Starting from 1.0.0, we are planning to make periodical releases. The criteria for new releases will be:

  • MAJOR :: systematic changes in a large set of synsets. changes in the format of the files. changes in the schema of the XML/RDF used to distributed the data.

  • MINOR :: occasional changes to a limited number of synsets given a periodical revision, addition or removal of a few synsets. mainly related to changes in words of synsets.

  • PATCH :: correction of typos or coding errors etc.

History of the Project

The initial version was generated by combining the following data:

  • Princeton WordNet 3.0 was used to obtain English glosses and English terms for synset IDs.

  • The unreleased 2010-12 version of [UWN] ( and MENTA provided candidate terms in Portuguese, candidate glosses in Portuguese (from Wikipedia).

  • The EuroWordNet base concept list (5000_bc.xml) provides the base concept numbers. The original file was mapped from WordNet 2.0 to 3.0 using the mappings from WN-Map. When multiple mappings for a WordNet 2.0 synset existed, all possible WordNet 3.0 synsets were kept. Hence, there may be multiple entries with the same base concept number.
