Database Packages

The most recent Windows version of WordNet is 2.1, released in March 2005. Version 3.0 for Unix/Linux/Solaris/etc. was released in December, 2006. The version 3.1 database files only (no code) can be downloaded and substituted for the 3.0 files in applications and with WordNet's Unix/Linux application. Version 3.1 is also available when using the online interface.

Download the latest WordNet packages, including the Prolog version and sense mapping files.

Standoff Files

Several "standoff" files provide further semantic information to supplement the WordNet 3.0 release.

The standoff files include:

  • Semantically annoted gloss corpus
  • Evocation database
  • Morphosemantic Links (Semantic relations between morphologically related nouns and verbs)
  • Teleological Links (an encoding of typical activity for which artifact was intended)
  • "Core" WordNet (5000 more frequently used word senses)
  • Logical Forms (logical forms for glosses)

Contact Christiane Fellbaum if you are interested in obtaining these files.
