Embodiment Construction
[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0042] It can be seen from the background technology that in the prior art, the probability values of viewing interest preferences of different users at different time periods are mainly calculated based on topic models. However, the topic model has high complexity and poor versatility when calculating user interest, and the topics trained by the topic model are relatively abstract and not very explanatory. There are also certain differences between different...

The invention discloses a method and system for evaluating user interest. By establishing an interest tag library, the interest tag library includes program tags and various program parameters under the program tags; based on the program tags, the user's program indicators on each program tag are calculated. Parameters; normalize the relative value of the program indicator parameters of the current user under each program label that are not relative to all users, and obtain the normalized value corresponding to each program indicator parameter; weighted calculation of each program label corresponding to the current user The normalized value corresponding to each program index parameter of the program can obtain the current user's degree of interest in the program corresponding to each program label. Through the above disclosed method, the calculation of the degree of interest is obtained based on the pre-established program index parameters on the program label, and the process is simple. Therefore, the user's degree of interest in each program tag can be quickly and accurately obtained through the method for evaluating the user's degree of interest disclosed in the present invention.
Description
technical field [0001] The invention relates to the technical field of new media, and more specifically relates to a method and system for evaluating user interest. Background technique [0002] With the rapid development of the new media industry, making different pushes for different user portraits has become one of its important businesses. Among them, the user's viewing preference is an important part of the user portrait process. The user's viewing preference is mainly measured by user interest. The degree of user interest refers to the degree to which the user is interested in each interest tag. [0003] For the calculation of user interest degree, in the prior art, the probability values of viewing interest preferences of different users at different time periods are mainly calculated based on topic models. The topic model realizes calculation of user interest mainly through training. However, the topic model has high complexity and poor versatility when calcula...
