Embodiment Construction

[0072] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0073] like figure 1 Shown is a work flow chart of a notification method for a website project of the present invention, including:

[0074] Step S101, obtaining interest ratings of multiple users on multiple items;

[0075] Step S102, determine the set of neighboring items with the target item, the set of neighboring items is the K other items with the highest similarity with the target item, the similarity between the target item and the other items is determined by the user-to-target Calculation of the interest degree score of the item and the other items, the union set is the union set of users who have the interest degree score of the target item and one of the other items, and the users who do not have the union set in the target item or the other items The interest score of is filled with the combined weighted scoring method;...

Abstract

The invention relates to the technical field related to notification of websites, in particular to a method and system for carrying out notification on the website projects. The method for carrying out notification on the website projects comprises the steps of (1) obtaining interestingness grades of a plurality of users to a plurality of projects, (2) determining the set of projects adjacent to a targeted project, (3) determining a predicted grade of a targeted user to the targeted project according to the interestingness grades of the targeted user to the adjacent projects, and (4) sending a notice of the targeted project to the targeted user when the predicted grade of the targeted user to the targeted project exceeds a preset grade threshold. Compared with the prior art, the recommendation effect of the grade prediction method of the method and system for carrying out notification on the website projects is better, and quality of recommended commodities is greatly improved.

Description

technical field [0001] The present invention relates to the relevant technical field of website notification, in particular to a method and system for notifying website items. Background technique [0002] Nowadays, in order to increase sales and improve user experience, e-commerce websites attach great importance to personalized recommendations for users, and the most popular recommendation algorithm is Collaborative Filtering Algorithm. [0003] Collaborative filtering is to filter information through the behavior records of a large group of people, which can be divided into two types of algorithms: user-based and item-based. The user-based collaborative filtering algorithm is to find the similar user group of the target user, and then predict the target user's rating of the item according to the rating of the target item by the user group. The project-based collaborative filtering algorithm is to find the project group similar to the target project, and then predict the ...
