  This short position paper is intended to provide a critique of current
approaches to dialogue, as well as a roadmap for collaborative dialogue
research. It is unapologetically opinionated, but informed by 40 years of
dialogue re-search. No attempt is made to be comprehensive. The paper will
discuss current research into building so-called "chatbots", slot-filling
dialogue systems, and plan-based dialogue systems. For further discussion of
some of these issues, please see (Allen et al., in press).
