Evaluation of a Narrative Discourse Generation System Based on the Concept of "Norm and Deviation"

This paper deals with the verification of a narrative discourse system. The system automatically produces a variety of discourse structures from an inputted story structure through an iterative mutual action between a narrator and narratee mechanisms. We analyze a series of generated discourse structures according to their structural feature values by focusing on the diachronic alternation of norms, the narratee’s expectation in receiving discourses. Based on the results, we discuss achievement and issues to be addressed.
