Abstract : Since September 2007, a large scale lexical network for French is under construction with methods based on popular consensus by means of games (under the JeuxDeMots project). To assess the quality of such a resource built by non-expert users (players of the games), we decided to adopt an approach similar to its construction, that is to say an evaluation by laymen on open class vocabulary. This evaluation is done using a Tip of the Tongue tool.
