Problems solved by technology
[0006] 1. The analysis dimension of the existing technology is single, only analyzing the user's purchase behavior, resulting in relatively limited results of user brand preference and a small coverage of users;
[0007] 2. Listing user brand preference data through pure statistics is not easy to summarize user characteristics, and it is impossible to form a systematic description of user sensibility;
[0008] 3. When using brand preferences as user characteristics to portray user portraits, if it is necessary to recommend products or push advertisements to users, the brands preferred by users will generally be recommended, which will greatly restrict the marketing measures of the network service platform, making marketing Measures do not have the desired effect

The invention discloses a method and device for extracting user characteristic data and relates to the technical field of computers. One embodiment of the method comprises the steps that preference values of users for different characteristic identifiers are determined according to behavior data of the users; according to the preference values of the users for different characteristic identifiersand preset characteristic item sets, preference values of the users for different characteristic items are calculated, and the characteristic items and the preference values of the users for the characteristic items serve as characteristic data of the users. According to the embodiment, the behavior data of the users and character traits of the users can associated, each character trait of the users are quantified to more three-dimensionally and visually describe sensible characteristics of the users, a rich commercial application prospect can be supported, and the effects of marketing measures are greatly improved.
Description
Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for extracting user characteristic data. Background technique [0002] With the rapid development of Internet technology, various network service platforms such as online shopping, online learning, and online consulting have penetrated into every corner of people's daily life. While providing services to users, network service platforms generally conduct commercial activities such as precision marketing or advertising on users.
