The number of thesauri is increasing. Evolution is quite the same as last year for creation of new thesauri (figure above) but 25% increasing in data quantity (figure beneath). New thesauri started with a better quality and older thesauri had gain also. There is several way to explain this evolution. The first one may be a systematic link to associate thesaurus added in Wikipedia related pages. It may have raised the quantity of readers coming from Wikipedia. Another explanation may be the creation of thesauri during public events like the one on handisport during a collaborative event on Paralympic Games. Last dynamic is the Lexisession, evoked in Actualités and quite popular. New creation drive new people to read the other thesauri and to improve them. Stats on new contributors are not available yet, so we'll be talking back about it next year!
