5. CONCLUSION AND FUTURE WORK
</SectionTitle>
    <Paragraph position="0"> The demonstration system described above illustrates the effect of TDT technology. It is also interesting in its own right, allowing a user to track news topics of interest and to see how changes occur over time. There is no reason that the same system could not be used for non-TDT environments: any setting that clusters documents might be appropriate for this system.</Paragraph>
    <Paragraph position="1"> We are working to extend the demonstration system to include some additional features.</Paragraph>
    <Paragraph position="2"> + Considering the large number of topics (almost 3,000 in Figure 3), it is unlikely that all &amp;quot;interesting&amp;quot; topics will be PSndable. The query box at the top of the display will be used to allow the user to PSnd topics that match a request. The ranked list will display the top 50 topics that match the query.</Paragraph>
    <Paragraph position="3"> + Related to querying, we hope to include an &amp;quot;alert&amp;quot; feature that will $?ag newly-created topics that match a query. For example, an analyst interested in the Middle East might develop a query that would identify topics in that region. When such a topic appeared, it would be $?agged for the user (probably with a &amp;quot;hot topic&amp;quot; color).</Paragraph>
    <Paragraph position="4"> + We hope to allow user &amp;quot;correction&amp;quot; of the topic breakdown provided by the TDT system. The state-of-the-art in TDT still makes mistakes, sometimes pulling two similar topics together, and sometimes breaking a single topic into multiple clusters. We intend that a user who sees such a mistake be able to indicate it to the system. That information will, in turn, to be relayed back to the TDT system to affect future processing.</Paragraph>
    <Paragraph position="5"> + We will be implementing an &amp;quot;explode this topic&amp;quot; feature that will show the stories within a topic analogously to the way the current system shows the topics within the news. If the topic is small enough, for example, the spheres would represent stories within the topic. If the topic is larger, the spheres might represnt sub-clusters within the topic.</Paragraph>
