Process Descripiton
The process is composed mainly from 3 modules:
Data Collection: It concerns the collection of facebook public posts focused on the context of the pandemic based on a multlingual vocabulary centerd COVID-19. It includes also a routine for updating teh data after extracting the infromation from active users pertaining to a great range of countries.
Multilingual Topic Modelling: It includes a step of pre-teratment for preparing the gathered data. Then, we applied the LDA (Latent Dirichlet allocation) topic modelling method for extracting the COVID-19 related trends through the time from the January 1st, 2020.
Results presentation: We propose a novel way for presenting the topic modelling results based on graph structure.
