12 CONCLUSIONS
</SectionTitle>
    <Paragraph position="0"> This paper has described a new method for responding to misconceptions that relies on an analysis of a highlighted user model to generate a response that is most likely to benefit the user. A number of strategies were abstracted from a study of transcripts. Each strategy was associated with a distinguished structure in the user model which could explain its use in a given situation. A system can use this pairing to decide how to respond by looking in the highlighted user model for evidence of one of the distinguished structures. The corresponding strategy can be used to respond.</Paragraph>
    <Paragraph position="1"> In addition, the paper has described a new notion of object perspective that is able to model one aspect of the dynamic highlighting of the user model due to previous discourse. It was shown how perspective could account for certain contextual affects on responses to misconceptions.</Paragraph>

NOTES
1. While in general it may be necessary for the user model to contain
</SectionTitle>
    <Paragraph position="0"> more information about the user (e.g., goals and plans), these are not required for the restricted task set out in this paper.</Paragraph>
    <Paragraph position="1"> 2. The dialogs contained in this paper were not taken directly from the transcripts. They are used to illustrate the kinds of responses found.</Paragraph>
    <Paragraph position="2"> 3. Saying that exactly one perspective is active is actually a simplification. It may be the case that a number of perspectives can be active. In this case the resulting &amp;quot;active perspective&amp;quot; will be some function of the individual active perspectives. The exact nature of this function is an open research question.</Paragraph>
    <Paragraph position="3"> 4. Note that the ROMPER system does not choose the active perspective--it is given as input to the system. This example is simply used to illustrate perspective's influence on misconception responses.</Paragraph>
