Abstract

During the last years, many computer systems have been developed to track and monitor COVID-19 social network interactions. However, these systems have been mainly based on robust probabilistic approaches like Latent Dirichlet Allocation (LDA). In another context, health recommender systems have always been personalized to the needs of single users instead of regional communities. Such applications will not be useful in the context of a public health emergency such as COVID-19 where general insights about local populations are needed by health policy makers to solve critical issues in a timely basis. In this research paper, we propose to modify LDA by letting it be driven by knowledge resources and we demonstrate how we can apply our topic modeling method to local social network interactions about COVID-19 to generate precise topic clusters reflecting the social trends about the pandemic at a low cost. Then, we outline how terms in every topic cluster can be converted into a search query to generate scholarly publications from PubMed Central for adjusting COVID-19 trendy thoughts in a population.
