Aspecto-Temporal Representation for Discourse Analysis: An Example of Formal Computation

This paper studies aspecto-temporal representation and the temporal relations of discourse. We give a formal definition of different aspectual operators from the formal notions of states, events and process which are necessary for adequate analysis of aspects and tenses in natural languages. The aim of this work is not to present a deep comparison of the two models (SDRT and CAG) but to focus on the presentation of a cognitive and computational architecture of the CAG. Our study is specifically based on the computational and cognitive architecture with 7 levels of representations in the CAG in using Combinatory Logic. This architecture allows relating by formal calculus abstract semantic representations and linguistic observables. We focus on temporal relations of discourse and the insertion of a predicative relation in different temporal frameworks.
