Producing Dialog at MERL: Problems in Generation Engineering

David D. McDonald

It is not necessary to have a full-scale NLG system in a dialog system that uses fixed-text templates for its responses to significantly improve in their cohesion and fluency. Given a flexible system, fixed phrases can be transparently replaced with pronouns or definite references.
