Field Weighted Citation Impact (FWCI) Information

Category: Article Level


Definition: The ratio of the total citations a document has actually received by the denominator's output, and the total citations that would be expected based on the average of the subject field. A FWCI of 1 indicates that the document has performed just as expected for the global average. A FWCI of greater than 1 indicates that the document is more cited than expected according to the global average (Ex. 1.48 means 48% more cited than expected).


Use case: The FWCI facilitates the benchmarking of citation performance across groups of different size, disciplinary scope and age, such as research large groups, institutions, or geographic regions.


Location: Scopus (SciVal)


Field Normalized?  Yes


Caveats:  Only available for documents indexed in Scopus.


Sample Statement: This 2020 editorial by Dr. Fauci has a field weighted citation impact of 157.70, indicating it is 157 times more cited than expected (Scopus). 

What that means: The actual number of citations that Dr. Fauci’s editorial received is significantly higher than the average expected for a document published in his field at the same time.
