WordNet Identifiers

Words are identified by means of the following URI scheme:

http://wordnet-rdf.princeton.edu/wn31/word-[nvarsp]

Where [nvarsp] is the part-of-speech. Similarly synsets are identified as follows

http://wordnet-rdf.princeton.edu/id/[8 digit code]-[nvarsp]

Where the 8-digit code is the identifier of the synset.

Each file may be downloaded in a given format by adding a file extension to the URL. For example, adding .json to the URL gives the JSON version of the word or synset, e.g.,

http://wordnet-rdf.princeton.edu/id/00001740-n.json

The following formats are supported:

It is also possible to use synset identifiers from WordNet 2.0 and WordNet 3.0. The URIs use the 8-digit synset code and the part-of-speech letter code, for example as follows:

http://wordnet-rdf.princeton.edu/pwn20/00001740-a
http://wordnet-rdf.princeton.edu/pwn30/00001740-a
