1. A computer, said computer including a display driver device, a memory, a central processor, and computer readable media with executable instructions thereon, for expanding attribute profiles to increase the strength of association between a query attribute and a set of attribute profiles associated with query-attribute-positive individuals, comprising:

  • a) means for receiving a query attribute which identifies, within an initial set of attribute profiles contained in said computer memory, a 1st dataset comprising a set of query-attribute-positive attribute profiles associated with query-attribute-positive individuals and a set of query-attribute-negative attribute profiles associated with query-attribute-negative individuals;

    b) means for identifying a 1st subgroup of query-attribute-positive attribute profiles from the 1st dataset of query-attribute-positive attribute profiles and a 2nd subgroup of query-attribute-negative attribute profiles from the 1st dataset of query-attribute-negative attribute profiles;

    c) means for generating a 1st set of one or more attribute combinations by sequential comparison of each of the 1st dataset of query-attribute-positive attribute profiles with each of the 1st dataset of query-attribute-negative attribute profiles;

    d) means for determining a 1st statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the 1st subgroup of query-attribute-positive attribute profiles than in the 2nd subgroup of query-attribute-negative attribute profiles;

    e) means for expanding one or more attributes in the 1st subgroup of query-attribute-positive attribute profiles and one or more attributes in the 2nd subgroup of query-attribute-negative attribute profiles to generate a 3rd subgroup of expanded query-attribute-positive attribute and a 4th subgroup of expanded query-attribute-negative attribute profiles wherein expanding one or more attributes results in the creation of attributes not initially contained within the set of attribute profiles;

    f) means for generating a 2nd set of attribute combinations by sequential comparison of each of the 3rd subgroup of expanded query-attribute-positive attribute profiles with each of the 4th subgroup of expanded query-attribute-negative attribute profiles;

    g) means for determining a 2nd statistical result indicating strength of association of the query attribute with an attribute combination from the 2nd set of attribute combinations which has a higher frequency of occurrence in the 3rd subgroup of expanded query-attribute-positive attribute profiles than in the 4th subgroup of expanded query-attribute-negative attribute profiles; and

    h) means for storing within said computer memory, based on the attribute combination of step (g) when the 2nd statistical result is higher than the 1st statistical result, a 3rd set of expanded query-attribute-positive attribute profiles associated with the query-attribute-positive individuals and a 4th set of expanded query-attribute-negative attribute profiles associated with the query-attribute-negative individuals.
