SUMMARY
</SectionTitle>
    <Paragraph position="0"> W7 contains a wealth of implicit information. We have presented methods for making some of this information explicit by focussing on specific formulae found in noun, verb, and adjective definitions. Most of these formulae appear at the start of definitions, but we have also demonstrated that important information can be extracted from syntactic and graphemic elements, such as parentheticals. The information we have extracted involves lexical relationships such as taxonomy and set membership, selectional restrictions, and special subcategories of nouns, verbs, and adjectives. This information is used by an automatic lexicon builder to create lexical entries automatically from W7 definitions.</Paragraph>
