“…Decision makers’ challenges include identifying people’s sentiments on a subject and their beliefs ( Zarrad, et al, 2014 ) towards public health policy decision-making ( Chung, et al, 2015 ; S. Li et al, 2020 , Lwin et al, 2020 ) in extremely serious cases, such as disease outbreaks ( Chung, et al, 2015 ). In addition, this dilemma will challenge decision makers to take serious measures without delay ( Ji, et al, 2015 ) and control the spread of an event or even quarantine confirmed cases of infectious diseases ( Bhat et al, 2020 , Choi et al, 2017 , Ji et al, 2013 , Singh et al, 2018 ). Aside from decision makers, the scientific community has an equally important role in fighting these outbreaks via sentiment analysis; however, fully utilising the abilities of the community remains elusive because of a lack of scientific reference work ( Chung, et al, 2015 ), the availability of studies in certain languages only ( Baker, et al, 2020 ) or the absence of relevant research with the latest trends ( Ji, et al, 2015 ).…”
