This invention relates to the field of information retrieval technology, specifically to a retrieval enhancement generation method based on machine learning for second-level retrieval of user data. This method solves the technical problems in existing technologies where structured medical data suffers severe loss of key clinical semantics during vectorization and fixed-length segmentation, and cannot support cross-indicator correlation analysis and low-latency feedback. The method includes: acquiring user queries against a structured user database; determining the semantic loss of at least one candidate data segment corresponding to the user query in the temporal continuity and medical relevance dimensions; using the semantic loss to characterize the degree of clinical semantic loss caused by segmentation of the candidate data segment; determining the completeness of the indicator association between the candidate data segment and the user query based on the semantic loss; and adjusting the retrieval results for the user query based on the indicator association completeness.
