The journalimpact factor is a measure of the frequency with which the "average article" in a journal has been cited in a particular year. The impact factor will help you evaluate a journal’s relative importance, especially when you compare it to others in the same field.

Measuring impact (for Newcastle University Research Staff)
Your Research Impact:
how to measure the impact of your publications
Am I famous yet?

Making and measuring impact workshops
Things to consider pre-publication
• Create an (academic) online profile
• Understand & use the Journal Citation Report (JCR) and other journal
• Understand Open Access publishing models
• Understand how to apply for OA publishing funds at Newcastle University
Things to consider post publication
• Who has been reading it?
• How often?
• Where from?
• Have I made a difference?
Why do we want to know?
Was anyone interested in my research?
Who, why, what did they do?
Making contacts and connections for future
Feel good factor – exciting, challenging
Making a difference – social responsibility
Building your reputation, recognition

Of a Journal
How much impact does a specific journal have on the
How many times are articles from that journal cited by
Use Impact Factors
Of an article
How often was a specific article cited/read by others?
Of an individual author
What impact is an individual person having on the
How important is an individual?
Use h-index and other metrics
Count web/blog page hits
Journal impact using Impact Factors
Use impact factors to:
Measure the impact of a journal on the community
Identify the relative importance of a journal
Identify key journals to read
Identify places to publish
Measure the quality of research output of an institution
Find Impact Factors using:

Limitations of the JCR
Only covers journals indexed in the Web of Science
Known subject gaps eg engineering
May not cover new or niche subject areas
New / changed titles not covered for 2-3 years

Calculating the h index
A scholar with an index of h has published h papers, each of
which has been cited by others at least h times
Use WoK or Scopus
WoK h=61 Scopus h=48
WoK h=42 Scopus h=33
WoK h=44 Scopus h=42
May vary depending on forms of author name, affiliation
As with any metric, use with caution!

H index issues
Comparing apples and pears
Varies depending on database
Varies depending on discipline
One seminal paper does not imply high h-index
Doesn‟t recognise new researchers
Doesn‟t allow weighting in multi-authored papers
Can be slightly skewed by self citation
May miss out key articles
May not account for books, book chapters, reports and
other types of resource
Google Scholar Citations www.scholar.google.co.uk
Can work out your personal citation data
Widget for other people‟s data – accuracy is debatable
Has h-index for journals as well as individuals
Publish or Perish: (http://www.harzing.com/pop.htm) (free)
Uses Google Scholar citations, and runs as standalone software that links
to the web.
Has to be downloaded
Difficult to identify publications
Less accurate than Scopus or WoS,

g and m index…
The g-index (Leo Egghe)
the g-index is the (unique) largest number such that the top g
articles received (together) at least g2 citations.
It aims to improve on the h-index by giving more weight to
The m-index is defined as h/n, where n is the number of years
since the first published paper of the scientist
Other publication types
Conference papers and reports
may be indexed in databases such as WoK
Individual collections eg ACM digital library may
provide citation info
Books – citation data included in some databases (esp Google
Scholar) but inconsistent.

Altmetrics- alternative metrics
Altmetrics manifesto http://altmetrics.org/manifesto/
“No-one can read everything…”
Traditional filters (citation counts, h-index, JIF…)
Slow, take a long time to accumulate
Don‟t always measure impact at article level
Restricted – behind paywalls
Neglect impact outside of academia
Don‟t take account of scholarly attention received via new channels
The creation and study of new metrics based on the social
web for analysing and informing scholarship
A supplemental measure of the quality of scholarship
Altmetrics data is being collected from many
Views – HTML views and PDF downloads
Mentions – blog posts, Wikipedia articles, online
news items, comments on blog posts, etc
Social Media – Twitter, Facebook, LinkedIn,
Captures/Shares – Mendeley, CiteULike, social
Cites – citations in the scholarly literature, tracked
by Web of Science, PubMed, Scopus, etc
Combination of scholarly attention and
Maximising your altmetrics impact
For example, create a profile on
Or write a blog/ tweet/ join other social research networks
Do altmetrics reflect actual impact or just „buzz‟?
Can altmetrics distinguish „scholarly interest‟ from
Isn‟t „gaming‟ easy?
Tools to enable institutional comparisons much less
developed than tools for individual researcher
Can be difficult to interpret – require scrutiny,
contextualisation and interpretation
