Comparing bridging annotations across coreference resources is difficult,
largely due to a lack of standardization across definitions and annotation
schemas and narrow coverage of disparate text domains across resources. To
alleviate domain coverage issues and consolidate schemas, we compare guidelines
and use interpretable predictive models to examine the bridging instances
annotated in the GUM, GENTLE and ARRAU corpora. Examining these cases, we find
that there is a large difference in types of phenomena annotated as bridging.
Beyond theoretical results, we release a harmonized, subcategorized version of
the test sets of GUM, GENTLE and the ARRAU Wall Street Journal data to promote
meaningful and reliable evaluation of bridging resolution across domains.
