I think we could ask either Yago or BabelNet or both whether they would be receptive to release their mappings under a CC0 license, so it can be integrated into Wikidata. What I wonder is, if they do that, whether we wanted to have that data or not.

One problem with BabelNet is that its licence is restrictive, being
the Attribution-NonCommercial-ShareAlike 3.0 Unported (CC BY-NC-SA 3.0)
license.  Downloading BabelNet is even more restrictive, requiring also
working at a research institution.

Yago
http://www.mpi-inf.mpg.de/departments/databases-and-information-systems/research/yago-naga/yago/
, which has the less restrictive license Attribution 3.0 Unported (CC BY 3.0),
has links between Wikipedia categories and Wordnet.  Unfortunately, it does
not carry these links through to regular Wikipedia pages.   I've been toying
with making this last connection, which would be easy for those categories
that a linked to Wikipedia page.

PS:  Strangely the Yago logo has a non-commercial license.  I don't know why
this was done.
