Abstract

A natural language understanding (NLU) system used in a dialogue systems comprises a first-level NLU sub-system and at least one second-level NLU sub-system. Each second-level NLU sub-system is communicatively coupled with, and has a relatively higher performance than, the first-level NLU sub-system. The first-level NLU sub-system performs a first calculation over an input text received, and then outputs a first meaning if the first meaning is generated with a first confidence level surpassing a first threshold or passes on the input text to one second-level NLU sub-system based on a pre-determined rule if otherwise. Each second-level NLU sub-system receives the input text from the first-level NLU sub-system, and performs a second calculation over the input text, and then outputs a second meaning if the second meaning is generated with a second confidence level surpassing a second threshold or outputs a result indicating a rejection of meaning if otherwise.

Claims22

Dependent claims

A natural language understanding (NLU) system for determining a meaning of an input text, comprising:

a first-level NLU sub-system, configured to receive the input text;
and
at least one second-level NLU sub-system, each communicatively coupled with, and having a relatively higher performance than, the first-level NLU sub-system;
wherein:
the first-level NLU sub-system is configured, upon receiving the input text, to perform a first calculation over the input text, and then:
if the first calculation generates a first meaning corresponding to the input text with a first confidence level surpassing a first threshold, to output the first meaning;
or
if otherwise, to pass on the input text to one of the at least one second-level NLU sub-system based on a pre-determined rule;
and
each of the at least one second-level NLU sub-system is configured, upon receiving the input text from the first-level NLU sub-system, to perform a second calculation over the input text, and then:
if the second calculation generates a second meaning corresponding to the input text with a second confidence level surpassing a second threshold, to output the second meaning;
or
if otherwise, to output a result indicating a rejection of meaning.
