The invention discloses a semi-structured text multilevel information retrieval method, and belongs to the field of information retrieval and data mining. According to the method, firstly, semi-structured text data is analyzed, a filtering index is constructed for structured metadata, and a semantic vector index and a keyword index are constructed for unstructured text content in parallel; during retrieval, firstly, rapid coarse screening is carried out by utilizing structured conditions so as to reduce the range; then semantic retrieval and keyword retrieval are executed in parallel in the candidate set, and a semantic correlation score and a keyword matching score are obtained respectively; and then carrying out weighted fusion on the two types of scores through a dynamic fusion layer, wherein weight parameters can be dynamically called according to a user identifier or a query scene. According to the method, the balance of retrieval efficiency and precision is realized, the problem of static stiffness of the traditional mixed retrieval weight is solved, the retrieval strategy can be adaptively adjusted according to implicit feedback of the user, and the personalized intelligent level of a retrieval system is improved.
