Natural language information processing method and device for human-computer interaction

The invention relates to a natural language information processing method and device for human-computer interaction, and the method comprises the steps: carrying out the field classification of a session text corresponding to a session voice inputted by a user in a human-computer interaction scene through a field classification sub-model in a natural language text processing model, and obtaining the field information of the session text; determining task type information of the session text based on the session progress of human-computer interaction; inputting the session text, the field information and the task type information into a task processing sub-model included in a natural language text processing model; and executing the natural language processing task indicated by the task type information based on the input data through the task processing sub-model to obtain a natural language processing result. According to the method, the NLU task and the NLG task in the man-machine interaction scene can be w
