Winventor: A Machine-driven Approach for the Development of Winograd Schemas

Nicos Isaak; Loizos Michael

The Winograd Schema Challenge—the task of resolving pronouns in certain carefully-constructed sentences —has recently been proposed as a basis for a novel form of CAPTCHAs. Such uses of the task necessitate the availability of a large, and presumably continuously-replenished, collection of available Winograd Schemas, which goes beyond what human experts can reasonably develop by themselves. Towards tackling this issue, we introduce Winventor, the first, to our knowledge, system that attempts to fully automate the development of Winograd Schemas, or at least to considerably help humans in this development task. Beyond describing the system, the paper presents a series of three studies that demonstrate, respectively, Winventor’s ability to replicate existingWinograd Schemas from the literature, automatically develop reasonableWinograd Schemas from scratch, and aid humans in developing Winograd Schemas by post-processing the system’s suggestions.
