Labelled representations underspecification and disambiguation. (English) Zbl 1004.03024

This paper is concerned with the problem of utterance meaning disambiguation from the perspective of the well-known Discourse Representation Theory (DRT) of H. Kamp and U. Reyle (1984, 1993). Trying to disambiguate the discourse subexpressions, the authors propose to improve a labelling structure over the discourse representation structures (DRSs), thus attempting to combine two extensions of DRT, the Underspecified DRT (UDRT) of U. Reyle (1993) and Segmented DRT (SDRT) of N. Asher (1993) et al. Because of the striking logical contrast in disambiguation between SDRT and UDRT, their “marriage” could have really important consequences for discourse interpretation. By allowing underspecifications at all levels, the requirements on contextual update seem to reduce disambiguation only when the gains are worth the computational effort.
