Does h-index include self citations?

Self-citations or gratuitous citations among colleagues can skew the h index. The h index will vary among resources depending on the publication data that is included in the calculation of the index. The h index disregards author ranking and co-author characteristics on publications.

Does self citation count?

Self-citation occurs in an article when an author references another of their own publications. This can be a legitimate way to reference earlier findings; but self-citations can sometimes be unduly made in attempt to inflate an individual's citation count.

What is the h-index for citations?

The h-index is calculated by counting the number of publications for which an author has been cited by other authors at least that same number of times. For instance, an h-index of 17 means that the scientist has published at least 17 papers that have each been cited at least 17 times.

Does Google Scholar remove self-citations?

Google Scholar: It is not possible to eliminate self-citations in an author profile directly; however, this feature is available using the free Publish or Perish software.

How many citations for h-index 4?

In this case, they have a h-index score of 4, meaning they have at least 4 papers with 4 citations each. (Image credit: Laura Grassie.) So, if you have an h-index of 20, you have 20 papers with at least 20 citations.

Google Scholar 2018: Important settings to increase author citations

Is 32 a good h-index?

According to Hirsch, a person with 20 years of research experience with an h-index of 20 is considered good, 40 is great, and 60 is remarkable.

What is the average h-index for a full professor?

h-index scores between 3 and 5 feel common for new adjunct professors, scores between 8 and 12 fairly standard for creation to the position of tenured associate professor, and scores between 15 and 20 about right for coming a full professor.

Does h-index exclude self citations?

Interestingly, Hirsch (2005) concluded that "self-citation would not significantly affect the h-index of an individual author. Although self-citations can obviously increase a scientist's h-index, he contended that their effect on the h-index is much smaller than on the total citation count" ( Brown, 2009 ).

Is self-citation good or bad?

[34] , a study for self-citation analysis found that self-citation is considered good practice if it is at an acceptable rate, but if it is at an excessive rate, it will be a bad practice and lead to unfair evaluation.

How many Google Scholar citations is a lot?

Generally speaking, a good number of citations for a paper is considered to be more than 10–20 citations. However, some fields may require more or fewer citations depending on the topic and the journal.

What is a respectable h-index?

H-index scores between 3 and 5 seem common for new assistant professors, scores between 8 and 12 fairly standard for promotion to the position of tenured associate professor, and scores between 15 and 20 about right for becoming a full professor.

What is the difference between citations and h-index?

The h-index is the largest number h such that h articles have at least h citations each. For example, if an author has five publications, with 9, 7, 6, 2, and 1 citations (ordered from greatest to least), then the author's h-index is 3, because the author has three publications with 3 or more citations.

How do you increase h-index and citations?

How much self-citation is acceptable?

Well, as there is no rule on the total number of citations in a full-size paper (depending on the topic, it may vary from a handful to a few hundreds), there is no strict limit as to the ratio of self-citations.

What is the highest h-index score?

Scientists with High H-Indexes

At the time of writing, the highest score recorded by Google Scholar is 300, by researcher Ronald C Kessler from Harvard University. JoAnn E Manson from Brigham and Women's Hospital takes second place with a score of 294.

Is self-citation biased?

This is what we call the self-citation bias: the preference researchers have to refer to their own work when they guide readers to the relevant literature. We argue that this finding is difficult to under- stand within the traditional, science-based view, which says that reference lists are there to help the reader.

Is self-citation unethical?

Researchers may be tempted to include multiple citations to their own work with the aim of increasing the citation numbers of their previously published articles, which in turn affects their h-index. Citation manipulation, which includes excessive self-citation, is a form of research misconduct and must be avoided.

What is the percentage of self-citation?

Of course, in scientometric studies, self-citation by 20 percent is conservatively allowed for researchers as a tolerable limit, while beyond that is considered illogical and inappropriate (1).

What are the different types of self citations?

Two different types of self-citations are described: author self-citations (citations received from the author him/herself) and co-author self-citations (citations received from the researchers' co-authors but without his/her participation).

What is a good h-index after 30 years?

h index of 60 after 20 years, or 90 after 30 years, characterizes truly unique individuals.

What is the problem with h-index?

Because the h-index does not take into account the number of authors in publications, the h-index is computed by ignoring the difference between partial contributions in multiauthored publications and full contributions in single-authored publications, thus creating unfairness in assessing research contributions.

What is a good h-index for a chemistry professor?

We found that, on average, assistant professors have an h-index of 2-5, associate professors 6-10, and full professors 12-24. These are mean or median values only—the distribution of values at each rank is very wide. If you hope to win a Nobel Prize, your h-index should be at least 35 and preferably closer to 70.

How do you calculate h-index in college?

What is the h-index? The h-index is a measure of the number of publications published (productivity), as well as how often they are cited. h-index = the number of publications with a citation number greater than or equal to h. For example, 15 publications cited 15 times or more, is a h-index of 15.

What is the average h-index of Nobel laureates?

The average h-index of price award winners (17.77) was found to be less than that of Nobel prize winners in physics (34.5), chemistry (65.17), and economics (67.31), as reported in previous research (Farhadi et al, 2013).
