Abstract


AbstractDisasters have enormously disrupted the normal way of life of countries around the world and the Philippines is one of these countries. It is one of the most badly hit by disasters every year and due to its lower coping capabilities, it has constantly been ranked in the top 10 of the World Risk Index. This paper proposes a text mining framework that classifies and prioritizes disaster-related social media data, particularly Twitter tweets for the use of disaster managers for disaster response decision making. Validation of the framework during the classification stage resulted in an average of 90.67%, 99.25%, and 72.84% recall, on the test cases pertaining to training data and two different typhoon datasets. The prioritization module also prioritized tweets that were deemed urgent indicating the need for immediate response or attention.
