If someone has solved this particular type of problem (Winograd Schema), I'd be keen to know.

it refers to a breakable object made of either glass or iron. the ai then scans usages of the word shatter to see if it more commonly is used to describe glass or iron.
i searched google. "shatter iron" returns 500,000 results. "shatter glass" returns 2 million. 4/5 chance it refers to the item made of glass. in quotes the phrases return 4,640/186,000.
Wikipedia has another example (the original Winograd Schema) that doesn't allow you to "solve" the problem by asking Google:
The city councilmen refused the demonstrators a permit because they feared violence.
The city councilmen refused the demonstrators a permit because they advocated violence.
To what does "they" refer in each sentence?
