Claim:
1. A method implemented on a machine having at least one processor, storage, and a communication platform capable of connecting to a network for propagating trust to create an implicit social network, comprising: obtaining a content item; receiving a first user profile including information about a first set of activities of a first user with respect to the content item; receiving a second user profile including information about a second set of activities of a second user with respect to the content item; determining a similarity between the first user and the second user based on the first and the second sets of activities with respect to the content item; and generating an implicit relationship between the first user and the second user when the similarity with respect to the content item exceeds a threshold, wherein a ranking of a second content item determined based on the second user profile and an evaluation of the second user from other users implicitly related to the second user is to be used, based on the implicit relationship, to rank the second content item in a search result provided to the first user.
