6. SUMMARY
</SectionTitle>
    <Paragraph position="0"> We presented Virtual Annotation, a technique to extend the capabilities of PA to a class of definition questions in which the answer type is not easily identifiable. Moreover, VA can find text snippets that do not contain the regular textual clues for presence of definitions. We have shown that VA can considerably improve the performance of answering What is questions, and we indicate how other kinds of questions can be tackled by similar techniques.</Paragraph>
