electronic lexical database of English language (index)

 WordNet(C) is an on-line lexical reference system whose design is
 inspired by current psycholinguistic theories of human lexical
 memory. English nouns, verbs, adjectives and adverbs are organized
 into synonym sets, each representing one underlying lexical
 concept. Different relations link the synonym sets.
 .
 WordNet was developed by the Cognitive Science Laboratory at Princeton
 University under the direction of Professor George A. Miller (Principal
 Investigator).
 .
 This package contains a large database index.sense which is not
 necessary for normal operation of the wordnet package but is useful
 when using the WordNet::QueryData module which is available at
 http://search.cpan.org/dist/WordNet-QueryData/ .
