A Mystery of Pronoun Resolution

Q: Who does “he” refer to?Pronoun resolution techniques fail!(Hobbs Algorithm, Centering Theory)

• A lost to B at tug-of-war although he was weak.• A didn’t beat B at tug-of-war because he was strong.etc…

Resolution encoded in meaning, not syntax

• A beat B at tug-of-war because he was strong.• A beat B at tug-of-war because he was weak.

Why Winograd Schema?

A Tale of Two Interpretations11. Brandon beat Ryan at tug-of-war,

although he is weak.

He = Brandon?He = Ryan?

Although [he=Brandon] is weak, Ryan is even weaker.

A Tale of Two Interpretations11. Brandon beat Ryan at tug-of-war,

although he is weak.

Although [he=Ryan] isweak, Brandon is even weaker.

Although [he=Brandon] is weak, the God of Weaklings helped him win.
