Abstract: An event notification matching system, including an event matching table forming a plurality of nodes. Each node is assigned a subscriber request value and contains identifiers for one or more subscribers to be notified at the occurrence of an event relating to the subscriber request value. The event notification matching system may also include a table index. The table index receives input values from an event processing module and selects one or more of the nodes that have subscriber request values corresponding to the received input values. The event processor receives event data from a predetermined source, and formats the input values to simplify the operations performed by the event matching table. The event notification matching system is configured such that the event data need not be compared to non-matching nodes in the event matching table.

Abstract: Systems and methods are provided for ensuring timely receipt of advertisements in response to an advertisement request. In one embodiment, a method includes identifying a base request from an advertisement requester; identifying a total response time allowed to process the base request, wherein the total response time allowed includes a preprocessing period before the base request is sent to an advertisement supplier; a fetch period to send the request to the advertisement supplier and receive advertisements from the advertisement supplier; and a postprocessing period to process the advertisements obtained from the advertisement supplier and send the advertisements to the advertisement requester; and monitoring the processing of the base request to determine whether the advertisements are received and sent to the advertisement requester within the total response time allowed.

Abstract: Systems and methods are provided for increasing user response to advertisements. Embodiments include an optimization engine configured to identify a request from a requester; identify at least one potential keyword associated with the request; associate the at least one potential keyword with at least one criteria bin; and identify at least one keyword from the at least one criteria bin based on a weight given the at least one criteria bin; and a routing system communicating with the requester and a supplier, the routing system also communicating with the optimization engine, the routing system configured to dynamically alter the base request with the at least one keyword to form an altered request; and send the altered request to the supplier.
