Planning Argumentative Texts

Abstract

This paper presents \proverb\, a text planner for argumentative texts. \proverbś main feature is that it combines global hierarchical planning and unplanned organization of text with respect to local derivation relations in a complementary way. The former splits the task of presenting a particular proof into subtasks of presenting subproofs. The latter simulates how the next intermediate conclusion to be presented is chosen under the guidance of the local focus.
