Dataset Card for The Winograd Schema Challenge

Dataset Summary

A Winograd schema is a pair of sentences that differ in only one or two words and that contain an ambiguity that is resolved in opposite ways in the two sentences and requires the use of world knowledge and reasoning for its resolution. The schema takes its name from a well-known example by Terry Winograd:

The city councilmen refused the demonstrators a permit because they [feared/advocated] violence.

If the word is feared'', then they'' presumably refers to the city council; if it is advocated'' then they'' presumably refers to the demonstrators.

Supported Tasks and Leaderboards

From the official webpage:

A contest, entitled the Winograd Schema Challenge was run once, in 2016. At that time, there was a cash prize offered for achieving human-level performance in the contest. Since then, the sponsor has withdrawn; therefore NO CASH PRIZES CAN BE OFFERED OR WILL BE AWARDED FOR ANY KIND OF PERFORMANCE OR ACHIEVEMENT ON THIS CHALLENGE.

Dataset Structure

Data Instances

Each instance contains a text passage with a designated pronoun and two possible answers indicating which entity in the passage the pronoun represents. An example instance looks like the following:

{
  'label': 0,
  'options': ['The city councilmen', 'The demonstrators'],
  'pronoun': 'they',
  'pronoun_loc': 63,
  'quote': 'they feared violence',
  'quote_loc': 63,
  'source': '(Winograd 1972)',
  'text': 'The city councilmen refused the demonstrators a permit because they feared violence.'
}

Data Fields

• text (str): The text sequence
• options (list[str]): The two entity options that the pronoun may be referring to
• label (int): The index of the correct option in the options field
• pronoun (str): The pronoun in the sequence to be resolved
• pronoun_loc (int): The starting position of the pronoun in the sequence
• quote (str): The substr with the key action or context surrounding the pronoun
• quote_loc (int): The starting position of the quote in the sequence
• source (str): A description of the source who contributed the example

Data Splits

Only a test split is included.

Dataset Creation

Curation Rationale

The Winograd Schema Challenge was proposed as an automated evaluation of an AI system's commonsense linguistic understanding. From the webpage:

The strengths of the challenge are that it is clear-cut, in that the answer to each schema is a binary choice; vivid, in that it is obvious to non-experts that a program that fails to get the right answers clearly has serious gaps in its understanding; and difficult, in that it is far beyond the current state of the art.

Source Data

Initial Data Collection and Normalization

This data was manually written by experts such that the schemas are:

• easily disambiguated by the human reader (ideally, so easily that the reader does not even notice that there is an ambiguity);

• not solvable by simple techniques such as selectional restrictions;

• Google-proof; that is, there is no obvious statistical test over text corpora that will reliably disambiguate these correctly.

Who are the source language producers?

This dataset has grown over time, and so was produced by a variety of lingustic and AI researchers. See the source field for the source of each instance.

Annotations

Annotation process

Annotations are produced by the experts who construct the examples.
