System and method of spoken language understanding in human computer dialogs
First Claim
1. A method comprising:
- identifying, in a domain-independent manner, a dialog act for an independent clause of a speech recognizer output;
identifying, in a domain-dependent manner, an object within the independent clause; and
recursively generating, via a processor, for each sub-independent clause within the independent clause, a semantic representation using the dialog act and the object of the independent clause.

Abstract
A system and method are disclosed that improve automatic speech recognition in a spoken dialog system. The method comprises partitioning speech recognizer output into self-contained clauses, identifying a dialog act in each of the self-contained clauses, qualifying dialog acts by identifying a current domain object and/or a current domain action, and determining whether further qualification is possible for the current domain object and/or current domain action. If further qualification is possible, then the method comprises identifying another domain action and/or another domain object associated with the current domain object and/or current domain action, reassigning the another domain action and/or another domain object as the current domain action and/or current domain object and then recursively qualifying the new current domain action and/or current object. This process continues until nothing is left to qualify.
