apologies, i forgot one thing: unless working in a closed-vocabulary domain that is fully covered by the built-in ERG lexicon and its lightweight named entity recognition (numbers, dates, capitalized proper names, and such; recognized by surface patterns during token mapping), most use cases also enable unknown word instantiation based on PoS tags, by adding ‘-tagger’ to the cheap command line.  this option will make PET call out to a tagger, by default using the configuration in ‘pet/common.set’:

  taggers := tnt.
  tnt-command := "${LOGONROOT}/bin/tnt".
  tnt-arguments := "-v0 -z100 ${LOGONROOT}/coli/tnt/models/wsj -".

looking at the excessive use of comments in the above file, i realize that too might have some documentation value.

best, oe
