4. Strong generative capacity of RST, SDRT and discourse dependency DAGSs
The aim of this paper0 is to compare the discourse structures proposed in rst, sdrt and dependency dags which extend the semantic level of mtt for discourses. The key question is the following: do these formalisms allow the representation of all the discourse structures which correspond to felicitous discourses and exclude those which correspond to infelicitous discourses? Hence the term of “strong generative capacity” taken from formal grammars.
