7. SUMMARY
</SectionTitle>
    <Paragraph position="0"> This paper has addressed the problem of disparity between the context model inferred by a natural language system and the plan under construction by an information-seeker. We have presented a four phase approach and have argued that handling disparate plans requires an enriched context model. This model must permit the addition of components suggested by the information-seeker but not fully supported by the system's domain knowledge and must differentiate among its components according to the kind of support accorded each component as a correct part of the information-seeker's overall plan. We have further argued that support for a component should affect the system's hypothesis about the source of error once plan disparity is suggested.</Paragraph>
