1. A system for compound feature determination, comprising: a computer having a processor and a memory, the memory having a database of known features associated with the compound feature; the memory further containing stored programming instructions operable by the processor to determine whether the compound feature is present for a given data element within a data set, the presence of the compound feature being a function of a Boolean logical operator association between a plurality of known features associated with the compound feature wherein the stored programming instructions further enable the processor to determine the presence of the compound feature as a function of a plurality of hit weight values, each one of the plurality of hit weight values being assigned to a corresponding one of the plurality of known features, wherein the compound feature is determined to be present if the sum of the hit weights is equal to or greater than a user-defined threshold for the Boolean operation.
