We have been working on such a type guesser at Melbourne which uses the
tokeniser supplied with the relevant grammar (experiments so far have focused
on the ERG and JaCY). The main person behind this is currently finishing up
his PhD, so don't ask for a cleaned-up version of the code until the dust has
settled a bit, but the hope is we'll be able to release everything as part of
the DELPH-IN resource package. Otherwise, Yi Zhang has a mature type-guessing
solution for unknown words which is properly integrated with PET, so you might
like to talk to him.
