A stacked convolutional neural network for detecting the resource tweets during a disaster

Abstract: Social media platform like Twitter is one of the primary sources for sharing real-time information at the time of events such as disasters, political events, etc. Detecting the resource tweets during a disaster is an essential task because tweets contain different types of information such as infrastructure damage, resources, opinions and sympathies of disaster events, etc. Tweets are posted related to Need and Availability of Resources (NAR) by humanitarian organizations and victims. Hence, reliable methodolo… Show more

“…While this progress on food security is valuable, future work can be improved upon by taking guidance from other fields that have made progress on identifying needs and resources on microblogs, even though they are not explicitly focused on food. [42][43][44][45][46][47][48] Recent studies have improved performance of classifying needs and resources through the use of key terms mapped to crisis scenarios and the general detection of needs and resources. 49 This includes crisis-related lexicons, e.g., EMTerms 50 and CrisisLex 51 , that contain over 7,000 terms used in Twitter to describe various crises.…”

“…Similarly, Purohit et al [9] attempted to prioritize the requests made by the affected people to be serviced by the emergency responders. In a recent study by Madichetty et al [41], authors filtered 'Need and Availability Resources (NAR)' tweets from the Nepal and Italy earthquakes that happened in 2015 and 2016, respectively, using a stacked architecture of CNN with traditional classifiers. Their experiments on various classifiers confirm that K-Nearest-Neighbor as the base classifier, Support Vector Machine as the meta classifier, and CNN give the best results.…”

“…Madichetty has focused informative tweets identification of natural disasters, and Sridevi (2020c) [21] are examined the model using SVM (meta classifier) and KNN (base classifier) with the combination of CNN outperforms the other algorithms The Deep Learning models (CNN, LSTM, BLSTM, and BLSTM attention) are used to identify situational information during a disaster in Hindi language tweets, besides English language tweets. Deep learning model results outperform existing classic disaster-set approaches, such as Hagupit cyclone, Hyderabad bomb blast, Sandhy shooting, Harda rail accident, and Earthquake.…”
