Asessing the Amazon Mechanical Turk plateform

Participant : Benoît Sagot.

In collaboration with Gilles Adda and Joseph Mariani from LIMSI and with Karën Fort from INIST, we have assessed some crowdsourced microworking systems and especially Amazon Mechanical Turk, the use of which has been steadily growing in language processing in the past few years [41] , [17] . According to the mainstream opinion expressed in the articles of the domain, this type of on-line working platforms allows to develop very quickly all sorts of quality language resources, for a very low price, by people doing that as a hobby or wanting some extra cash. We have demonstrated that the situation is far from being that ideal, be it from the point of view of quality, price, workers' status or ethics and bring back to mind already existing or proposed alternatives. Our goal was threefold:

• to inform researchers, so that they can make their own choices with all the elements of the reflection in mind,

• to ask for help from funding agencies and scientific associations, and develop alternatives,

• to propose practical and organizational solutions in order to improve new language resources development, while limiting the risks of ethical and legal issues without letting go price or quality.
