1 Introduction
</SectionTitle>
    <Paragraph position="0"> This paper presents a tripartite model of dialogue in which intentions are modeled on three levels: the domain level (with domain goals such as traveling by train), the problem-solving level (with plan-construction goals such as instantiating a parameter in a plan), and the discourse level (with communicative goals such as ezpressing surprise).</Paragraph>
    <Paragraph position="1"> Our process model has three major advantages over previous approaches: 1) it provides a better representation of user intentions than previous models and allows the nuances of different kinds of goals and processing to be captured at each level; 27 it enables the incremental recognition of commumcatire goals that cannot be recognized from a single utterance alone; and 3) it differentiates between illocutionary effects and desired perlocutionary effects, and thus can account for the failure of an inform act to change a heater's beliefs\[Per90\] ~.</Paragraph>
