The present invention discloses a method, a computer system, a computer readable
medium and a sever. The method of the present invention comprises steps of; creating
said document matrix from said documents using at least one attribute; creating
a scaled residual matrix based on said document matrix using a predetermined function;
executing singular value decomposition to obtain a basis vector corresponding to
the largest singular value; re-constructing said residual matrix and scaling dynamically
said re-constructed residual matrix to obtain another basis vector; repeating said
singular value decomposition step to said re-constructing step to create a predetermined
set of basis vector; and executing reduction of said document matrix to perform
detection, retrieval and identification of said documents in said database.
