To answer many people on the thread, it seems it’s the Leiden University’s Ranking. It was well circulated in my country for the top university here being in the top three outside China.

Paraphrasing what I read from a few local news outlets, it seems that they use bibliometric data (churning out articles, citations and such), as well as some diversity metrics, such as women in academia favoring a higher ranking than those unis that have worse numbers.

I did not check the method for myself, just because I like the result and didn’t bother to check further.
