ADDITIONAL REFERENCE MATERIAL
—
Eigenfactor score reflects a journal’s footprint in the overall journal-citation
network, measuring its influence in the entire network. It is based on the
Google PageRank method.
Journal C has a
higher PageRank or
“weight” than Journal
E, even though it has
fewer links citing it;
the one cite it does
have is of a much
higher value.
From Wikipedia
– “PageRank”
EIGENFACTOR SCORE
— NORMALIZED EIGENFACTOR SCORE
Normalized Eigenfactor
Score: a value of 1 indicates
average influence. A higher
value indicates above average
influence
WHY NORMALIZE?

Percentile in subject area
smaller is better — in this example 0.04% of the papers in the
category (plant sciences) in 2014 had more citations
ACCOUNT FOR FIELD, AGE, AND DOCUMENT TYPE
Average percentile
for a group of papers, we average all of the documents’
percentiles
