SenWave: Monitoring the Global Sentiments Under the COVID-19 Pandemic


Since the first alert launched by the World Health Organization (5 January, 2020), COVID-19 has been spreading out to over 180 countries and territories and caused over 30M infected cases and 900K related deaths, as of 23 September 2020. This causes massive losses in the economy and jobs globally and confining about 58% of the global population. In this talk, we introduce SenWave, a novel sentimental analysis work using 105+ million collected tweets and Weibo messages to evaluate the global rise and falls of sentiments during the COVID-19 pandemic, including optimistic, thankful, empathetic, pessimistic, anxious, sad, annoyed, denial, official report, and joking. SenWave reveals the sentiment of global conversation in six different languages on COVID-19 (covering English, Spanish, French, Italian, Arabic and Chinese), followed the spread of the epidemic. The conversation showed a remarkably similar pattern of rapid rise and slow decline over time across all nations, as well as on special topics like the herd immunity strategies, to which the global conversation reacts strongly negatively. Overall, SenWave shows that optimistic and positive sentiments increased over time, foretelling a desire to seek, together, a reset for an improved COVID-19 world.
