Interplay of Coreference and Discourse Relations: Discourse Connectives with a Referential Component
Lucie Poláková, Pavlína Jínová, Jiří Mírovský · 2012
This contribution explores the subgroup of text structuring expressions with the form preposition + demonstrative pronoun, thus it is devoted to an aspect of the interaction of coreference relations and relations signaled by discourse connectives (DCs) in a text.The demonstrative pronoun typically signals a referential link to an antecedent, whereas the whole expression can, but does not have to, carry a discourse meaning in sense of discourse connectives.We describe the properties of these phrases/expressions with regard to their antecedents, their position among the text-structuring language means and their features typical for the "connective function" of them compared to their "non-connective function".The analysis is carried out on Czech data from the approx.50,000 sentences of the Prague Dependency Treebank 2.0, directly on the syntactic trees.We explore the characteristics of these phrases/expressions discovered during two projects: the manual annotation of coreference relations (Nedoluzhko et al. 2011) and discourse connectives, their scopes and meanings (Mladová et al. 2008).
