Abstract: Certain aspects of the present disclosure provide techniques for updating a policy of an agent, including receiving a first transaction file associated with an entity; predicting, by the agent, an expected reward for each respective string of a plurality of strings associated with the first transaction file based on a policy of the agent, wherein the policy is determined based on a context comprising at least an attribute of the entity; determining a first string based on a highest expected reward; providing, to an environment, the first string; receiving a response to the first string, wherein the response comprises an actual reward; and updating the policy of the agent based on the response to the first string.

Abstract: A method for determining relevancy of real time received terms, the method includes the steps of: determining relevancy keywords; extracting real time terms from currently received information streams; updating current reception patterns of relevancy keywords in response to a comparison between the extracted real time terms and the relevancy keywords; and determining a relevancy of relevancy keywords in response to a comparison between current reception patterns and reference reception patterns.

Abstract: An apparatus for notification of a failed prepaid call, initiated in a telephony network by a calling party to a called party, including: a failed prepaid call data capturer, deployed in the telephony network, configured to capture data pertaining to the failed prepaid call from the network, and a notifier, associated with the failed prepaid call data capturer, configured to automatically notify the called party about the failed prepaid call, using the captured data.

Abstract: A system and method for determining relevancy of real time received terms, the method includes the steps of: determining relevancy keywords; extracting real time terms from currently received information streams; updating current reception patterns of relevancy keywords in response to a comparison between the extracted real time terms and the relevancy keywords; and determining a relevancy of relevancy keywords in response to a comparison between current reception patterns and reference reception patterns.

Abstract: A method and apparatus for providing a telephone subscriber with data of incomplete video calls is presented. A determination unit detects an incomplete video call, possibly by receiving a signal from a telephone switch, by receiving a signal from a video mail system or by monitoring the operation of the network exchange switch. An interrogation unit then obtains call data which indicates the calling party, and may give further details of the missed video call. The data is stored in a format for forwarding to the called party, preferably as an MMS. If call data is provided for all call types (such as both voice and video), the determination unit may also determine that a given call is a video call based on a call type indicator.
