| Outline of Final Research Achievements |
In order to achieve stable operation of the information network, it is important to know the structure of the network where users exchange information. However, it is difficult to analyze the detailed structure of the user’s network due to its large scale and complexity. In this research, we first show how to indirectly estimate the structure of a social network that can not be observed directly. We also consider a model to describe the propagation of activity on the network and clarify the difference from the conventional network analysis method. Furthermore, we consider a model that makes it possible to engineeringly understand the occurrence mechanism on the flaming of SNS. We also analyze the information propagation characteristics of large social networks using the universal nature of random matrices.
