Detecting and Measuring Risk with Predictive Models Using Content Mining
First Claim
1. A system for detecting risk in a transaction, comprising the steps of:
- a database of unique merchant names, each merchant name associated with a merchant cluster and each merchant name is textual data or other high categorical data;
a transaction processing component that receives a transaction between a consumer and a entity, that derives transaction data from the transaction, and determine a unique entity identity for the entity from the database; and
a statistical model that receives the data derived from the transaction and the unique entity identity, and outputs a score indicative of the level of risk in a transaction.

Abstract
Computer implemented methods and systems of processing transactions to determine the risk of transaction convert high categorical information, such as text data, to low categorical information, such as category or cluster IDs. The text data may be merchant names or other textual content of the transactions, or data related to a consumer, or any other type of entity which engages in the transaction. Content mining techniques are used to provide the conversion from high to low categorical information. In operation, the resulting low categorical information is input, along with other data, into a statistical model. The statistical model provides an output of the level of risk in the transaction. Methods of converting the high categorical information to low categorical clusters, of using such information, and other aspects of the use of such clusters are disclosed.

2. A method of determining a level of risk in a transaction, the method comprising:
-
receiving a transaction between a first entity and a second entity; deriving high categorical information elements from at least one of transaction, the first entity or the second entity, wherein the high categorical information elements are text data; determining a low categorical information cluster closest to the high categorical information elements; and applying the low categorical information cluster and data derived from the transaction to a predictive model, and outputting the level of risk in the transaction to detect if the transaction is fraudulent. - View Dependent Claims (3, 4)

5. A computer implemented method for determining a level of risk of a transaction between a consumer and an entity, comprising the steps of:
-
storing a plurality of entity clusters, the entity clusters determined from statistical co-occurrences of the entity identified in a plurality of transactions, wherein said entity identified are entity identifiers or other high categorical data; receiving data from said transaction between said consumer and said entity; determining one of the plurality of entity clusters associated with the entity of the transaction based on the entity'"'"'s identity, wherein said entity'"'"'s identity is an entity identifier or other high categorical data; and applying the entity cluster in conjunction with data derived from the transaction to a predictive model, and outputting a level of risk of the transaction to detect if the transaction is fraudulent. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A computer implemented method for determining a level of risk of a transaction between a consumer and an entity, comprising the steps of:
-
storing a plurality of entity clusters, the entity clusters determined from statistical co-occurrences of the entity identities in a plurality of transactions, wherein said entity identities are entity identifiers or other high categorical data; receiving data from said transaction between said consumer and said entity; determining one of the plurality of entity clusters associated with the entity of the transaction based on the entity identity, wherein said entity'"'"'s identity is an entity identifier or other high categorical data; determining an affinity measure of an affinity of a consumer to the entity cluster; and applying the affinity measure in conjunction with data derived from the transaction to a predictive model, and outputting the level of risk of the transaction to detect if the transaction is fraudulent. - View Dependent Claims (18, 19, 20)

21. A method of determining the level of risk in a transaction by a consumer, comprising the steps of:
-
storing a plurality of entity clusters, the entity clusters determined from statistical co-occurrences of the entity identities in a plurality of transactions, wherein said entity identities are entity identifiers or other high categorical data; receiving data of a current transaction between a consumer and entity; determining a predicted entity cluster in which the consumer is predicted to have a future transaction based on transactions of the consumer prior to the current transaction; determining an actual entity cluster associated with the entity of the transaction based on the entity identity, wherein said entity identity is an entity identifier or other high categorical data; determining a difference measure between the predicted entity cluster and the actual entity cluster; and applying the difference measure in conjunction with data derived from the transaction to a predictive model, and outputting the level of risk of the transaction to detect if the transaction is fraudulent.
