... of autoimmune disease research. The goal of this paper is to provide insight into the most popular research topics associated with 8,470 NIH autoimmune disease research grant abstracts using latent dirichlet allocation (LDA)
From page 510...
... . Given a set of 8,470 NIH research grant abstracts related to autoimmune diseases that were funded between 2008 and 2020, topic modeling using LDA was implemented to discern which topics are prevalent within the abstracts.
From page 511...
... Table H-1 lists the final topic names; some topics were given the same topic name because they were deemed too similar, and their topic assignments were combined in the later plots. Final Results One of the outputs of the LDA model is the theta matrix, which shows the proportion of topics assigned to each abstract.
