Abstract: To estimate a more useful destination for users. A destination estimation apparatus 1 comprises a travel route history registration unit 13 storing a positional information history as a history of positional information of a user, a positional information acquisition unit 10 acquiring the positional information of the user, and a destination estimation unit 15 estimating a destination of the user by taking a location indicated by the acquired positional information as a start point based on the stored positional information history. The destination estimation unit 15 calculates a reaching level as a degree the user is reaching the estimated destination based on the stored positional information history, and re-estimates a new destination by taking the estimated destination as a start point when the calculated reaching level is equal to or more than a prescribed threshold value.

Abstract: 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 S202), 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 S207). 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 S212). 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.

Abstract: As an embodiment of the present invention, a place management system reads attributes of commodities from RFID-tags attached to the respective commodities located in a spatial area of a predetermined place, and determines an attribute of the place from the attributes read. The place management system is also able to store attribute inference rule information for determining the attribute of the place from the attribute information of commodities and to determine the attribute of the place on the basis of the attribute inference rule information from the attributes of the commodities recognized. Furthermore, the place management system has a place movement determiner for determining a movement of a place, and the place movement determiner is able to appropriately determine the movement when the place moves.
