Discussion Map with an Assistant Function for Decision-Making: A Tool or Supporting Consensus-Building

摘要

In this paper, we propose a tool for supporting consensus-building in conversations with multiple participants. We call it "Discussion Map with Assistant (DMA)". It consists of nodes and links. We classify the nodes into two types; alternatives and criteria. Alternatives represent what the participants are choosing between. Criteria are used to judge the alternatives. Each criterion contains an importance value. Each link between nodes also contains an importance value. The system estimates a ranking list of alternatives among participants from each map. We introduce a forgetting function to the model. The system also supports the decision-making process by using discussion maps from participants. It generates sentences and charts that describe the current state of the discussion. We evaluate the effectiveness of the discussion map system with DMA in a decision-making task experimentally.
