Problems solved by technology

[0003] As the amount of data increases, when traditional association rule mining algorithms, such as FP-growth algorithm, process massive medical data, the processing efficiency will be low or even impossible due to memory problems; at the same time, there are a large amount of historical data in traditional data storage media It needs to be migrated to the new storage system after the upgrade, and the efficiency of writing through the HBase application program interface is relatively low, which will squeeze the resources such as memory and CPU for system read operations

Embodiment Construction

[0052] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] By using a MapReduce-based data batch import algorithm, the hospital background data is imported into the database in batches, and at the same time, a data extraction algorithm is used to extract the characteristic data in the hospital background data at different time granularities. During the data retrieval process, according to the query The time range of the data, retrieves and ranges the characteristic data of the corresponding time granularity, greatly improves the efficiency of data retrieval, and finally uses an improved pruning FP-growth algorithm to mine the association rules between the hospital background data, providing doctors with Medical decision-making reference. refer to figure 1 As shown, it is a schematic diagram of a processing method for hospital background data provided by an embodiment ...

Abstract

The invention relates to the technical field of data processing, and discloses a hospital background data processing method, which comprises the steps of obtaining hospital background data, and importing the hospital background data into an HBase in batches by utilizing a data batch import algorithm based on MapReduce; extracting feature data of hospital background data in the HBase at different time granularities by utilizing a data extraction algorithm, and storing the feature data into a redundant data table; constructing a hospital background data tree from the feature data in the redundant data table; carrying out pruning on the hospital background data tree by utilizing an improved FPGrowth algorithm; and mining a frequent item set in the pruned hospital background data tree, and taking the frequent item set as a medical decision reference. The invention further provides a hospital background data processing system. According to the invention, medical data processing is realized.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and system for processing background data of a hospital. Background technique [0002] With the increasing maturity of information technology in the medical field, while continuously improving the level of diagnosis and improving the quality of medical services, a large amount of medical data with different structures has also shown an exponential growth, which also makes the processing of medical big data an important task at present. research hotspot. [0003] As the amount of data increases, when traditional association rule mining algorithms, such as FP-growth algorithm, process massive medical data, the processing efficiency will be low or even impossible due to memory problems; at the same time, there are a large amount of historical data in traditional data storage media It needs to be migrated to the new storage system after the upgrade. The efficiency o...
