Konferensbidrag (refereegranskat)abstract
- We present a sketch of a formulation of an analysis of clarification ellipsis using dependent record types as they have been developed in Martin-Löf type theory. Record types provide a semantic formalism which at the same time as containing the normal paraphernalia of semantics (functions, binding, quantification) also have strong similarities to typed feature structures as used in HPSG. We argue that this gives us the kind of tools we need to account for the interpretation of clarification ellipses which to a large extent need to be constructed from semantic, syntactic and phonological information about the utterance being clarified. Clarification ellipses thus motivate a radical kind of context dependence over and above compositional semantics. Their meanings need to be constructed by the manipulation of structured representations of previous utterances which include more than just semantic information.

Tidskriftsartikel (refereegranskat)abstract
- The paper investigates an elliptical construction, Clarification Ellipsis, that occurs in dialogue. We suggest that this provides data that demonstrates that updates resulting from utterances cannot be defined in purely semantic terms, contrary to the prevailing assumptions of existing approaches to dynamic semantics. We offer a computationally oriented analysis of the resolution of ellipsis in certain cases of dialogue clarification. We show that this goes beyond standard techniques used in anaphora and ellipsis resolution and requires operations on highly structured, linguistically heterogeneous representations. We characterize these operations and the representations on which they operate. We offer an analysis couched in a version of Head-Driven Phrase Structure Grammar combined with a theory of information states (IS) in dialogue. We sketch an algorithm for the process of utterance integration in ISs which leads to grounding or clarification. The account proposed here has direct applications to the theory of attitude reports, an issue which is explored briefly in the concluding remarks of the paper.
