| Outline of Final Research Achievements |
In this study, we investigated the mathematical properties of "spiral-of-silence = threshold model", and developed the methods for applying to actual event data. Then we analyzed the real event data with this model, and examined its effectiveness and limit.
Also, for the purpose of grasping people's recognition of their situations in today's diversified communication environment, We investigated it by applying techniques developed in computer science / machine learning field. The result are that (1)On-line systems where discourses are generated and distributed greatly affects the discourses and the whole situation of the systems is determined, (2)people's perception of the whole situation depends on the contexts in which they are placed.
