1. A method for updating a classifier probability in a communication network, comprising: detecting, by a processor, a dynamic event, wherein the dynamic event comprises an emergency event; and updating, by the processor, the classifier probability in response to the dynamic event, where the classifier probability is employed by an automated system for processing a natural language input for routing a call, wherein the updating the classifier probability comprises: updating the classifier probability using data that has been collected in a predefined time period that is surrounding the dynamic event.
