This library is a Ruby interface to WordNet®. WordNet® is an online 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. It uses WordNet-SQL, which is a conversion of the lexicon flatfiles into a relational database format. You can either install the 'wordnet- defaultdb' gem, which packages up the SQLite3 version of WordNet-SQL, or install your own and point the lexicon at it by passing a Sequel URL to the constructor.
