Apertium is a free/open-source machine translation platform. The LMF (Lexical Markup Framework) version of their linguistic data is available here and has served as input for its RDF version. Additional information about Apertium can be found in its wikipedia entry.

Apertium RDF contains the RDF (Resource Description Framework) version of the Apertium bilingual dictionaries, which have been transformed into RDF and published on the Web following the Linked Data principles. The core linguistic data has been modelled using the lemon model and the translations between terms have been modelled using the lemon translation module.

The Apertium RDF version has been generated by OEG (Universidad Politécnica de Madrid) jointly with IULA (Universitat Pompeu Fabra).

Logotype based on a creation by Francis Tyers and Andrej Slapnik.
