Embodiment 1

[0026] figure 1 The flow chart of the method for processing user portraits provided by Embodiment 1 of the present invention, this embodiment is applicable to situations where data such as user preferences and personal habits need to be accurately obtained, and this method can be executed by a device for processing user portraits. It can be implemented in the form of software and / or hardware, and the device can generally be integrated in a server to facilitate the processing of massive data. Such as figure 1 As shown, the method specifically includes:

[0027] S110. Obtain user history information.

[0028] Among them, user history information can usually reflect personalized information such as the user's personal habits and preferences for corresponding things, and it can reflect various label information of the user. Among them, the user's label information can include "NBA", " Shopping", "Architecture", "Gourmet", "Martial Arts Drama" and "Travel", etc. The user histor...

Embodiment 2

[0034] On the basis of the above-mentioned embodiments, this embodiment provides a preferred implementation of the operation of "converting the user's historical information into a semantic vector corresponding to the user based on the language model, as a user portrait of the user". figure 2 It is a flow chart of the method for processing user portraits provided by Embodiment 2 of the present invention, such as figure 2 As shown, the method includes:

[0035] S210. Obtain user history information.

[0036] S220. Determine at least two tags of the user according to the user history information, and map them into tag vocabulary, and combine each tag vocabulary into tag text.

[0037] Tags can reflect the characteristics and commonalities between users and other users, and are associated and textual. Changes in personal concerns can be fully reflected through tags, making it easier to discover user preferences and habits. Multiple labels can represent the characteristics of...

Embodiment 3

[0055] As a collection of tags that describe user characteristics, user portraits have a wide range of applications. On the basis of the above-mentioned embodiments, this embodiment provides a specific application example of the user portrait processing method in the field of information recommendation based on regions. image 3 It is a flow chart of the method for processing user portraits provided by Embodiment 3 of the present invention, such as image 3 As shown, the method includes:

[0056] S310. Obtain user history information.

[0057] S320. Convert the user history information into a semantic vector corresponding to the user based on the language model, and use it as a user portrait of the user.

[0058] S330. Determine the interest similarity between users according to the user portraits, thereby forming a user group.

[0059] In this embodiment, the user portrait includes various points of interest of the user. Since each user portrait follows a unified grammatic...

Abstract

The embodiment of the invention discloses a processing method and device of a user portrait, a server and a storage medium. The processing method of the user portrait includes: acquiring user historyinformation; and converting the user history information into a semantic vector, which corresponds to a user, on the basis of a language model, and using the same as the user portrait of the user. According to the embodiment of the invention, the user portrait is expressed in a manner of the semantic vector, expression is accurate, a data form is unified, operations of introducing the semantic vector under various application scenes for calculation are facilitated, thus a factor of the user portrait is considered, and effects of accurate and concise meaning expression and easy application areachieved.

Description

technical field [0001] Embodiments of the present invention relate to big data processing technologies, and in particular to a method, device, terminal and storage medium for processing user portraits. Background technique [0002] User portrait is a means to outline the characteristics of target users, which can be expressed as descriptive label attributes for users, so that these label attributes can be used to outline the real personal characteristics of users in many aspects. In turn, user portraits can be used to mine user needs, analyze user preferences, and provide users with more efficient and targeted information delivery and a user experience closer to personal habits by matching user portraits. [0003] There are many existing methods for obtaining user portraits. The tag attributes describing the user can be extracted from various information associated with the user, and then the user portrait can be obtained. However, factors such as the type, source, and data...
