We have a system that can learn to translate better if we know where the problems are. In the past, there was no way to tell us about problem translations. Now there is. Next time you see a sentence that makes you go "hmmm," just hover over it to display the original text tooltip and click the "Suggest a better translation" link. Tell us what it should have said, and we'll use your suggestion to improve translation quality in future updates to our service.
This feature is available when you use one of the language translation pairs developed by our research group:
* English to/from Arabic
* English to/from Chinese (Simplified/Traditional)
* English to/from Russian
* Chinese (Simplified) to/from Chinese (Traditional)
One thing that really stands out (at least to me) is the choice of languages you can help translate.
