1. A method of classifying data by aggregating emerging patterns in said data using datasets for a plurality of classes using a computer processor, said method including the steps of:

  • for each of said classes, mining an emerging pattern set dependent upon instances of said set and opponent instances dependent upon predetermined growth rate and support thresholds;

    calculating aggregate scores of said instances for all of said classes;

    determining base scores for each of said classes; and

    for each test instance, performing the sub-steps of;

    calculating aggregate and normalised scores of test instance for each class; and

    assigning a specified class to the test instance for which the test instance has a largest normalized score;

    wherein said mining step includes the steps of;

    determining borders of large itemsets using a largeborder based technique; and

    determining supports and growth rates of emerging patterns for said class.
