Indicators and h-index

Last changed: 31 March 2022

There are many types of bibliometric indicators that measures scientific productivity, citation impact, outreach and visibility. H-index has become increasingly popular as an easy and concise way to measure publication activity, but what does it mean?

Basic bibliometric indicators

  • number of publications and citations
  • number of publications and citations per researcher
  • number of citations per publication
  • number of self citations
  • number of uncited articles
  • h-index
  • Impact Factor 

Basic indicators can not be used for comparisons between different subject areas.

Advanced bibliometric indicators

These indicators are always normalized, the publications are compared with other publications with similar prerequisites, for example the same area of research, the same year of publication, the same document type.

Some examples:

  • field normalized citation score - eg. CPP/FCSm and MNCS 
  • field normalized top publications, Top 5%, indicates the section of publications from a research team that belongs to the 5% most cited in the world.

Field normalized indicators can be used for comparisons between subject areas.

Structural indicators

Publication patterns - sometimes displayed as maps of co-publication and -citation between researchers, co-publication between subject areas, co-publication with other organizations and other countries.

What is h-index?

h-index is a measure that takes both productivity and impact as indicated by number of citations into consideration. It can be calculated for a collection of publications, for example one researcher's production, the whole content of a journal or all publications from a research team. Index h is defined as the number of publications that have been cited h or more times.

How to calculate h-index

When you present indicate an h-index, it is important to specify the database used, and note at what point the h-index has been calculated. The following three databases have different coverage in terms of publications, and therefore can not get the exact same h-index .

Find and mark the publications that should be included in the analysis for the database you have chosen to work with.

  • Web of Science: Click "Create Citation Report" in the upper right corner of the list of search results. This will take you to a new page containing citation statistics for all publications in your list, including h-index for the list.
  • Scopus: In Scopus, click "View Citation Overview" in the upper left corner of your selected list.
  • Google Scholar: Create an account in Google Scholar Citations to be able to select which publications should be included and to view the resulting h-index.

h-index for comparisons

From diverse citing cultures in different research areas follows that h-index will come out differently. H-indexes for researchers in physics are generally much higher than for researchers in social sciences for example. As h-index is based on total production of publications, it will grow with time; the longer a researcher has been active, the higher her or his h-index will become. If h-index is to be used for comparison, it is necessary to take the time dimension into account, and also to compare only with other researchers in the same area of research.

Indicators on journal level

The Journal Impact Factor from Clarivate Analytics is much used, but there are other relevant journal ranking systems, as well as an increasing number of more or less deliberate falsifications.

What is an h-index? How do I find the h-index for a particular author?

Answered By: Laurissa Gann
Last Updated: Dec 22, 2021     Views: 274943

The h-index is a number intended to represent both the productivity and the impact of a particular scientist or scholar, or a group of scientists or scholars (such as a departmental or research group). 

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.  If the scientist's 18th most cited publication was cited only 10 times, the h-index would remain at 17.  If the scientist's 18th most cited publication was cited 18 or more times, the h-index would rise to 18.

Part of the purpose of the h-index is to eliminate outlier publications that might give a skewed picture of a scientist's impact.  For instance, if a scientist published one paper many years ago that was cited 9,374 times, but has since only published papers that have been cited 2 or 3 times each, a straight citation count for that scientist could make it seem that his or her long-term career work was very significant.  The h-index, however, would be much lower, signifying that the scientist's overall body of work was not necessarily as significant.

The following resources will calculate an h-index:

Scopus

Web of Science

Pure (MD Anderson Faculty and Fellows listed)

Keep in mind that different databases will give different values for the h-index.  This is because each database must calculate the value based on the citations it contains.  Since databases cover different publications in different ranges of years, the h-index result will therefore vary.   You should also keep in mind that what is considered a "good" h-index may differ depending on the scientific discipline.  A number that is considered low in one field might be considered quite high in another field.

Research Impact: Citation Indexes

A guide to measuring impact for authors of scholarly publications.

Citation Indexes Overview

What are index numbers?

Citation index numbers provide a way to measure impact beyond raw citation counts. Index numbers can be calculated for individual articles, a group/list of publications, or even all the articles published in a journal or field (see our Journal Impact page).

What is the "best" index number?

Generally, the "best" measurement depends on what matters to you. The h-index is the most widely known index measurement. Some alternative measurements, like the g-index, address specific issues with the h-index. Other measurements target recent publications and citations, such as the the contemporary h-index. 

