If you decide to submit your manuscript for publication in a research journal, it is important to understand the common journal metrics which help you decide whether the journal is suitable for your publication or not.
Journal metrics are the measurement, and comparison of scientific and scholarly publications, often on any database, and are also referred to as journal impact, journal importance, journal ranking, and journal evaluations which allow scientists and researchers to compare the peer-reviewed scientific journals with other journals, magazines, and more.
Here are some of the most popular metrics used for the calculation of journal metric, and these metric, are usually divided into different categories on the basis of source, like Web of Science, Google Scholar, Scopus, and the Journal Citation Report sources used for the calculation of the journal metric.
The database used to calculate each journal or magazine metrics on the basis of the criteria set and the statements and figures that are used to measure the prestige of a journal within its database.
In general all the reputed journal are analysis on the basis of the following metrics.
Please note: There are no perfect indicators for the evaluation of the journal metric and the pro and cons of each of the metric system of measures is there. However, we must trust some metrics for the selection of a suitable journal for our research paper, which will save our time and effort, and ensures a quality solution.
Top journal metric used for Journal evaluation
The 5-Year Impact Factor metric (Web of science)
The Impact Factor is calculated by collecting the citation score of each article and the number of articles published in the last 5 years.
The 5-year impact factor is the average number of citations on articles published within the last five years, as per the JCR year report and it is calculated by dividing the number of citations in a JCR year by the total number of articles published in the last five years.
Calculation is as follow
The Eigenfactors Metric (Web of science)
In many fields of scientific papers are often not cited, within a few years of their publication and in this, the citation data in the first two years after the date of publication may be misleading. The Eigenfactor score and the impact score of the items have been calculated on the basis of citations received in a period of five years.
Hence the Eigenfactor is based on the weighted citations per JCR year by the articles published within the last 5 years. Citations are weighted by the prestige of the cited journal, and quotes from high-ranking journals, to contribute to their own factor, rather than low-ranked journals.
The Article influence metric (Web of science)
Article influence shall be calculated by dividing the Eigenfactor score, with a percentage of all of the articles and journals are recorded in the citation reports that were published in the pages of this magazine and its rating will be determined by the average of the effect of the item (s) within the first five years of its publication.
It is calculated by multiplying the equity factor is 0.01, and dividing the result by the number of articles in the journal, normalized as a share of all articles in all publications.
The equation is as follows:
Where X = 5-years, the Number of articles in journals and Magazines, divided by a 5-year, the number of articles from all journals.
The Immediacy Index metric (Web of science)
The immediacy index is the average number of citations of a paper in the year of its publication and this index is calculated by dividing the number of citations to articles published in a given year by the total number of articles published this year. Because of this, it is to the average value for each of the articles, the Immediacy Index, and has the tendency to discount the benefits of a large logs across the world.
The journal Immediacy Index is calculated by using following formula:
The journal immediacy index indicate that how quickly an article is cited.
The Impact factor metric (Web of science)
The Impact factor of a journal is calculated by any database by taking the average number of citations on articles published within the last two years and in the JCR year.
The impact factor is calculated by dividing the number of citations per JCR year by the total number of articles published in the previous two years.
For example: If the journal has an impact factor of 10 in 2020, that means all the articles published in 2018 and 2019 have, on average, 10 citations each during that period
For example we calculate the IF of journal X in 2020
In this case we take data only from citable articles published form 2018 to 2019 years
The CiteScore metric (Scopus metric)
CiteScore metric is the part of the Scopus Data, which is the SNIP (Source Normalized Impact on the Stock), SJR (SCImago Journal Rank), and the number of citations and documents, and the percentages are enclosed in quotation marks. With the inclusion of such data in Scopus, you can get information about the impact of citations for more than 22,220 titles.
CiteScore metrics are part of the permanent collection of the research data available on or Scopus database and supports a holistic view of the results of the study.
CiteScore is the number of citations received by the journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in the same three-year period.
The SJR metric (Scopus metric)
The SCImago Journal Rank (SJR) is the average number of weighted citations received in a particular year by the documents published in a particular journal during the previous three years, i.e., weighted citations received in year X to documents published in a journal during the period of the X-1, X-2 and X-3.
Citations can definite as the prestige of the cited journal, and so is a direct citations from a top-ranked journal, you will have a greater impact than just a citations from a low-ranked, and research.
For example, you can see the SJR score of the Journal on SJR journal ranking, with the help of various disciplines, journals, subject categories, and publication in the following regions/countries, in the year of publication
The SNIP metric (Scopus metric)
The source of Normalizing Effect on the Paper (SNIP) measures the average citation at the year X to papers published in the last 3 years. The citation is added into the citation potential of a specific journal category, which is the metric of comparable across the different disciplines.
It does this by comparing each of the journal’s citations by publication and the citation potential of the area, which is defined as a set of publications citing that journal.
So, the SNIP is the quick and easy way to measure the citation impact and allows you to compare journals in a variety of fields, because the cost of a direct citation is greater for journals in the areas where the citation is to reduce the frequency, and vice-versa.
The SNIP will be calculated annually on the basis of Scopus data, and it is freely available, along with a CiteScore and SJR at Scopus Website
The Google Scholar Metric (Google Scholar)
It provides authors an easy way to make a quick review of the visibility and the impact of recent articles in scholarly publications and summarize the recent links to several publications, to help authors as they consider where to publish their new research.
The most important metric for Google Scholar, is the H5-index, which is based on the articles published in the last 5 full calendar years.
It seems to that of h-index, but it also includes the most frequently cited h articles (h-core), and the median number of citations, h-median), and one can check these citations of each article by clicking on the H-index
You can check out the Google metric of journals on the Google scholar baseboard by the selection, category of the journal, subcategories for specific publications in all languages, and their names.
The H-index metric (any sources)
The H-index has been calculated on the basis of data from a variety of sources, such as Web of Science, Google Scholar or Scopus, etc. The h-index attempts to measure the productivity and citation rate of all of an author’s published work.
It indicator that determines the number of articles (h), which has been cited at least h times of the day
For example, h-index is 25, it means 25 articles have been cited at least 25 times each.
Please note: Due to the differences in coverage between citation databases, and for each resource, you can specify a different value of the h-index for each author.
Let’s calculate the h-index of a journal having 10 articles (h) that received at least 8 citations. To measure the performance of a peer-reviewed scientific journals, and scientific impact, as well as links to the scientists, countries, etc.
The journal total article count = 9 and out of which almost first 8 papers (1 to 8) are cited at least 8 times or more
Hence the H-index value is = 8
Last but not least ISI ranking and Altmetrics are also used for the calculation of journal metric.
ISI ranking metric: In this metric, the rating of the journals on the base of impact factor and the rating must be of 2 years old or a 5-year-old impact factor and sourced by a web of science. Do not compare 2 years ranking with the 5 year ranking of a journal. “The position has always been in the context of a particular class.” In this section, you will need to see the logs in the same category and type. Therefore, the logs are ordered within a given category based on theirs.
Altmetrics metric; It is a metric of any of the sources, such as Scopus, Web of Science, PubMed Central, Google Scholar citations; citations in the document.
Altmetrics, it goes beyond the traditional citation metrics for the measurement of social visibility around for a scientific article. This information is based on a wide range of metrics, such as tweets, blog mentions, news, sites, media, social bookmarks, reviews, articles, and downloads.
