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 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.
