Problems solved by technology

[0011] However, when the advantages of the user data accumulated earlier in the distribution statistics are too obvious, relying solely on the above weight adjustments is still unable to quickly and timely match the descriptive label attributes with the characteristics of the current user data.
Therefore, the hysteresis of user portrait update has become a difficult problem in this field

Embodiment Construction

[0040] The technical solutions of the present invention will be further specifically described below through examples.

[0041] see figure 1 As shown in the flow chart, the method for establishing a user portrait based on big data according to the present invention includes the following steps:

[0042] First, in step 101, a user portrait including descriptive tag attributes is established according to previously accumulated user data. Users access network services such as webpages or APPs provided by one or more service providers through user equipment UT (such as smart phones, computers, and personal digital terminals), such as news clients, microblogs, online shopping websites, E-ticket platforms, hotel booking sites, online music players, etc. In the process of using these network services, first of all, the user's access itself, input information, click on a link, and implement operations through the interactive interface such as adding attention, unfollowing, scoring, ...

Abstract

The invention discloses a big data-based user portrayal establishing method and a user portrayal management system. The method comprises the following steps: establishing a temporary user portrayal by utilizing the user behaviors and / or contents in a valid time period; enabling the temporary portrayal to inherit a descriptive label attribute matched with the user behaviors and / or contents in the valid time period from a user portrayal; and when the user behaviors and / or contents in the valid time period are not matched with the descriptive label attribute of the user portrayal, newly establishing a descriptive label attribute in the temporary user portrayal. According to the method and system disclosed in the invention, the user portrayal can be effectively maintained according to the data of the user behaviors and / or contents, and especially when the user behaviors and / or contents have step shift, the influences of the cumulative data which has advantage on the distribution statistical law and does not accord with the current contents and behaviors of the user can be rapidly obsoleted.

Description

technical field [0001] The invention relates to the field of network data analysis and processing, in particular to a method for establishing a user portrait based on big data and a user portrait management system. Background technique [0002] Big data technology is an information processing technology that takes all data resources of any system as the object and discovers the correlation relationship between data. It has been widely used in Internet process optimization, targeted news and advertisement push, and user personalized services. It has become a powerful background support behind network services. [0003] User portrait is an important application of big data technology. Its goal is to establish descriptive label attributes for users in many dimensions, so as to use these label attributes to outline the real personal characteristics of users in many aspects, and then use user portraits to mine Analyze user needs, analyze user preferences, and provide users with ...
