Outline of Final Research Achievements

We developed a machine learning method for crowdsourcing professional decisions. (1) We developed a method for building consensus among professionals with diverse decision criteria. (2) We developed a method to estimate student proficiency by using results of peer-grading and peer-correction. (3)We developed an efficient collaborative learning method by letting students learn from answers of others.

Academic Significance and Societal Importance of the Research Achievements

自動化が進み様々なプロセスが効率化される中で人間による判断がボトルネックとなることが多い。本研究成果は、専門家の集団意思決定の効率化や、非専門家による専門的な判断の実現に貢献する。特に後者により、専門的判断が増える人材が拡大することで、クラウドソーシングを通じて、専門的判断の教師データを大量に収集しそれを模倣した機械学習モデルを構築することができるようになる。つまり、専門的判断を実現する人工知能の開発に貢献する。
