1. A user grouping apparatus comprising:
- a storage that stores a wireless ID aggregate structure, which is an aggregated data structure of a plurality of wireless IDs set up for each wireless management apparatus used by a user, in which each wireless ID is associated with a location and time, where and when the corresponding wireless ID was read out from a wireless ID tag by a wireless ID management apparatus, and wireless ID related information which is information associated with the corresponding wireless ID, hierarchically constructed by classifying the plurality of wireless IDs based on the readout location and further by classifying them based on the readout time such that;
(i) the wireless ID aggregate structure includes a respective set of wireless ID aggregates for each of a plurality of physical locations, (ii) each wireless ID aggregate is for a given time and includes a plurality of wireless IDs of a plurality of users read at such time;
an evaluator, which extracts one or more feature quantities from wireless ID related information of one or more of the wireless ID aggregates, where the feature quantities are indicative of preferences of one or more of the plurality of users, and which evaluates affinity between a first user'"'"'s preferences as detected from a first wireless ID aggregate and a second user'"'"'s preferences as detected from a second wireless ID aggregate;
a classifier, which classifies the first user and the second user in one group when the affinity is stronger than a predetermined threshold value; and
a filter, which filters the wireless ID aggregate structure and returns a subset of the wireless ID related information in response to a user request, such that an output screen generator may generate an output screen displaying the subset of the wireless ID related information to the user.

Abstract
An RFID aggregate storage stores a radio-frequency ID aggregate structure. The RFID aggregate structure is an aggregated data structure of a plurality of RFIDs, in which each RFID is associated with a location and time read out from a RFID tag, and RFID related information, hierarchically constructed by classifying RFIDs based on the readout location and further by classifying them based on the readout time. A proximity evaluator evaluates the proximity between the first user'"'"'s RF ID aggregate and the second user'"'"'s RFID aggregate. A user classifier classifies the first user and the second user in one group when the proximity is smaller than a predetermined threshold value.

5. A user grouping method comprising the steps of:
-
reading out from a storage apparatus a wireless ID aggregate structure, which is an aggregated data structure of a plurality of wireless IDs set up for each wireless management apparatus used by a user, in which each wireless ID is associated with a location and time, where and when the corresponding wireless ID was read out from a wireless ID tag by a wireless ID management apparatus, and wireless ID related information which is information associated with the corresponding wireless ID, hierarchically constructed by classifying the plurality of wireless IDs based on the readout location and further by classifying them based on the readout time such that;
(i) the wireless ID aggregate structure includes a respective set of wireless ID aggregates for each of a plurality of physical locations, (ii) each wireless ID aggregate is for a given time and includes a plurality of wireless IDs of a plurality of users read at such time;extracting one or more feature quantities from wireless ID related information of one or more of the wireless ID aggregates, where the feature quantities are indicative of preferences of one or more of the plurality of users; evaluating affinity between a first user'"'"'s preferences as detected from a first wireless ID aggregate and a second user'"'"'s preferences as detected from a second wireless ID aggregate; classifying the first user and the second user in one group when the affinity is stronger than a predetermined threshold value; filtering the wireless ID aggregate structure and returns a subset of the wireless ID related information in response to a user request; and generating an output screen displaying the subset of the wireless ID related information to the user.

6. A user terminal that communicates with a server, the server comprising:
-
a storage that stores a wireless ID aggregate structure, which is an aggregated data structure of a plurality of wireless IDs set up for each wireless management apparatus used by a user, in which each wireless ID is associated with a location and time, where and when the corresponding wireless ID was read out from a wireless ID tag by a wireless ID management apparatus, and wireless ID related information which is information associated with the corresponding wireless ID, hierarchically constructed by classifying the plurality of wireless IDs based on the readout location and further by classifying them based on the readout time such that;
(i) the wireless ID aggregate structure includes a respective set of wireless ID aggregates for each of a plurality of physical locations, (ii) each wireless ID aggregate is for a given time and includes a plurality of wireless IDs of a plurality of users read at such time; andan evaluator, which extracts one or more feature quantities from wireless ID related information of one or more of the wireless ID aggregates, where the feature quantities are indicative of preferences of one or more of the plurality of users, and which evaluates affinity between a first user'"'"'s preferences as detected from a first wireless ID aggregate and a second user'"'"'s preferences as detected from a second wireless ID aggregate; a classifier, which classifies the first user and the second user in one group when the affinity is stronger than a predetermined threshold value and adds group information to a user profile of the first user and the second user; and a filter, which filters the wireless ID aggregate structure and returns a subset of the wireless ID related information in response to a user request, and the user terminal comprising a memory that stores the wireless ID aggregate structure; a sender that sends the wireless ID aggregate structure to the server; a receiver that receives from the server the user profile to which the group information is added; and an output screen generator, which generates an output screen displaying the subset of the wireless ID related information to the user.
