Prof. Dr. Bonnie Webber Lexicalised Discourse Grammar: Discourse Semantics through Structure and Anaphora The overall goal of this work is to explore the hypothesis that, just as with sentence-level semantics, the semantics of discourse can be seen as a projection from the lexicon and syntax, coupled with anaphoric processes and inference. We do this by setting up a lexicalised discourse grammar, and then showing with respect to this grammar that relations between clausal interpretations can arise both compositionally, from structure, and from anaphoric connections mediated by the lexicon. Additional conclusions, from defeasible inference, augment both. The approach aims for simplicity and clarity in both Natural Language generation and understanding. (This work has been carried out with Aravind Joshi (UPenn), Alistair Knott (U Otago) and Matthew Stone (Rutgers U).) |
