System and Method of Determining a Domain and/or an Action Related to a Natural Language Input

摘要

The disclosure relates to methods, systems and other embodiments directed to determining an information domain match for a natural language (NL) input (e.g., a spoken utterance), and confirming whether the NL input is correctly matched to the information domain. For example, after receiving an NL input, a first information domain to which the NL input belongs and a feature value set may be determined based on a semantic pattern matching technique. Further, a second information domain to which the NL input belongs, and a corresponding confidence score related to the second information domain may be determined. The second information domain may be determined based on a first statistical classification technique. Based on the determined feature value set and the confidence score related to the second information domain, it may be confirmed whether the NL input correctly belongs to the first information domain, e.g., based on a second statistical classification technique.

主权项

1. A method to confirm whether a domain match determined for a natural language input is correct, the method being implemented on a computer system having one or more physical processors programmed with computer program instructions which, when executed, perform the method, the method comprising:
receiving, at the computer system, a natural language (NL) input; determining, by the computer system, based on a semantic pattern matching technique, a first information domain to which the NL input belongs, and a feature value set; determining, by the computer system, a second information domain to which the NL input belongs, and a corresponding confidence score related to the second information domain; and determining, by the computer system, whether the NL input correctly belongs to the first information domain based at least on the feature value set and the confidence score.
