Abstract: In the natural language understanding module,there are two tasks of intent detection and slot filling,and there is a strong correlation between the two tasks that the generation of slot information is highly dependent on the intent information.However,most of the existing works regard it as two independent tasks to achieve,resulting in that the accuracy of the dialogue system cannot be further improved.To this end,aiming at the correlation information between the intent detection task and the slot filling task in the dialogue system,on the basis of the existing work,an end-to-end network model based on the idea of  Stack-Propagation was proposed.The idea of the Stack-Propagation framework in the decoder stage was borrowed and improved,which added the result of intent detection to the input of the slot filling task,and used the result of the intent detection to further guide the slot filling task.Through experiments on SMD dataset,it was proved that the model could not only make full use of the correlation information between the intent detection task and the slot filling task,but also achieve the effect of mutual promotion through joint learning,and finally effectively improve the accuracy of the dialogue system.
