Twitter is a famous social networking service and has received attention recently. Twitter user have increased rapidly, and many users exchange information. When 2011 Tohoku earthquake and tsunami happened, people were able to obtain information from social networking service. Though Twitter played the important role, one of the problem of Twitter, a false rumor diffusion, was pointed out. In this research, we focus on a false rumor diffusion. We propose a information diffusion model based on SIR model, classify the way of diffusion in four categories, and reapper the real diffussion by using this new model.

災害時情報共有のためのプロトコル、およびそのプロトコルを扱うサーバシステムを提案する。災害時において情報共有をいかに行うかは迅速な災害対応を行う上で重要であるが、実際の災害現場では紙ベースあるいは閉鎖的なシステムによる情報管理が行われており、十分な情報共有が行なわれていない。提案するシステムは、プロトコルとしてオープンな標準規格を用い、既存システムを柔軟に接続する事ができる。
