Abstract

The invention discloses a cluster-based information pushing method and apparatus, a computer device and a storage medium. This method includes the steps of obtaining a similar user clustering result of a target node through a user-item bigraph corresponding to a user-scoring matrix, obtaining the final score between every item node in the target and the user-item bigraph to form a final scoring set according to the user-scoring matrix, a similar user clustering result and a preset final scoring algorithm, obtaining a corresponding item node set according to the final score greater than a preset scoring threshold in the final scoring set and pushing the item information corresponding to each item node in the item node set to a receiving terminal of the target user. This method avoids the sparse matrix and cold start problem inherent in the recommendation system, and has expansibility and high performance, realizing a more optimized information recommendation method.

Description

technical field [0001] The present invention relates to the technical field of information push, in particular to a clustering-based information push method, device, computer equipment and storage medium. Background technique [0002] At present, online shopping in Internet-based online shopping malls has become more and more frequent. When these online shopping malls recommend products to users, they usually use a recommendation algorithm based on collaborative filtering (collaborative filtering algorithm, the principle is that users like those with similar For example, if your friend likes the movie Harry Potter I, it will be recommended to you. This is the simplest user-based collaborative filtering algorithm), but when using collaborative filtering algorithm, you will encounter sparse Matrix and cold start problems, which affect the recommendation process. Contents of the invention [0003] The embodiment of the present invention provides a clustering-based informatio...
