Segmented Discourse Representation Theory Asher and Lascarides (2003) - Slides from Alex Lascarides � A dynamic semantic theory of discourse interpretation It uses rhetorical relations to model the semantics/pragmatics interface. semantic underspecification is expressed as partial descriptions of logical forms, and a glue logic which uses commonsense reasoning to construct logical forms, relating the semantically underspecified forms that are generated by the grammar to their pragmatically preferred interpretations 19/123 Pustejovsky - Brandeis Computational Event Models
