In some bibliometric databases that ‘count’ may be contextualised by a percentile or Field-Weighted Citation Impact (FWCI) comparison with similar documents.
For example, the Scopus database has counted 380 citations for the following article, it is in the 99th percentile and it has a Field-Weighted Citation Impact of 9.73, when compared with similar documents.
At the document level Dimensions uses the Field Citation Ration (FCR) The FCR indicates the relative citation performance of a publication 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 (FoR) subject code, and publication year. Dimensions also has a Relative Citation Ratio (RCR) metric for articles published in PubMed. Search for the article and click on the Dimensions Badge for additional information about the article.
