Verification of Consensus Building Support System on Large-Scale Social Experiment where Celebrities Participate in Discussion

Abstract

We have developed the consensus building support system called COLLAGREE on the Web with facilitator support function. If discussions are conduct by free participation on the Web, celebrity may participate. Therefore, in this work, we conduct large scale social experiments using support systems where celebrities participate. The purpose of this work is to verify the effectiveness and problems of consensus building support system in discussion where celebrities participate. IN the large-scale social experiments, we clarified that new threads by celebrities' increases the number of reply and approval number by about 3 times compared to other participants. Also, we clarified that opinion by celebrities did not little affect voting results. Furthermore, we clarified that participants were not influenced by celebrity opinions, but were influenced by other participants.
