Problems solved by technology

[0005] In the prior art, the same structured extraction software is usually used to extract structured information from texts in different fields, and because the structured information extracted from texts in different fields will be different due to the different fields of the text, so now When existing technologies extract structured information in texts in different fields, the accuracy of extraction is low

Abstract

The invention provides a method and device for extracting structured information, equipment and a computer storage medium, and the method comprises the steps: obtaining a to-be-processed text input bya user, and determining the field of the to-be-processed text; determining an information extraction model corresponding to the field of the to-be-processed text, wherein the determined information extraction model is one of a reading understanding model, a sequence labeling model and a sequence generation model; and taking the to-be-processed text as input, inputting the to-be-processed text into the determined information extraction model, and taking an output result of the determined information extraction model as structured information of the to-be-processed text. According to the invention, the extraction accuracy of the structured information can be improved.

Description

[0001] 【Technical field】 [0002] The present invention relates to the technical field of natural language processing, in particular to a method, device, device and computer storage medium for extracting structured information. [0003] 【Background technique】 [0004] In various fields, texts recorded in natural language are ubiquitous. We define such texts as unstructured texts, such as financial reports, news, medical records, etc. At the same time, in various fields, there is also a general need to extract structured information. That is to extract some structured attribute values ​​from the unstructured text, such as extracting the company name from the financial report, extracting the location of the attack from the news, extracting the cancer stage of the patient from the medical record, etc. However, due to the existence of a large number of unstructured texts, it is difficult to directly carry out structured extraction work by manpower, so computer-based structured ex...
