Abstract: A computing system is described that determines, based on survey information, a group of users of computing devices who have expressed interest in an event, wherein the group of users is included in a plurality of users, and wherein each of the plurality of users has an interest profile. The computing system also determines, based on the interest profiles for each of the users in the group of users, one or more interests indicating interest in the event, and identifies, based on the one or more interests indicating interest in the event, a user not included in the group of users that has an interest profile including the one or more interests indicating interest in the event. The computing system also transmits, to a computing device associated with the user, information about the event.

Abstract: A method and system for processing a user dialogue using dialogue-state objects. The method and system are implemented using an interactive computer system. The interactive computer system includes a dialogue manager and application control logic. The method includes the step of providing a plurality of objects encapsulating dialogue data and dialogue procedures associated with dialogue-states. The method next includes the step of providing a pointer. The pointer identifies a first object as a current object. The method further includes the step of receiving an input signal. The method also includes the step of processing the input signal. The method finally includes the step of updating the pointer based on the step of processing such that the pointer identifies a second object as the current object.
