Recommendations for translation are currently built around the article title in the source language - for example:
Is it possible to have the system based around the Wikidata "Q" number for the chosen topic? This allows for greater flexibility, for example, if you know the target language but there are several potential source languages that the end-user can chose to translate from.
So, not " 'Mona Lisa' on en.wp " but instead "Q12418".
I feel that this would make the system more robust, and be relevant to many potential use-cases (though I can't think of them specifically!)
