Abstract

A system and method is provided for updating customer profiles based on current information on merchant transactions performed by the customers. The customer profiles, which include data fields for customer attributes, are stored in a profile data base. The customer profiles may be updated when a batch of merchant-customer transaction reports in a given time period becomes available. The information in the batch of merchant-customer transaction reports, which may be supplemented with additional known information on the merchants and/or customers, is sorted by customer account number. The customer profiles then are updated, one customer account number at time, using the sorted information. Profiling models which relate transaction types or characteristics to customer attributes are used to assign updated values to the customer attribute data fields.

Claims

1. A method for transaction-based profiling of a customer, the method comprising:

preparing a transaction data file comprising transaction data for transactions performed by a customer with merchants in a predetermined time period;

obtaining a profile of said customer, said profile comprising a time-sensitive variable having a numerical value;

periodically calculating an updated numerical value based on the numerical value of said time-sensitive variable obtained from said profile, a time function, and said transaction data;

assigning using a specially programmed processor said updated numerical value to said time-sensitive variable;

using said updated numerical value to identify at least one target customer having a predetermined characteristic; and

transmitting a marketing communication to said at least one target customer, wherein said time function comprises an exponential decay time function defined as;

x=xe<sup>−

kδ</sup>

+y

wherein x is said time-sensitive variable, k is an aging constant, δ

is a time variable based on a last qualifying transaction performed by the customer, and y is an incrementing variable.

2. The method of claim 1, wherein said time-sensitive variable comprises behavioral information.

3. The method of claim 1, wherein said time-sensitive variable comprises a confidence level.

4. The method of claim 1, wherein said time function decays the numerical value of said time-sensitive variable to a steady state numerical value when a qualifying transaction is not reported within a stated time period.

5. The method of claim 1, wherein said time function resets or increments the numerical value of said time-sensitive variable when a qualifying transaction is reported within a stated time period.

6. The method of claim 1, wherein k is chosen such that x decays to zero when δ

exceeds a stated time period.

7. The method of claim 1, wherein said time-sensitive variable is updated with each of the transactions performed by the customer reflected in said transaction data file.

8. The method of claim 1, wherein said time-sensitive variable is updated with each of the transactions performed by the customer reflected in a transaction batch.

9. The method of claim 1, wherein preparing the transaction data file comprises:

receiving merchant transaction reports with merchant information from a merchant account data warehouse; and

augmenting said merchant transaction reports with said merchant information from said merchant account data warehouse.

10. The method of claim 1, wherein obtaining said profile of said customer comprises retrieving customer account information from a customer account data warehouse.

11. The method of claim 1, wherein obtaining said profile of said customer comprises creating a new customer profile for said customer.

12. A system for updating a profile of a customer of a business in a batch process, said system comprising:

one or more processors configured to prepare a transaction data file comprising transaction data for transactions performed by a customer with merchants in a predetermined time period;

said one or more processors further configured to obtain a profile of said customer, said profile comprising a time-sensitive variable having a numerical value;

said one or more processors further configured to periodically calculate an updated numerical value based on the numerical value of said time-sensitive variable obtained from said profile, a time function, and said transaction data; and

said one or more processors further configured to assign said updated numerical value to said time-sensitive variable,

wherein said time function comprises an exponential decay time function defined as;

x=xe<sup>−

kδ</sup>

+y

wherein x is said time-sensitive variable, k is an aging constant, δ

is a time variable based on a last qualifying transaction performed by the customer, and y is an incrementing variable.

13. The system of claim 12, wherein said one or more processors are further configured to use said updated numerical value to identify at least one target customer having a predetermined characteristic.

14. The system of claim 13, wherein said one or more processors are further configured to transmit a marketing communication to said at least one target customer.

15. The system of claim 12, wherein said time-sensitive information comprises behavioral information.

16. The system of claim 12, wherein said time-sensitive variable comprises a confidence level.

17. The system of claim 12, wherein said one or more processors are further configured to store the updated profile in a profile database.

18. The system of claim 12, wherein said one or more processors are further configured to retrieve customer account information from a customer account data warehouse.

19. The system of claim 12, wherein said one or more processors are further configured to create a new customer profile for said customer.

20. The system of claim 12, wherein k is chosen such that x decays to zero when δ

exceeds a stated time period.

21. A non-transitory computer readable medium encoded with a computer program that includes computer executable instructions for updating a profile of a customer of a business in a batch process, which when executed causes a processing system to perform the steps of:

preparing a transaction data file comprising transaction data for transactions performed by a customer with merchants in a predetermined time period;

obtaining a profile of said customer, said profile comprising a time-sensitive variable having a numerical value;

periodically calculating an updated numerical value based on the numerical value of said time-sensitive variable obtained from said profile, a time function, and said transaction data; and

assigning using a specially programmed processor said updated numerical value to said time-sensitive variable,

wherein said time function comprises an exponential decay time function defined as;

x=xe<sup>−

kδ</sup>

+y

wherein x is said time-sensitive variable, k is an aging constant, δ

is a time variable based on a last qualifying transaction performed by the customer, and y is an incrementing variable.

22. The non-transitory computer-readable medium of claim 21 wherein the computer program further causes the processing system to perform the step of using said updated numerical value to identify at least one target customer having a predetermined characteristic.

23. The non-transitory computer-readable medium of claim 22 wherein the computer program further causes the processing system to perform the step of transmitting a marketing communication to said at least one target customer.

24. The non-transitory computer-readable medium of claim 21 wherein the computer program further causes the processing system to perform the step of storing the updated profile in a profile database.

25. The non-transitory computer-readable medium of claim 21 wherein the computer program further causes the processing system to perform the step of retrieving customer account information from a customer account data warehouse.

26. The non-transitory computer-readable medium of claim 21 wherein the computer program further causes the processing system to perform the step of creating a new customer account profile for said customer.

27. The non-transitory computer-readable medium of claim 21, wherein k is chosen such that x decays to zero when δ

exceeds a stated time period.

28. A method for transaction-based profiling of a customer, the method comprising:

preparing a transaction data file comprising transaction data for transactions performed by a customer with merchants in a predetermined time period;
