Automatic generation method and system for purchase technical specification book

The invention discloses an automatic generation method and system for a purchase technical specification book. The method comprises the following steps: acquiring a data set, and preprocessing the data set; dividing the preprocessed data set into a training set and a verification set; performing multiple rounds of training on the training set through a pre-training language model, and performing fine tuning on the model through the verification set to obtain a final document error correction model; training the training set through the original sensitive word recognition model, and finely adjusting the model through the verification set to obtain a final sensitive word recognition model; carrying out error detection on a to-be-detected data set through the final document error correction model and carrying out first correction; and performing sensitive word recognition on the data set after the first correction through a final sensitive word recognition model, performing second correction, and outputting the
