Starting from an agent vs agent case, we address the optimization of the agent strategy by formulating the problem as a Stochastic Game and show that this formalism generally allows the inclusion of additional strategical moves that are not based on the content of the argument. In a second step we propose our approach for the Natural Language Understanding of arguments by combining recent results of argumentation mining with a keyword-based mapping.application/pdfengCopyright © 2017 the authorsinfo:eu-repo/semantics/conferenceObjectArgumentationNatural Language UnderstandingStochastic gamesinfo:eu-repo/semantics/openAccess
