Presupposition Accommodation in a Constructive Update Semantics
Joris Hulstijn, Gert Durieux, Walter Daelemans, Steven Gillis · University of Twente Research Information · 1996
Presupposition concerns information that is assumed to be part of the discourse-context by the speaker, as apparent from the syntactic form of the utterance. The hearer, being cooperative, will normally fill in missing presupposed information, provided it is compatible with his/her version of the discourse-context. Several different approaches to this process of presupposition accommodation can be characterized using update semantics with an additional stack-structure. Semantic tableaux can be used to represent the information states of update semantics. Branches of tableaux are constructed during interpretation. Therefore the approach may be labeled a constructive update semantics.
