OpenWordnet-PT: an open Brazilian Wordnet

branch: master


About the RDF conversion

  • Based on and with some modifications. More files from the Princeton distribution were considered and not only the database files. More properties and classes are included.

  • Lisp code used to create the RDF files will be made available soon.

  • The wordnet-br.rdf is not a complete wordnet. All relations are in the wordnet-en.rdf (the original Princeton WordNet 3.0).

How the project started?

The initial file 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 UWN and MENTA provided candidate terms in Portuguese, candidate glosses in Portuguese (from Wikipedia), and candidate terms in Spanish.

  • 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.
