CONTENTS RECOMMENDATION SYSTEM, CONTENTS RECOMMENDATION DEVICE AND CONTENTS RECOMMENDATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a large scale resource required for achieving a highly accurate contents recommendation technique.

SOLUTION: A preference determination information providing section 32 in a user device 12 transmits a user's evaluation of contents as preference determination information to a preference information providing server 13. A preference determination information acquisition section 54 in the preference information providing server 13 accumulates the preference determination information and stores the same in a preference determination information storing section 56. A preference information creating section 58 creates a preference vector of the user based on the preference determination information and stores the same in a preference information storing section 60. A contents list acquisition section 36 in the user device 12 adds filtering conditions to the preference information and requests the contents list to the preference information providing server 13. A contents list creating section 64 in the preference information providing server 13 extracts identification information of contents which has a high similarity with the preference information and satisfies the filtering conditions to create a contents list and transmits the same to the user device 12.
