| 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.
