## Abstract

In a first aspect of the present invention, provided are an information processing apparatus including a behavior-history acquisition unit configured to acquire behavior histories of first users identified by first-user identification information, a transmission-history acquisition unit configured to acquire information transmission histories of second users identified by second-user identification information, and a determination unit configured to determine identity between the first users and the second users on the basis of behavior details included in the behavior histories and transmission details included in the transmission histories; a method for processing information with the information processing apparatus; and a program using the information processing apparatus.

## Claims

### Claim 1

A method for processing information implemented by a computer, the method comprising the steps of:
acquiring, by a processor, behavior histories of a first user identified by a first-user identification information;
acquiring information transmission histories of a second user identified by a second-user identification information;
wherein the acquired information transmission histories of the second user are information acquired from a posted text, a text extracted from a posted sound, and text analyzed from a posted image;
determining an identity between the first user and the second user on the basis of at least behavior details, a plurality of degrees of association for a plurality of combinations, transmission details, and on the basis of profile information on the first user and profile information on the second user,
wherein the behavior details are included in the behavior histories and transmission details included in the transmission histories, and
wherein determining the identity between the first user and the second user on the basis of the plurality of degrees of association includes calculating a degree of association for each combination of one or more behavior histories of the first user and one or more transmission histories of the second user; and
displaying in response to determining the identity between the first user and the second user, an advertisement to the second user.
