    Abstract: A system and method for monitoring telephone calls to detect fraudulent activity and take corrective action is described. The system receives a group of telephone calls having associated call characteristics and analyzes the group of telephone calls to identify and store a first set of distributions of call characteristics that are indicative of normal activity, fraudulent activity, or indeterminate activity. The system receives one or more subsequent telephone calls to be analyzed. The system analyzes the received one or more telephone calls to identify a second set of distributions of call characteristics associated with the received telephone call. The system then compares the second set of distributions of call characteristics to the stored first set of distributions of call characteristics to assess a probability that the one or more received telephone calls represents normal, fraudulent, or indeterminate activity. If the assessed probability of fraudulent activity exceeds a threshold, the system takes appropriate corrective action, such a flagging the fraudulent call or withholding a financial incentive associated with the fraudulent call.

    Abstract: A facility and method for analyzing and classifying calls without transcription via keyword spotting is disclosed. The facility uses a group of calls having known outcomes to generate one or more domain- or entity-specific grammars containing keywords and related information that are indicative of particular outcome. The facility monitors telephone calls by determining the domain or entity associated with the call, loading the appropriate grammar or grammars associated with the determined domain or entity, and tracking keywords contained in the loaded grammar or grammars that are spoken during the monitored call, along with additional information. The facility performs a statistical analysis on the tracked keywords and additional information to determine a classification for the monitored telephone call.

    Abstract: A method and system that performs cross-channel advertisement targeting based on consumer telephone numbers. The system utilizes a targeting database to determine which consumers should be re-engaged on behalf of a business. The targeting database correlates a telephone number associated with a consumer with a masked user identifier associated with the tracking of online behavior of that consumer. The targeting database may include a confidence level representing the likelihood of correspondence between the telephone number and masked user identifier. The targeting database is used by the system to target advertisements to consumers. A telephone number of a consumer is used to identify a masked identifier of the consumer. Advertisements are then targeted to the consumer using the masked identifier. The stored confidence level may be used by the system to control the aggressiveness of re-targeting.
