Article-level metrics attempt to assess how a sinlge article is used and shared. 

Availability of Article-Level Metrics varies between platforms and publishers. 

Some platforms and publishers attempt to normalize article use for subject and year published.

Common counts include:

• Citation Count

  • the number of times an article is cited in other bodies of literature

  • Inconsistent when you compare it from database to database

• Field Weighted Citation Impact (FWCI)

  • Only available for documents indexed in Scopus

  • 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).

• Relative Citation Ratio

  • Used to compare NIH funded work to other NIH funded work

  • located in iCite

  • Represents a citation-based measure that is calculated as the cites/year of each paper, normalized to the citations per year received by NIH-funded papers in the same field and year.
