Abstract
The status of an actor in a social context is commonly defined in terms of
two factors: the total number of
endorsements the actor receives from other actors and the prestige of the
endorsing actors. These two factors
indicate the distinction between popularity and expert appreciation of the
actor, respectively. We refer to the
former as popularity and to the latter as prestige. These notions of
popularity and prestige also apply to the
domain of scholarly assessment. The ISI Impact Factor (ISI IF) is defined
as the mean number of citations
a journal receives over a 2 year period. By merely counting the amount of
citations and disregarding the
prestige of the citing journals, the ISI IF is a metric of popularity, not
of prestige. We demonstrate how a
weighted version of the popular PageRank algorithm can be used to obtain a
metric that reflects prestige. We
contrast the rankings of journals according to their ISI IF and their
weighted PageRank, and we provide an
analysis that reveals both significant overlaps and differences.
Furthermore, we introduce the Y-factor which is
a simple combination of both the ISI IF and the weighted PageRank, and find
that the resulting journal rankings
correspond well to a general understanding of journal status.
