Asynchronous Argumentation with Pervasive Personal Communication Tools

In this paper, we propose an argument-based communication tool for humans and agents, which supplements and alternates the current communication system such as Twitter, Line, etc. in order to allow us to make a more deliberate and logical human communication. For this purpose, we devised asynchronous argumentation based on our logic of multiple-valued argumentation. It may be as well reworded as asymptotic or incremental argumentation since agents could approach towards truth or justification every time argument is put forward by an agent. We have made real the asynchronous argumentation system, named PIRIKA (pilot of the right knowledge and argument), on the pervasive personal tool, iPad. Finally some lessons learned from the experimental uses of PIRIKA are reported.
