Abstract

The embodiment of the invention discloses a method for improving commodity recommendation diversity, and solves the problem that recommended commodities are lack of diversity. The method comprise: obtaining similar users by utilizing a Canopy algorithm and a K-means algorithm according to user data; according to the total order data, constructing a knowledge graph, and obtaining an SPU associatedwith the real-time interest of the user; and obtaining a commodity recommendation list according to the similar users and the SPUs associated with the real-time interests of the users.

Description

technical field [0001] The invention belongs to the field of product recommendation, and in particular relates to a method and system for improving the diversity of product recommendation. Background technique [0002] Commodity recommendation algorithms in this field mainly include the following types: content-based recommendation, data mining-based recommendation, combination recommendation and memory-based collaborative filtering algorithm. [0003] Content-based recommendation technology, after generating the user feature model, recommends according to the user model. The recommendation result is intuitive and easy to understand, and it can recommend special users without domain knowledge. However, the scope of this method is narrow. [0004] The recommendation technology based on data mining mainly recommends by generating association rules. It is not limited by the recommended content and does not require domain knowledge. However, the generation of association rules i...
