Information filtering for emergency management

Information filtering is a function to select useful or interesting information for the user among a large amount of information. This function has become very important as network technology develops rapidly. This paper focuses on information filtering for emergency management. We believe that special purpose "information filtering system" should be developed to cope with the problem of information flood in emergency management. In this paper, we first investigate the features of information in emergency situations. Then we propose an information filtering system for emergency management, and evaluate it by computer simulation.
