Abstract

Up to October 13, 2020, 37,948,577 cases of Corona Virus Disease 2019 (COVID-19) have been reported worldwide (1080,619 deaths), and there is a further development trend. The problems reflected in this epidemic have made biosafety and biosecurity (hereafter collectively referred to as "biosafety") once again a hot topic of discussion in the international community. Biosafety covers a wide range, and it is very important to be able to quickly retrieve biosafety hotspots and trends from massive data. We designed and constructed a novel model LDAPR to extract topics from the abstracts of biosafety-related papers from 2011 to 2020, and we conducted hotspot and trend analysis on the results of LDAPR. At the same time, we have carried out further research on the connections of these topics, and these connections will provide inspiration for further research.
