This document discusses research metrics and how they are used to measure the impact and influence of scientific research. It defines several types of metrics including journal impact factors, author metrics, article metrics, and altmetrics. It also explains how impact factors are calculated for journals and describes other measures like the h-index, SNIP, and IPP that provide additional ways to evaluate research outputs and impacts. Scopus and the Web of Science are identified as databases used to find citation counts and metrics.

2. Research Metrics
Research Metrics is the quantitative analysis of scientific
and scholarly research outputs and their impacts.
 Research Metrics include a variety of measures and
statistical methods for assessing the quality and broader
impact of scientific and scholarly research, as well as to track
researcher impact
 Research Metrics measure impact and provide insight into
the influence of specific journal publications, individual
articles, and authors.

3. Research Metrics Measures
Journal Metrics, such as Impact Factor, helps track citation patterns
within journals and determine which journals are highly-cited.
Author Metrics measure the impact and productivity of a
researcher.
Article Metrics, or citation tracking, is used to determine if an
article, book, journal, or particular author has been cited by another
work.
Altmetrics help researchers measure their impact from papers, data
sets, websites, blog posts, and more. A collated record of all the on
line shares and views of your research

7. • A journal impact factor (JIF) is a measure of
how many citations an average article
receives over a given period.
• Bibliometrics is the use of statistical methods
to analyze books, articles and other
publications.
• The sub-field of bibliometrics which concerns
itself with the analysis of scientific
publications is called scientometrics

8. First mention of Impact Factor
Garfield recommends keeping track of who
cited the paper.
“In effect, the system would provide a complete
listing, for the publications covered, of all the
original articles that had referred to the article in
question.” … Such an “impact factor” may be
much more indicative than an absolute count of a
scientist's publications.”
Here impact factor refers to the impact of the
article.

9. Impact Factors for Journals
In the early 1960’s Irving H. Sher and Eugene
Garfield created the Journal Impact Factor to help
select journals for Science Citation Index (SCI).
They knew that a core group of highly cited large
journals needed to be covered in SCI, but they also
wanted to include the small, but important review
journals which would not be included if they relied
only on publication or citation counts.
Created the Journal Impact Factor

10. Impact Factor
The Impact Factor is calculated by dividing the number of
citations in the Journal Citation Report (JCR) in a
particular year by the total number of articles published in
the two previous years.

Self-citations affect the evaluation of the journal
Most journals have self-citation
rates of less than or equal to 15%
Source: JCR Science Edition (2010)
o Excessive self-citation weakens the integrity of the journal’s Impact
Factor
o Journals with excessive self-citation may be suppressed from Journal
Citation Reports until the problem is corrected
85%

16. SNIP-Source Normalised Impact per Paper
• SNIP=
No.of citations in present year of
publications of last 3 years
Total no.of publications in last 3 years.

18. IMPACT PER PUBLICATION(IPP)
• Calculated as the number of citations given in the
present year of publications in the past 3 years divided
by the total number of publications in the past 3 years.
• IPP does not correct or normalise for differences in
citation practice between scientific field.
IPP=
No.of citations in present year of publications of
last 3 years
Total no.of publications in last 3 years.

19. H INDEX

20. H Index
It is an index that attempts to measure both the
productivity and impact of the published work of
a scientist or scholar.
A scholar with an index of h has published h
papers each of which has been cited by others at
least h times.
Serves as an alternative to more traditional
journal impact factor metrics in the evaluation of
the impact of the work of a particular researcher

21. Author H Index
The h-index “gives an estimate of the importance,
significance, and broad impact of a scientist’s
cumulative research contributions”
Hirsch, J. E. (2005). An index to quantify an
individual's scientific research output.
Proceedings of the National Academy of Sciences,
102(46), 16569-16572

22. Finding H Index in SCOPUS
SCOPUS calculates the h-index of an author or a
group of authors using journal publications from
1996-upto current publication.
ie papers published before 1996 are not included
in the calculation. Publications such as book
chapters are not included in the list of
publications or as sources for the citation count.

Investigaciones Científicas (CSIC), University of Granada,
Extremadura, Carlos III (Madrid) and Alcalá de Henares,
dedicated to information analysis, representation and retrieval
by means of visualisation techniques.

31. Citation Index
A citation analysis measures the number of
times an author, article, journal or institution
is cited in the academic literature covered, in
this instance, by ISI’s Web of Science.

Scopus helps Researchers
• Find out how many citations an article or an author has received.
• Analyze citations for a particular journal issue, volume or year.
• Use this information to complete grant or other applications quickly
and easily.
• Use the refine results overview to quickly see the main journals,
disciplines and authors that publish in one’s area of interest.
• Uncover important and relevant articles that one may otherwise
miss.
• Check out the work and citations of other authors.
• Click on the cited by and reference links to track research trends
and make connections. One can do this within or across disciplines
one is interested in.
