Entity resolution techniques and systems

A system, comprising:

• at least one memory device storing computer-readable instructions;
• and
• at least one data processing device operable to execute the computer-readable instructions to perform operations including:
• estimating a joint probability of occurrence of a plurality of values of a respective plurality of descriptors of an entity, the plurality of descriptor values being included in a first data set;
• determining that the joint probability of occurrence of the plurality of descriptor values is less than a threshold probability;
• identifying a second data set including the same plurality of values of the same respective plurality of descriptors;
• and
• determining, based at least in part on the joint probability of occurrence of the plurality of descriptor values being less than the threshold probability and on the first and second data sets including the same plurality of descriptor values, that the first and second data sets describe the same entity.

A computer-readable storage medium having instructions stored thereon that, when executed by a data processing device, cause the data processing device to perform operations comprising:

• estimating a joint probability of occurrence of a plurality of values of a respective plurality of descriptors of an entity, the plurality of descriptor values being included in a first data set;
• determining that the joint probability of occurrence of the plurality of descriptor values is less than a threshold probability;
• identifying a second data set including the same plurality of values of the same respective plurality of descriptors;
• and
• determining, based at least in part on the joint probability of occurrence of the plurality of descriptor values being less than the threshold probability and on the first and second data sets including the same plurality of descriptor values, that the first and second data sets describe the same entity.
