A noun and a verb is mapped as the information about an article to which an article identifier such as a radio tag, etc. is attached and a user activity, thereby estimating a user activity from the article to which the article identifier is attached and providing a user with appropriate information. An article identifier for identification of an article is associated with article information and stored (step S), and the relationship between a noun relating to the article information and a verb relating to the article are associated with a conditional probability and held in the probability information holding unit (step S). Upon detection of the article identifier, the probability of the verb to the noun is calculated based on the contents held in the probability information holding unit, thereby estimating a user activity (step S). Thus, based on the detection result of the article identifier attached to the article, the activity of the user on the article can be estimated. As a result, an appropriate service can be provided for the activity of the user.

User activity estimation system and a user activity estimating method

A wireless tag determination system includes a detection information storage configured to store information detected from a wireless tag by a tag reader, as detection information. A determination requesting unit is configured to request a determination for reliability of existence of the wireless tag within a detection range of the tag reader. A reliability determination unit is configured to determine the reliability by use of the detection information, in response to the request.

Wireless tag determination system and wireless tag determination method

To overcome problems there is to be provided useful information to a user, by counting the number of detected RF tags. As a means for solving the problems an information-providing serveraccording to the present invention acquires IDs of RF tag readers disposed near by the Ferris wheel, when there has been presented to the information providing server, as a notifying condition, the condition that a user desires to receive an e-mail on the occasion of the number of persons waiting in line for a Ferris wheel having become seven or less. Then after having acquired the number of plural IDs of the RF tags detected by the RF tag readers having the acquired IDs, the information-providing serveracquires attribute information of the RF tags. The information providing servercounts the number of IDs of RF tags whose attribute is a person, referring to the attribute information. When the counted result has become seven or less, the information providing servertransmits an e-mail notifying to the effect that the congestion has been relieved to the mobile terminal

Server apparatus and information providing method

To group ID tags distributed in a larger area than the coverage of a tag reader, a parameter which represents a measure of the strength of relationship among a plurality of ID tags is stored in a parameter storage database. Values of the parameter are increased and decreased according to the number of pieces of ID information detected simultaneously in the ID tags by a mobile tag reader. A plurality of ID tags are judged as belonging to the same group according to values of the parameter stored in the parameter storage database, thereby making it possible to group ID tags distributed in a larger area than the coverage of a tag reader.

Tag grouping system and tag grouping method

A management system includes a manager determining unit determining a manager who manages an article, a user determining unit determining a user related to the article based upon detection of a wireless tag by a wireless tag reader, and an attribute information holding unit holding a wireless tag identifier, the manager, and the user while associating them with each other. The wireless tag identifier uniquely identifies a wireless tag.

Management system and management method for managing a wireless tagged article

When a tag selectorreceives a plurality of RFID tag IDs detected by an RFID tag reader, by a tag ID receiving part, it acquires nonspecificities corresponding to these RFID tag IDs from an attribute information DB. The tag selectorselects an RFID tag ID with a nonspecificity smaller than a predetermined selected tag threshold by a tag ID selecting partand notifies a service determining deviceof it. A nonspecificity is an index indicating a diversity of use of an article to which a corresponding RFID tag is attached. Therefore, the service determining devicedetermines a service to be provided for the user, based on the RFID tag ID with the low nonspecificity value, whereby it becomes feasible to promptly provide the service very likely desired by the user.

Tag selector, tag selection system, and tag selection method

In a tag reader/writeraccording to the present invention, first, a temporary ID receiverreceives a temporary ID unit of temporary IDs of RFID tags, anddetected by another tag reader/writer, and stores them into a temporary ID storage DB. When the tag reader/writerdetects RFID tags, andwithin a communication area of its own, a temporary ID acquirerthereof acquires temporary IDs of those RFID tags and stores them into the temporary ID storage DB. Thereafter, the tag reader/writermakes a temporary ID comparatorcompare temporary ID units stored, to specify a temporary ID corresponding to a difference between them, based on the result of the comparison. When the temporary ID is a decrease, it is determined to be a lost article, and a message of the lost article is sent. When the temporary ID is an increase, it is determined to be a newly purchased article, and related advertisement information is provided.

Article management apparatus and information processing methods

When an information providing serveraccording to the present invention acquires attribute information items of RFID tagstodetected in a shopping cart and in the vicinity thereof, it transmits these attribute information items to a rule serverWhen the received attribute information items satisfy a predetermined combination, the rule serverreturns presentation information corresponding to the combination to the information providing serverWhen the information providing serverreceives this presentation information, it sends the presentation information to a mail address of mobile equipmentacquired from the attribute information items. This permits the user to readily figure out a dish that can be made from cooking ingredients put in the cart.
