Display device and grammar verification method

Some embodiments of the invention provide a display device and a grammar verification method, the method can respond to a text instruction input by a user, parse a target text of the text instruction, and input the target text to a multi-language model. Wherein the multi-language model is a model obtained by finely adjusting an initial model through a grammar detection task, the initial model is a model obtained based on label-free text data pre-training, the pre-training process of the initial model comprises multi-task learning and cross-language representation learning, the multi-task learning comprises at least two types of language classifications, and the cross-language representation learning comprises at least two types of language classifications. Different grammar detection tasks are set for different language classifications. And detecting a target grammar structure of the target text through the multi-language model, outputting a detection result of the target text according to the target grammar
