Abstract

The invention discloses a structured information generation method and device, electronic equipment and a storage medium, and relates to the field of information processing in the field of natural language processing. According to the specific implementation scheme, the method includes: obtaining a source text sequence; inputting the source text sequence into a behavior-evaluation model so as to generate structured information corresponding to the source text sequence, wherein the behavior-evaluation model comprises a behavior sub-model and an evaluation sub-model, the behavior sub-model is used for generating the structured information corresponding to the source text sequence according to the input source text sequence, and the evaluation sub-model is used for training the behavior sub-model. Therefore, the corresponding structured information is directly generated through the behavior-evaluation model according to the input source text sequence, end-to-end information extraction isrealized, the technical problem of high training model labeling cost during open field information extraction is solved, and the structured information extraction efficiency and accuracy are effectively improved.

Description

technical field [0001] The present application relates to the field of information processing in the field of natural language processing, and in particular to a method, device, electronic device and storage medium for generating structured information. Background technique [0002] In various industries, texts recorded in natural language are ubiquitous, and such texts are usually defined as unstructured texts, such as financial statements, news, medical records, and so on. At present, there is a demand for structured information extraction in application scenarios such as public opinion analysis, communication analysis, and data platform services, that is, extracting required structured fields from unstructured text, such as extracting company names from financial statements, and Extract the location of an attack from a computer, extract a patient's condition from a medical record, and more. Information extraction includes vertical domain information extraction and open d...
