Text transformation model training method and apparatus, and text transformation method and apparatus

Abstract

The invention discloses a text transformation model training method and apparatus, and a text transformation method and apparatus. One specific embodiment of the text transformation model training method includes the steps: successively inputting the characters in the input character sequence corresponding to the input text into the neural network corresponding to a text transformation model to begenerated, wherein the neural network corresponding to the text transformation model includes an encoder and a decoder; for each character in the input character sequence, based on the state of the hidden layer in the decoder after decoding of the input last character, using the encoder to code to obtain an intermediate meaning vector of the character, and using the decoder to interpret the intermediate semantic vector to obtain the prediction result of the character; and according to the difference between the prediction result of the input character sequence and the mark result corresponding to the input text, adjusting the parameters of the neural network. The text transformation model obtained through the text transformation model training method can realize combined prediction of text regularization and polyphones, thus reducing the resource maintenance cost.

Problems solved by technology

However, the generalization of the rule-based method is poor, and there are strict restrictions on the context of the text. If the text format or content changes slightly, the corresponding rules may become invalid.

Moreover, there is overlap between the resources required for text regularization processing and the resources required for polyphonic pronunciation annotation (such as the corpus required for building rules), and the maintenance cost of these resources is relatively high
