Disambiguation of Requests for Digital Assistant Task Execution

A computer-implemented method comprising:

• receiving, by a disambiguation system associated with a digital assistant, an utterance from a user comprising an intent, the intent defining a task executable by the digital assistant in response to the utterance;
• transmitting, by the disambiguation system, the utterance to a natural language processing system;
• receiving, by the disambiguation system, a plurality of predicted intents and a plurality of slot values determined by the natural language processing system based on the utterance, the plurality of predicted intents defining tasks executable by the digital assistant and the plurality of slot values providing information usable by the digital assistant to execute the tasks;
• determining, based on a hierarchy model associated with the disambiguation system, at least one common ancestor for the plurality of predicted intents;
• and
• generating, by the disambiguation system, a response for transmission to the user using the plurality of predicted intents, the plurality of slot values, and the at least one common ancestor, the response usable by the digital assistant to determine the intent.

A non-transitory computer-readable medium comprising instructions that are executable by a processing device for causing the processing device to perform operations comprising:

• receiving, by a disambiguation system associated with a digital assistant, an utterance from a user comprising an intent, the intent defining a task executable by the digital assistant in response to the utterance;
• transmitting, by the disambiguation system, the utterance to a natural language processing system;
• receiving, by the disambiguation system, a plurality of predicted intents and a plurality of slot values determined by the natural language processing system based on the utterance, the plurality of predicted intents defining tasks executable by the digital assistant and the plurality of slot values providing information usable by the digital assistant to execute the tasks;
• determining, based on a hierarchy model associated with the disambiguation system, at least one common ancestor for the plurality of predicted intents;
• and
• generating, by the disambiguation system, a response for display to the user using the plurality of predicted intents, the plurality of slot values, and the at least one common ancestor, the response usable by the digital assistant to determine the intent.
