  abstract = "<p>In text, lexical cohesion is the result of chains of
             related words that contribute to the
             continuity of lexical meaning.  These lexical chains are
             a direct result of units of text being about the same thing.
             Finding text structure involves finding units of text that are
             about the same thing.  Hence, computing the chains is useful since
             they will have a correspondence to the structure of the text.
             Determining the structure of text is an essential step
             in determining the deep meaning of the text.  
             In this thesis, a thesaurus is
             used as the major knowledge base for computing lexical chains.
             Correspondences between lexical chains and structural elements
             are shown to exist.  Since the lexical chains are computable,
             and exist in non-domain-specific text, they provide a valuable
             indicator of text structure.</p>"
