5. The method of claim 1 wherein said one or more computing devices, further processing the association matrix to perform: selecting a first set of ontological subject, having at least one member; selecting a number of first associated sets of ontological subject, each of said first associated set having at least one member, wherein each of said first associated sets is corresponded to a member of the first set, wherein each member of each set of said first associated sets having association value greater than a predefined threshold with at least one member of the first set; selecting an ith set of ontological subject, having at least one member, from sets of the (i−1)th associated sets, wherein i is an integer number greater than one; selecting a number of ith associated sets of ontological subjects, wherein each set of said ith associated sets is corresponded to a member of said ith set of ontological subjects and each of it's member having association value greater than a predefined threshold with at least one member of said ith set of ontological subjects; and making one or more data structures with data thereon usable in determining the selected associated set of ontological subjects for each member of jth set of ontological subjects, wherein j is an integer number greater than or equal to one.
5. The method of claim 1 wherein said one or more computing devices, further processing the association matrix to perform: selecting a first set of ontological subject, having at least one member; selecting a number of first associated sets of ontological subject, each of said first associated set having at least one member, wherein each of said first associated sets is corresponded to a member of the first set, wherein each member of each set of said first associated sets having association value greater than a predefined threshold with at least one member of the first set; selecting an ith set of ontological subject, having at least one member, from sets of the (i−1)th associated sets, wherein i is an integer number greater than one; selecting a number of ith associated sets of ontological subjects, wherein each set of said ith associated sets is corresponded to a member of said ith set of ontological subjects and each of it's member having association value greater than a predefined threshold with at least one member of said ith set of ontological subjects; and making one or more data structures with data thereon usable in determining the selected associated set of ontological subjects for each member of jth set of ontological subjects, wherein j is an integer number greater than or equal to one. 7. The method of claim 5 , wherein an associated set of ontological subjects of an ontological subject is represented by at least one form of spectral graph having ontological subjects in one axis and showing the association value of the members of the set in another axis.
