Citation indicator in world rankings

An interesting post by Richard Holmes about the THE university world rankings, and why the citation part of the rankings is not yet reliable. I just noticed that he withdrew the post and replaced it with an apology.

The world top 20 in the THE citation indicator rankings are

1.   Moscow (State) Engineering Physics Institute (MEPhI)
1.   Rice University
3.   University of California Santa Cruz
3.   MIT
5.   Princeton
6.   Caltech
7.   University of California Santa Barbara
7.   Stanford
9.   University of California Berkeley
10.  Harvard
11.  Royal Holloway London
12.  Chicago
13.  Northwestern
14.  Tokyo Metropolitan University
14.  University of Colorado Boulder
16.  University of Washington Seattle
16.  Duke
18.  University of California San Diego
18.  University of Pennsylvania
18.  Cambridge

The list looks slightly odd to me. I would like to know how these numbers are calculated, but I can’t find the information anywhere. It is apparently calculated by Thomson-Reuters, who use their large database of citation data to compute this number.  I would like to calculate it for my own university UCD, but I don’t know how. In 2011 UCD got 80.5 and in 2012 UCD got 74.9.  What happened to us?  The formula for calculating the number seems to be a secret, so we can’t replicate the calculation. Just accept it. We got worse between 2011 and 2012.

On a different matter, there is an interesting post by Phil Davis on the relation between impact factors and citations. There is none. [Essentially none, in my opinion.]  I made an earlier post about this, and gave links to other writings.

  2. ‘there is none’ is definitely not what Phil concludes, it’s more like ‘Lazano et al say it’s weakening, but their analysis is flawed’. Anyway, IF is calculated from average citation rate for a set of papers over a set period, so it’s hard to see how IF and citation rate could be unrelated.
