Abstract: A social networking system provides a short, unbiased biographical summary for a user of the social networking system. The short biography includes a few relevant biographical information items selected from the user's profile and is displayed on the profile page. The short biography may be displayed with a set of photographs also selected from the profile for their relevance. Relevance may be based on various information including temporal relevance and relevance to the viewing user. Display of the short biography allows a viewer to easily find current biographical information about the user in an abbreviated format.

Abstract: A social networking system notification system is scaled so a user is notified of an event when a unit or level of notification utility has been reached. For the average user, a single event may be noteworthy enough for which to receive a notification. However, when this user is especially important or highly connected (or received a large number of interactions), that user will have decreasing utility for each additional comment he has received. To manage these types of situations, and avoid inundating users with notifications that are of less utility to the user, the notifications are filtered/aggregated so that these users are notified less often. The notification scheme is optimized for each user, so the user is notified only when he has reached a level of notification utility.
