Figure 1.

The column to the left shows the list of new concepts resulting from the inclusion of the last item in the list of “Selected Concepts”. A part of the results is shown to the right and shows one of the categories (“Diagnostic Procedure”) and the related concepts. Each related concept has a link to the relevant articles in the CORD-19 Dataset, and each is ranked by relevance to COVID-19 (depicted by blue bars on the right), where relevance is represented by log probability (or negative log likelihood loss) of the strength of the concept relationship to COVID-19, according to the WellAI neural networks.
