Sounds very interesting. I'll make sure to look into it,
once it's available.

Thanks for the hint! I'll do that.

Regarding Ulrich Schäfer's reply:

I'll have a look at FSR preprocessing in the PET. If it does
rely on POS tags for unknown words, that, of course, raises
the question where to get POS tags for the correct tokenization.
But we've discussed that in some depth now anyway.

Sentence-splitting in the PET: Yes, that would be a bad idea,
indeed. Once Ann mentioned there were *grammar* rules for
sentence and token splitting, that became clear to me.

Having "manually preprocessed" a small subset of my data to play
around with, I now definitely see your point about named entities.
These actually seemed to cause much more OOVs on my dataset (from
the RTE-3 callenge) than dictionary words that weren't in the ERG
