Extension of the Disaster Information Sharing System DITS & DIMS to a System Available on a Daily Use

Abstract

To collect and spread accurate information quickly is vital to minimize the damage caused by disasters. Then, the utilization of social media during disasters has been gaining attention. Based on such background, we developed a Twitter-based disaster information sharing system called DITS (disaster information tweeting system) & DIMS (disaster information mapping system) in previous studies. Using DITS, we can post and share disaster-related tweets with location information and the appropriate hashtags with simple operations. Furthermore, we can view the information posted using DITS on a map with DIMS. However, there is concern that if the system can only be used in disasters, it will not be adequately utilized when one occurs. The study then expanded DITS & DIMS into a system that can be used for more than just disasters, that is, to share daily local information, such as tourist and gourmet information. This study also changed the system to make it more usable.
