A method for processing user input includes the step of receiving, during a session, via one of a plurality of media gateways, from a user, an expression having a semantic structure. The semantic structure of the expression is evaluated. An expression type is identified, responsive to the evaluation of the semantic structure. Based on the expression type, a response to the expression is generated. A determination is made as to whether to store the received expression, the response, and an identification of the user.
