The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly average number of citations of articles published in the last two years in a given journal.

Eigenfactor vs. impact factor-the two widely used measures of a journal’s value. Which metric does one use? It is important for researchers to understand the pros and cons of both metrics.

Evaluates both qualitatively (impact factor or citations) and quantitatively (number of articles) and does not have the disadvantages of other ranking indices such as counting the total number of articles or the total number of citations. 2010 impact factor = A/B; The h index Expresses the journal's number of articles (h) that have received at least h citations. It quantifies both journal scientific productivity and scientific impact and it is also applicable to scientists, countries, etc. Author’s total article count = 33; 18 of the articles are cited at least 18 times; h-index = 18 In terms of the first, we used the recently introduced h-index (Hirsch, 2005) and g-index (Egghe, 2006) to measure journal impact rather than the ISI Journal Impact Factor (JIF). In terms of the second, we used Google Scholar instead of the ISI Web of Knowledge as our data source.

The h-index is defined as the maximum value of h such that the given journal/author has published h papers that have each been cited at least h number of times. In case you are unfamiliar with these measures, impact factor is basically the mean number of citations to articles that were published in the past 2 years; H-index is the largest number h such that h articles have at least h citations each. 2020-12-14 · Impact Factor. SJR. Definition. Citations to a journal in the JCR year to items published in the previous two years, divided by the total number of citable items (articles and reviews) published in the journal in the previous two years. A good H-index score depends not only on a prolific output but also on a large number of citations by other authors. It is important, therefore, that your research reaches a wide audience, preferably one to whom your topic is particularly interesting or relevant, in a clear, high-quality text.

For example, the publication above has the h-core with three articles, those cited by 17, 9, and 6. The h-median of a publication is the median of the citation counts in its h-core.

15 Nov 2005 Instead, the proposed h index measures the broad impact of an Schematic curve of number of citations versus paper number, with papers count as they are superseded by other papers that are being cited at a higher ra

H-index. The h-index is an author-level metric that was invented in 2005 by Jorge Eduardo Hirsch, an Argentine-American professor of physics at the University of California, San Diego. Hirsch is an index that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar by number.

I propose the index h, defined as the number of papers with citation number equal to or greater than h, as a useful index to characterise the scientific output of a researcher (Hirsch, 2005) Impact Factor Bulletin of Marine Science Phytochemistry Citations versus Impact Factor of all papers (2002-2004) Note that the papers with the greatest number of citations are not amongst those published in the journals with the highest Impact Factors. (Nb.

Citation counts are interpreted as measures of the impact or influence of academic work and have given rise to the field of bibliometrics or scientometrics, specializing in the study of patterns of academic impact through citation analysis. A few notable modifications are the m- and g- and e-indices. The m-index, introduced by the creator of the h-index, is defined as the h-index divided by the number of years since the researcher’s first publication. The index is meant to normalize the h-index so that early- and late-stage scientists can be compared.

(impact factor, total number of documents, total number of citations, citation per paper rate and number of highly cited papers).

Therefore, the two cannot be compared. Let me explain. The impact factor is commonly used when measuring journal prestige, whereas the h index is used when measuring researcher impact. It is very hard to compare the two phenomena when making decisions Then the Impact factor of the Journal should be (1298/541)= 2.40 IF. How H-Index is calculated?

Then the Impact factor of the Journal should be (1298/541)= 2.40 IF. How H-Index is calculated? The h-index is a factor determining both the quantity and quality of a scientist’s research output. The h- index is based on a list of publications ranked in descending order …

The h-index The h-index is short for the Hirsch index, which was introduced by Jorge E. Hirsch (2005 ) as a way to quantify the productivity and impact of an individual author. Similar to how the IF is now be used to measure a journal or an author to their scientific field, the h-index has become another measure of relative impact of scientific publications. (impact factor, total number of documents, total number of citations, citation per paper rate and number of highly cited papers). • The h-index can be easily obtained by anyone with access to the Thomson ISI Web of Science and in addition it is easy to understand. However, several limitations of the h-index have also been remarked: Journal impact index: The same as the impact factor, except that it also takes into account journals not included in the Web of Science.
