Experts ou (foule de) non-experts ? la question de l’expertise des annotateurs vue de la myriadisation (crowdsourcing)

Experts or (crowd of) non-experts ? the question of the annotators’ expertise viewed from crowdsourcing.Manual corpus annotation is more and more performed using crowdsourcing : produced by a crowd of persons, through the Web, for free, or for a very small remuneration. Our experiments question the commonly accepted vision : crowdsourcing a task is not having a crowd of non-experts performing it, but rather identifying experts of the (annotation) task in the crowd. Those experiments therefore contribute to the reflection on the corpus annotators’ expertise
