TYTUŁ:     Disambiguating Hypernym Relations for Roget's Thesaurus


Roget's Thesaurus is a lexical resource which groups terms by semantic
relatedness.  It is Roget's shortcoming that the relations are
ambiguous, in that it does not _name_ them; it only shows that there
_is_ a relation between terms.  Our work focuses on disambiguating
hypernym relations within Roget's Thesaurus.  Several techniques of
identifying hypernym relations are compared and contrasted in this
paper, and a total of over 50,000 hypernym relations have been
disambiguated within Roget's. Human judges have evaluated the quality
of our disambiguation techniques, and we have demonstrated on several
applications the usefulness of the disambiguated relations.
