1. A method for automated classification of information in a computer system, said method comprising the steps of:

  • storing, in memory of a computer system, a knowledge catalog comprising a plurality of independent ontologies, wherein an independent ontology comprises a plurality of related categories arranged hierarchically in at least one parent-child relationship;

    processing documents, which comprise at least two topics, input to said computer system by referencing categories from at least two different independent ontologies in said memory that relate to said topics; and

    generating a classification for said documents by cross referencing said categories referenced from said different ontologies to create a classification hierarchy that comprises said two different independent ontologies, wherein cross referencing categories from different independent ontologies generates multiple permutations using different independent ontologies to create a detailed classification hierarchy that identifies a plurality of topics for said documents, while minimizing the number of categories stored as said knowledge catalog.
