Open English WordNet is a lexical network of the English language grouping words into synsets and linking them according to relationships such as hypernymy, antonymy and meronymy. It is intended to be used in natural language processing applications and provides deep lexical information about the English language as a graph.
Open English WordNet is a fork of the Princeton Wordnet developed under an open source methodology. The quality and veracity of the resource may differ from the Princeton WordNet and we welcome contributions. Contributions to this wordnet may eventually be incorporated into future releases of Princeton WordNet. Correspondance to previous versions and wordnets in other language is provided through the Collaborative Interlingual Index (CILI). The Open English WordNet is available as individual files in GWN-LMF format.
Open English WordNet is released through the Open English WordNet website. The versions released are
