Presenting contacts to a social networking system user based on user interactions with additional users and with groups

A computer program product comprising a computer readable storage medium having instructions encoded thereon that, when executed by a processor, cause the processor to:

• store information describing one or more interactions between a user of a social networking system and one or more additional users of the social networking system through a messaging application associated with the social networking system;
• store information describing one or more interactions between the user of the social networking system and one or more groups of users of the social networking system, each group including a plurality of additional users through the messaging application associated with the social networking system;
• determine scores associated with the one or more additional users, a score associated with an additional user indicating a likelihood of the user interacting with the additional user based at least in part on interactions between the user of the social networking system and the additional user;
• determine scores associated with the one or more groups of users, a score associated with a group indicating a likelihood of the user interacting with the group based at least in part on interactions between the user of the social networking system and the group;
• select a set of contacts for the messaging application associated with the social networking system based at least in part in part on the scores associated with the one or more additional users and the scores associated with the one or more groups of users;
• and
• communicate information identifying the set of contacts to a client device for presentation to a user in an interface of the messaging application that presents information associated with contacts in the set of contacts, information with a contact initiating communication with the content via the social networking system when accessed.

A system, comprising:

• a processor;
• a non-transitory memory including instructions, which when executed by the processor cause the processor to perform steps of:
• storing information describing one or more interactions between a user of a social networking system and one or more additional users of the social networking system through a messaging application associated with the social networking system;
• storing information describing one or more interactions between the user of the social networking system and one or more groups of users of the social networking system, each group including a plurality of additional users through the messaging application associated with the social networking system;
• determining scores associated with the one or more additional users, a score associated with an additional user indicating a likelihood of the user interacting with the additional user based at least in part on interactions between the user of the social networking system and the additional user;
• determining scores associated with the one or more groups of users, a score associated with a group indicating a likelihood of the user interacting with the group based at least in part on interactions between the user of the social networking system and the group;
• selecting a set of contacts for the messaging application associated with the social networking system based at least in part in part on the scores associated with the one or more additional users and the scores associated with the one or more groups of users;
• and
• communicating information identifying the set of contacts to a client device for presentation to a user in an interface of the messaging application that presents information associated with contacts in the set of contacts, information with a contact initiating communication with the content via the social networking system when accessed.
