Eigenfactor and article influence scores in the Journal Citation Reports
Abstract
Purpose
This sequel to the earlier testing and evaluation of the five‐year Journal Impact Factor (JIF‐5) in the enhanced version of the Journal Citation Reports (JCR) (released in January and July 2009 for the 2007 and 2008 journal collections, respectively) seeks to assess and compare the impact on the ranking of journals by two other performance indicators.
Design/methodology/approach
Both the Eigenfactor Score (EFS) and the Article Influence Score (AIS) use a five‐year target window in the algorithm to quantify the scholarly impact at the overall journal level and at the article level, respectively.
Findings
The paper examines how the rank positions of 52 library and information science journals change when the set of journals are ranked by the Eigenfactor metrics in relation to the JIF‐5 indicator.
Originality/value
The principle behind Google's PageRank is where a web page or site got ranked in the search results based not merely on the number of incoming links, but also on the status/prestige of the linking sites based on the PageRank scores of those linking sites. This is a recursively calculated permanent value until the next year's edition.
