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, and the WordNet project is housed in the Department of Computer Science:

George A. Miller
Christiane Fellbaum
Randee Tengi
Helen Langone
Adam Ernst
Lavanya Jose
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 judgements 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.

Our web interface has been updated to access the 3.0 database.

WordNet 3.0 for Unix systems has been released, as well as the sense mapping and Prolog packages. 3.0 for Windows will follow. You can download a local copy of WordNet.

George Miller and Christiane Fellbaum were awarded the 2006 Antonio Zampolli Prize.

Wordnets have been created in dozens of other languages. The Global WordNet Organization is coordinating and guiding new the development of new wordnets and holding biannual meetings.

A website originating in Ukraine, http://www.synset.com, has posted the data from the Princeton WordNet without acknowledgment and is furthermore claiming copyright of the Princeton data. Princeton has no connection to the Ukrainian site. Please see our license agreement for appropriate licensing information.
