While SPARQL is a powerful way of accessing linked data, using natural language is more intuitive for most users. A few question answering systems already exist for English, but none focus specifically on French. Our system allows a user to query the DBpedia knowledge by asking questions in French separated in specific types, which are automatically translated into SPARQL queries. To our knowledge, this is the first French-based question answering system in the QALD competition.
