How Dependency Trees and Tectogrammatics Help Annotating Coreference and Bridging Relations in Prague Dependency Treebank

摘要

In this paper, we explore the benefits of dependency trees and tectogrammatical structure used in the Prague Dependency Treebank for annotating language phenomena that cross the sentence boundary, namely coreference and bridging relations. We present the benefits of dependency trees such as the detailed processing of ellipses, syntactic decisions for coordination and apposition structures that make possible coding coreference relations in cases that are not so easy when annotating on the raw texts. We introduce the coreference decision for non-referring constructions and present some tectogrammatical features that are useful for annotation of coreference.
