Journal Metrics

  1. Overview

    There are many different journal evaluation metrics produced by several companies, each using different sets of data and time periods for their calculations. Most metrics, and all the metrics discussed below, focus on value for scientific and academic research (citations) and do not take into account other ways content is used (e.g. industrial and commercial applications). The below guide is meant to help authors and readers better understand some of the common metrics used to evaluate journal content.

  2. Clarivate Analytics's Journal Citation Reports (JCR) Metrics:

    Date range: varies

    Data source: journals indexed in Clarivate Analytics's Web of Science.

    1. Impact Factor: A metric meant to indicate the number of times the "average" article in the journal is cited. This number is the most widely used metric to evaluate a journal's content. The metric is based on citations in a particular year to articles published over the previous two years. An example of how an Impact Factor is calculated is below.

    2. Total Citations: This is the number of total citations in a given year to all content ever published in a specific journal.
    3. Immediacy Index: a measure of how quickly the "average article" in a journal is cited. The Immediacy index will tell you how often articles published in a given year are cited within the same year.
    4. Cited Half-life: This figure is the median age of the articles cited in the given year. For example, in JCR 2012, Optics Letters has a cited half-life of 6.5 years. That means that articles published in Optics Letters between July 2006 and December 2012 account for 50% of all citations to Optics Letters articles in 2012.
    5. Eigenfactor Score: a metric based on the number of times articles from the journal published in the past five years have been cited in the current year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals. References from one article in a journal to another article from the same journal are removed, so that Eigenfactor Scores are not influenced by journal self-citation.
    6. Article Influence: determines the average influence of a journal's articles over the first five years after publication. It is calculated by dividing a journal's Eigenfactor Score by the number of articles in the journal, normalized as a fraction of all articles in all publications. The mean Article Influence Score is 1.00. A score greater than 1.00 indicates that each article in the journal has above-average influence. A score less than 1.00 indicates that each article in the journal has below-average influence.

  3. Google Scholar Metrics:

    Date range: articles published between 2011 and 2015 and citations as of July 2016.

    Data source: all articles indexed in Google Scholar.

    1. h-index: The h-index of a publication is the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3.
    2. h-core: The h-core of a publication is a set of top cited h articles from the publication. These are the articles that the h-index is based on. For example, the publication above has the h-core with three articles, those cited by 17, 9, and 6.
    3. h-median: The h-median of a publication is the median of the citation counts in its h-core. For example, the h-median of the publication above is 9. The h-median is a measure of the distribution of citations to the articles in the h-core.
    4. Finally, the h5-index, h5-core, and h5-median of a publication are, respectively, the h-index, h-core, and h-median of only those of its articles that were published in the last five complete calendar years.
