Techniques to block records for matching

A computer-implemented method, comprising:

• receiving a data set comprising a plurality of records;
• receiving blocking variables, the blocking variables present as variables in each of the plurality of records;
• generating match codes based on the blocking variables;
• producing a plurality of blocks of records from the data set based on the match codes;
• and
• matching records within each of the plurality of blocks by performing deterministic or probabilistic entity resolution based on similar variables of the records within each of the blocks.

An apparatus, comprising:

• a processor circuit on a device;
• a configuration component operative on the processor circuit to receive a data set comprising a plurality of records and operative to receive a set of blocking variables, the blocking variables present as variables in each of the plurality of records;
• a coding component operative on the processor circuit to generate match codes based on the blocking variables;
• a blocking component operative on the processor circuit to produce a plurality of blocks of records from the data set based on the match codes;
• and
• a matching component operative on the processor circuit to match records within each of the plurality of blocks by performing deterministic or probabilistic entity resolution based on similar variables of the records within each of the blocks.
