Systems and method for generating contact suggestions are provided in which one or more suggested contacts are identified from a set of contacts associated with a user. This includes identifying in historical communications in a user account associated with the user, one or more groups of contacts. Scores are generated for contacts in the identified groups of contacts, including generating a contact score for a respective contact by accumulating score contributions for a plurality of the identified groups of contacts that include the respective contact. One or more suggested contacts are identified in accordance with the generated scores. A contact suggestion is sent based on the suggested contacts for display to the user. The contact suggestion includes a suggested contact with a generated score that is above a predefined threshold.

Generating contact suggestions

In some implementations, a method includes, at a computing device, identifying a first recipient of a draft electronic communication prepared by a user. A is score is obtained for a second recipient using respective messages in a plurality of historical messages in a user account associated with the user. The second recipient is a sender or receiver of the respective messages. There is suggested to a user, second recipient for the draft electronic communication in accordance with a condition that both the first recipient and the second recipient shared a single electronic communication and the score for the second recipient satisfies a predefined score threshold. The single electronic communication was communicated at a time prior to identifying the first recipient.

A computer system having one or more processors and memory receives seed data comprising contacts specified for a draft communication, selects at least a subset of the seed data as a seed set of contacts, and identifies one or more suggested contacts based on the seed set. Identifying the suggested contacts includes: identifying in historical communications in a user account, groups of contacts that include one or more of the contacts in the seed set; generating scores for contacts in the identified groups of contacts, including generating a contact score for a respective contact by accumulating score contributions for a plurality of the identified groups of contacts that include the respective contact; and identifying the one or more suggested contacts in accordance with the generated scores. The computer system sends a contact suggestion based on the suggested contacts for display in conjunction with the draft communication.
