Which metric should I use for my discipline?

Uses

This section presents the tools that are available to measure the quantitative and qualitative impact of researchers and research. 

Researcher and research metrics can be used to support: 

  • applications for grant funding
  • applications for promotion
  • your research profile

Author Metrics

  • show evidence of high quality refereed publications, creative works or other scholarly activities
  • demonstrate national and international recognition in discipline
  • demonstrate esteem by national or international peers

H-index 

  • The h-index is a metric that attempts to qualify the impact and the quantity of a researcher's publication output
  • The h-index favours established researchers as it increases over time
  • The index h, defined as the number of papers with citation number higher or equal to h, as a useful index to characterize the scientific output of a researcher (J. E. Hirsch. (2005). An index to quantify an individual's scientific research output. Proceedings of the National Academy of Sciences of the United States of America, 102(46), 16569)

                               

Find your H-index

Scopus can be used to obtain a range of metrics relating to an author and their work. To generate an author profile which includes h-index:

1. access Scopus and click the Author Search tab

2. enter Author's surname and initial or first name and click Search Scopus

3. at the Author search results page, click on the name of the author to review their details

This page contains profile information about the author and their publications that are indexed in Scopus. It also contains a full publication list. This information is customisable and a report can be exported.

Web of Science can calculate a range of author metrics, including h-index. To carry out an author search:

  1. select Author Search from the drop-down menu above the search box

  2. type surname and first initial/s (use Author Finder to help you to find variants of the same author name or to distinguish one author from another by field of research and/or address)

  3. click Search, manually select your publications 4. click Create Citation Report (on the right of the page). This includes graphs showing citation patterns and a calculation of the author's h-index. This report is customizable and can be exported

OR

  1. click on +more

  2. enter Author Name, Select Research Domain/s, Select Organization 

  3. review Article Groups and review list of publications, click on Create Citation Report

Google Scholar allows you to set up a profile which contains your publications and citations counts. The profile also provides you with various author metrics, such as h-index. In order to set up your profile, you need to have a Google account

Article Metrics

  • discover who is citing your research
  • find other articles that are highly cited in your discipline
  • demonstrate evidence of sustained growth in citations
  • demonstrate evidence of high quality refereed publications, creative works or other scholarly activities

Citations are a established measure of research impact, however, analysis offered by different tools will have varying results.

When reviewing citation counts consider: 

  • databases collect data from different sources and calculate their metrics differently
  • a journal you published in might not be indexed by the main citation analysis tools: Web of Science, Scopus or Google Scholar
  • recent research articles may not yet have been cited
  • not all contributions to journals are citable e.g. letters to the editor
  • formats such as books and web sites may not be counted
  • publication dates may affect counts
  • frequency of a journal may affect counts
  • highly cited articles don't always mean excellent research, esteem must also be taken in to account
  • research measures across disciplines may differ

Using main citation count databases

Scopus also calculates the number of citations to a document from other documents within Scopus. This is shown in the right-hand column of the search results screen.

Field-Weighted Citation Metric 

Field-Weighted Citation impact takes into account the differences in research behavior across disciplines.

This metric is sourced from SciVal and indicates how the number of citations received by a researcher's publications compares with the average number of citations received by all other similar publications indexed in the Scopus database.

  • A Field-Weighted Citation Impact of 1.00 indicates that the publications have been cited at world average for similar publications.
  • A Field-Weighted Citation Impact of greater than 1.00 indicates that the publications have been cited more than would be expected based on the world average for similar publications, for example a score of 1.44 means that the outputs have been cited 44% more times than expected.
  • A Field-Weighted Citation Impact of less than 1.00 indicates that the publications have been cited less that would be expected based on the world average for similar publications, for example a score of 0.85 means 15% less cited than world average.

Similar publications are those publications in the Scopus database that have the same publication year, publication type and discipline.

Field-Weighted Citation Impact refers to citations received in the year of publication plus the following 3 years.

Field-Weighted Citation Impact metrics are useful to benchmark regardless of differences in size, disciplinary profile, age and publication type composition, and provide and useful way to evaluate the prestige of a researcher’s citation performance.

A Cited Reference search in Web of Science will display the number of articles which have cited a particular article.

To carry out a Cited Reference search:

  • select Cited Reference Search from the drop-down menu above the search box

  • enter the details of the article you wish to find citations for and click Search

  • the article details will be listed, including a 'Citing Articles' column

  • click View Record to access the article record in Web of Science

 

Journal Citation Reports aggregates the meaningful connections of citations created by the research community through the delivery of a rich array of publisher-independent data, metrics and analysis of the world’s most impactful journals included in the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI), part of the Web of Science Core Collection.
