Dynamic Topic Modeling of Covid-19 Vaccine-Related Tweets

Published: 24 June 2022 Publication History

Abstract

The Covid-19 pandemic has made a huge impact on the world. Vaccines are regarded as the universal solution to mitigate the spread of the pandemic. Vaccination programs have been initiated by all countries in the past one year or so. The public opinion about vaccinations has been dynamically changing during this period. We intend to track the perception of the masses since the arrival of the vaccines, through social media posts, and reflect on the reasons behind the dynamically evolving ideas of people. For this purpose, we propose the use of Latent Dirichlet Allocation (LDA) for topic modeling from vaccine-related discussions on the popular social media platform Twitter, in five temporal phases, in the duration of 20 December 2020 to 16 October 2021. The time windows are determined such that the tweets are equally distributed in each time slice. The ten most relevant terms in the top-10 topics in each time window are determined and presented in the form of bar charts. The relevancy of a term is interpreted as the sum of probabilistic scores associated with that term in the top-10 topics identified by LDA in a particular time period. The bar charts are further analyzed for inferring the topics of discussion in a particular phase of time.
