ABSTRACT:
A facility for identifying groups of items that co-occur in more than a threshold number of instances is described. Each such group of items has a size reflecting the number of items in the group. The facility uses a data structure comprising, for each of a plurality of group sizes, a single map identifying groups of that group size that co-occur in more than a threshold number of instances.
