Embodiment Construction

[0073] Aiming at the problems of low precision in the existing medical entity recognition and knowledge map construction, this application proposes a solution to the information collection of knowledge maps using regular expressions, hidden Markov models, dependency parsing, and graph neural networks. , knowledge fusion problem. The combination of manual review and computer is used to solve the problems of low accuracy and unreasonable utilization of structural information. The dynamic knowledge map update and completion mechanism further ensures the completeness of the medical knowledge base.

[0074] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and not necessarily Used to describe a specific sequence or sequence. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments desc...

Abstract

The invention relates to the field of artificial intelligence, and discloses a medical knowledge graph construction method and a device, equipment and a storage medium. According to the method, a knowledge feature extraction mode is determined on the basis of a collected data source to analyze medical data in a targeted mode, so that accurate entity names are obtained, entities with different entity names but the same ontology are fused through a fusion algorithm, the entities are unified, and finally a knowledge graph is constructed on the basis of the fused entities. Therefore, the problem of low knowledge graph precision caused by non-uniform related medical knowledge entities is solved, powerful support and guarantee are provided for diagnosis means and methods in the medical field, and knowledge sharing and management can be completed more reasonably and efficiently. In addition, the invention also relates to a blockchain technology, and the medical knowledge graph and the entitycan be stored in the blockchain.

Description

technical field [0001] This application relates to the field of artificial intelligence, in particular to a method, device, equipment and storage medium for constructing a medical knowledge map. Background technique [0002] The knowledge graph is a knowledge base with a graph structure, which belongs to the category of knowledge engineering, and is also an important basic measure for the realization of artificial intelligence. The application of the knowledge map expands the connotation of the original scientific knowledge map and extends its application scenarios. [0003] However, the current application of knowledge graphs is still limited to search engines and question answering systems, and other applications are less. In the medical field, there are usually intricate relationships between illnesses, diseases, and diagnosis and treatment methods, and the data storage mode of the existing relational model is not convenient for the expansion of the content of the medica...
