icd-11 coding retrieval method based on natural semantic processing and knowledge graph

Abstract

The present disclosure provides an ICD-11 coding retrieval method based on natural semantic processing and knowledge graph, which obtains freely written clinical diagnosis text data; performs natural language processing on the obtained text data, obtains entity and entity relationship recognition results, and marks them out. Entity and the entity type to which it belongs; mark other entities directly linked to the entity on the medical knowledge graph, record the relationship weight coefficient; combine the entity relationship and relationship weight coefficient on the medical knowledge graph, through the standard diagnosis of the entity and entity relationship tree structure Searching for candidate codes; retrieving and screening the combinations of candidate codes according to ICD-11 coding rules, and selecting the most reasonable combination codes as the ICD-11 diagnostic codes; the present disclosure realizes the intelligence of the retrieval of the ICD-11 diagnostic codes, and solves the problem of There are no coders or insufficient coders in medical institutions, which reduces labor costs and communication costs.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, in particular to an ICD-11 code retrieval method based on natural semantic processing and knowledge graph. Background technique [0002] The statements in this section merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] The International Classification of Diseases (ICD), as an international classification standard for diseases and related health problems, is an important part of the health information standard system. It has been more than 100 years since its inception, and it has undergone several revisions during this period, from initially only used for statistics on causes of death, to a statistical classification involving all diseases and causes of death, including injuries and poisoning and their external causes. Disease classification is to classify diseases according to certain characteristics according to ce...

[0006] But the inventor finds that the retrieval of ICD codes can only be retrieved by keywords or pinyin brevity codes at present. For ICD-11, only the codes of each part in the diagnosis can be retrieved, and then combined together, which is inconvenient to use and Inaccurate; on the one hand, due to the incompatibility between clinical terms and ICD-11 standard diagnostic coding terms, on the other hand, the retrieval of each part is very cumbersome for clinicians and coders, and a diagnosis needs to be searched many times to obtain Combines an encoded result and is prone to wrong combinations
