I agree with Fran that improving the current Catalan tagger may get a bit
hard. However, the apertium-cat tagger performs a bit worse than the "best"
CAT tagger we had before (apertium-es-ca.ca), mainly due to the addition of
a lot of verbal forms. So a retrain (or maybe a few CG rules) could help
not only eng-cat, but other language pairs as well.

I know Wikipedian editors are using currently the fra-cat language pair,
which doesn't perform that well either (Hèctor has been doing some
improvements to it)

That would make a huge difference, even more if coverage + WER is computed
agains the Wikipedia, where there are a lot of proper names.

+1. Clarity on what will be used to validate the improvements implemented
is needed.

+1 on focusing on eng->cat, as it's what makes more sense for
dissemination. However, having something a bit "better" than the current
cat-eng for assimilation purposes would also benefit.
