Hi Benoit, sorry for the late reply. We provide the data for this in two ways fromt the Wiktionary2RDF project at DBpedia (http://dbpedia.org/Wiktionary) SPARQL endpoint: http://wiktionary.dbpedia.org/sparql with query: select * from <http://fr.wiktionary.dbpedia.org> where { ?s <http://wiktionary.dbpedia.org/terms/hasMeaning> ?o } or download from: http://downloads.dbpedia.org/wiktionary/dumps/ wget http://downloads.dbpedia.org/wiktionary/dumps/fr_wiktionary_current.nt.bz2 bzcat fr_wiktionary_current.nt.bz2 grep fr_wiktionary_current.nt | grep "hasMeaning" I hope that helps. You would save parsing the dump, and could use OpenNLP directly. All the best, Sebastian Am 21.03.2013 16:06, schrieb Federico Leva (Nemo): -- Dipl. Inf.
