| Outline of Final Research Achievements |
This research clarifies the transition from feature phones to smartphones in mobile. This research reveals discontinuity from referential relationships. And then we examines discontinuity with topic analysis which is a method of calculating appearance rate in text-mining.
Using topic analysis, in 16 topics (in 43 topics), we clarified obvious differences of appearance rate. On the other hand, in 27 topics, we can not clarified differences.
From these results, we can find discontinuity and continuity in the transition from feature phones to smartphones.
