| Abstract: |
This paper examines the practical usefulness of two new journal performance
metrics, namely the Eigenfactor score, which may be interpreted as measuring
“Journal Influence”, and the Article Influence score, using the Thomson
Reuters ISI Web of Science (hereafter ISI) data for 2009 for the 200 most
highly cited journals in each of the Sciences and Social Sciences, and
compares them with two existing ISI metrics, namely Total Citations and the
5-year Impact Factor (5YIF) of a journal (including journal self citations).
It is shown that the Sciences and Social Sciences are different in terms of
the strength of the relationship of journal performance metrics, although the
actual relationships are very similar. Moreover, the journal influence and
article influence journal performance metrics are shown to be closely related
empirically to the two existing ISI metrics, and hence add little in practical
usefulness to what is already known. These empirical results are compared with
existing results in the literature. |
