The open-source Dubsar Dictionary Project uses Ruby on Rails®, PostgreSQL, jQuery and jQuery UI to provide a simple yet dynamic interface to the Princeton University WordNet® data set, containing more than 150,000 English words and proper nouns. Users can browse or search using PostgreSQL wild cards and view word inflections, definitions and synonyms. A draggable custom tooltip displays extensive metadata for each listed word sense, including lexical classifications, syntactic adjective markers, frequency counts from a reference text, generic verb frames, sample sentences and a broad array of pointers to words related in different ways to a given sense. The site also features a hosted QUnit integration test suite. Visit Dubsar:
