Coreference Resolution Quiz

Answers and explanations appear as you take the quiz.

1. When grouping Maria and she in Maria said she was tired, what identity relationship does coreference resolution investigate?
   • Whether the two mentions refer to the same entity
   • Whether the passage must be translated first
   • Whether both words have the same spelling
   • Whether the sentence has exactly two punctuation marks
2. Linking a pronoun to an earlier expression for the same referent is a familiar example of which relation?
   • Document-level sentiment classification
   • Image segmentation
   • Pronominal anaphora
   • Alphabetical token sorting
3. Why is the sentence "The trophy did not fit in the suitcase because it was too big" a classic hard case (a Winograd schema)?
   • It contains a spelling error
   • It has no pronouns at all
   • It is written in passive voice
   • Deciding what "it" refers to requires real-world knowledge, not just grammar
4. Why does coreference resolution matter for tasks like summarization and question answering?
   • It makes the text font larger
   • Mistaking which entity a word refers to leads to wrong or confusing outputs
   • It speeds up the computer's hard drive
   • It is only useful for poetry
5. How do influential span-ranking coreference models construct mention links?
   • By requiring all names to be alphabetically adjacent
   • By deleting every pronoun before analyzing identity
   • By scoring candidate mentions and potential earlier antecedents
   • By assigning every span the same database record
6. Which information can provide cues for a coreference model without guaranteeing a correct link?
   • Mention distance, grammatical agreement, and contextual information
   • Text color alone
   • The speed at which the user typed
   • A requirement that occupation stereotypes determine gender
7. What extra step distinguishes entity linking from grouping coreferent mentions inside a document?
   • Counting how many pronouns appear without resolving them
   • Associating a mention with a disambiguated external knowledge-base entry
   • Changing every mention to uppercase
   • Requiring every mention to be a different entity
8. What does WinoBias examine through occupation-based, Winograd-style pronoun examples?
   • The screen resolution used to display occupations
   • A guarantee that every occupation has one gender
   • The file size of every trained model
   • Differences between pro-stereotypical and anti-stereotypical coreference performance
