Natural language processing model training method, natural language processing model training device, application question correcting method and application question correcting device

The embodiment of the invention provides a natural language processing model training method, a natural language processing model training device and an application question correcting method and device. The natural language processing model training method comprises the steps of obtaining a prompt text, an application question text, an answer text, a reference answer text and answer description information corresponding to a sample application question; based on the prompt text, the application question text, the answer text, the reference answer text and the answer description information, constructing a sample text sequence corresponding to the sample application question; inputting the sample text sequence into an initial natural language processing model for predicting filling information corresponding to the information position of the answer description information in the sample text sequence to obtain predicted answer description information; and performing parameter adjustment on the initial natural
