| Abstract | This paper contributes to the question of which degree of complexity is calledfor in representations of discourse structure. We review recent claims thattree structures do not suffice as a model for discourse structure, with a focuson the work done on the Discourse Graphbank (DGB) of Wolf and Gibson (2005,2006). We will show that much of the additional complexity in the DGB is notinherent in the data, but due to specific design choices that underlie W&G’sannotation. Three kinds of configuration are identified whose DGB analysisviolates tree-structure constraints, but for which an analysis in terms of treestructures is possible, viz., crossed dependencies that are eventually based onlexical or referential overlap, multiple-parent structures that could behandled in terms of Marcu’s (1996) Nuclearity Principle, and potential liststructures, in which whole lists of segments are related to a preceding segmentin the same way. We also discuss the recent results which Lee et al. (2008)adduce as evidence for a complexity of discourse structure that cannot behandled in terms of tree structures. |
