Claim One:
1. A method of sorting a set of electronic documents at a processing apparatus, comprising: determining, with a processor for each pair of documents {u,v} of said set, a degree of correlation ω(u,v) between the documents u and v; determining, for each document u of said set, an associated point X(u) situated on a sphere of the set R d where R is a set of real numbers and d is a positive integer, wherein for at least one document u 1 of said set a distance in Rd between associated points X(u 1 ) and X(u 2 ), the distance being smaller relative to an increase in the degree of correlation between the documents u 1 and u 2 , where u 2 is a document for which there is correlation between the documents u 1 and u 2 ; and generating a representation of said sphere and of points determined on said sphere to enable an operation of sorting or selection to be performed on said set of documents as a function of the points determined on said sphere.
