Automated aging of contacts and classifying relationships

摘要

One or more interactions between a first user and a second user of a social networking system are identified. Each respective interaction of the one or more interactions is scored based on a group score and a time penalty. The group score is based on the number of users in the respective interaction and the time penalty is based on a time between a current time and a time of a last interaction between the first user and the second user. A relationship ranking that measures the first user's affinity towards the second user is determined, where the relationship ranking comprises one or more interaction scores. An indicator representing the relationship ranking is sent to a client for display.
