US Patent 8938434 Household grouping based on public records

Records are obtained from various sources, including public records, and are then augmented and grouped. At least one augment key is applied to each of the records resulting in an augment key value for each record. The records are augmented based on the key value. Augmenting the records includes combining the fields of the common records into a single record and then removing the duplicate records. The augmented records are then grouped according to household. At least one household grouping key is applied to each of the augmented records resulting in a household grouping key value for each record. The records having the same household grouping key value are displayed as a household grouping.
