IEEE Impact Factor vs Google Scholar h5-index

Data was updated in June 2013 (IEEE) and Sept 2013 (Google Scholar)

Impact Factor: Impact Factor is the average number of times articles from a journal published in the past two years have been cited in the JCR year. The Impact Factor is a so-called popularity measure which relies on the crude number of citations, each of them counting the same independently of the quality of the source.

Eigenfactor™Score takes into account the number of times articles from a journal published in the last five years have been cited in the JCR year while also considering which journals have contributed these citations. Since citations are in this case weighted dependently on the source, The Eigenfactor Score belongs to the class of so-called prestige measures. The Eigenfactor Score represents the probability of reading a specific journal in the entire collection and therefore high-scoring journals have a greater influence in the scientific community.

Article Influence™Score is also a prestige measure and has all the features of the Eigenfactor Score, with an additional normalization to the number of published papers. Hence it can be considered the average influence of a journal's articles over the first five years after publication.

h-index is the largest number h such that h publications have at least h citations. The second column has the "recent" version of this metric which is the largest number h such that h publications have at least h new citations in the last 5 years.

h5-index is the h-index for articles published in the last 5 complete years. It is the largest number h such that h articles published in 2008-2012 have at least h citations each.

h5-median for a publication is the median number of citations for the articles that make up its h5-index.
