Dictionaries and Thesauri are valuable resources for Natural Language Processing but are not as widely available as one would hope, especially for languages other than English, and most can only be used for querying online. Our main goal with T2O - Thesaurus to Ontology framework - is to create a multilingual ontology: -- freely available online and for downloading; with a computer-readable format; with a good API; with a structure as rich as possible; reusing all the structured information we can get.
