An Eigenfactor score is a measurement of a journal's impact or importance, using a ratio of the number of articles published to the number of times those articles are cited within the Journal Citation Reports. You can look up an individual journal title or compare the journals of a specific discipline at http://www.eigenfactor.org/projects/journalRank/journalsearch.php.
The Eigenfactor is scaled so that the sum of all the measured journals is 100. A higher score indicates a higher level of importance to the field.
The Eigenfactor site also provides an Article Influence score. This is calculated by dividing the Eigenfactor by the number of articles published in the journal. An Article Influence score greater than 1.00 indicates that the articles in that journal have an above-average influence.
The final column shown in the above image is the Normalized Eigenfactor score. This score is rescaled so that the average journal has a score of 1, making it easier to interpret and compare scores for different journals.
You can find additional information on how the Eigenfactor and Article Influence scores are calculated here: http://www.eigenfactor.org/about.php.
