Abstract: A method can include receiving a request for content including an attribute for a school. The method can analyze a social graph to identify a first set of nodes representing members, which can connect to a first node representing a first school, the social graph can be represented by a graph data structure having nodes representing various entities and edges representing associations between entities. The method can analyze a social graph to identify a second set of nodes representing members, the second set of nodes representing members connecting to a second node representing a school. The method can generate a central tendency of a number of the first set of nodes representing members and a number of the second set of nodes representing members and using the central tendency and a number of the first set of nodes representing members, can determine an index number for the first school.
