WinoFlexi: A Crowdsourcing Platform for the Development of Winograd Schemas

The Winograd Schema Challenge, the task of resolving pronouns in certain carefully-structured sentences, has received considerable interest in the past few years as an alternative to the Turing Test. Systems developed to tackle this challenge have typically been evaluated on a small set of hand-crafted collections of sentences, since the development of new sentences by individuals is itself a rather challenging task, requiring care and creativity. In this paper we approach the problem of developing Winograd schemas via the introduction of WinoFlexi, a flexible online crowdsourcing system. Our empirical evaluation of the system’s performance suggests that WinoFlexi allows crowdworkers to develop Winograd schemas of quality similar to that of most typical existing collections.
