The morphological and syntactic models documented here in a preliminary fashion were developed by Fumi Karahashi. Steve Tinney and Beatrice Santorini provided feedback on some aspects of the models.
These documents are the core PPCS manual, and will eventually be available in an indexed HTML version with the option of seeing syntax trees of all examples.
Questions about PPCS can be directed to Fumi Karahashi or Steve Tinney.
