Abstract:

Embodiments include apparatuses, methods, and systems for managing a data warehouse associated with an electronic payment transaction processing network. A first set of stores are active and a second set of stores are inactive in an offer program related to merchandise of a merchant. A first set of transaction records for a first set of transactions from the first set of stores and a second set of transaction records for a second set of transactions from the second set of stores are obtained. A first set of operations on the data warehouse for the first set of transaction records and a second set of operations on the data warehouse for the second set of transaction records may be performed. The second set of operations, different from the first set of operations, includes an update operation on the data warehouse. Other embodiments may also be described and claimed.

G06Q 20/42

Abstract:

Payment instruments used on behalf of a sponsor may be restricted from use at certain locations. The sponsor may indicate that use of the payment instrument at either specific merchants or certain categories of merchants is not in accordance with the sponsor's goals or values. A system evaluates every transaction request to determine if the personal account number of the payment instrument is associated with the sponsor. If so, the transaction may be further screened to determine if the transaction is from a location to be blocked, in which case a flag may be added to the transaction indicating it is from blocked location. An issuer of the payment instrument may then determine whether to approve or deny the transaction. A tool may generate a dataset of locations and/or merchant categories for use in identifying blocked locations.

International Classification:

G06Q 20/30
G06N 20/00

Abstract:

A system and method may retrieve transaction data for a plurality of electronic payment system transactions. The transaction data may describe a plurality of electronic payment transactions between a payment network system and a plurality of merchants. The transaction data may include a transaction location and a merchant store number. The system and method may parse the transaction data to identify the transaction location and the merchant store number and analyze the retrieved and parsed transaction data to identify one or more centroids for at least a portion of the retrieved and parsed transaction data. The one or more centroids may correspond to a merchant location for each transaction of the retrieved and parsed transaction data. The system and method may then clean the retrieved and parsed transaction data having a transaction location outside a threshold distance from the one or more centroids to include accurate merchant store number data.

G06F 16/2458

Abstract:

Provided is a method for managing source identifiers of clustered records, which may include receiving a plurality of records, each having identification data associated with a source thereof. The records may be sorted into a first plurality of clusters. A first source identifier may be generated for each cluster. Update data associated with an update to the records may be received. At least some of the records may be sorted into a second plurality of clusters. A first cluster of the second plurality of clusters may have first identification data different from at least one cluster of the first plurality of clusters, and a second cluster of the second plurality of clusters may have identification data that substantially matches the at least one cluster. Whether to assign the first source identifier to the first or second cluster may be determined. A system and computer program product are also disclosed.
