Embodiment 1
[0031] Whether it is based on feature engineering or deep learning, prior knowledge is rarely used in existing research work, and prior knowledge is of great help to computers to better understand the semantics of sentences, especially in specific In the medical field, the use of knowledge graphs in professional fields is of great help in calculating the similarity of medical texts.
[0032] Based on this, in one or more implementations, a method for searching similar medical records based on deep learning is disclosed, such as figure 1 shown, including the following steps:
[0033] Step (1): Construct a knowledge graph in the medical field through the knowledge graph construction technology, where the entities in the knowledge graph represent medical concepts, and the edges in the knowledge graph represent the relationship between medical concepts. Store the constructed knowledge graph in Neo4j for later use.
[0034] Specifically, the following processes are included:
[...
Embodiment 2
[0069] In one or more implementations, a similar medical record search system based on deep learning is disclosed, including:
[0070] means for building knowledge graphs capable of representing relationships between medical concepts;
[0071] A device for extracting the subject of the medical record sample information as characteristic information of the medical record after preprocessing the obtained medical record sample information, and storing it in a database;
[0072] A device for extracting medical record feature information from the input electronic medical record information; obtaining a subgraph vector containing medical common sense related to the electronic medical record in the knowledge graph;
[0073] It is used to input the characteristic information of the current medical record, the subgraph vector and the characteristic information of the medical record in the medical record information sample database into the trained neural network model, and calculate th...
Embodiment 3
[0076] In one or more embodiments, a terminal device is disclosed, including a server, the server includes a memory, a processor, and a computer program stored on the memory and operable on the processor, and the processor executes the The program realizes the search method for similar medical records based on deep learning in the first embodiment. For the sake of brevity, details are not repeated here.
