COMPUTER-MEDIATED ARGUMENTATION SUPPORT SYSTEM (CASS):Structured Conversational Analysis Approach

초록

This paper aims at outlining the Computer-mediated Argumentation Support System (CASS) with the approach of structured conversational analysis. Argumentation can be defined as a conversational activity exchanging views to attack and defend the different opinions expressed by the participants with the goal of convincing the opponent. The goal of CASS is not to replace argumentative activity of a human-being with computer but to help the users of the system by giving analytic power to enhance the effectiveness of their own rational argumentation thus promote the effective resolution of the conflict. The problems we must deal with in developing CASS are 1) What is the structure of argumentative discussions? 2) How does the argumentative discussion develop (rules and procedure)? 3) What are the rules required to support these argumentative conversations? Two main tasks in developing conversational argumentation model will be defining its structure and rules governing the unfolding procedure of the conversation. This paper adopts Toulmin's basic argumentation model to define the structure of each argument and integrated various notions of Dialogue logic such as Hamblin, Mackenzie, Lorenzen and Barth to define the rules of argumentation. The structure of conversational events and fifteen rules in five categories are developed in this paper.
