Concepts (347)

Concept scores are derived automatically based on a person's publications. Keywords in the their attributed publications are matched to keywords from the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings). The strength of a person's concept scores is based not only on the number of corresponding publications, but also how relevant the concepts are to the overall topics of the publications, how long ago the publications were written, whether the person was the first or senior author, and how many other people have written about the topic.Concepts cannot be directly edited. You can help ensure your concepts are accurate by making sure your attributed publications are correct and up-to-date. We recommend checking over your attributed publications list every three to four months.
