Seventeen participants attended the presentation by Dr Diana Contreras on the 17th World Conference in Earthquake Engineering (17WCEE) entitled: Assessing Post-disaster Recovery Using Sentiment Analysis (SA). The cases of L'Aquila (Italy), Chile and Haiti. The presentation took place on the 2nd October 2021 at 9:15 (JST), 1:15 (BST), 2:15 (CET) during Session O02A11:Post Disaster Assessment and Computational Science. Professor Colin Taylor from the University of Bristol asked about tweet data and if the team has used the data coming from Twitter for other kinds of events different to post-disaster recovery to calibrate the classification model.
Dr Diana Contreras explained that Twitter data is classified according to their polarity to determine the success of the post-disaster recovery. To the second question, she answered that besides post-disaster recovery, the team at Newcastle University had explored the use of Twitter data and text data provided by the European-Mediterranean Seismological Centre (EMSC) collected from the LastQuake app' users to also assess emergency response and early recovery after earthquakes.
