1. A computer-implemented method comprising: recognizing at least one person in at least one photo associated with a target user in a social network system, wherein the recognizing is based at least in part on social relevance, wherein the recognizing of the at least one person includes identifying at least one face, and applying a facial recognition algorithm to the at least one face, wherein the applying of the facial recognition algorithm to the at least one face comprises: matching facial features of the at least one face to facial features of at least one known face in a database, wherein the at least one known face is associated with a candidate person; determining a degree of social relevance between the candidate person and the target user; and determining the candidate person to be the at least one person in the at least one photo based on the degree of social relevance; in response to recognizing the at least one person, creating a new group in the social network system from the recognized at least one person in the at least one photo, wherein the new group is a previously non-existent social network group that includes the at least one person recognized in the at least one photo, and wherein a social network group is a set of socially connected users in the social network system; enabling the target user to verify that the at least one person recognized in the at least one photo is correctly recognized; enabling the target user to modify identification information associated with one or more people in the group if any person is incorrectly recognized; and associating the new group with the target user.
