According to the January 2018 Edition of the
Webometric Ranking, out of the over 25,000
higher Institutions in the World and 209
Higher instutions ranked in Nigeria only a
handful of 23 Universities (representing
11%)in Nigeria made top 5,000 in the World.
The Top 23 Universities which were led by the
University of Ibadan with a Global rank of
1099 followed in Second place by Covenant
University, Ota with 2,142 Global rank and
coming in Third place was Obafemi Awolowo
University.
The Top 23 Universities were dominated by 19
Federal Universities, 3 state Universities and 2
private Universities.
Covenant University Ota remained the Only
non – federal university in the top 10 ranking.
On the African Stage the University of
Capetown remained number 1 with a 290
Global rank while University of Ibadan ranked
11th place while Covenant University came in
at 34th.
Also worthy of note is that the Openness
indicator of Webometrics rated the University
of Nigeria, Nsukka in the latest edition of the
ranking as the most cited University in Nigeria
by Universities across the Globe.
In comparison to South Africa, Kenya and
Ghana Nigeria Universities were poorly
represented in the top 40 rankings in Africa.
The dismal performance of over 89% of
Nigerian Universities who couldn’t make top
5,000 could mostly be as a result of more
emphasis in the Excellence indicator of the
Webometric Ranking (which rates the top 10%
highly cited researchers in 26 disciplines)
which saw Excellence increase from 30-35%
and a decrease of Presence from 10-5%.
Methodology of the Webometric Ranking
Webometrics uses link analysis for quality
evaluation as it is a far more powerful tool
than citation analysis or global surveys. In the
first case, bibliometrics only counts formal
recognition between peers, while links not
only includes bibliographic citations but also
third parties involvement with university
activities. Surveys are not a suitable tool for
World Rankings as there is not even a single
individual with a deep (several semesters per
institution), multi-institutional (several dozen),
multidisciplinary (hard sciences, biomedicine,
social sciences, technologies) experience in a
representative sample (different continents)
of universities worldwide.
Research output is also key topic for
Webometrics, but including not only formal (e-
journals, repositories) publications but also
informal scholarly communication. Web
publication is cheaper, maintaining the high
standards of quality of peer review processes.
It could also reach much larger potential
audiences, offering access to scientific
knowledge to researchers and institutions
located in developing countries and also to
third parties (economic, industrial, political or
cultural stakeholders) in their local
community.
