Topic Models to Interpret MeSH – MEDLINE’s Medical Subject Headings

We show how topic models are useful for interpreting and understanding MeSH, the Medical Subject Headings applied to articles in MEDLINE. We show how our resampled author model captures some of the advantages of both the topic model and the author-topic model. We demonstrate how the topic modeling approach can provide an alternative and complementary view of the relationship between MeSH headings that could be informative and helpful for people searching MEDLINE.
