1. A method for use in a processing system for managing a dialogue between the system and a user, the method comprising the steps of: receiving an input signal representing one of speech and text associated with at least a portion of the dialogue; processing a set of frames characterizing a subject of the dialogue, associated with the input signal, each frame including one or more properties that describe a corresponding object which may be referenced during the dialogue, wherein a weight is assigned to each of at least a subset of the properties represented by the set of frames, such that the assigned weights indicate the relative importance of the corresponding properties; utilizing the weights to determine which of a plurality of possible responses the system should generate for a given user input during the dialogue; and generating an output signal for sensory perception by the user representing at least one of the plurality of possible responses.

The method of claim 1 further including the step of determining a property about which the user will be queried in an initial system query, by computing an expected number of subsequent queries for each of the properties of one or more of the frames.
