Natural language task-oriented dialog manager and method
First Claim
1. A system for conversant interaction comprising:
- a recognizer which receives and processes input information and outputs a recognized representation of the input information;
a dialog manager coupled to the recognizer, the dialog manager receives the recognized representation of the input information, the dialog manager having task-oriented forms for associating user input information therewith, the dialog manager being capable of selecting an applicable form from the task-oriented forms responsive to the input information by scoring the forms relative to each other; and
a synthesizer converts a response generated by the dialog manager to output the response.

Abstract
A system for conversant interaction includes a recognizer for receiving and processing input information and outputting a recognized representation of the input information. A dialog manager is coupled to the recognizer for receiving the recognized representation of the input information, the dialog manager having task-oriented forms for associating user input information therewith, the dialog manager being capable of selecting an applicable form from the task-oriented forms responsive to the input information by scoring the forms relative to each other. A synthesizer is employed for converting a response generated by the dialog manager to output the response. A program storage device and method are also provided.

11. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method blocks for managing dialog for speech recognition systems, the method blocks comprising:
-
assembling attributes and values in pairs based on a semantic representations of input speech;
processing semantic representations to determine a plurality of admissible forms in accordance with pairs of attributes and values;
scoring the admissible forms to determine which form is most relevant and responsive to the pairs of attributes and values and thereby being responsive to input speech; and
sending messages to be output in accordance with the input speech and the context of the input speech in accordance with the most relevant form. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
