Limitations of network-based approaches in the face of the emerging new infectious disease. a New disease (COVID-19) cannot be connected with the knowledge network using data collected before emerging COVID-19. b Although the novel associations related to COVID-19 can discover by researchers over time, the final network for drug repurposing can differ depending on the selected dataset. c We developed a new method of updating the network instantly with the complementary dataset (discovered findings from studies) to find candidate repurposable drugs for COVID-19