Other Citation Index Numbers

Alternatives to the h-index include:

  • g-indexGives more weight to highly cited publications. The original h-index is insensitive to high "outliers" -- a few papers that have very high citation counts will not sway the h-index score (much). The g-index allows highly cited papers to play a larger role in the index, and tends to emphasize visibility and "lifetime achievement."
  • hc-index (contemporary h-index): Gives more weight to recent publications. The original h-index favors senior researchers with extensive publication records, even if they have ceased publishing. The hc-index attempts to correct this and favors researchers currently publishing.
  • i10-index: Measures the number of papers that have at least 10 citations. Introduced (and used) by Google Scholar.
  • m-quotient: Divides the h-index by the number of years since the researcher's first published paper. m-quotient was proposed as a way to help younger researchers who may not have long publication lists.

For more index measurements, we suggest "Reflections on the h-index," by Prof. Anne-Wil Harzing, University of Melbourne.

h-index

What is the h-index?

The h-index attempts to correlate a researcher's total publications and total citations. It was proposed by Jorge E. Hirsch in 2005 ("An index to quantify an individual's scientific research output," PNAS November 15, 2005 vol. 102 no. 46 16569-16572). For more information, see the Wikipedia article.

chart showing H-index for citation counts; the number of papers are displayed along the x-axis and the citation count is measured along the y-axis

Graph of the h-index, from Wikipedia.

How do I calculate my h-index?

  • Web of Science or Google Scholar will automatically calculate the h-index for the list of publications in your profile. 
  • Publish or Perish will calculate h-index (and many other index numbers) for an author's publications. 
  • If you want to calculate an h-index manually, Hirsch defines the h-index as follows: "A scientist has index h if h of his or her Np papers have at least h citations each and the other (Np – h) papers have ≤h citations each."

Increasing the Visibility and Impact of Your Research

Scholarly Impact Metrics

Scholarly impact metrics provide evidence of impact for scholarly work. While impact metrics are not without critics, familiarizing yourself with them can provide you with some information regarding the extent to which your work is making an impact in your field or beyond. By examining the data that these metrics provide, you can evaluate whether you current publishing strategy is effective or whether you should consider alternative venues for disseminating your work. 

Impact metrics can also be beneficial when it comes time to write a scholarly impact narrative for tenure, promotion, or other evaluative processes. By referencing specific metrics, you can justify your narrative by providing both qualitative and quantitative indicators of impact. 

Types of Metrics

Scholarly impact metrics can be used to evaluate impact at three different levels.

  • Article-level metrics indicate the impact of a single publication, such as a journal article. They include number of times the article was cited as well as download and other usage statistics.
  • Author-level metrics indicate the impact of an individual author throughout their career. The h-index is one of the most well-known author-level metrics.
  • Journal-level metrics indicate the impact of a journal as a whole. The Journal Impact Factor is the most well-known journal-level metric.

In addition to these three levels, we can also differentiate between traditional metrics and altmetrics (i.e. alternative metrics). Traditional metrics include citation counts, the h-index, and journal impact factor. While traditional metrics are typically used to measure the impact of research within the scholarly community, altmetrics provide insight into a work's societal impact. They often reflect online discussions of research, such as Wikipedia citations, social media mentions, media coverage, or references in public policy documents.

Bibliometrics & Citation Analysis

How can you measure the quality of a research paper? More importantly, how can you determine whether your research is making an impact and is considered important? An objective way is through citation analysis.

Citation analyses can be grouped according to some broad types based on who/what is being evaluated (Source).

  • Ranking Journals
  • Ranking Researchers
  • Ranking Articles
  • Ranking Universities & Countries

Terms & Definitions

Altmetrics

In scholarly and scientific publishing, altmetrics are non-traditional metrics proposed as an alternative to more traditional citation impact metrics, such as impact factor and h-index. The term altmetrics was proposed in 2010, as a generalization of article level metrics, and has its roots in the #altmetrics hashtag. (Source)

Bibliometrics

Bibliometrics is statistical analysis of written publications, such as books or articles. Bibliometric methods are frequently used in the field of library and information science, including scientometrics. For instance, bibliometrics are used to provide quantitative analysis of academic literature. (Source)

Citation analysis

Citation analysis is the examination of the frequency, patterns, and graphs of citations in articles and books.It uses citations in scholarly works to establish links to other works or other researchers.Citation analysis is one of the most widely used methods of bibliometrics.

