Discourse Grammar

Laurence Danlos (Alpage Inria project), Aleksandre Maskharashvili, and Sylvain Pogodalla have presented a method to interface a sentential grammar and a discourse grammar. It offers both a smooth integration of the two grammars without using an intermediate processing step, and the possibility to build discourse structures that are direct acyclic graphs (DAG) and not only trees. The analysis is based on a Tree-Adjoining Grammar (TAG) approach to discourse: Discourse Synchronous TAG (D-STAG)  [50] , [51] , and uses an encoding of TAG into ACG. This allows for expressing a higher-order semantic interpretation that enables building DAG discourse structures, and for smoothly integrating the sentential and the discourse grammar thanks to the modular capability of ACG. All the examples may be run and tested with the the ACGtk (submitted).
