    (description
     "WordNet® is a large lexical database of English.  Nouns, verbs,
adjectives and adverbs are grouped into sets of cognitive synonyms (synsets),
each expressing a distinct concept.  Synsets are interlinked by means of
conceptual-semantic and lexical relations.  The resulting network of
meaningfully related words and concepts can be navigated with the browser.
WordNet is also freely and publicly available for download.  WordNet's
structure makes it a useful tool for computational linguistics and natural
language processing.")
