ITEM RECOOMMENDATION SERVICE SYSTEM, AUTOMATIC SCORING APPARATUS AND METHOD FOR ITEM RECOOMMENDATION BASED ON COLLABORATIVE FILTERING IN THE SYSTEM

摘要

The present invention relates to an item recommendation service system, and a method and apparatus for recommending an item based on collaborative filtering in the system. The item recommendation service system collects evaluation information on items and item-related information from one or more terminal devices, and recommends one or more items by giving a weighted value to item evaluation of each user through credit-based collaborative filtering based on the collected evaluation information and item-related information. Therefore, since a bigger weighted value is provided to a user who makes a reliable evaluation, accuracy of estimated evaluation can be increased, and since different evaluation standards of different users are reflected, accuracy of recommendation of items can be increased.
