Expanding Attribute Profiles
First Claim
1. A computer based method 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) receiving a query attribute;
b) accessing a set of attribute profiles associated with a group of query-attribute-positive individuals;
c) accessing a set of attribute profiles associated with a group of query-attribute-negative individuals;
d) determining a first statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the set of attribute profiles associated with the group of query-attribute-positive individuals than in the set of attribute profiles associated with the group of query-attribute-negative individuals;
e) expanding one or more attributes in the set of attribute profiles associated with the group of query-attribute-positive individuals and one or more attributes in the set of attribute profiles associated with the query-attribute-negative individuals to create a set of expanded attribute profiles associated with the group of query-attribute-positive individuals and a set of expanded attribute profiles associated with the group of query-attribute-negative individuals;
f) determining a second statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the set of expanded attribute profiles associated with the group of query-attribute-positive individuals than in the set of expanded attribute profiles associated with the group of query-attribute-negative individuals; and
g) storing, when the second statistical result is higher than the first statistical result, the expanded attribute profiles associated with the group of query-attribute-positive individuals and the expanded attribute profiles associated with the group of query-attribute-negative individuals.

Abstract
A method and system for expanding attribute profiles are presented in which primary attributes from one or more attribute profiles are used to derive secondary attributes which are added to the respective attribute profiles to generate expanded attribute profiles. The expanded attribute profiles are generated to increase the strength of association of a query attribute with one or more attribute profiles associated with query-attribute-positive individuals.

8. A computer based method for expanding an attribute profile to increase the strength of association between a query attribute and the attribute profile, comprising:
-
a) accessing an attribute profile containing a set of primary attributes; b) expanding the set of primary attributes to produce a set of secondary attributes, wherein the set of secondary attributes results in a higher strength of association between a query attribute and an attribute profile containing the set of secondary attributes than between the query attribute and an attribute profile containing only the set of primary attributes; and c) storing the set of secondary attributes in association with the attribute profile to create an expanded attribute profile. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A computer based system 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) a data receiving subsystem for receiving a query attribute; b) a data accessing subsystem for accessing; i) a set of attribute profiles associated with a group of query-attribute-positive individuals; ii) a set of attribute profiles associated with a group of query-attribute-negative individuals; c) a data processing subsystem comprising a data conversion subsystem for expanding one or more attributes in the set of attribute profiles associated with the group of query-attribute-positive individuals and one or more attributes in the set of attribute profiles associated with the query-attribute-negative individuals to create a set of expanded attribute profiles associated with the group of query-attribute-positive individuals and a set of expanded attribute profiles associated with the group of query-attribute-negative individuals; d) a statistical computation subsystem for; i) calculating a first statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the set of attribute profiles associated with the group of query-attribute-positive individuals than in the set of attribute profiles associated with the group of query-attribute-negative individuals; ii) calculating a second statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the set of expanded attribute profiles associated with the group of query-attribute-positive individuals than in the set of expanded attribute profiles associated with the group of query-attribute-negative individuals; and e) a data storage subsystem for storing, when the second statistical result is higher than the first statistical result, the expanded attribute profiles associated with the group of query-attribute-positive individuals and the expanded attribute profiles associated with the group of query-attribute-negative individuals.
