Regarding the attributions, when post-editing, attribution does not need to be displayed. As far as I understand,
post-editing as referred in the
FAQ page to Wikipedia, is a review process perform a human to go through the machine translations. The process does not guarantee any modification of the machine translations, but it is still a review/post-editing process.
If after the review process, the machine translations remains as it is, are we required to display the attributions?
