Systems and methods of selecting content based on aggregate entity co-occurrence

A system for refining content selection criteria to facilitate content selection via a computer network comprising:

• a tool comprising one or more servers and one or more processors;
• an aggregator of the tool to identify content selection criteria including a first entity used to select content of a first content provider, the first entity corresponding to a canonical stable identifier in a database and having an attribute and a relationship to at least one other entity stored in the database;
• the aggregator of the tool to identify a plurality of sets of entities that each comprise the first entity and an additional entity different from the first entity, each of the plurality of sets of entities associated with content of a corresponding content provider;
• an entity evaluator of the tool to determine a performance metric for the additional entity;
• a selection criteria generator of the tool to compare the performance metric with a performance threshold;
• and
• the content selection criteria generator of the tool to associate, based on the comparison, the additional entity with the content of the first content provider.

A non-transitory computer-readable storage medium comprising processor executable instructions to refine content selection criteria to facilitate content selection via a computer network, the instructions comprising instructions to:

• identify content selection criteria including a first entity used to select content of a first content provider, the first entity corresponding to a canonical stable identifier in a database and having an attribute and a relationship to at least one other entity stored in the database;
• identify a plurality of sets of entities that each comprise the first entity and an additional entity different from the first entity, each of the plurality of sets of entities associated with content of a corresponding content provider;
• determine a performance metric for the additional entity;
• compare the performance metric with a performance threshold;
• and
• associate based on the comparison, the additional entity with the content of the first content provider.