Citation impact

Citation impact quantifies the citation usage of scholarly works. It is a result of citation analysis or bibliometrics. Among the measures that have emerged from citation analysis are the citation counts for are those for an individual article, an author, and an academic journal. (Source

Citation impact: Article level

One of the most basic citation metrics is how often an article was cited in other articles, books, or other sources (such as theses). Citation rates are heavily dependent on the discipline and the number of people working in that area (Source)

Citation impact: Journal ranking

Journal ranking is widely used in academic circles in the evaluation of an academic journal's impact and quality. Journal rankings are intended to reflect the place of a journal within its field, the relative difficulty of being published in that journal, and the prestige associated with it. (Source). The basic journal metric is the average citation count for the articles in a journal; other metrics include (Source):

  • Impact factor – Reflecting the average number of citations to articles published in science and social science journals.
  • h-index – Usually used as a measure of scientific productivity and the scientific impact of an individual scientist, but can also be used to rank journals. 
  • SCImago Journal Rank – A measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from.

Research Output

Research output is defined as textual output where research is understood as original, systematic investigation undertaken in order to gain new knowledge and understanding. Peer evaluation of the research is a fundamental prerequisite of all recognised output and is the mechanism of ensuring and thus enhancing quality. (Policy on Research Output)

Using citation analysis to measure research impact


The landscape of science and research is rapidly evolving. Gone are the days when all members of a university department would celebrate the successful publication of a colleague’s paper.1 Earlier, scientists would simply consider the number of papers they had published as a measure of their academic standing. Today, the focus is increasingly shifting from whether a researcher has published a paper to where he/she has published it and the impact that piece of research has on the scientific community and the world at large.2

How can you measure the quality of a research paper? More importantly, how can you determine whether your research is making an impact and is considered important? An objective way is through citation analysis.

Citation analysis

Why count citations in the first place? The list of references directing readers to prior relevant research is considered a fundamental part of any research paper.3 A reference or citation is a form of acknowledgment that one research paper gives to another. Research is additive—scientists build on past work to discover new knowledge. To identify gaps in existing research and choose a research topic, researchers read the relevant published research and use this existing material as a foundation for arguments made in their own research papers.

11 reasons to cite previous work

  1. To direct readers to an authentic source of relevant information
  2. To help other researchers trace the genealogy of your ideas
  3. To acknowledge pioneers and peers
  4. To direct readers to previously used methods, and equipment
  5. To criticize or correct previous work
  6. To substantiate your claims and arguments with evidence
  7. To show that you have considered various opinions in framing your arguments
  8. To highlight the originality of your work in the context of previous work
  9. To guide other researchers in their work
  10. To build your credibility as an author
  11. Finally, because not citing sources can amount to plagiarism4

What are the various citation-based metrics?

Citation analyses can be grouped according to some broad types based on who/what is being evaluated.

  1. Ranking journals: Journals are ranked by counting the number of times their papers are cited in other journals. Journal-level metrics are generally meant to serve as an indicator of journal prestige. The most well known of these is the journal impact factor, from Journal Citation Reports®(a product of Thomson Reuters). The journal impact factor is calculated as the average number of citations all articles in a journal receive over a specific period of time.5
  2. Ranking researchers: Various citation metrics are now used for this purpose. Researchers are ranked by counting the number of times their individual papers are cited in other published studies. These metrics are also used to evaluate researchers for hiring, tenure, and grant decisions. A researcher-level metric that is gaining popularity is the h index,6 which is calculated by considering a combination of the number of papers published by a researcher and the number of citations these papers have received.
  3. Ranking articles: Article-level citation counts may provide an accurate evaluation of the quality and impact of a specific piece of work, regardless of the author. Unfortunately though, such metrics are rarely considered because obtaining these data is tedious and time-consuming.7
  4. Ranking universities and countries: There are databases that rank universities and countries by considering their overall research output through criteria such as citable documents, citations per document, and total citations. These metrics help determine which universities and countries have the most and/or best scientific output. For example, Scimago Research Group (http://www.scimago.es/ ) releases annual reports of institution- and country-wise rankings.

How can citation analysis help you?

Researchers today are faced with increasing pressure to get published. Academic departments are expected to meet specific levels of publication output. Clearly, there is a lot at stake in the assessment of research quality for both individuals and institutions. Given this, governments, funding agencies, and tenure and promotion committees are looking toward simple and objective methods to assess increasing research volumes in the least possible time. To this end, they are turning more and more to citation analysis for objective parameters of impact assessment.

