Field-Weighted Citation Impact (FWCI)

Category-Normalized Citation Impact (CNCI)

Calculated by dividing the actual count of citing items by the expected citation rate for documents with the same document type, year of publication and subject area.

A CNCI of 1 represents performance at par with world average, values above 1 are considered above average and values below 1 are considered below average.
