Embodiment Construction
[0045] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0046] The existing user profile update mainly relies on user data collection. Therefore, for those users with low activity, because user data cannot be collected, their user profile cannot be updated in time. The inventor found through research and analysis that similar users often gather together for activities, for example, people with the same hobby, income, age or occupation often gather together offline. Therefore, based on this feature, the inventor proposed the following user portrait update scheme, by collecting data of different users gathering together offline, and analyzing the similarity between different users according to the collected offline data, and then according to the user similarity The relationship updates the ...

The invention discloses a user portrait updating method and device and a storage medium. The method comprises the following steps: collecting offline activity data of a user; calculating similarities of different users according to the offline activity data; user portraits are updated, and the user portraits of the low-activity users are updated by adopting the user data of the users with high similarity with the low-activity users. According to the method, the offline activity data of different users are collected, the similarity between the users is calculated through the offline activity data, and when the user portraits are updated, the users (namely the low-activity users) with insufficient user data are replaced with the data corresponding to the users with high similarity with the users, so that the user portraits are updated. Therefore, the user portraits of the users with insufficient user data can be updated in time, and the user portraits of the users with low activeness can better reflect the actual characteristics of the users.
Description
technical field [0001] The present invention relates to the technical field of user portraits, in particular to a method, device and storage medium for updating user portraits. Background technique [0002] User portrait is a technology that describes the characteristics of users from different dimensions through a variety of different information. User portrait can well reflect the characteristics of users, so it has been widely used in various fields. In the prior art, the data required to generate a user portrait is generally obtained by filling in basic information data from the user, and the behavior characteristic data of the user is also collected through behavior data and calculated by statistical methods. But every user is growing and changing, and their occupation, hobbies, consumption habits, etc. may change, so their user portraits are also updated accordingly. [0003] At present, the update of user portraits mainly relies on the continuous collection of user b...
