Text feature-based information extraction method and apparatus, and electronic device

The invention discloses an information extraction method and device based on text features and electronic equipment, and the method comprises the steps: carrying out the pre-training coding of a to-be-processed information text based on a pre-training model, and generating the text features; respectively inputting the text features into a pre-constructed universal domain feature extractor and a pre-constructed private domain feature extractor; a universal domain feature extractor and a private domain feature extractor are obtained respectively, the universal domain feature is output of the universal domain feature extractor, and the private domain feature is output of the private domain feature extractor; and coupling the universal domain features and the private domain features, inputting a coupling result into a hybrid expert predictor for decoding, generating a corresponding information label, and completing an information extraction operation. According to the embodiment of the invention, decoding is carr
