Abstract

A computer-implemented method of introducing users of a service includes sending a suggestion to a first user of a service and suggesting an introduction of a second user to a third user of the service. The second and third users are both identified as contacts of the first user in a contact list of the first user and the second and third users satisfy predefined selection criteria with respect to shared contacts, comprising users identified in contact lists of both the second and third users. The method also includes receiving, from the first user, a response to the suggestion; and upon receiving a positive response to the suggestion from the first user, sending the introduction to at least one of the second and third users.

Claims

1. A computer-implemented method of introducing users of a service, performed by a server system having one or more processors and memory storing one or more programs for execution by the one or more processors, the method comprising:

at the server system;

identifying, by the server system, among contacts of a first user in a contact list of the first user, second and third users who are not in each other'"'"'s contact lists and who satisfy predefined selection criteria with respect to one or more shared contacts other than the first user, wherein;

(i) the one or more shared contacts comprise one or more users identified in contact lists of both the second and third users, and

(ii) the predefined selection criteria are based, at least in part, on a score corresponding to a count of other users who each have both the second and third users in their contact lists and a threshold for the score to satisfy in order to identify the second and third users;

sending, by the server system, a server-generated suggestion to the first user of the service, suggesting an introduction of the second user to the third user of the service;

receiving from the first user a response to the suggestion; and

upon receiving a positive response to the suggestion from the first user, sending, by the server system, the introduction to one of the second and third users.

2. The method of claim 1, including maintaining as private the contact list of each user, and sending the introduction only with explicit permission of the first user.

3. The method of claim 1, wherein:

the contact list of each user is maintained as private; and

the introduction is sent only when the second and third users are authorized to receive online status information of the first user, the online status information of the first user indicating the first user'"'"'s availability to exchange messages with other users through the server system.

4. The method of claim 1, including:

receiving an acceptance of the introduction from the second user;

receiving an acceptance of the introduction from the third user; and

upon receiving acceptances from the second and third users, authorizing, by the server system, the second and third users to share online status information with each other, the online status information indicating the second and third users'"'"' availability to exchange messages with each other through the server system.

5. The method of claim 1, including comparing, by the server system, contact metrics of the second and third users with respect to the first user to select one of the second and third users as the recipient of the introduction, and sending the introduction to the selected one of the second and third users.

6. The method of claim 1, including asking the first user to select one of the second and third users as the recipient of the introduction.

7. The method of claim 1, including sending the introduction to the third user, and determining whether the third user accepts the introduction, and if the third user accepts the introduction, sending an invitation to the second user, and if the second user accepts the invitation, authorizing the second and third users to receive online status information of each other.

8. The method of claim 1, wherein the identifying includes identifying a list of candidate pairs, each comprising a pair of contacts from the contact list of the first user, and excluding from the list of candidate pairs any respective pair of contacts where an introduction to one of the contacts was previously rejected by the other of the contacts, and wherein the second and third users comprise one of the pairs of contacts in the list of candidate pairs.

9. The method of claim 1, wherein the contact list of the first user comprises a subset of users identified in the address books of the first user, wherein the subset comprises users authorized to receive online status information of the first user and the online status information of the first user indicates the first user'"'"'s availability to exchange messages with other users.

10. The method of claim 1, wherein the predefined selection criteria are based, at least in part, on a predefined combination of contact list entry scores for the second and third users, wherein a respective contact list entry score for the second user is determined, at least in part, based on one or more of:

frequency, quality, and timing of communications between the second user and a respective shared contact; and

a respective contact list entry score for the third user is determined, at least in part, based on one or more of;

frequency, quality, and timing of communications between the third user and the respective shared contact.

11. A computer-implemented method of identifying pairs of users to introduce, performed by a server system having one or more processors and memory storing one or more programs for execution by the one or more processors, the method comprising:

at the server system;

accessing contact lists of multiple users of a service;

identifying, by the server system, from the accessed contact lists, pairs of users who are not in each other'"'"'s contact lists but who have common contacts in their contact lists, each identified pair of users having respective first and second users;

generating a score for each identified pair of users, wherein the score is determined, at least in part, based on;

(i) metrics associated with the common contacts of the pair of users, and

(ii) a count of other users who each have both the first and second users of the identified pair of users in their contact lists;

selecting, by the server system, a subset of the identified pairs of users in accordance with selection criteria, the selection criteria including a threshold for the score for each respective pair of users;

after selecting the subset of the identified pairs of users, identifying, by the server system, a potential sponsor for each pair of users in the selected subset, wherein the potential sponsor is a user of the service distinct from the first and second users;

with respect to a pair of users in the selected subset, sending, by the server system, a server-generated suggestion to the potential sponsor, suggesting an introduction of the respective first and second users of the pair of users; and

upon receiving a positive response to the suggestion from the potential sponsor, sending, by the server system, the introduction to one of the first and second users of the pair of users.

12. The method of claim 11, wherein the method includes, prior to selecting the subset of the identified pairs of users, excluding from the identified pairs of users any respective pair of users where an introduction to one of the users was previously rejected by the other of the users.

13. The method of claim 11, wherein the score for the identified pair of users is determined, at least in part, based on a predefined combination of contact list entry scores for the identified pair of users, wherein a respective contact list entry score for the first user of the identified pair of users is determined, at least in part, based on one or more of:

frequency, quality, and timing of communications between the first user of the identified pair of users and a respective common contact of the identified pair of users; and

a respective contact list entry score for the second user of the identified pair of users is determined, at least in part, based on one or more of;

frequency, quality, and timing of communications between the second user of the identified pair of users and the respective common contact of the identified pair of users.

14. The method of claim 11, including maintaining as private the contact list of each user, and sending the introduction only with explicit permission of the potential sponsor.

15. The method of claim 11, wherein:

the contact list of each user is maintained as private; and

the introduction is sent only when the first and second users are authorized to receive online status information of the potential sponsor, the online status information of the potential sponsor indicating the potential sponsor'"'"'s availability to exchange messages with other users through the server system.

16. The method of claim 11, including comparing contact metrics of the first and second users with respect to the potential sponsor to select one of the first and second users as the recipient of the introduction, and sending the introduction to the selected one of the first and second users.
