FUTURE PLANS
</SectionTitle>
    <Paragraph position="0"> In addition to pursuing our research in each of the areas described above, we will institute two new efforts next year. First of all, we will begin to extend our work in pragmatics to the recognition of discourse structure. This problem is illustrated by the following text: Air regulating valve failed.</Paragraph>
    <Paragraph position="1"> Gas turbine engine wouldn't turn over.</Paragraph>
    <Paragraph position="2"> Valve parts corroded.</Paragraph>
    <Paragraph position="3"> The temporal structure of this text is 3-1-2; first the valve parts corroded, and this caused the valve to fail, which caused the engine to not turn over. To recognize this structure, one must reason about causal relationships in the model of the device, and in addition one must recognize patterns of explanation and consequence in the text.</Paragraph>
    <Paragraph position="4"> The second new effort will be to build tools for domain knowledge acquisition. These will be based on the abstract machines in terms of which we are presently encoding our domain knowledge. Thus, the system should be able to allow the user to choose one of a set of abstract machines and then to augment it with various parts, properties and relations.</Paragraph>
