Abstract: To accurately decide identity of a person using a plurality of target accounts, an information processing apparatus includes a determination unit and a decision unit. The determination unit determines a first acquaintance account group and a second acquaintance account group being associated with a first target account and a second target account, respectively. The decision unit decides identity of a person using the first target account and the second target account, based on similarity between a first person group and a second person group using the first acquaintance account group and the second acquaintance account group, respectively.

Abstract: An acquiring unit acquires information of the residence of one or more second users each having a second social media account related to a first user having a first social media account. An estimating unit estimates the residence of the first user from the information of the residence of the second user. A detecting unit detects a posting area at which the first user has posted on social media. A comparing unit compares the detected posting area with the estimated residence of the first user. A determining unit determines whether the posting area is an ordinary activity area or an extraordinary activity area for the first user based on the result of the comparison.

Abstract: Estimation of the range of activities of a target user is enabled in a relatively narrow range. A target user whose location is to be calculated has an account in social media. An offline friend determination means (111) calculates an offline friendship level on the basis of friend information obtained from at least one social media account related to the target user. The offline friendship level is the degree of friendship in real space between the target user and the at least one social media account related to the target user. A friend weight calculation means (112) calculates a weight to be assigned to the friend information on the basis of the offline friendship level. A candidate location score calculation means (113) calculates a score representing the possibility of the target user being active at a candidate location on the basis of the friend information and the corresponding weight.
