Taken from the report: Europe's most important and actively
publishing research institutions: Update
Data: ISI, CWTS (Treatments)
Note: Period for publications and citations 1993-1999,
citations excluding author self-citations. The overall
relative citation impact score represents the aggregate
of all broad scientific fields. On the level of broad
fields, only those institutions have been taken into account
which surpassed an output threshold of at least 70 publications
during the period.
green: most actively publishing
institution in field by country
lila: at least 25 % of total
publication output across the 11 broad fields is within
the marked field
red: highest number of citations
in field by country
yellow: impact above world
average ( 1.20)
orange: highest impact score
in country by field, but below 1.20
What are the changes, what do they imply?
The problem with the publication and citation data for
the identified Belgian institutions centered on the partition
of publications for the Dutch speaking 'Katholieke Universiteit
Leuven' (KUL), based in Leuven, and the French speaking
'Université Catholique de Louvain' (UCL), based
in Louvain-la-neuve. In the printed version, a total of
15.420 publications were attributed to the KUL, and only
3.914 to the UCL. The respective publications produced
respective citation counts and impact factors. As this
did not refllect the reality as perceived by some Belgian
higher education actors, a data check was made by CWTS
and the fault detected.
As a result of the revision, in particular the decreasing
numbers in the fields of biomedical sciences, clinical
medicine and earth & environmental sciences, KUL has
lost the position as most actively publishing institution
in these fields to the Free University Brussels*. It has
equally lost its position in terms of highest number of
citations in earth & environmental sciences and chemistry
to Free University Brussels* and UCL. In terms of the
indicators impact and 25% output in one field across the
11 broad fields, changes occur in the fields mentioned
above and involve KUL, UCL, and the University Liège.
On the university level, KUL has 'lost' in terms of number
of publications but gained in impact. The reverse is true
for the UCL.
* Note that the Free University of Brussels here contains
of two seperate universities: the Vrije Universiteit Brussel
(VUB) and the Université Libre de Bruxelles (ULB).
The Dutch and the French speaking universities are on
the same premises and unfortunately are aggregated under
their English name by the database owner Thompson-ISI.
