C'mon, even mathematicians have common sense, sometimes :)  A
mathematician would simply say that the relation of being a close friend
is not transitive.  Thus, if the interlanguage links were to mean
"roughly equivalent", then it wouldn't be transitive and it would be
unsound to perform a transitive closure.  In other words, if the links
are interpreted as "roughly equivalent" then you're absolutely right: it
doesn't make sense to do the analysis that I've done.

The point is, according to the policies (at least the way I interpret
them) and according to some bot authors and probably according to a
large share of users, the interlanguage links do represent equivalence. See:

http://en.wikipedia.org/wiki/Help:Interlanguage_links
http://meta.wikimedia.org/wiki/Help:Interwiki_linking#Interlanguage_link

Besides, note that multiple interlanguage links from a given page to a
given language edition are discouraged (although partially supported by
the MediaWiki engine).  If the ILLs were to mean "similarity", then
multiple links to the same language wouldn't have been discouraged (an
article can be "similar" or "roughly equivalent" to more than one
article in another language edition).

Summing up, IMHO the intended meaning of ILLs is "equivalence", and it's
supported by four arguments (two links, "discouraged multiple ILLs"
argument, and bots).

Another thing is that some of the ILLs are clearly incorrect even using
the relaxed interpretation (like June 26 -> June 27, Rick Ankiel ->
Japanese language, Tap (valve) -> Griffin, listed in the other post).
