Abstract

fetched live from OpenAlex

This paper presents our research on leveraging social media Big Data and AI to support hurricane disaster emergency response.The current practice of hurricane emergency response for rescue highly relies on emergency call centres.The more recent Hurricane Harvey event reveals the limitations of the current systems.We use Hurricane Harvey and the associated Houston flooding as the motivating scenario to conduct research and develop a prototype as a proof-ofconcept of using an intelligent agent as a complementary role to support emergency centres in hurricane emergency response.This intelligent agent is used to collect real-time streaming tweets during a natural disaster event, to identify tweets requesting rescue, to extract key information such as address and associated geocode, and to visualize the extracted information in an interactive map in decision supports.Our experiment shows promising outcomes and the potential application of the research in support of hurricane emergency response.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
