The following metrics and indicators are used with publications and other content types in Dimensions:

Publication citations

Recent citations

The recent citations value is the number of citations that were received in the last two years. It is currently reset at the beginning of each calendar year.

This includes mentions in public policy documents and references in Wikipedia, the mainstream news, social networks, blogs and more. Find out more about the weightings of each source and how they contribute to the attention score.

Relative Citation Ratio (RCR)

The Relative Citation Ratio (RCR) indicates the relative citation performance of an article when comparing its citation rate to that of other articles in its area of research. A value of more than 1.0 shows a citation rate above average. The article’s area of research is defined by the articles that have been cited alongside it. The RCR is calculated for all PubMed publications which are at least 2 years old.

Field Citation Ratio (FCR)

The Field Citation Ratio (FCR) is an article-level metric that indicates the relative citation performance of an article, when compared to similarly-aged articles in its subject area. A value of more than 1.0 indicates higher than average citation, when defined by Field of Research Subject Code, publishing year and age. The FCR is calculated for all publications in Dimensions which are at least 2 years old and were published in 2000 or later.

Patent citations

Patent citations is the number of times that this record has been cited by other published patents. Patents may be registered in several offices, and this may effect patent citation data.
