Abstract

The invention pertains to the recommendation system field in the information technology, and is particularly suitable for the recommendation application based on an e-commerce platform in an Internet environment. For shortages with existing collaborative filtering methods, a new characteristic-based collaborative filtering method is provided. According to the new method, the likes and dislikes of article characteristics of users in the goods purchasing process are fully taken into consideration, so a recommendation result which is a more accurate than a conventional collaborative filtering method in the condition that less neighbours of users/products are used, so that the recommendation system is more close to potential demands of website users. Overall, the new method is a collaborative filtering recommendation method having advantages of high efficiency and wide application range.
