wordnet 1:3.0-26.1 (amd64 binary) in ubuntu quantal

 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
 (http://www.cogsci.princeton.edu/) at Princeton University under the
 direction of Professor George A. Miller (Principal Investigator).
 .
 WordNet is considered to be the most important resource available to
 researchers in computational linguistics, text analysis, and many
 related areas. Its design is inspired by current psycholinguistic and
 computational theories of human lexical memory.
