Method for Automated Sentence Planning in a Task Classification System

A spoken dialog system, the spoken dialog system comprising:

• a processor;
• a first module configured to control the processor to receive a single input communication from a user in the spoken dialog system;
• a second module configured to control the processor to generate, in response to the single input communication, a plurality of communication goals, wherein the plurality of communication goals are ranked by a priority;
• a third module configured to control the processor to generate a plurality of sentence plans corresponding to the plurality of communication goals, wherein each sentence plan of the plurality of sentence plans comprises elementary speech acts and is a viable and potentially usable prompt in response to the single input communication;
• and
• a fourth module configured to control the processor to present to the user a selected sentence plan from the plurality of sentence plans as a response to the single input communication.

A non-transitory computer-readable medium storing a computer program having instructions which when executed by a processor control the processor, the instructions comprising:

• receiving a single input communication from a user in a spoken dialog system;
• generating, via a processor and in response to the single input communication, a plurality of communication goals, wherein the plurality of communication goals are ranked by a priority;
• generating a plurality of sentence plans corresponding to the plurality of communication goals, wherein each sentence plan of the plurality of sentence plans comprises elementary speech acts and is a viable and potentially usable prompt in response to the single input communication;
• and
• presenting to the user a selected sentence plan from the plurality of sentence plans as a response to the single input communication.
