Patent ID: 7739313

Claim:
A computer implemented method for finding conjunctive clusters comprising: identifying a first group of points, wherein said first group of points is electronic data; identifying a second group of points, wherein said second group of points is electronic data; randomly drawing a first sample from said first group of points of a first predetermined size; and identifying subsets of said first sample; for each subset of said first sample of a second predetermined size perform steps comprising; identifying a subgroup of said second group of points that share an intersection with all of the points in said first sample of points; identifying a subgroup of said first group of points that share an intersection with a specified number of the points in said subgroup of said second group of points; and outputting a third group of points wherein the product of the magnitude of said subgroup of said second group and the magnitude of said subgroup of said first group is maximized, wherein one or more conjunctive clusters are found.
