[0056] A best embodiment is given below:

[0057] like Figure 1 As shown, a pre-diagnosis method in this embodiment has the following steps:

[0058] S1. Construction of medical knowledge graph;

[0059] Features include:

[0060] S1-1. Data cleaning: Collect and organize comprehensive medical knowledge, including but not limited to disease symptoms, diagnostic criteria, treatment methods, drug information, medical examinations, etc. Then, clean the collected data to remove redundant and contradictory information.

[0061] S1-2, knowledge ablation and verification, use machine learning technology to integrate and verify medical knowledge, eliminate duplicate and contradictory information, ensure the accuracy and completeness of the knowledge graph, and provide a solid medical foundation for subsequent steps.

[0062] S1-3. Knowledge graph construction: select or develop knowledge graph construction tools suitable for the medical field (such as Neo4j, Dgraph, etc.), and use the knowledge graph construction tools to construct a structured medical knowledge graph based on this knowledge. The nodes in the graph represent medical entities (such as diseases, symptoms, drugs, etc.), and the edges represent the relationships between entities (such as causal relationships, therapeutic relationships, etc.).

[0063] The key to this step is to ensure the accuracy and completeness of the knowledge graph and provide a solid medical foundation for subsequent steps.

[0064] S2, model training;

[0065] Further including:

[0066] S2-1, data preprocessing;

[0067] Prepare training data, including a large number of real doctor-patient conversation records and corresponding medical diagnosis results, and pre-process the doctor-patient conversation records, including noise removal, word segmentation, part-of-speech tagging, etc.

[0068] S2-2, model training and optimization;

[0069] Based on deep learning technology, train a large model that can understand and process natural language (such as BERT, GPT, etc.). The model must be able to extract key information from the patient's complaints and generate targeted inquiries based on the knowledge in the knowledge graph. The training data should include a large number of real doctor-patient conversation records and corresponding medical diagnosis results to ensure that the model can accurately understand the patient's intentions and give reasonable inquiries.

[0070] S2-3, multi-round dialogue capability;

[0071] The trained model has the ability to conduct multiple rounds of conversations, can dynamically adjust subsequent inquiries based on the patient's answers, and introduce semantic understanding technology to improve the model's ability to analyze key symptoms and information.

[0072] S3, patient information collection;

[0073] Specifically include:

[0074] S3-1. Chief complaint inquiry and extraction;

[0075] The patient describes his / her main complaint through the interface input or voice, and the system uses the trained large model to analyze the main complaint and extract key symptoms and information. The purpose of this step is to quickly identify the patient's main health problem and provide direction for subsequent inquiries.

[0076] S3-2, key information retrieval;

[0077] Based on the chief complaint, relevant information is retrieved from the knowledge graph, including common symptoms, necessary examinations, medicines, and other information.

[0078] S3-3, large model intelligent inquiry of current medical history;

[0079] Based on the information extracted from the chief complaint, the big model intelligently generates a series of questions about the current medical history related to the current symptoms, such as the duration of symptoms, frequency of attacks, aggravating or alleviating factors, etc. These questions are designed to gain a deeper understanding of the patient's current health status and provide more clues for diagnosis.

[0080] S3-4, large model intelligent inquiry of past history;

[0081] Based on the current medical history, the big model further asks the patient about his past medical history, including past illnesses, surgeries, hospitalizations, allergies, etc. This information helps identify potential health risks and may affect the treatment of current diseases.

[0082] S3-5, large model intelligent inquiry of personal history;

[0083] Personal history inquiries include lifestyle habits (such as smoking, drinking), eating habits, occupational exposure, family medical history, etc. These factors may be directly related to the patient's health status and are crucial for assessing disease risks and formulating preventive measures.

[0084] S3-6, large model intelligent inquiry of family history;

[0085] The large model asks whether there are people with similar symptoms in the patient's family, and whether there is specific information about the family's history of infectious diseases and genetic diseases, such as the severity of the illness and treatment status of the sick relatives.

[0086] In addition, the big model will intelligently recommend genetic counseling or screening that patients may need based on the information in the medical vector knowledge base. Such in-depth inquiries help to gain a more comprehensive understanding of the patient's family health status and provide patients with more accurate diagnosis and treatment recommendations.
