| Outline of Final Research Achievements |
We investigate analysis of contents posted by users of SNSs, and users’ motivations on SNS posting. From Wikipedia edit histories, we developed an efficient and accurate algorithm to reconstruct version histories, which can indicate how branches of versions were happened, for illustrating the process of the evolution of articles. We asked Facebook users about their motivations on their postings, and developed a purpose model that can classify into major purposes, including interaction between new online friends and interaction with known friends, and then discovered predictors of these purposes from users’ profiles and metrics on posting behaviors.