Pitfalls of citation analysis

When using citation analysis, it is important to bear in mind some of its limitations3,7:

  • It overlooks the disparity in discipline-wise citation rates, that is, the fact that citation patterns differ among disciplines and over time.
  • It ignores the fact that certain manuscript types such as letters and case reports offer inadequate scope for citation and typically have short reference lists. The sentiment of the citation is not considered; that is a negative citation (one used to refute a prior claim) is given as much merit as a positive citation (one used to further the claim being made). So even a paper that has been cited simply to discredit it can work to the author’s advantage in citation analysis.
  • It does not account for author contribution on papers with multiple authors: such citations are as meritorious as those to single-author papers. Citation analysis attributes equal importance to all authors of a paper, regardless of their individual contribution.

Thus, sole reliance on citation data provides an incomplete understanding of research. Although citation analysis may be simple to apply, it should be used with caution to avoid it coming under disrepute through uncritical use.3 Ideally, citation analysis should be performed to supplement, not replace, a robust system of expert review to determine the actual quality and impact of published research.8

Future of citation analysis

Given the shift to online interfaces by more and more journals and repositories, digital information is now available at a few clicks. With the advent of linking tools and digital archives of research papers, scientific literature is more easily retrievable than ever before. Therefore, it is only to be expected that the population of researchers turning to citation data will continue to grow. In such a scenario, researchers cannot afford to undermine the importance of citation analysis.

So next time you are preparing for a promotion or applying for a new position, consider using citation analysis as a means to bolster your eligibility. Use the citation count feature offered by online databases like Web of Science to compile your citation data and employ multiple citation metrics to highlight your research output.

Ranking Researchers

Various citation metrics are now used for this purpose. Researchers are ranked by counting the number of times their individual papers are cited in other published studies. These metrics are also used to evaluate researchers for hiring, tenure, and grant decisions. A researcher-level metric that is gaining popularity is the h index, which is calculated by considering a combination of the number of papers published by a researcher and the number of citations these papers have received. (Source

The following resources can help researchers manage their career through citation counts and the h-index.  

 

Scopus is a subscription database known primarily as an alternative to Web of Knowledge, as it offers a similar article, author, and journal-level metrics, but uses slightly different algorithms to calculate them. Metrics include standard options such as times cited and h-index, as well as original offerings like SJR and SNIP from SCImago. Scopus recently launched “Altmetric for Scopus,” a third party application that runs within the sidebar of Scopus pages to track mentions of papers across social media sites, science blogs, media outlets, and reference managers.

This Thomson Reuters subscription database helped usher in modern bibliometrics with its introduction of the h-index in 1982. Web of Knowledge includes Web of Science, for article and author queries, and Journal Citation Reports, for finding accredited and impact journals. Its metrics include times cited, h-index, impact factor, Eigenfactor, and field-based journal rankings. While many of these metrics have been criticized for not fully representing scholarly value in certain disciplines, they are still considered the gold standard in traditional bibliometrics.


  

Google Scholar Citations provide a simple way for authors to keep track of citations to their articles. You can check who is citing your publications, graph citations over time, and compute several citation metrics. You can also make your profile public, so that it may appear in Google Scholar results when people search for your name. Best of all, it's quick to set up and simple to maintain - even if you have written hundreds of articles, and even if your name is shared by several different scholars. You can add groups of related articles, not just one article at a time; and your citation metrics are computed and updated automatically as Google Scholar finds new citations to your work on the web. You can choose to have your list of articles updated automatically or review the updates yourself, or to manually update your articles at any time

What is the Journal impact Factor?

Journals are ranked by counting the number of times their papers are cited in other journals. Journal-level metrics are generally meant to serve as an indicator of journal prestige. The most well known of these is the journal impact factor, from Journal Citation Reports® (a product of Thomson Reuters). (Source

The journal impact factor (IF) is a measure reflecting the average number of citations to recent articles published in the journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones (Wikipedia)

Journal Metrics by Elsevier

Elsevier now provides three alternative, transparent and accurate views of the true citation impact a journal makes:

SCImago Journal Rank (SJR) is a prestige metric based on the idea that 'all citations are not created equal'. With SJR, the subject field, quality and reputation of the journal have a direct effect on the value of a citation. SJR is a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from. It is a variant of the eigenvector centrality measure used in network theory.

The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus database. These indicators can be used to assess and analyze scientific domains.

This platform takes its name from the SCImago Journal Rank (SJR) indicatorp, developed by SCImago from the widely known algorithm Google PageRank. This indicator shows the visibility of the journals contained in the Scopus® database from 1996.
