INFORMATION PROCESSOR, METHOD OF OUTPUTTING DATA, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve the problem with constructing an information filter device corresponding to as many as several million users: wherein the amount of data about user preference information showing individuals' preferences becomes so enormous that the process of filtering the data takes a huge amount of time. SOLUTION: This information processor comprises a data accepting part that accepts two or more data, and a data output part which selects one or more data from two or more data for output according to the group preference information of a group to which one user belongs and user difference preference information. The information processor reduces the amount of data for the information showing preferences, and enables detailed information filtering for each individual. Because each individual user's preference information does not exist, each user's privacy is protected. COPYRIGHT: (C)2005,JPO&NCIPI
