Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] figure 1 A flow chart of a method for extracting user features provided by an embodiment of the present invention, the method may include:

[0024] Step S100, acquiring the user's activity log;

[0025] It should be noted that the activity log records the operation behavior generated during the user's network operation, including the operation behavior generated during the user's visit to any website. The user's activity log can be a data table or a di...

Abstract

The embodiment of the present invention discloses a user feature extraction method and related devices, including: obtaining the user's activity log, which records the operation behavior generated during the user's network operation; layered extraction and operation behavior from the operation behavior Corresponding to the characteristics of the operation object, the operation object characteristics of different levels are obtained. With the decrease of the number of levels, the data granularity of the operation object characteristics is finer; for the operation object characteristics of the same level, according to the operation object characteristics corresponding to Manipulate behaviors to generate user features. It can be seen that in the embodiment of the present invention, since the operation object features are divided into different levels, the operation object features of different levels decrease as the number of levels decreases, the finer the data granularity of the operation object features, in the embodiment of the present invention, the finer-grained operation can be Fine-grained user features are mined from the object feature level to meet the needs of some usage scenarios that require fine-grained user features.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a user feature extraction method and a related device. Background technique [0002] User characteristics are mainly used to describe the characteristic attributes of a user, such as: gender, age, occupation, hobbies, regions, or the regularity of users visiting websites. The mining of user characteristics is based on the basic data of website visits. The statistics and analysis of the relevant data are used to discover the characteristics and attributes of the users. The mining of user characteristics is of great significance to the marketing strategy of the network. For example, through the mining of user characteristics, user preferences are discovered, and personalized recommendation services corresponding to user preferences are generated, so as to recommend recommendation services that meet user needs for users. . [0003] However, the existing technology mainly m...
