Methods and systems for comparing customer records

Abstract:

Techniques for comparing customer records to identify linked customer records are provided. The techniques may include a computer system identifying a pair of customer records and comparing the customer records to determine if the customer records are linked records. The computer system may analyze a first set of data values from first corresponding data fields from the pair of records to determine a first distance between the first set of data values, analyze a second set of data values from second corresponding data fields from the pair of records to determine a second distance between the second set of data values, and combine the first distance and the second distance into a combined distance value which is representative of a distance between the pair of customer records by using a combination function which provides a maximum value cap for the first distance and a weight for the first distance.
