  • Publication number: 20250103638
    Abstract: A mechanism for performing generalization on data records. The data records are clustered to produce one or more clusters of data records. In each cluster, any property that is attributed to a subject of any data record in the cluster is identified. An iterative process is performed for each cluster comprising processing sets of the identified properties, wherein the number of properties in a set is N, to identify any/all set(s) of properties for which between 0 and k data records have binary values that attribute all of those properties of the set to the said data records. In the cluster, the binary data value for one or more of the properties in each identified set of properties is generalized. The iterative process is repeated m times, with the value of N increasing by one for each iterative process.
