Raising your research profile
Evidence of exposure: measuring your research IMPACT
Research Support Team
By the end of the session you will be able to:
• Understand the role of research impact metrics
• Identify and apply relevant metrics to your research
• Create alerts to monitor the continued impact of your research
• Understand the potential of social media (and alternative metrics) to increase research impact

Research impact metrics (Bibliometrics) what are they?• A quantifiable way of measuring research output (beyond the
traditional peer-review process)
• They can be used to measure the impact of many aspects of research (research groups, universities, journals and individuals)
• Found in a variety of places: Scopus, Web of Science, Google Scholar etc.
• Traditionally impact measured by the ‘quality’ of where you publish – now there is marked move towards article levels metrics (ALMs)
• Based on citations of your papers
• h-index most commonly used for measuring individuals.
14 April 2023 3
Where to find citation information about your papers• Google Scholar
• Web Of Science
• Scopus
14 April 2023 4
Get notified when you get cited: setting up alerts • Google Scholar
– Setting up Google Scholar profile will enable you to track when your work is cited http://scholar.google.co.uk/intl/en/scholar/citations.html
14 April 2023 5
Scopus alerts
• Register for a personal account for Scopus / go to your author page / select either Follow this Author or Get citation alerts
• You can also create citation alerts for your individual papers
14 April 2023 6
Web of Science alerts
• Register for a personal account / perform an author search / go to search history and save search – you then get the option to set up alert
• Citation alerts for individual papers

What is the h-index?
• Developed by Professor Jorge E. Hirsch
• h short for highly cited or Hirsch
• Measures the impact and quantity of an individual’s research performance i.e. their body of work (unaffected by other factors).
• Enables easier evaluation of authors within specific subject area
• Can helps publishers find new reviewers
• Can help predict future success (Hirsch 2007) - could help with funding applications /employment.
• Recognised way of showing impact.
14 April 2023 8h-index
How it works
• Based on a formula
A scientist has index h if h of his numbers of papers (NP) have at least h citations each and his other papers (NP-h) have fewer then h citations each.
14 April 2023 9
Where to find your h-index
Web of Science (via a Citation report)
14 April 202310
Which h-index to use?
• Variants are due to different source data. – WOS includes references of an author regardless of whether cited items are
indexed by WOS or not.
– Scopus only provides citation data for items indexed by it.
– Google Scholar indexes free abstract data, from open access sources such as institutional repositories, personal websites. Supports disciplines are supported better than others (Computing, Mathematics etc.) due to limited content in traditional databases.
• The one that gives you the HIGHEST score!
14 April 2023 13
Things to note
• h values will vary between subject disciplines (so this must be considered when comparing authors).
• No accounting for age – a more seasoned researcher could potentially have higher h-index as he has had a longer to publish and be cited.
• Check for currency – a researcher may have a high h-index but may not have published for some time and conversely an active (new) researcher may have a low h-index (but of course may has the potential to be cited in the future.)
• h-index is only applicable to traditional research outputs (articles, conference proceedings)
• It can’t capture influence on public policy, improved global health etc.
14 April 2023 14
Alternative metrics (or Altmetrics): what are they?• They “expand our view of what impact looks like, but also of what’s
making the impact.” (Altmetrics manifesto, 2011 http://altmetrics.org/manifesto/)
• New(ish) way of measuring scholarly impact beyond traditional citation counting in the online environment.
• They can reflect the broader social impact of research (a different view of the influence of your work)
• They capture social media references to scholarly output and can reflect public/social engagement
• They are more timely than traditional metrics – can quickly see impact quickly (citation data takes time to accrue).
• Also include PDF downloads and information about abstract/article views.
14 April 2023 15
Examples of Altmetric tools
• Impact Story creates a metrics report for your articles, data sets, slides, software, or webpages.
• Altmetric Labels articles with an altmetrics score, which is a volume, 16
AltmetricLabels articles with a quantitative measure of the quality and quantity of attention that a scholarly article has received.
14 April 2023 17
PLoS article level metricsAvailable for all articles published by PLOS.

Altmetrics and you
• They can offer a more nuanced insight into impact – enabling you to see if your article is being read and discussed.
• Can demonstrate the influence of your research on a more diverse audience (not just academics) practitioners, educators, general public etc.
• Public engagement can help engaging with funding, securing employment/promotion and being accountable.
• They can complement traditional citation metrics.
• For early career researchers (or those changing direction) you can showcase impact earlier.
