Monitoring Misinformation on Twitter During Crisis Events: A Machine Learning Approach

Abstract: Social media has been increasingly utilized to spread breaking news and risk communications during disasters of all magnitudes. Unfortunately, due to the unmoderated nature of social media platforms such as Twitter, rumors and misinformation are able to propagate widely. Given this, a surfeit of research has studied false rumor diffusion on Twitter, especially during natural disasters. Within this domain, studies have also focused on the misinformation control efforts from government organizations and other ma… Show more

“…22 Of note, this report suggests that the rates of infection in NHS staff are not as high as some previous estimates reported from England, notably social medial reports of seroprevalence up to 60%. 23 Studies have estimated seroprevalence to be between 15% and 45% in HCWs in patient-facing roles and 3%-25% overall. 21 24-26 These rates are thought to vary by specialty, 27 but the infection rates between different subgroups vary by report.…”

“…In related works a variety of the machine learning algorithms applied on tweets from multiple different events to monitor multiple cases of misinformation simultaneously. From the results of this work the model accuracy of various algorithms such as k-Nearest neighbourhood and Support Vector Machines proved efficient for the purpose [18]. In another work a COVID-19 news verification system developed based on three tier system developed (CoVerifi), a frontend based on React.js, a backend based on Python Machine Learning services and a database storing [19].…”

“…Covid-19 vaccines, behaviours against them, etc) are already starting to increase and healthcare informatics applications are becoming a very useful tool of defence [7]. Previous works proved that "Machine Learning" application seems very useful in recognising and striking out fake news and other disinformation [8,9,10].…”
