Problems solved by technology

However, because the data stored in the database has many characteristics and a large amount, such a data mining method requires a large amount of calculations such as keyword search and matching or a large amount of data analysis, which is inefficient and requires high computing equipment; On the one hand, the results of data mining depend to a certain extent on the keywords and parameters configured by the operator, as well as the experience of the operator, which has a certain degree of subjectivity, making the results of data mining inaccurate.

Embodiment Construction

[0052] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0053] The flowchart of an embodiment of the database user data processing method of the present invention is as follows figure 1 shown.

[0054] In step 101, a plurality of predetermined characteristics of user data in a database are selected. The predetermined features may include forward features and reverse features. Positive features refer to features that play a positive role in user evaluation. The larger the positive feature data, the higher the user evaluation; the reverse feature refers to the features that play a negative role in user evaluation. The smaller the reverse feature data, the higher the user evaluation.

[0055] In step 102, normalization data of predetermined features are acquired according to the data of predetermined features. The forward data includes the data of forward features and the d...

Abstract

The invention provides a method and device for processing user data in a database and relates to the field of data mining. The method for processing user data in the database comprises the following steps: selecting a plurality of reserved characteristics in the user data, wherein the reserved characteristics include forward characteristics and backward characteristics; acquiring the forward data according to the data of the reserved characteristics; standardizing the forward data of the reserved characteristics and acquiring the standardized data; confirming a user ranking parameter on the basis of the standardized data of the reserved characteristics according to the weights of the reserved characteristics; and ranking the users according to the user ranking parameter, thereby acquiring a user ranking table. According to the method, the data of the reserved characteristics of the user can be operated on the basis of the weights corresponding to the reserved characteristics, so as to generate the user ranking parameter and rank according to the magnitude of the user ranking parameter. Such a data processing mode is small in operand and high in efficiency and the users can be more objectively ranked and evaluated according to the user data.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a database user data processing method and device. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to the data structure. In daily information management, a database is often required to store data, especially when the amount of data is large, it is necessary to use a database to store and maintain data. Various data can be stored in the database, such as user data, system data, employee data, etc. [0003] Mining and analyzing the massive data stored in the database can often obtain very valuable information. At present, in the field of data mining technology, operators can check and monitor through feature word matching, or extract data for calculation and processing to find rules . However, because the data stored in the database has many characteristics and a large amount, such a data mining method requires a lar...
