Abstract

The invention relates to a score prediction method and device, computer equipment and a storage medium. The score prediction method comprises the steps: receiving a user ID and an article ID, and obtaining a user preference feature, an article preference feature, comment information corresponding to a user, and comment information corresponding to an article; obtaining a text feature matrix corresponding to the comment information; obtaining comment information usefulness according to the text feature matrix, the user preference features and the article preference features, and obtaining swarmintelligence features according to the comment information usefulness and the text feature matrix; mapping the user preference features and the article preference features to a feature space of the swarm intelligence features to obtain user hidden features and article hidden features; and obtaining a prediction score of the user for the article. According to the score prediction method, the groupintelligence features are obtained through the comment information of the users and the articles, and then the hidden features of the articles are extracted through the group intelligence features toobtain the matching scores of the users and the articles, and the scoring accuracy of the recommendation system can be effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a score prediction method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of information technology and the Internet, online shopping has become the main way for people to shop. After purchasing the product, users will rate the product and write comments to express their opinions. Among them, the score describes the degree to which the user likes the product, and the comment information describes the specific reasons why the user likes or dislikes the product. When shopping online, user reviews on products on e-commerce websites or APPs can help other potential consumers understand the overall picture of the product and help potential consumers make purchase decisions. [0003] However, the existing score prediction methods are mainly based on the topic model to model text reviews, which do not really dig out ...
