Feedback-based social media filtering tool for improved situational awareness

Logística Humanitária: Tecnologias Digitais De Comunicação Na Gestão De Riscos De Desastres

“…Assim sendo, será sempre imprescindível filtrar as informações que são publicadas e compartilhadas nas mídias, durante a ocorrência de desastres ou emergências, a fim de identificar erros, eliminar notícias falsas e, ainda, suprimir termos ou palavras que possam causar confusão à população em risco (Thornton;Deangelus;Miller, 2016).…”

Improved healthcare disaster decision-making utilizing information extraction from complementary social media data during the COVID-19 pandemic

“…[ 5 , [19] , [20] , [21] , [22] ]. Only a few papers like [ 4 , [23] , [24] , [25] ] are independent of a specific disease. Most literature on this field relies on information extraction from text, while only a few works like [ 25 ] also integrate information extraction from images.…”

“…Only a few papers like [ 4 , [23] , [24] , [25] ] are independent of a specific disease. Most literature on this field relies on information extraction from text, while only a few works like [ 25 ] also integrate information extraction from images. Additionally, a majority of literature incorporates microblogging platforms like Twitter, e.g., [ 3 , 4 , 9 , 26 , 27 ], and Sina Weibo [ 21 , 28 , 29 ].…”

“…When it comes to the methodology, most papers perform a classification task, e.g., to detect misinformation or rumors [ 12 , 30 ] or analyze online behavior on social media (e.g., sentiment analysis [ 27 , 31 ], public attention [ 28 , 32 ], or information diffusion [ 9 ]). Furthermore, several papers conduct topic modeling using social media [ 3 , 19 , 25 , 33 ], and incorporate geospatial information in their analysis (e.g., to disclose the spread of a disease) [ 3 , 21 , 24 , 34 ] .…”

“…In order to analyze UGC, researchers use various advanced statistical and computational techniques. Especially NLP seems to be a critical method when investigating UGC [ 2 , 20 , 21 , 24 , 25 ]. The broad adoption of NLP mainly stems from the fact that social media often provides information in unstructured text.…”
