Outline of Final Research Achievements

The trust network model was extended to include location information and sensor data to handle intimacy between people, space, and objects. We then developed a model and method for extracting trust networks based on real-world context and recommending information and information providers. We also developed a prototype based on the proposed method and conducted experiments. The experimental results are summarized as findings that can be referred to when conducting trust management with living trust networks. The possibility of applying the proposed method to recommendation to learners was also discussed.

Academic Significance and Societal Importance of the Research Achievements

生きた信頼ネットワークの実現は、国際的にみても独自性の高い取り組みであり、理論・実践の両面で有意義な研究成果が得られた。フェイクニュース等が社会の大きな問題となりその解決策が求められるところであるが、本研究の成果は、実世界コンテクストのデータを駆使して、信頼できる情報や情報提供者を従来よりも容易に見つけることのできる環境の実現につながるものである。
