Identifying and Grouping Crisis-Related Social Media Posts for Disaster Response

Every year, within a specific timeframe, human society
confronts challenges arising from natural calamities. The ultimate
result of a natural crisis, such as flooding, hurricanes, earthquakes,
and tsunamis, is the disruption of communication with the outside

after a crisis has occurred. Once the situation arose, the first two
barriers were the breakdown of the power supply and
communication to the outside world. Even though mobile
communication is available, information is often obtained orally for
a particular person, and this can lead to failure due to incorrect
communication with the wrong number or the unavailability of the
receiving party. Due to the introduction of smartphones and
Online Social Networks (OSNs), information has been disseminated

signal strength. Many people will see the posting and become aware
of the situation in a particular area. This paper proposes a
framework for identifying crisis-related posts with diverse topics
and grouping them to disseminate information to responders,
thereby facilitating a faster recovery process. A virtual group has
been formed, comprising both requesters and responders of the

for their need. The performance of the pr
