Outline of Final Research Achievements

We will clarify the process of formation and transformation of social capital called third social capital which supports knowledge creation society for real and cyber complex space. We proposed an innovative method to extract the tweets which will support the real life in some aspects of life. By focusing on the node function of the community graph, we also proposed a centrality indicator that represents structural characteristics and semantic characteristics.
According to rapidly expanding text communication, we also proposed a method to estimate the role and intimacy of the speaker. We also devised both a machine learning method for sequence data for dealing with change transformation, and considering the intention estimation at the time of text posting and feature quantities effective for opinion analysis.
