount of content between Wikipedias in different languages. Like all other software used on Wikimedia sites, Content Translation is also open source. In this particular case as well, we are using an open source client to interact with the external service and import freely licensed content in order to help users expand our free knowledge.
Similar to Yandex, and Youdao, for LingoCloud’s machine translation system we are not adding any proprietary software in the Content Translation code, or on the Wikimedia websites and servers. The service is free of charge and available for everyone.
Only the freely available Wikipedia article content (in segments) is sent to the LingoCloud service and the obtained translated content is also freely usable on Wikipedia pages. The translated content can be modified by users and this data also maintains its free license and is available publicly through the Content Translation API. This is a valuable resource made available for the community to develop open source translation services for those languages where they don't exist yet.
From user feedback we have seen that machine translation support is really helpful for users and we want to support all languages in the best way. Guided by the principles of Wikimedia Foundation's resolution to support free and open source software, we will prioritise the integration of open source services whenever they are available for a language. Apertium has been a critical part of Content Translation since its inception, and currently provides machine translations for nearly 70 of the numerous possible language combination that Wikipedia can support. Adding Yandex, Youdao and Maxtin has helped a large group of users of nearly 70 more languages, who were unable to use this facility before with Content Translation.
Should I be worried about my personal information when using LingoCloud?
Irrespective of the service being used, you can be assured that only Wikipedia content from existing articles is sent and only freely licensed content will be added back to the translation. No personal information is sent and communication with those services happen at the server side, so they are isolated from the user device. Please refer to this diagram for more details.
What if LingoCloud is the only machine translation tool available and I don't want to use it?
Machine Translation is an optional feature in Content Translation that you can easily disable at will. If more machine translation systems are added for your languages, you can choose to enable MT again and select the MT service of your choice.
Will the content translated by LingoCloud be free for use in Wikipedia?
Yes. The content received from LingoCloud is otherwise freely available on the web translation platform. Content Translation receives it via an API key to make it seamlessly available on the translation interface. This content can be modified by the users (if necessary) and used in other Wikipedia articles under free licenses.
Can this content be used for improving machine translation systems in general?
Yes. Translations made in Content Translation are saved in our database. This information will be made publicly available for anyone to use as translation examples to improve their translation services (from University research groups, open source projects to commercial companies, anyone!). The content can be accessed via the Content Translation API. Please note, only information related to translated text is publicly available. This includes – source and translated text, source and target language information and an identifier for the segment of text.
