Abstract:
A system and method to estimate a location relating to a user who has not filled in information about the location in a profile field in social media such as a microblog. The system and method estimates association between a user in social media and a location includes the steps of acquiring a first content posted to the social media by a first user associated with a first location, determines regional localization of the first content on the basis of the first location, acquires a second content posted to the social media by a second user not associated with a location, determine the degree of a relationship between the first content and the second content, and associating the first location with the second user on the basis of the localization and the degree of the relationship.

Claim (Index 1):
A method for estimating association between a user in social media and a location, the method comprising the steps of:\n acquiring, at a processor, a first content posted to the social media by a first user associated with a first location; determining, by the processor, regional localization of the first content on a basis of the first location; acquiring, by the processor, a second content posted to the social media by a residence unidentified second user not associated with a location; determining, by the processor, the degree of a relationship between the first content and the second content; and associating the first location with the second user on the basis of the localization and the degree of the relationship, wherein said associating the first location (l) with the second user comprises: acquiring, by the processor, messages sent by said second users, and for each second user (u) having a message indicating a local event (e): computing a first probability estimation P(l|e) that the event attracts attention of first users living in the first location, the first users being of a set of users whose residence has been identified; computing a second probability estimation P(e|u) that the first users has indicated the local event in a message; and computing a third probability estimation P(l|u) that the second user is a resident of the first location wherein P(l|u) is a function of said P(l|e) and P(e|u).
