The content translation tool makes it easier for Wikipedia editors to translate articles. It has been used to create more than 280,000 translations across Wikipedias in dozens of languages.

For some languages, the tool automatically translates articles for editors, who then can improve the content. These automatic translations are provided by machine translation services. You may have used some of these services from your browser or as translation apps when trying to make sense of a foreign sign, translating a social media comment, or trying to access a website that is not available in your language.

Machine translation services use software to automatically translate a text into another language, in this complex process they may use information about the language structure and vocabulary, a large set of examples of sentences in those languages, machine learning techniques or some combination of these and other approaches.

We recently added support to automatically translate articles from Spanish to Basque using Matxin, an open source translation engine created at the University of the Basque Country. We believe that the integration of Matxin will increase the quality and quantity of material available in the Basque Wikipedia: before Matxin was integrated, about one thousand articles were translated into Basque with the content translation tool. Half of these articles were translated from into Basque from Spanish. Now that the tool is available, editors can automatically translate material from Spanish into Basque using Matxin, which will make it easier for them to add new material to the Basque Wikipedia.

How we partnered with the Matxin team

The content translation tool was designed so that new extensions could be integrated as they became available, allowing the platform to support more automatic translations between languages.

The Matxin integration is one such example, and has been a great partnership between the Matxin team and the Language team from the Wikimedia Foundation. The Matxin team from the University of the Basque Country and Elhuyar Foundation developed a client to integrate their machine translation service in content translation, and contacted the Language team for further guidance. After several iterations of code review, legal review of licenses, and testing, the client was ready for deployment. With this integration, the constant effort of the Matxin team to improve their translation service will be immediately available to Wikipedia editors.

The integration of Matxin respects user privacy and content license: no user data is shared with external services, and the translated content is generated under a free license to enable its integration into Wikipedia. In addition, the results of the translations obtained and the corrections that users made are exposed publicly through our APIs for researchers and developers working on improving these translation services or creating new ones. You can learn more details about the integration of Matxin in content translation.

We are excited by this partnership, and by the idea that our translation platform can be improved and expanded by local communities. Improving translation tools such as content translation helps reduce the language barriers for users to access vital knowledge.

We are always open to collaborations with others in the machine translation community. If you are working on a translation service, you can check the documentation on how to integrate new translation services into content translation and contact us on the project’s discussion page.

Offline-Pedia converts old televisions into Wikipedia readers

There are villages in the Ecuadorian Andes that are so small you cannot find them on a map. Cajas Juridica is one such place, located just 13km north of the equator. But two engineering students, Joshua Salazar and Jorge Vega, and the staff of Yachay Tech University have figured out a way to give discarded….

Meet the scientist working to increase the number of underrepresented scientists and engineers on Wikipedia

By day, Dr. Jess Wade is a physicist best known for her work on “polymer-based, circularly polarising, light-emitting diodes.” But in the evenings (and on the weekends, and as other time permits) Dr. Wade is a strong advocate for increasing diversity and inclusion in STEM subjects, speaking at conferences and starting a campaign on Wikipedia to promote more early-career women….

New interaction timeline improves investigation of harassment cases

The new interaction timeline tool is a way to look at two contributors’ editing history—where they have interacted, when, and how often. This can help add clarity when reviewing reports of harassment and abuse, and takes some of the burden off both the people reviewing problems, and the people reporting them.
