ABSTRACT
</SectionTitle>
    <Paragraph position="0"> The goal of thls work is the enrichment of human-machlne mteractIons in a natural language envlronment. 1 We want to provide a framework less restrictive than earlier ones by allowing a speaker leeway tn forming an utterance about a task and in determining the conversational vehicle to deliver it, A speaker and listener cannot be assured to have the same beliefs, contexts, backgrounds or goals at each point in a conversation. As a result, dlfflcultles and mistakes arise when a listener interprets a speakers utterance. These mistakes can lead to various kinds of mlsunderstandlngs between speaker and hstener.</Paragraph>
    <Paragraph position="1"> including reference failures or failure to understand the speaker's mtentlon. We call these mtsunderstandlngs mlscommunmatlon Such m~stakes constitute a klnd of &amp;quot;ill-formed&amp;quot; input that can slow down end possibly break down communication. Our goal ~s to recognize and Isolate such mlscommunlcattons and circumvent them. Thls paper will hlghhght a particular class of mlscommunlcatlon - reference problems - by descrlbmg a case study, includlng techniques for avoldlng failures of reference</Paragraph>
