Abstract

Under the present invention a set of values is first determined. Such values include: a relative total value 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 that is based on a total quantity of electronic interactions exclusively between the first user and the second user; a relative longevity value that is based on a length of time the first user and the second user have been electronically interacting; and a relative recency value 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, the normalized values are summed and compared to a predetermined standard.

Claims

1. A computer implemented method for calculating relationship strengths between users of a computerized network, comprising:

determining a relative total value based on a total quantity of electronic interactions between a first user and a second user of the computerized network;

determining a relative exclusive value based on a total quantity of electronic interactions exclusively between the first user and the second user;

determining a relative longevity value based on a length of time the first user and the second user have been electronically interacting, wherein the relative longevity value comprises a ratio of a sum of absolute interaction dates from a midpoint date between a first interaction and a last interaction between the first user and the second user, to a maximum sum of absolute interaction dates between the first user and all other users;

determining a relative recency value based on a recency of electronic interactions between the first user and the second user;

weighting the relative total value, the relative exclusive value, the relative recency value, and the relative longevity value to yield normalized values; and

calculating a relationship strength between the first user and the second user based on the normalized values, wherein the relationship strength is used to facilitate communications between the first user and the second user.

2. The method of claim 1, wherein the electronic interactions are selected from the group consisting of electronic mail messages, instant message, calendar entries, and contact list entries.

4. The method of claim 1, wherein the calculating step comprises summing the normalized values to yield the relationship strength between the first user and the second user.
