10. Citation Tracking /
Searching
Citation tracking allows you to:
Find out how many times a paper
has been cited
Search backwards and forwards
in time to see how ideas develop
Find the most highly cited papers
in your field
Identify key researchers and
institutions by their citation
counts
11. Citation Tracking /
Searching
Collating this info is difficult
and not all databases or
websites do it
Web of Science
Scopus
Google Scholar / Publish or
Perish
12. Research impact of individuals
Using Web of Science you can find out
an individual’s:
- top cited work
- what journals they have published in
- who is citing them
- their H-index
13. H-Index
Developed by Hirsh in 2005:
"An index to quantify an individual's scientific research output,"
Proceedings of the National Academy of Sciences,
102(46):16569-16572, November 15, 2005
www.pnas.org/cgi/reprint/102/46/16569
Means to evaluate research output
Based on number or publications and
the number of citations per publication
For example, an h-index of 10 means
that there are 10 published papers that
have 10 citations or more
14. Research impact of
individuals: Example
Charles K Kao, Nobel Laureate for
Physics, 2009
◦ "Father of Fiber Optic Communications"
Lets search Web of Science for Kao CK
What are his key works?
Where has he published?
What fields have been citing him?
What’s his H-Index?
15. H-Index
Some high ranking physicists:
Martin Cohen, Berkeley 94
Philip Anderson, Princeton 91
Edward Witten, Princeton
110 (world’s highest)
But…
Charles K Kao (Nobel laureate,
physics, 2009) 6
Why? Mainly published in EE conferences,
monographs and patents.
16. H-Index
Mohamed El Naschie has an impressive H-Index of 33.
But why? Check his citations in Web of Science

18. Use and Abuse
Potential for manipulation
◦ Self-citations
◦ Strategy to improve one’s citations and H-
index
19. H-Index
A scientist may artificially increase his/her
H-index by
(1) Self citation
(2) Double Publications
(3) Conference papers
(4) Citation club
(5) Coercive citation
20. Self citations
Thomson Reuters considers self-citation
beyond 20% as suspect of abuse
Famous people:
El-Naschie: 50%
Nelson Tansu: 55%

This paper has 28 self references to Tansu
176 self citations from 6 papers in a single SPIE Conference
27. Citation Club
Of the 31 papers not written by El Naschie in a issue
of Chaos, Solitons and Fractals, at least 11 are
related to his theories and include 58 citations of his
work in the journal.
Ji-Huan He, the journal's regional editor for China,
also cites El Naschie's work frequently.
An issue of the journal has one paper by He that cites
himself 14 times and El Naschie twice.
He is also editor of the International Journal of
Nonlinear Sciences and Numerical Simulation, which
in a 2005 editorial said: "Men of genius like Einstein
and Elnaschie very often ask some straightforward
and seemingly innocent questions, which may turn
out to have undreamed of answers."

contribute to the evaluation of research
quality when used appropriately – must
be aware of their limitations!
