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

Methods, systems, and apparatus, including computer programs for identifying, using historical interactions associated with a first user, contact groups, where the first user is associated with each contact group, are provided. A score, with respect to a second user, is calculated for each contact group based on an amount of interaction between the second user and the respective contact group, thereby deriving a plurality of scores. A first contact group is determined. The first contact group has a first score in the plurality of scores that satisfies a predetermined threshold. A contact group suggestion is generated, responsive to the determining, that comprises an invitation to add the second user to the first contact group. The first user is notified of the contact group suggestion.

Systems and methods for providing contact group member suggestions

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving an identifier associated with a user of a social networking service, identifying one or more first services provided by a first service provider, determining that the user is a user of the one or more first services based on the identifier, identifying first contacts of the user within each of the one or more first services, and generating a social vicinity index based on the first contacts, the social vicinity index including one or more potential contacts for the user within the social networking service.

Social vicinity service for social networks

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.

Implementations of the present disclosure include generating one or more suggested social circles based on an analysis of past user interactions. The user can accept the suggested social circle and use it to distribute digital content. Generating a suggested social circle can include determining, for each of various sets of contacts, an initial score that represents a strength of the particular user's affinity to the set as a whole based on prior interactions of the particular user with the set, and determining, for each member of each set, an individual score that represents an average strength of the particular user's affinity to the member based on the interactions. An overall score for each set is calculated based on the initial score for the set and the individual scores of each member in the set. Based on the overall scores, at least one of the sets is identified for presentation as a suggested social circle to the particular user. Social circle data corresponding to the suggested social circle is transmitted to display a representation of the suggested social circle on a client device associated with the particular user.

Generating suggestions for user groups in social networks

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.
