Journal Citation Indicator
The Journal Citation Indicator (JCI) is a measure of citation impact that is normalized by subject category. It is calculated using citations from items published in the JCI year and prior three years, to items published in the prior three years. Because of the category normalization, a score of 1 means that articles in a journal received a number of citations equal to the average citation count in that subject category.
