Practically the only way to make the link for Maurizio Crozza is manually,
because there's no additional information to match on. If Wikipedia had a
link to MusicBrainz or Freebase had one of his movies and thus a link to
IMDB, the task might be possible to automate, but with the information
that's available it's basically an impossible task. One might imagine a
super sophisticated matching tool which was able Gialappa's
Band<http://it.wikipedia.org/wiki/Gialappa%27s_Band> references
from the WP article and the MusicBrainz album title, but I think that's a
real stretch.

It's not the data format that's the problem. You can't use an automated
guessing tool like Silk unless it's got at least a little bit of
information to base its guesses on. For topics which *do* have other
strong identifiers (IMDB, MusicBrainz, Library of Congress, VIAF, etc) or
additional information (e.g. birth date) it would be possible to do some
automatic matching, but I don't how many of your articles fall into that
category.
