Knowledge expression method, device and system for medical information system

Abstract

The invention discloses a knowledge expression method, device and system oriented to a medical information system. The method comprises the following steps: acquiring multiple paths of data sources related to medical data; performing data core description on the multi-path data source to obtain each group of standard data elements of the multi-path data source; performing keyword recognition processing on the multi-path data source, and extracting a plurality of keywords from the multi-path data source; obtaining each domain factor corresponding to each keyword based on the standard data element; performing knowledge extraction by utilizing each keyword and each domain factor to obtain entity knowledge and relational knowledge; according to the relationship between the entity knowledge, performing knowledge combination on the entity knowledge and the relationship knowledge to generate a knowledge graph of the medical data; and performing knowledge reasoning on the knowledge graph to obtain a knowledge reasoning result. By adopting the embodiment of the invention, the data standard of the medical information system is standardized, and the unification of the standard of the medical information system and the association of the system can be ensured.

Description

technical field [0001] The invention relates to the technical field of medical data processing, and in particular, to a knowledge expression method, device and system oriented to a medical information system. Background technique [0002] With the rapid development of medical informatization, a large amount of medical data is generated by medical institutions and various Internet platforms. These medical data contain rich medical knowledge. The medical data after data cleaning and analysis can not only provide auxiliary decision-making for doctors' clinical diagnosis It can also provide the public with high-quality medical information services and improve the public's medical information literacy. Therefore, how to dig deep and utilize medical data has become a hot spot of current people's attention. [0003] However, the current medical information system still has problems such as a wide range of data sources, insufficient data standards, and sparse data information, resu...

AI Technical Summary

Problems solved by technology

[0003] However, the medical information system at this stage still has problems such as extensive data sources, insufficient data standards, and sparse data information, resulting in low accuracy of knowledge extraction, which seriously hinders the development, association and application of medical information systems, and is not conducive to medical treatment. Standardization of information systems and interaction effects with other systems
