Connections between terms with few publications, those unconnected to the main network and those irrelevant were not displayed. Nodes were coloured by knowledge base and the size of the node related to the number of publications containing the term. The data set and visualisations were made publicly accessible via a webtool.Conclusion Knowledge management approaches (text mining and graph networks) can effectively allow rapid navigation and exploration of entity inter-relationships to improve understanding of diseases such as COVID-19.}, URL = {https://informatics.bmj.com/content/28/1/e100254}, eprint = {https://informatics.bmj.com/content/28/1/e100254.full.pdf}, journal = {BMJ Health \& Care Informatics} }
