Title (up) Understanding patterns and mood changes through tweets about disasters Type Conference Article
Year 2019 Publication Proceedings of the 16th International Conference on Information Systems for Crisis Response And Management Abbreviated Journal Iscram 2019
Volume Issue Pages
Keywords Disaster, Pattern, User Classification, Mood Detection, Twitter
Abstract We analyzed a sample of large tweet collections gathered since 2011, to expand understanding about tweeting

patterns and emotional responses of different types of tweeters regarding disasters. We selected three examples for

each of four disaster types: school shooting, bombing, earthquake, and hurricane. For each collection, we deployed

our novel model TwiRole for user classification, and an existing deep learning model for mood detection. We

found differences in the daily tweet count patterns, between the different types of events. Likewise, there were

different average scores and patterns of moods (fear, sadness, surprise), both between types of events, and between

events of the same type. Further, regarding surprise and fear, there were differences among roles of tweeters. These

results suggest the value of further exploration as well as hypothesis testing with our hundreds of event and trend

related tweet collections, considering indications in those that reflect emotional responses to disasters.

Title (up) When Official Systems Overload: A Framework for Finding Social Media Calls for Help during Evacuations Type Conference Article
Year 2019 Publication Proceedings of the 16th International Conference on Information Systems for Crisis Response And Management Abbreviated Journal Iscram 2019
Volume Issue Pages
Keywords Disasters, social media, hurricanes, data, framework, public safety
Abstract During large-scale disasters it is not uncommon for Public Safety Answering Points (e.g., 9-1-1) to encounter

service disruptions or become overloaded due to call volume. As observed in the two past United States hurricane

seasons, citizens are increasingly turning to social media whether as a consequence of their inability to reach

9-1-1, or as a preferential means of communications. Relying on past research that has examined social media

use in disasters, combined with the practical knowledge of the first-hand disaster response experiences, this paper

develops a knowledge-driven framework containing parameters useful in identifying patterns of shared

information on social media when citizens need help. This effort explores the feasibility of determining

differences, similarities, common themes, and time-specific discoveries of social media calls for help associated

with hurricane evacuations. At a future date, validation of this framework will be demonstrated using datasets

from multiple disasters. The results will lead to recommendations on how the framework can be modified to make

it applicable as a generic disaster-type characterization tool.
