[Abstract]:The accurate query of medical database resource characteristic information can effectively improve the quality of medical information query. For the accurate query of feature information, it is necessary to normalize the feature data information, calculate the similarity coefficient of different feature data, and complete the query of resource feature information. The traditional method firstly establishes the objective function of information query and optimizes the objective function, but neglects to calculate the similarity coefficient of different characteristic data, which leads to the low precision of the query result. An accurate query method of resource feature information based on fuzzy clustering analysis is proposed. This method combines feature theory to construct multi-level vector auto-regression space of database information vector, constructs database query function by feature reasoning method of subtraction clustering, and normalizes feature data information. The similarity coefficients of different feature data are calculated, the statistics of sample values close to each other are described, the average vectors of all sample vectors in clustering are given, and the accurate query method of resource feature information under fuzzy clustering analysis is completed. The experimental results show that the proposed method has high query accuracy and lays a foundation for improving the quality of medical information query.
