Logic-Based Rhetorical Structuring for Natural Language Generation in Human-Computer Dialogue

Abstract. Rhetorical structuring is field approached mostly by research in natural language (pragmatic) interpretation. However, in natural language generation (NLG) the rhetorical structure plays an important part, in monologues and dialogues as well. Hence, several approaches in this direction exist. In most of these, the rhetorical structure is calculated and built in the framework of Rhetorical Structure Theory (RST), or Centering Theory [7], [5]. In language interpretation, a more recent formal account of rhetorical structuring has emerged, namely Segmented Discourse Representation Theory (SDRT), which alleviates some of the issues and weaknesses inherent in previous theories [1]. Research has been initiated in rhetorical structuring for NLG using SDRT, mostly concerning monologues [3]. Most of the approaches in using and / or approximating SDRT in computer implementations lean on dynamic semantics, derived from Discourse Representation Theory (DRT) in order to compute rhetorical...
