Abstract

The invention provides a weighted PageRank algorithm-based method and system for quantifying drug attributes of prescriptions, which helps to improve the accuracy of PR values ​​of drug attributes. The method includes: decomposing the drug attributes of each drug in the prescription, determining the drug attributes of the prescription and the weights of the drug attributes; using the drug attributes in the prescription as drug attribute nodes in the network link structure, and according to different drug attributes According to the interaction between the drug attribute nodes, the network link structure diagram between the drug attribute nodes is constructed; according to the determined weight of the drug attribute, the weighted PageRank algorithm is used to iterate the drug attribute nodes to determine the PR value of the drug attribute. The invention is applicable to the technical field of medicine attribute quantification.

Description

technical field [0001] The invention relates to the technical field of drug attribute quantification, in particular to a method and system for quantifying drug attributes of prescriptions based on a weighted PageRank algorithm. Background technique [0002] Prescriptions are made up of a variety of medicines, and each medicine has corresponding medicine properties, such as the medicine's four natures and five flavors, meridian distribution, efficacy and other properties. The effect of TCM prescriptions is produced by the interaction of various drugs or drug properties in the prescription. In order to reflect which drug in the prescription has the greatest effect on the effect of the other drug, it is necessary to quantify the effect of each drug, and then use the drug quantification results to quantify the drug. The properties of drugs can reflect the importance of different drug properties in the prescription. In actual prescription drugs, what is often given is the actual...
