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 an evaluation method and system for the user interest degree. The evaluation method comprises the steps of establishing an interest label database, wherein the interest label database includes program labels and parameters of each program under the program labels; calculating program index parameters of users on each program label based on the program labels, carrying out normalization processing on relative values of the program index parameters of the current user under each program label relative to all users to obtain the normalized value corresponding to each program index parameter; performing weighted calculation on the normalized values of the program index parameters under each program label corresponding to the current user to obtain the interest degree ofthe current user for the programs corresponding to each program label. According to the method disclosed by the invention, the calculation for the interest degree is obtained based on the program index parameters on the pre-established program labels, and the process is simple. Therefore, the evaluation method disclosed by the invention for the user interest degree can quickly and accurately obtain the interest degree of the user for each program label.
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...
