Mixed-initiative argumentation: Group decision support in medicine

Abstract

This paper identifies ways in which traditional approaches to argumentation can be modified to meet the needs of practical group decision support. Three specific modifications are proposed. Firstly, a framework for accrual-based argumentation is presented. Second, a framework for outcome-driven decision rationale management is proposed that permits a novel conception of mixed-initiative argumentation. The framework is evaluated in the context of group decision support in medicine. © 2010 Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.
