Embodiment Construction

[0104] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0105] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for dividing user groups in the present application, which may specifically include the following steps:

[0106] Step 101, capture the user ID;

[0107] The user identifier may be information that can represent a certain user, for example, a user ID (Identity, identification number), a cookie, a Mac (Media Access Control, media access control) address, and the like.

[0108] In this embodiment of the application, the server may record the user's data through the website log and store it in the database.

[0109] When dividing user groups, user IDs can be fetched from the database.

[0110] Step 102, establis...

Abstract

The embodiment of the invention provides a user group partitioning method and device. The method comprises the steps of capturing user identifiers; building a joint behavior relation between the user identifiers; obtaining a user node diagram; in the user node diagram, recognizing one or more core user groups according to the joint behavior relation; in the one or more core user groups, dividing one or more target user groups according to the joint behavior relation. On one hand, manual rule setting is avoided, different user groups have different distribution features, although individual behavior differences are large, the potential relation of the user is more stable, and the user group partitioning accuracy of the user groups is improved in a diagram-based user group partitioning mode; on the other hand, by roughly partitioning the core user groups, the data size is greatly decreased, the partitioning efficiency is improved, and the user group partitioning accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of computer processing, in particular to a user group division method and a user group division device. Background technique [0002] With the rapid development of the Internet, the amount of information on the Internet has increased dramatically. The excessive information makes it impossible for people to efficiently obtain what they need, and the efficiency of information use decreases instead. [0003] Therefore, major websites usually divide their oriented users into different user groups to provide more refined services. [0004] In addition, in some security detection scenarios, users also need to be divided into different user groups. [0005] For example, on e-commerce websites, criminals maliciously increase store points through virtual transactions and other means, commonly known as "swiping diamonds". In order to maintain order, the website needs to identify the group of "swiping diamon...
