Adjust default MT services for pairs where the default is not the most used
Closed, ResolvedPublic1 Estimated Story Points

Description

Content translation integrates different translation services. A recent analysis (T303812) shows that for some language pairs the default service provided is not the one used the most. This means that most users change the default, indicating their preference for a different one (which can be an indicator of higher MT quality). In those cases we may want to adjust the default service.

The proposed changes are:

  • ru → be to use Yandex
  • pt → gl to use Google
  • en → es to use Google (this adjustment is also covered in T309169)
  • {en, fr, it} → ca to use Google.
  • {ca, en, es, fr, gl} → eu to use Elia

Pginer-WMF moved this task from Needs Triage to MT on the ContentTranslation board.

There was a similar request from Basque Wikipedia editors to have Elia as the default.
The data above shows that Elia is used for 43% of the translations to Basque, while Google is used for 57% (with the advantage of being provided as the default). So it seems that data shows Eli as a possibly preferred option to be the default.

@UOzurumba will check for which source languages makes sense to do the adjustment from those supported by Elia: {ca, en, es, fr, gl} → eu?
