Web of Science – Clarivate Analytics measures a journal’s impact based on the number of article citations compared to the total number of articles published. The impact factor—a quantitative measure of the frequency with which an article in a journal is cited—is used to gauge the overall influence of a journal within scientific, professional and academic communities.

The impact factor is often used as a measure of the quality and influence of medical journals among researchers. For more than 45 years, Thomson Reuters has provided a systematic and objective way for librarians, researchers and other decision-makers to measure influence in the global research community.”

The Journal Citation Report also publishes several other measurements for journals, including the total citations, immediacy index, and five-year impact factor.
