The First Winograd Schema Challenge at IJCAI-16

Six systems were entered, exploiting a variety of technologies. None of the systems were able to advance from the first round to the second and final round. The Winograd Schema Challenge is concerned with finding the referents of pronouns, or solving the pronoun disambiguation problem. Doing this correctly appears to rely on having a solid base of commonsense knowledge and the ability to reason intelligently with that knowledge. This can be seen from considering an example of a Winograd schema. The referent of it in sentence 1 is the backpack; the referent of it in sentence 2 is the water bottle.
