User activity estimation system and a user activity estimating method
First Claim
1. A user activity estimation system which estimates a user activity from an article to which an article identifier for identification of an article is attached, comprising:
- attribute information holding means for holding the article identifier associated with article information;
probability information holding means for holding a relationship between a noun relating to the article information and a verb relating to the article associated with a conditional probability; and
activity estimation means for estimating a user activity upon detection of the article identifier based on contents held in the probability information holding means.

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. As a result, an appropriate service can be provided for the activity of the user.
