English abstract

Title: The Journal Citation Reports (SCI edition) with and without journal selfcitations. Journals are ranked in the subject categories of the Journal Citation Reports (JCR) according to their impact factors (JIF). The calculation of this indicator includes both citations received from other journals and self-citations from the journal itself. In this paper the current model of the JCR is compared with an alternate model using the JIF without self-citations as a variable. In order to do this, simulations were carried out using JIF without self-citations as an alternative variable. We studied the relationship between the two variables (JIF with self-citations and JIF without self-citations), the gain obtained by the journals with the usual JIF with self-citations, the changes in the ranking in the whole JCR, and changes in the internal ranking in the JCR’s subject categories. A small negative correlation was found between the gain that the journals obtained and their JIF. The results obtained suggest that if JIF without self-citations were used as the variable, the ranking of journals in the JCR and within the subject categories would be, in general, very different from the current one. The quantification of these differences is one of the more interesting results of this work.

Spanish abstract

En general las revistas se ordenan en las categorías de los Journal Citation Reports (JCR) en función de sus factores de impacto (FI). Para el cálculo de este indicador se cuentan tanto las citas recibidas desde otras revistas como las autocitas de la propia revista. En este trabajo se compara la situación actual de los JCR (edición SCI, Science Citation Index) con la que ocurriría si se calculara el FI sin autocitas como variable para ordenar las revistas. Para ello se hacen simulaciones con esta variable alternativa. Se ha estudiado la relación entre las dos variables (FI con autocitas y FI sin autocitas), la ganancia que obtienen las revistas con el FI habitual con autocitas, los cambios en la ordenación en los JCR y los cambios de ordenación internos en las categorías en que están divididos. Se ha encontrado una pequeña correlación negativa entre la ganancia que obtienen las revistas y su FI. Por otra parte, los resultados obtenidos sugieren que la ordenación de los JCR y de las categorías si se utilizase el FI sin autocitas serían en general muy diferentes a la actual. La cuantificación de estas diferencias es uno de los resultados de este trabajo que se estiman más interesantes.
