Abstract: The purpose of this study is to define a bibliometric indicator of the 
scientific impact of a journal, which combines objectivity with the ability to 
bridge many different bibliometric factors and in particular the side factors 
presented along with celebrated ISI impact factor. The particular goal is to 
determine a standard threshold value in which an independent self-organizing 
system will decide the correlation between this value and the impact factor of 
a journal. We name this factor "Cited Distance Factor (CDF)" and it is extracted 
via a well-fitted, recurrent Elman neural network. For a case study of this 
implementation we used a dataset of all journals of cell biology, ranking them 
according to the impact factor from the Web of Science Database and then 
comparing the rank according to the cited distance. For clarity reasons we also 
compare the cited distance factor with already known measures and especially 
with the recently introduced eigenfactor of the institute of scientific 
information (ISI). (C) 2010 Elsevier Inc. All rights reserved.
