Creating Large-Scale Argumentation Structures for Dialogue Systems

Abstract

We are planning to develop argumentative dialogue systems that can discuss various topics with people by using large-scale argumentation structures. In this paper, we describe the creation process of these argumentation structures. We created ten structures each having more than 2000 nodes of five topics in English and five topics in Japanese. We analyzed the created structures for their characteristics and investigated the differences between the two languages. We conducted an evaluation experiment to ascertain that the structures can be applied to dialogue systems. We conducted another experiment to use the created argumentation structures as training data for augmenting the current argumentation structures.
