Abstract
A messaging system receives a contact list from a client device. The messaging system receives information about ephemeral content associated with contacts in the contact list and information about the active now status of contacts in the contact list. Based at least in part on the ephemeral content information and the active now status of the contacts in the contact list, the messaging system generates scores for contacts in the contact list using a unified scoring model. The unified scoring model receives as input information about multiple features associated with the user of the messaging system and the contact in the contact list and generates a score representing a probability that the user will interact with the contact upon being presented with the contact. The messaging system ranks the contacts in the list based on the generated scores and transmits the contact list to the client device for display in an activity unit.
