Inferring social affinity based on interactions with search results

摘要

Techniques for inferring social affinity may include the following operations: obtaining information derived from online activity of a first party, where the online activity includes searches initiated by the first party, and where the information specifies interaction of the first party with content accessed through the online activity; determining, based on the information, that an amount of the interaction of the first party with the content exceeds a threshold; following the determining, identifying a second party who provided the content; adjusting, in a social graph for the first party, an affinity of the second party to the first party based on the amount of the interaction with the content; and using the affinity to promote search results output to the first party that contain content that is provided by the second party.

1. A method performed by one or more processing devices, comprising:
obtaining information derived from a search initiated by a first party, the information specifying i) particular content retrieved from one or more network resources identified by the search, the particular content associated with a subject, and ii) one or more interactions by the first party with the particular content; determining, based on the information, that an amount of the interaction of the first party with the particular content satisfies a threshold; in response to determining that the interaction of the first party with the particular content satisfies the threshold, identifying a second party that authored the particular content; determining that the first party has a pre-existing social connection with the second party in a social graph associated with the first party; in response to determining that the first party has the pre-existing social connection with the second party, adjusting, in the social graph associated with the first party, an affinity for the particular content associated with the second party with respect to the first party based on the amount of the interaction with the content authored by the second party; and updating search result rankings based on the affinity for the particular content to promote one or more first search results provided to the first party that contain additional content authored by the second party and ii) associated with the subject, while maintaining a ranking of one or more second search results provided to the first party that contain additional content i) authored by the second party and ii) independent of association with the subject.
