How do you in bibliometrics decide the subject of a publication?

There are presently two ways that we can identify the research fields of individual articles. One is to use the Clarivate Analytics journal subject field as a proxy for article content. This is very often used in bibliometric studies. But in medicine, many of the publications also have MeSH terms, the controlled vocabulary from Medline, which are much more specific, and at Karolinska Institutet we often use these.

For publications in the intersection between the Web of Science and Medline, both citation data and detailed subject information at an article level are available. At Karolinska Institutet we often use this type of intersection to single out publications in Medicine and Life Science from all Web of Science records from other research institutions. This makes it possible to do better comparative analyses between us, as a medical university, and research institutions with more than one faculty.
