Generalizing a segment from user data attributes

An apparatus for data processing, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify a subset of a plurality of data attributes associated with a user identifier of a plurality of user identifiers stored in a data storage system;
• generate at least one expression for one or more of the subset of data attributes, wherein the at least one expression includes a normalization function corresponding to at least one of the one or more of the subset of data attributes, wherein the normalization function identifies correlated data attribute values to an data attribute value of the at least one of the one or more of the subset of data attributes;
• and
• query the data storage system to identify additional user identifiers using the at least one expression, wherein the expression identifies the additional user identifiers based on data attributes associated with the additional user identifiers.

A non-transitory computer-readable medium storing code for data processing, the code comprising instructions executable by a processor to:

• identify a subset of a plurality of data attributes associated with a user identifier of a plurality of user identifiers stored in a data storage system;
• generate at least one expression for one or more of the subset of data attributes, wherein the at least one expression includes a normalization function corresponding to at least one of the one or more of the subset of data attributes, wherein the normalization function identifies correlated data attribute values to an data attribute value of the at least one of the one or more of the subset of data attributes;
• and
• query the data storage system to identify additional user identifiers using the at least one expression, wherein the expression identifies the additional user identifiers based on data attributes associated with the additional user identifiers.
