About WordNet
WordNet® is a large lexical database of English, developed under the direction of George A. Miller. 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.
Over the years, many people have contributed to the development of WordNet. Currently, the WordNet team includes the following members of the Cognitive Science Laboratory:
- George A. Miller
- Christiane Fellbaum
- Randee Tengi
- Pamela Wakefield
- Helen Langone
WordNet has been supported by grants from the NSF, ARDA, DARPA, DTO, and REFLEX.

New tools for researchers
The "evocation" project collects human judgements on how much one synset brings to mind another. 100,000 semantic similarity jugements from at least three human raters. A ranking of synsets derived from word frequencies in the British National Corpus; synsets have been selected by salience. Download these packages from http://wordnet.cs.princeton.edu/downloads.html.
The Morphosemantic Links package is now available from our download page.
The semantically annotated "gloss corpus" is available for download.
