A Dependency-based Approach to Anaphora Annotation
Eckhard Bick · University of Southern Denmark Research Portal (University of Southern Denmark) · 2010
The paper describes a novel approach to the resolution of pronominal anaphora, where a hierarchy of linguist-written Constraint Grammar rules are used to add relational tags to anaphoric tokens in running text. Pro-drop subjects are covered as well as multi-sentence anaphoric chains. The system exploits function-marked dependency trees provided by a CG parser, and performs semantic tagging of pronouns as an intermediate step, based on verbonominal selection restrictions harvested from a collocation corpus. News text evaluation results are provided and compared across different anaphora types.
