Abstract
A debate game provides an abstract model of debates between two players
based on the formal argumentation framework.
This paper presents a method of realizing debate games in logic programming.
Two players have their knowledge bases represented by extended logic programs
and build claims using arguments associated with those programs. A player revises its knowledge base
with arguments posed by the opponent player, and tries to refute claims by the opponent.
During a debate game, a player may claim false or incorrect arguments as a tactic to win the game.
The result of this paper provides a new formulation of debate games in
a non-abstract argumentation framework associated with logic programming.
Moreover, it provides a novel application of logic programming to modelling social debates
which involve argumentative reasoning, belief revision and dishonest reasoning.
