In this embodiment, the subclasses are divided into one or more subclasses, and the subclasses are divided into one or more minimum classes.
It can be seen that the product classification code is divided into five layers. The first layer code is a product property classification code, and the value of the first layer code is fixed as Z to represent the Chinese patent medicine; the first class classification code of the representative product of the second layer code corresponds to the major class, and the value range of the first class classification code is A-V; the secondary classification code of the representative product of the third layer code corresponds to the subclass and has a value range of 0-99; the third class code of the representative product of the fourth layer code corresponds to the subclass, and the value range is A-Z or 0, and the blank time is 0; the representative product four-level classification code of the fifth layer code corresponds to the minimum class, and the value range is 0-9, and the blank time is 0.
In one embodiment, the codes corresponding to each of the major and minor classes are shown in table 2.
TABLE 2
Further, the step S3 specifically includes: step S31, setting a definition range of the Chinese patent medicine; step S32, acquiring all data of the data table; and step S33, extracting data in the data table according to the definition range of the Chinese patent medicine as the sampling data.
Wherein, the definition range of the Chinese patent medicine comprises five types, wherein,
the first type is that all medicines with the approval clerical number of the national medicine standard Z.
The second type is that of the imported drugs, the chinese drugs in the asian countries or regions are similar to those of the traditional Chinese drugs belonging to the first type.
The third type is that the approval document is the national drug standard H and other dosage forms with the same component belong to the first type of drugs. For example, if the approval document of puerarin injection is national standard character H and the approval document of puerarin tablet belonging to other dosage forms of puerarin injection is national standard character Z, the puerarin injection meets the definition range of the third type; in addition, the approved document of the imported ginkgo leaf preparation is national standard character H, and the approved document of the domestic ginkgo leaf preparation is national standard character Z, so that the imported ginkgo leaf preparation also accords with the definition range of the third type.
The fourth type is a medicine with approval document number of national medicine standard H and main component and domestic Chinese patent medicines for treating the same disease clinically. For example, the approval document of silymarin capsule is national medicine standard H, the main component thereof is silymarin, and the approval document of Yiganling tablet containing 77mg silymarin is national medicine standard Z, then silymarin capsule conforms to the definition range of the fourth type.
The fifth type is to extract medicines containing various uncertain effective ingredients from natural plants, such as galutes extract tablet.
The application solves the problem of data omission caused by fuzzy definition of part of Chinese patent medicines in the classification process by accurately dividing the definition range of the Chinese patent medicines by combining approval paper numbers, clinical application and medicine components and extracting sampling data according to the definition range.
Further, the step S4 specifically includes:
and step S41, performing data processing on the sampling data. The data processing comprises data specification processing, experience value processing, data amplification processing and data overall checking. Wherein, the data normalization process is to convert the data into a certain standard form so as to facilitate the subsequent processing and analysis. Common data normalization methods include min-max normalization, z-score normalization, decimal scale normalization, and the like. The data normalization processing can eliminate the dimension influence in the data, so that different indexes have comparability, and the accuracy and the interpretability of the data are improved. Empirical value processing refers to processing and modifying data using expert experience or domain knowledge. Experience value processing is commonly used for data missing and outlier processing, missing data can be filled in by means of average value, median, mode and the like, and outliers can be identified and removed by means of box diagram and the like. The data amplification processing means that the sample capacity is increased by transforming and expanding the original data, thereby improving the reliability and generalization capability of the data. Common data amplification methods include upsampling, downsampling, interpolation, balanced sampling, and the like. The data amplification treatment can effectively reduce the risk of overfitting and improve the generalization capability of the model. By the data processing means, the quality and the reliability of data can be improved, so that the effects of subsequent analysis and modeling are improved.
S42, analyzing the sampling data by referring to the Chinese patent medicine classification standard to obtain an analysis result; wherein, the analysis result at least comprises indication, main function, main component, approval document, specification, dosage form, production enterprises and clinical application information of the Chinese patent medicine. In addition, the analysis results include the drug common name, administration route, unit price, quantity, amount, amplified quantity, and amplified amount.
And step S43, matching product classification codes according to the analysis result.
Further, before step S1, the classification method of the present application further includes: the Chinese patent medicine data are arranged into a data table and stored into a Chinese patent medicine database, and metadata of the Chinese patent medicine database are generated at the same time. Specifically, in the process of arranging the data of the Chinese patent medicine into a data table, a table is firstly generated, and the table is provided with a unified table head, hospital codes and the fid of the Chinese patent medicine, wherein the fid represents the unique code of each medicine; and then checking total data, including checking whether the count data is complete, whether the count form is consistent with the past and whether the count number is similar to the past, wherein the count data comprises the following fields: medicine name, manufacturer, specification, quantity, and stock.
Further, in order to facilitate statistics and classification of data by the chinese patent drug database operator, metadata of the chinese patent drug database includes a table name of each data table and description information of data, and a field name, a field type, and data length accuracy limitation information of each field in each data table. According to the method, metadata can provide comprehensive description and description of data and objects in the Chinese patent medicine database, and convenience is brought to Chinese patent medicine database administrators and developers to manage and maintain the Chinese patent medicine database. Further, step S2 is specifically to obtain a data table in a database of the Chinese patent medicine according to the metadata. By utilizing the metadata, the data and the objects in the Chinese patent medicine database can be quickly searched, the structure and the attribute of the data and the objects and the relation among the data and the objects can be known, and therefore the data and the objects in the Chinese patent medicine database can be better understood and used.
The foregoing is merely illustrative and explanatory of the application, as it is well within the scope of the application as claimed, as it relates to various modifications, additions and substitutions for those skilled in the art, without departing from the inventive concept and without departing from the scope of the application as defined in the accompanying claims.
