摘要：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 up- loaded and published. However, such a centralized approach is not .exible nor is it robust. For example, it is very hard to find an appropriate system to which the user can upload information dur- ing 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. Se- curity 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
