Embodiment Construction

[0031] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0032]In recent years, the humanized recommendation system with thousands of people and faces has become the core standard configuration of major applications (for example, mobile APP). The premise of personalized recommendation is to understand users, which requires the creation of user portraits to express users. User portrait can be understood as using relevant user behaviors (such as text, pictures, consumption behavior, etc.) in the ap...

Abstract

The invention discloses a user profile vector generation method and device. The method comprises the steps of obtaining video information watched by a user according to a video click history of the user; searching a video description vector corresponding to a video according to the acquired video information, the video description vector being generated by analyzing an image contained in the video; and generating a user profile vector based on the found video description vector. Therefore, the image content description of the video is vectorized, and the user image vector is constructed basedon the watching history of the user, so that the description of the user profile can be quickly realized according to the watching behavior of the user. Furthermore, the user profile vector can be updated in real time in different modes according to the accumulation of the watching history, so that the description of the user profile is more accurate, and the generation and updating processes arelighter.

Description

technical field [0001] The present invention relates to a recommendation system, in particular to a method and device for generating a user portrait vector. Background technique [0002] The video industry has developed rapidly in recent years, among which short videos are especially popular due to their social nature, and appear in a large number of short video social applications that mainly distribute short videos of personal status. Build the system. [0003] In order to improve user-friendliness and reduce inefficient background calculations, these applications need to recommend the right video content to the right user in the right way at the right time. Appropriate content means that the content fits the taste of the target user. Appropriate time means that the recommended content fits the context at that time. Appropriate method means that the recommended content presentation method makes users feel comfortable. Appropriate user means that the recommended user reall...
