    <Paragraph position="1"> In this study, we give some indication of how a sophisticated and well structured adverbial lexicon can help NLP systems to handle adverbs. Our lexicon builds on the work of several linguists. Their work has helped us to organize information about adverbs from the Collins English Dictionary (CED) and other sources. The adverbial lexicon is organized using the Oracle Relational Database</Paragraph>

      <Paragraph position="0"> There have been many studies on nouns, verbs, and adjectives in NLP systems. Adverbs have received far less attention.</Paragraph>
      <Paragraph position="1"> It is very difficult for natural language processing (NLP) systems to handle adverbs because of the large number of syntactic roles that adverbs can assume in sentences. Adverbs can modify verbs, adjectives, adverbs, clauses, or the whole sentences. Adverbs obey complicated positional and selectional restrictions. Many adverbs change meanings when they change their positions in sentences. Despite this complexity, linguists have made significant progress developing a comprehensive set of adverbs classifications, and elucidating * This research was partially supported by the National Science Foundation under grant IRI8704619. Our thanks also to Collins Publishers tot permission to use the dictionary tapes.</Paragraph>
      <Paragraph position="2"> Semantic classes of adverbs and selectional restrictions are discussed in Section 2. Section 3 treats functional classes and describes some of the properties of certain functional classes of adverbs. Section 4 presents some possible applications. Finally, Section 5 concludes.</Paragraph>
