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.
