Trust propagation through both explicit and implicit social networks
First Claim
1. A method for propagating trust to create an implicit social network, the method comprising:
- calculating a first feature vector for a first user;
calculating a second feature for a second user;
comparing the first feature vector with the second feature vector to calculate a similarity value;
determining whether the similarity value falls within a threshold; and
if the similarity value falls within the threshold, recording a relationship between the first user and the second user in a first user profile and a second user profile.

Abstract
The present invention is directed towards systems and methods for trust propagation. The method according to one embodiment comprises calculating a first feature vector for a first user, calculating a second feature for a second user and comparing the first feature vector with the second feature vector to calculate a similarity value. A determination is made as to whether the similarity value falls within a threshold. If the similarity value falls within the threshold, a relationship is recorded between the first user and the second user in a first user profile and a second user profile.
