Eigenfactor Score and Motion Charts

Eigenfactor Score

The Eigenfactor came out of the Metrics Eigenfactor Project in 2008, a bibliometric research project conducted by Professor Carl Bergstrom and his laboratory at University of Washington.

The Eigenfactor score provides a measure of journal importance.

With all else equal, a journal's Eigenfactor score doubles when it doubles in size. Thus a very large journal such as the Journal of Biological Chemistry which publishes more than 6,000 articles annually, will have extremely high Eigenfactor scores simply based upon its size.

The Eigenfactor Score measures the number of times articles from the journal published in the past five years have been cited in the JCR year.

Like the Impact Factor, the Eigenfactor Score is essentially a ratio of number of citations to total number of articles. However, unlike the Impact Factor, the Eigenfactor Score:

  • Counts citations to journals in both the sciences and social sciences
  • Eliminates self-citations. Every reference from one article in a journal to another article from the same journal is discounted
  • Weights each reference according to a stochastic measure of the amount of time researchers spend reading the journal

Eigenfactor scores are scaled so that the sum of the Eigenfactor scores of all journals listed in Thomson's Journal Citation Reports (JCR) is 100. In 2006, the journal Nature has the highest Eigenfactor score, with a score of 1.992. The top thousand journals, as ranked by Eigenfactor score, all haveEigenfactor scores above 0.01.

The Eigenfactor uses Thomson Reuters (ISI Web of Knowledge) citation data.

Eigenfactor Motion Charts

Motion charts graphically represent the numerical data from Eigenfactor metrics and Thomsom Reuters WoS.

Motion charts can be adjusted by article influence, Eigenfactor, total articles, total citations, and others. They can be changed into line charts or graphs.
