Problems solved by technology

Traditional neural network-based self-adaptive techniques often completely share information in the source domain by designing a mapping to the target domain, but this assumes that the shared information is all valid, ignoring the information that may exist that is not conducive to training.

Abstract

The invention discloses a joint modeling method for a spoken language understanding model and a language model, which comprises the steps of sampling a text sequence from a sample library, and transforming the text sequence into a corresponding training vector sequence; inputting the training vector sequence into a bidirectional long-short term memory network; performing joint training of the spoken language understanding model and the language model by adopting network output of the bidirectional long-short term memory network; and extracting text feature information from the training vectorsequence by adopting the bidirectional long-short term memory network for joint training of the spoken language understanding model and the language model, thereby realizing the sharing of semantic and grammatical feature information between the spoken language understanding model and the language model.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a joint modeling method for spoken language comprehension and language model, a dialogue method and a system. Background technique [0002] The traditional spoken language understanding system (Spoken Language Understanding System) and the automatic speech recognition system (Automatic Speech Recognition System) are relatively independent, and the semantic analysis is based on the 1-best recognition result solved by the language model (Language Model) in the speech recognition system. [0003] With the enhancement of computing power and the development of neural networks, multi-task joint modeling can train the network more efficiently, and can also improve the performance of each task by designing the network. Spoken language comprehension and language model have the same model input (text), and joint modeling shares semantic and grammatical information w...
