Text classification and recognition system and method

The invention discloses a text classification and recognition system and method. The method comprises the steps that a preprocessing unit preprocesses multiple pieces of original data to obtain multiple pieces of preprocessed data; the model adjustment unit adds a linear classifier into the pre-training model to form an adjustment model, optimizes and adjusts weight parameters and hyper-parameters in the adjustment model according to a plurality of pieces of pre-processed data until the prediction accuracy of the adjustment model is not lower than an accuracy threshold, and outputs the adjustment model at the moment as an optimization model; the correction unit corrects the text category output by the optimization model according to a correction rule to obtain correction model output; and the text recognition unit inputs each piece of text data into the correction model to obtain a plurality of text categories, and controls and perfects the Chinese word segmentation component to carry out entity recognition o
