Anaphora as an Indicator of Elaboration: A Corpus StudyThis article describes an investigation of the relationship between anaphora and relational discourse structure, notably the Elaboration relation known from theories like RST.A corpus was annotated on the levels of anaphoric structure and rhetorical structure.The statistical analysis of interrelations between the two annotation layers revealed correlations between specific subtypes of anaphora and Elaboration, indicating that anaphora can function as a cue for Elaboration. The work presented in this article is a joint effort of the projects A (Sekimo) and C (SemDok ) of the Research Group Text-technological modelling of information funded by the German Research Foundation DFG.JLCL 2008 -Volume 23 (2) -49-72 We would like to thank the two anonymous reviewers who provided valuable comments on a previous version of this article. The term sentential nominal refers to constructions that are semantically related to sentential structures, e.g.due to a derived nominal as in Example () (cf.Asher, ).50 JLCL Bärenfänger, Goecke, Hilbert, Lüngen, Stührenberg not decide on one terminal type were they allowed to annotate one of the intermediate types.Elaboration Elaboration-definition Elaboration-derivation Elaboration-example Elaboration-identity Elaboration-continuation Elaboration-drift Elaboration-continuation-other Elaboration-specification Elaboration-assign Elaboration-assign-abbreviation Elaboration-assign-other Elaboration-specification-other Elaboration-integration Elaboration-restatement *Elaboration-class-subclass *Elaboration-class-instance *Elaboration-set-member *Elaboration-whole-part *Elaboration-process-step *Elaboration-theme-theme *Elaboration-rheme-theme
