Robust multichannel targeting

A system comprising:

• a hardware processor and a memory, the hardware processor configured to:
• receive profile data from a plurality of data channels,
• access an attributization rule associated with at least one of the data channels, the attributization rule comprising instructions to convert the profile data into attributes for a robust recipient profile of a recipient;
• convert, based on the attributization rule, the profile data into the attributes and store the attributes in a robust recipient profile associated with a recipient identifier of the recipient, the robust recipient profile stored in a database record in the memory in association with the recipient identifier;
• determine a recipient-specific custom metadata recommendation based on the robust recipient profile and the recipient identifier stored in the database record by:
• retrieval of metadata and an attribute configuration file from a metadata database, the metadata comprising a set of generalized metadata in the metadata database;
• match of the determined attributes in the robust recipient profile of the recipient with the metadata based on the attribute configuration file to determine relevant recipient-specific custom metadata;
• derive temporal contextual state of the recipient by applying context rules to the profile data from the plurality of data channels, the stored robust recipient profile, and API request data accompanying requests received through an API;
• and
• rank the relevant recipient-specific custom metadata based on a significance of the relevant recipient-specific custom metadata to the temporal contextual state of the recipient;
• and
• generate and transmit, as an offer output, for presentation to the recipient on a user interface of the recipient, a highest ranked recipient-specific custom metadata recommendation.

A non-transitory computer readable storage medium comprising:

• instructions executable by a hardware processor to receive profile data from a plurality of data channels, instructions executable by the hardware processor to access an attributization rule associated with at least one of the data channels, the attributization rule comprising instructions to convert the profile data into attributes for a robust recipient profile of a recipient;
• instructions executable by the hardware processor to convert, based on the attributization rule, the profile data into the attributes and store the attributes in a robust recipient profile associated with a recipient identifier of the recipient;
• instructions executable by the hardware processor to determine a recipient- specific custom metadata recommendation based on the robust recipient profile comprising:
• instructions executable to retrieve metadata and an attribute configuration file from a metadata database, the metadata comprising a set of generalized metadata in the metadata database;
• instructions executable to match the determined attributes in the robust recipient profile of the recipient with the metadata based on the attribute configuration file to determine relevant recipient-specific custom metadata;
• instructions executable to derive a temporal contextual state of the recipient by applying context rules to the stored robust recipient profile, API request data accompanying requests received through an API, or a combination of the stored robust recipient profile and the API request data;
• and
• instructions executable to rank the relevant recipient-specific custom metadata based on a significance of the relevant recipient-specific custom metadata to the temporal contextual state of the recipient;
• and
• instructions executable by the hardware processor to generate and transmit, as an offer output, for presentation to the recipient on a user interface of the recipient, a highest ranked recipient-specific custom metadata recommendation.
