USE HISTORY SERVER DEVICE, SERVICE RETRIEVAL SERVER DEVICE, COMMUNICATION TERMINAL, AND SERVICE RECOMMENDATION METHOD

摘要

PROBLEM TO BE SOLVED: To enable the recommendation of a service fitted to the state or taste of a user.

SOLUTION: A service retrieval server device makes an inquiry for the evaluation score of a service that is a candidate of a retrieval result to at least one of user history server devices 3-1 to 3-3 designated in a user's request. The selected use history server calculates the evaluation score according to the state or taste designated in the user's request by matching the state or taste with the state or taste in the service use included in a use history database. Therefore, the service can be recommended not by simply calculating the ranking by the number of accesses or the number of users, but by using information showing that users of what state (position, time, activity state) used the service.
