System and method for using semantic and syntactic graphs for utterance classification |
摘要 |
Disclosed herein is a system, method and computer readable medium storing instructions related to semantic and syntactic information in a language understanding system. The method embodiment of the invention is a method for classifying utterances during a natural language dialog between a human and a computing device. The method comprises receiving a user utterance; generating a semantic and syntactic graph associated with the received utterance, extracting all n-grams as features from the generated semantic and syntactic graph and classifying the utterance. Classifying the utterance may be performed any number of ways such as using the extracted n-grams, a syntactic and semantic graphs or writing rules. |

1. A method comprising:
generating, via a processor, a semantic and syntactic graph associated with a first call type; converting the semantic and syntactic graph into a first finite state transducer; composing the first finite state transducer with a second finite state transducer to form a third finite state transducer, wherein the second finite state transducer comprises all possible n-grams, and wherein the third finite state transducer comprises a subset of the all-possible n-grams; extracting the subset of the all-possible n-grams as features from the third finite state transducer, to yield extracted n-grams; associating an utterance with a second call type based on the extracted n-grams, to yield a classified utterance, wherein the second call type is determined based on semantic and syntactic features in the extracted n-grams; and responding to a user in a natural language dialog based on the classified utterance. |
