Patent US 8,073,786

A set of values is first determined. Such values include: a relative total value with respect to other users that is based on a total quantity of electronic interactions between a first user and a second user of the computerized network; a relative exclusive value with respect to other users that is based on a total quantity of electronic interactions exclusively between the first user and the second user; a relative longevity value with respect to the other users that is based on a length of time the first user and the second user have been electronically interacting; and a relative recency value with respect to the other users that is based on a recency of electronic interactions between the first user and the second user. Once determined, the values are weighted to yield normalized values. To calculate the relationship strength that includes a value indicating how strong a relationship between the first user and the second user is with respect to a relationship between the first user and other users, the normalized values are summed and compared to a predetermined standard.
