Claim One:
1. A method of sorting a set of electronic documents, comprising: determining, 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 reals and d is a positive integer, wherein for at least one document u 1 of said set a distance in R d between associated points X(u 1 ) and X(u 2 ), where u 2 is a document for which there is correlation between the documents u 1 and u 2 , is smaller the higher the degree of correlation between the documents u 1 and u 2 , generating a representation of said sphere and of points determined on said sphere so as to enable an operation of sorting or selection part to be performed on said set of documents as a function of the points determined on said sphere.
