3. Citation <strong>Analysis</strong><br />
3.1 Citation Rates for the Countries Studied over the Entire Period<br />
The perception of scientific publications can be measured using citations by other scientists in<br />
the form of the average number of citations per article (citation rate). In the sciences, the<br />
Science Citation Index (SCI) is used most often as the data source for this purpose. SCI<br />
consists predominantly of internationally respected journal articles and simultaneously records<br />
their citations in the journals evaluated. The citation rate is an indicator that is independent of<br />
the size of an institution or country but not of the size of the individual discipline. This means<br />
that the citation rate is not suitable for interdisciplinary comparisons.<br />
Figures 57 to 60 show the average citation rate (entire period) for each country studied in each<br />
of the disciplines presented. The perception of different countries can be compared within a<br />
discipline. To provide a better overview, the disciplines are split into two groups and presented<br />
in two charts, as are the countries. This results in four spider charts. We can see, for example,<br />
that China is ranked quite poorly in almost all of the disciplines investigated despite a high<br />
number of publications. It is also obvious that Australia’s perception is as high as Germany’s in<br />
many disciplines despite the fact that its publication output is significantly lower.<br />
