While parsing a sentence, the DtLS for that sentence is processed by A-conversion and merging, using syntax rules of the following form 5 (as in [Alshawl, 1992]): np:[drs=Drs,agr=Agr .... ] ---> [det:[drs=A2"Drs .... ], noun:[drs=Al,agr=Agr .... ], optrel:[drs=Al'A2,...]]. The output of a sentence parse is a constructed DRS for that sentence, but with referring expressions (if any) still unresolved. This sentence-DRS then is merged with the ingoing DRS, representing the computed discourse so far. During this merge, the following computing actions take place: • Computing of arguments for PDRSs; • Resolving of Pronouns and'VP Ellipsis; • Accommodation of Proper Names, Definite Descriptions, and Possessive Constructions. An aid to these computations is a historylist computed during the ...
