Abstract

The disclosed system allows a credit or charge card issuer to provide its card members with a list of merchants, products, services, vacation destinations or other offerings that might be of interest based on the purchases of similar card members. In one instance, this process looks at all card members that made purchases at a merchant and then it identifies all other merchants in the same category where those card members also made purchases. The associated merchants are ranked based on largest number of shared card members and the top results may be shared with card members or merchants in order to enhance promotions, card use and marketing.

Claims

1. A method comprising:

determining, by a computer-based ranking system, a first value for each pair of,

a first merchant of a plurality of merchants, and

each remaining merchant,

wherein the first value corresponds to a number of account holders having at least one financial transaction with the first merchant and the remaining merchants during a period of time;

determining, by the computer-based system, a second value for each of the remaining merchants of the plurality of merchants other than the first merchant, the second value corresponding to the number of account holders having at least one financial transaction with each of the remaining merchants during the period of time;

determining, by the computer-based system, a third value corresponding to a ratio of the first value to the second value;

determining, by the computer-based system, a fourth value, wherein the fourth value comprises C=A+(WI*B*(A−

W2));

wherein,

C=the fourth value

A=the first value

B=the third value

WI=a first weighting factor

W2=a second weighting factor; and

ranking, by the computer-based system, each remaining merchant based on the fourth value.

2. The method of claim 1, wherein the fourth value corresponds to the third value multiplied by a corrective factor to account for a significance of financial transactions.

3. The method of claim 2, wherein the corrective factor comprises reducing the third value based on a reduced significance of transactions occurring between the first merchant and merchants having a number of financial transactions below a threshold number with both the first merchant and each of the remaining merchants during the period of time.

4. The method of claim 3, wherein the corrective factor comprises increasing the third value based on an increased significance of transactions occurring between the first merchant and merchants having a number of financial transactions above the threshold number with both the first merchant and each of the remaining merchants during the period of time.

5. The method of claim 2, wherein the corrective factor further comprises a calculated corrective factor based on empirical data.

6. The method of claim 1, wherein the ranking further comprises ranking based on ratings of vacation destinations received from account holders.

7. The method of claim 1, further comprising offering a discount on a purchase from at least one of the remaining merchants to account holders having at least one financial transaction with the first merchant during the period of time.

8. The method of claim 1, further comprising receiving information corresponding to a plurality of merchants.

9. The method of claim 1, further comprising determining a group of the plurality of merchants based on an industry code and a geographic location.

10. The method of claim 6, wherein vacation destinations visited by the account holders are grouped using vacation destination characteristics.

11. The method of claim 1, further comprising receiving information corresponding to a number of financial transactions involving account holders during the period of time.

12. The method of claim 1, further comprising determining, for each merchant of the plurality of merchants, the financial transactions involving the account holders during the period of time.

13. The method claim 1, wherein the plurality of merchants are restaurateurs.

14. The method claim 1, wherein the plurality of merchants are restaurateurs offering similar cuisine.

15. An article of manufacture including a non-transitory, tangible computer readable medium having instructions stored thereon that, in response to execution by a computer-based ranking system, cause the computer-based system to perform operations comprising:

determining, by the computer-based system, a first value for each pair of,

a first merchant of a plurality of merchants, and

each remaining merchant,

wherein the first value corresponds to a number of account holders having at least one financial transaction with the first merchant and the remaining merchants during a period of time;

determining, by the computer-based system, a second value for each of the remaining merchants of the plurality of merchants other than the first merchant, the second value corresponding to the number of account holders having at least one financial transaction with each of the remaining merchants during the period of time;

determining, by the computer-based system, a third value corresponding to a ratio of the first value to the second value;

determining, by the computer-based system, a fourth value, wherein the fourth value comprises C=A+(WI*B*(A−

W2));

wherein,

C=the fourth value

A=the first value

B=the third value

WI=a first weighting factor

W2=a second weighting factor; and

ranking, by the computer-based system, each remaining merchant based on the fourth value.

16. A system comprising:

a processor; and

a tangible, non-transitory memory communicating with the processor for ranking

the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising;

determining, by the processor, a first value for each pair of,

a first merchant of a plurality of merchants, and

each remaining merchant,

wherein the first value corresponds to a number of account holders having at least one financial transaction with the first merchant and the remaining merchants during a period of time;

determining, by the processor, a second value for each of the remaining merchants of the plurality of merchants other than the first merchant, the second value corresponding to the number of account holders having at least one financial transaction with each of the remaining merchants during the period of time;

determining, by the processor, a third value corresponding to a ratio of the first value to the second value;

determining, by the processor, a fourth value, wherein the fourth value comprises C=A+(WI*B*(A−

W2));

wherein,

C=the fourth value

A=the first value

B=the third value

WI=a first weighting factor

W2=a second weighting factor; and

ranking, by the processor, each remaining merchant based on the fourth value.
