1. An interactive system, comprising:
- a component to assess reliability of a communication; and
a component to infer a probability associated with one or more intentions of the communication; and
a plurality of candidate utterances are defined for each intention; and
the plurality of candidate utterances are analyzed according to a Bayesian network model, the model is determined over different instances of time to probabilistically infer a communicators intent.

Abstract
An interactive communications system is provided in accordance with the present invention. The system includes a component for analyzing sequential communications including speech, gestures and other modalities related to an underlying communicative intention. The component concurrently employs at least two of the communications in determining an action to facilitate achieving the intention.

20. An interactive system, comprising:
-
a first component for analyzing sequential communications including speech, gestures and other modalities related to one or more underlying communicative intentions, the component defining a plurality of candidate utterances for each intention and analyzing the plurality of candidate utterances according to a Bayesian network model, the model is determined over different instances of time to probabilistically infer a communicators intent, and the component concurrently employing at least two of the communications in determining an action to facilitate achieving the intention; and
a second component to perform the action if the underlying communicative intention is above a confidence threshold.

21. A method to determine communicative uncertainty, comprising:
-
inferring a probability that a user desires a service;
performing a cost-benefit analysis to determine whether a dialog with the user is above a predetermined expected utility; and
engaging a user with a question about the desires of the service according to the expected utility. - View Dependent Claims (22, 23, 24, 25)
