Explanation of Ranking System Used

Publications are classified according to four ranking databases:
  • the JCR listings (using for each publication venue the average position in the list in 1998-2008)
  • the CORE listings, and
  • the CiteSeer impact listings (see also the upgraded CiteSeerX listing).
Each of these databases (except CORE) maps venues to a number between 0 and 1 (or 0 and 100%) which corresponds to the position of the corresponding venue divided by the total number of ranked venues (the lower the position the better). CORE classifies venues, instead, into four discrete ranking categories: A+ (or A*), A, B and C. In order to have a numerical figure with which to compare to the other databases and be able to compute an average value, we have mapped CORE conference rankings A to 33.0%, B to 64.0% and C to 100.0%, and CORE journal rankings A* to top 5%, A to 20%, B to 64% and C to 100%. We obtain an overall numerical ranking for each publication as the average of all available rankings for the corresponding venue (some venues do not appear in all ranking databases). Finally, publications are classified according to this average. Publications with average ranking 0-33% are considered as first level, 33-66% are considered as second level, and the rest are considered as third level. In the listings, for each publication we report the individual rankings available for the corresponding venue, as well as the global average position, in the form of a percentage.
