Embodiment Construction

[0023] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0024] In the prior art, the method based on collaborative filtering is generally to find other users with similar interests for the user, and recommend the content they are interested in to the original user. It does not need to deal with attributes and content information of users and items. The hybrid method is to combine multiple types of recommendation methods in a certain way, o...

Abstract

Embodiments of the present invention provide a recommendation method, device, equipment, and computer-readable storage medium. The method includes: based on attribute tensors of a plurality of scored objects and attribute tensors of a plurality of unscored objects of the first user in the recommendation system, calculating a first predicted score of each unscored object by the first user; Multiple objects to be recommended of the first user of the first user, calculate the second predicted score of the first user for each object to be recommended; based on the first predicted score and the second predicted score, among multiple unscored objects and multiple recommended Determine at least one target recommendation object for recommendation. The embodiments of the present invention can improve recommendation diversity.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and in particular, to a recommendation method, device, equipment, and computer-readable storage medium. Background technique [0002] With the rapid development of Internet technology, online information is also growing explosively. Users are often at a loss when faced with a large number of choices. The proposal of the recommendation system can help users quickly locate the target they are interested in. On the one hand, the recommendation system can effectively improve the user experience when faced with a large number of choices. On the other hand, the recommendation system can help the platform to guide users and attract more users. [0003] At present, the existing recommendation methods mainly include content-based methods, collaborative filtering-based methods and hybrid methods. The content-based method is based on the content information of the item itsel...
