6 Confusions and Future Work
</SectionTitle>
    <Paragraph position="0"> We have presented a plan-based framework for generating responses in a collaborative environment. Our framework improves upon previous ones in that, 1) it captures co-operative responses as a part of collaboration, 2) it is capable of initiating negotiation subdialogues to determine what actions should be added to the shared plan, 3) the correction process, instead of merely pointing out problematic plans/goals to the user, modifies the plan into its most specific form accepted by both participants, and 4) the evaluation/correction process operates at a meta-level which keeps the negotiation subdialogue separate from the original dialogue model, while allowing the same plan-inference mechanism to be used at both levels.</Paragraph>
    <Paragraph position="1"> We intend to enhance our evaluator so that it also recognizes sub-optimal solutions and can suggest better alternatives. We will also study the goal selector's task when the user's plan/goal is well-formed/feasible.</Paragraph>
    <Paragraph position="2"> This includes identifying a set of intentional goals and a strategy for the goal selector to choose amongst them.</Paragraph>
    <Paragraph position="3"> Furthermore, we need to develop the intentional planner which constructs a plan to achieve the posted goal, and a discourse realizer to generate natural language text.</Paragraph>
