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, 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.
This material is based upon work supported by the National Science Foundation under Grant No. 0855157.

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. This is a corpus of manually annotated WordNet synset defintions ("glosses"). We invite you to use this freely available corpus. Please refer to the "Princeton Annotated Gloss Corpus" in any publications.
