Abstract

The present application provides a text processing method, device, electronic equipment, and storage medium, wherein the processing method includes: obtaining character feature vectors of each character in the text to be processed; character feature vectors of each character in the text to be processed The vector is input into the pre-trained text processing model, and the character category of each character output by the text processing model is obtained; wherein, the text processing model is obtained by using the perturbation sample text training of adding random feature vectors; based on the A character category of each character in the text to be processed, extracting multiple entities from the text to be processed, and determining the entity category of each entity. In this application, the text processing model is trained by using the disturbed sample text with random feature vectors added, which improves the stability of the text processing model. When there is interference, the accuracy of the character category output by the entity extraction model is high, thereby improving the recognition Entity and entity category accuracy.

Description

technical field [0001] The present application relates to the technical field of natural language processing, and in particular, relates to a text processing method, device, electronic equipment, and storage medium. Background technique [0002] In the field of natural language processing technology, entities represent specific things, individual subjects, supporters of phenomena, etc., such as names, organizations, etc., in the process of text processing, because entities can represent various objects in the text, therefore, The main content of the text can be determined by identifying entities in the text. [0003] At this stage, open source entity extraction models are usually used to identify entities in text, such as the CRF model, but the existing entity extraction models have poor anti-interference ability. In the presence of interference, the entities identified by the entity extraction model Accuracy is low. Contents of the invention [0004] In view of this, th...
