Solving Hard Coreference Problems
Table 9: Distribution of instances in Winograd dataset of each category. Cat1/Cat2 is the subset of instances that require Type 1/Type 2 schema knowledge, respectively. All other instances are put into Cat3. Cat1 and Cat2 instances can be covered by our proposed Predicate Schemas.
['Category', 'Cat1', 'Cat2', 'Cat3']
Detailed Analysis To study the coverage of our Predicate Schemas knowledge, we label the instances in Winograd (which also applies to WinoCoref) with the type of Predicate Schemas knowledge required. The distribution of the instances is shown in Table 9. Our proposed Predicate Schemas cover 73% of the instances.
