Problems solved by technology

In the recommendation method based on video content, the accuracy of the recommendation result of the keyword matching method is not high, and it is impossible to perceive the hotspots of user interest; the ontology description method has no definite abstract description form due to the large amount of semantic information and complex structure of the video , it is difficult to extract movie features

Embodiment Construction

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0021] The present invention mainly uses attribute descriptions to represent film features and stratifies by type, focuses on user interest hotspots by analyzing the concentration of different levels, and uses time forgetting factor and linear superposition method of film models to track user interest changes and responds to user interest in real time. Video feedback, adjust the user interest preference model, and improve the accuracy and adaptability of video recommendations.

[0022] Such as figure 1 Shown is a structural diagram of a...

Abstract

The invention provides a personalized film recommendation system and method based on attribute description, comprising a candidate film data base, a viewing record data base, a user interest preference model calculation module and a film recommendation model. The personalized film recommendation system uses the attribute description to represent the film feature and is hierarchized according to the types and analyses the user interest hot spot of concentration ratios of different hierarchy and tracks the user interest change using the time forget factor and film model linear superposition method, responds the feedback of the user on the film at real time, adjusts the user interest preference model and increases the accuracy and adaptability of recommended film.

Description

technical field [0001] The invention relates to the field of network media services, in particular to a film personalized recommendation system and method. Background technique [0002] With the development of computer network technology and video compression technology, video applications have been widely used. The development of video services comes from the promotion of rich video content, which will inevitably lead to an increase in the number of videos and diversification of content. For individual users, the rich video content increases the user's choice on the one hand, but on the other hand increases the difficulty for the user to watch the video selection. Oftentimes, different people have different areas of interest, selected by and in different ways, and that interest changes with what they watch and over time. Therefore, in addition to providing rich video content, modern video services should also implement personalized information extraction services for indi...
