VirtualECare: Group Decision Supported by idea Generation and Argumentation (original) (raw)

Argumentation and multi-agent decision making

1998

One focus of our work at Queen Mary and Westfield College is the development of multi-agent systems which deal with real world problems, an example being the diagnosis of faults in electricity distribution networks (Jennings et al. 1996). These systems are mixed-initiative in the sense that they depend upon interactions between agents--no single agent has sufficient skills or resources to carry out the tasks which the multi-agent system as a whole is faced with.

An Argumentation-Based Framework for Deliberation in Multi-agent Systems

2007

This paper focuses of the group judgments obtained from a committee of agents that use deliberation. The deliberative process is realized by an argumentation framework called AMAL. The AMAL framework is completely based on learning from examples: the argument preference relation, the argument generation policy, and the counterargument generation policy are case-based techniques. For join deliberation, learning agents share their experience by forming a committee to decide upon some joint decision. We experimentally show that the deliberation in committees of agents improves the accuracy of group judgments. We also show that a voting scheme based on assessing the confidence of arguments improves the accuracy of group judgments than majority voting.
