DisasterAlert: Disaster Alert and Sentiment Analysis
By systematically aggregating and processing textual reports from earthquakes, floods, storms,
wildfires, and other natural disasters, the framework enables a holistic assessment of crisis narratives.
Intelligent cleaning and normalization techniques transform raw commentary into structured data, ensuring
precise extraction of disaster-specific insights. Collective sentiments of affected communities are
quantitatively scored and qualitatively categorized, providing a multifaceted view of societal responses
under duress. Interactive geographic maps and temporal charts illustrate the evolution and spatial dispersion
of emotional reactions and impact indicators.
