Abstract
Organizations that are responsible for disaster and emergency management are
faced with the issue of how to gather
reliable and useful information during a major disaster. We consider an information gathering platform for
large-scale disasters and emergencies based on mobile terminals. A simple solution to realize an
information-gathering system is to construct a server where information is uploaded and
published. However, such a centralized approach is not flexible nor is it
robust. For
example, it is very hard to find an appropriate system to which the user can
upload information during a disaster, and
the centralized server may be down because of overload or because it has been physically
destroyed. We must consider a distributed and dynamic architecture for the
system. Security
and privacy issues are another concern that should be addressed for providing
information from user¡¯s mobile
terminals. Here, we focus on the design of a categorization mechanism for the information-gathering
system. In this paper, we present a mechanism that has been designed so that it is able to
accommodate requirements and we then conduct a feasibility analysis of the
mechanism.
