讲座内容

This webinar will talk about discussions of Covid-19 on Twitter, summarizing four studies and emphasizing the methods used to investigate Twitter. The first (Thelwall & Thelwall, 2020) identifies Covid-19 related themes that resonated on English language Twitter by investigating the most retweeted topics. Popular tweets in the strange situation of the first lockdowns helped build support for social distancing, criticized governments, supported key workers, supported others through social isolation. The second (Thelwall, 2021a) reports a retrospective analysis of the level of interest in Covid-19 vaccines on Twitter, showing that the Pfizer-BioNTech phase 3 trials results were the key event that converted this from a minor to major issue. The third (Thelwall et al., 2021) investigates how Covid-19 vaccine hesitancy was expressed up to 5 December 2020, finding that it was mostly tweeted about by right-wingers, with some exceptions. The final paper (Thelwall, 2021b) found international differences in English language tweeting about Covid-19 vaccinations from 5 December 2020 to 21 March 2021. Not all countries had prominent unofficial experts providing commentary and the concept of vaccine kindness (#VaccineMaitri) was only expressed in India. The talk will explain how Twitter became much easier to research at the start of 2021 when academics were allowed free access to historical tweets. It will discuss the word association thematic analysis method (Thelwall, 2021c) used to identify key themes within large collections of tweets from this source.
