“…For these characteristics to be equivalent for purposes of comparison (i.e., equiparable), it was first necessary to assign them a weight according to their relevance for retrieval of any requested information. To this end, we chose a range of weights from −0.5 to 0.3, with, positive weights corresponding to those that were considered desirable characteristics and negative weights to those considered undesirable characteristics, and varied the values to make the results equiparable (a complete justification of the values is given in Faba‐Pérez, 2003 and Faba‐Pérez, Guerrero‐Bote, & Moya‐Anegón, 2004, 2005). The characteristics considered are (Faba‐Pérez et al, 2005): - New Pages .
