Abstract: In one aspect, a computerized method provides an online social network, wherein online social network comprises a set of nodes, wherein each node represents a user and a set of relationships between each node. The computerized method identifies a set of users that are members of the same family. The computerized method identifies each node of the set of users that are members of the same family. When a member of the set of users interacts with another member of the set of users; the computerized method determines an interaction and determines a family-relationship status between the member and the other member; and scores the interaction. The computerized method generates a family bonding index based on the family relationship status of the member and the other member and the score the interaction. The computerized method updates the set of relationships of the of social network based on the family bonding index.
