Patent number: 8200517Abstract: 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.Type: GrantFiled: August 2, 2006Date of Patent: June 12, 2012Assignee: NTT DoCoMo, Inc.Inventors: Kenji Sakamoto, Naoharu Yamada, Goro Kunito, Satoshi Tanaka, Kenichi Yamazaki
