Abstract:
1. A computer method for converting an utterance representation into a response, the computer method comprising the steps of: generating an application specific goal derived from the utterance representation, wherein the application specific goal and the utterance representation are propositions comprising attribute-object-value triples, the proposition corresponding to the utterance representation being derived from a frame representation; analyzing the utterance representation based on the application specific goal and a corresponding set of goal-directed rules to identify ambiguous information in the utterance representation or to generate a subgoal, each goal-directed rule representing a valid inference step from the goal-directed rule's condition to the application specific goal that may be taken in a domain associated with the application specific goal; generating a response based on the analysis of the utterance representation if ambiguous information is identified; and wherein the response is a computer application program command based on the utterance representation.
