Analyzing the vast coronavirus literature with CoronaCentral

The SARS-CoV-2 pandemic has caused a surge in research exploring all aspects of the virus and its effects on human health. The overwhelming publication rate means that researchers are unable to keep abreast of the literature. To ameliorate this, we present the CoronaCentral resource that uses machine learning to process the research literature on SARS-CoV-2 together with SARS-CoV and MERS-CoV. We categorize the literature into useful topics and article types and enable analysis of the contents, pace, and emphasis of research during the crisis with integration of Altmetric data. These topics include therapeutics, disease forecasting, as well as growing areas such as “long COVID” and studies of inequality.

 

The COVID-19 pandemic has led to the greatest surge in biomedical research on a single topic in documented history (Fig. 1A). This research is valuable both to current and future researchers as they examine the long-term effects of the virus on different aspects of society. Unfortunately, the vast scale of the literature makes it challenging to navigate. Machine-learning systems that can automatically identify topics and article types of papers would greatly benefit researchers who are searching for relevant coronavirus research.
