Does anyone know of a simple way (e.g. some clever bit of metadata) to find wikipedia articles in other languages on the same topic as a given English wikipedia page?
It looks like the big cluster refers to computing, as it contains the english "Hacker (Computing)" and the german "Hacker". The small one should be the disambiguation cluster: "Hacker" (which is a disambiguation page) and "Hacker (Begriffsklärung)", respectively.
Hacker has probably an unambiguous meaning in most languages.
