But basically: treating interwiki links as a 1-1 relationship even from one wiki to another is horribly unreliable, and assuming you can go from wiki A to wiki B to wiki C with interwiki links is just not doable reliably with robots.
If you only look at language-links that got *both* ways, you get a decent 1-to-1 mapping. I used this as part of my thesis, and wrote a short paper about it: http://brightbyte.de/repos/papers/2008/LangLinks-paper.pdf.
I can also recommend the studies of Rainer Hammwöhner about Wikipedia, especially "Interlingual Aspects if Wikipedia’s Quality" http://mitiq.mit.edu/iciq/PDF/INTERLINGUAL%20ASPECTS%20OF%20WIKIPEDIAS%20QUALITY.pdf, which studies the quality of language links and the categtory system, among other things.
