Abstract

An online social network is managed using one server for database management tasks and another server, preferably in a distributed configuration, for CPU-intensive computational tasks, such as finding a shortest path between two members or a degree of separation between two members. The additional server has a memory device containing relationship information between members of the online social network and carries out the CPU-intensive computational tasks using this memory device. With this configuration, the number of database lookups is decreased and processing speed is thereby increased.

Claims

1. A computer-implemented method comprising:

receiving, at one or more computing systems from a client device, a query associated with a first user of a social network;

retrieving, using one or more processors associated with the one or more computing systems, information based on the query, the information representing a user profile associated with a second user of the social network;

determining, using the one or more processors, a profile format for the user profile based on a visibility preference of the second user specifying a threshold degree of separation, wherein the profile format is set to full profile if a degree of separation between the first user and second user is less than or equal to the threshold degree of separation, the full profile format permitting the first user to view an entirety of the user profile data of the second user, and wherein the profile format is set to mini-profile if the degree of separation between the first user and second user is greater than the threshold degree of separation, the mini-profile format permitting the first user to view only a limited portion of the user profile data of the second user; and

transmitting information to the client device, based on the profile format, representing the user profile associated with the second user.

2. The method of claim 1, wherein the query comprises an identifier for the second user.

3. The method of claim 1, wherein the threshold degree of separation specified in the visibility preference is 1, 2, 3, or All degrees of separation.

4. The method of claim 3, wherein if the visibility preference is set to All, then setting the profile format to full profile.

5. The method of claim 3, wherein if the visibility preference is set to some value other than “

All”

, then;

determining, using the one or more processors, the degree of separation between the first user and the second user; and

comparing the degree of separation to the visibility preference of the second user.

6. The method of claim 5, wherein the determining the degree of separation between the first user and the second user is based on a social graph stored in a dedicated memory device.

7. The method of claim 1, wherein determining the profile format comprises retrieving a visibility preference of the second user from a database.

8. The method of claim 1, further comprising:

retrieving information indicating a degree of separation between the first user and the second user by accessing a social graph stored in a dedicated memory device.

9. The method of claim 1, further comprising:

retrieving updates to relationship information from the database; and

updating the social graph based on the updates to relationship information.

10. One or more machine-readable non-transitory storage media embodying software that is operable when executed by one or more processors associated with one or more computer systems to:

receive, at the one or more computing systems from a client device, a query associated with a first user of a social network;

retrieve, from a database, information based on the query, the information representing a user profile associated with a second user of the social network;

determine, using the one or more processors, a profile format for the user profile based on a visibility preference of the second user specifying a threshold degree of separation, wherein the profile format is set to full profile if a degree of separation between the first user and second user is less than or equal to the threshold degree of separation, the full profile format permitting the first user to view an entirety of the user profile data of the second user, and wherein the profile format is set to mini-profile if the degree of separation between the first user and second user is greater than the threshold degree of separation, the mini-profile format permitting the first user to view only a limited portion of the user profile data of the second user; and

transmit information to the client device, based on the profile format, representing the user profile associated with the second user.

11. A system comprising:

a database; and

a graph server comprising;

a dedicated memory device;

a processor; and

one or more non-transitory machine-readable storage media comprising software for causing the processor to execute instructions to;

receive information identifying a first user of a social network and a second user of a social network;

access a social graph stored on the dedicated memory device; and

an application server comprising;

a processor; and

one or more non-transitory machine-readable storage media comprising software for causing the processor to execute instructions to;

receive, from a client device, a query associated with a first user of a social network;

retrieve, from the database, information based on the query, the information representing a user profile associated with a second user of the social network;

determine a profile format for the user profile based on the visibility preference of the second user specifying a threshold degree of separation, wherein the profile format is set to full profile if a degree of separation between the first user and second user is less than or equal to the threshold degree of separation, the full profile format permitting the first user to view an entirety of the user profile data of the second user, and wherein the profile format is set to mini-profile if the degree of separation between the first user and second user is greater than the threshold degree of separation, the mini-profile format permitting the first user to view only a limited portion of the user profile data of the second user; and

transmit information to the client device, based on the profile format, representing the user profile associated with the second user.

12. The system of claim 11, wherein the query comprises an identifier for the second user.

13. The system of claim 11, wherein the threshold degree of separation specified in the visibility preference is 1, 2, 3, or All degrees of separation.

14. The system of claim 13, wherein if the visibility preference is set to All, then setting the profile format to full profile.

15. The system of claim 13, wherein if the visibility preference is not set to “

All”

, then;

determine, using the one or more processors, the degree of separation between the first user and the second user; and

compare the degree of separation to the visibility preference of the second user.

16. The system of claim 11, wherein the storage media of the graph server further comprises instructions to:

retrieve updates to relationship information from the database; and

update the social graph based on the updates to relationship information.

17. The system of claim 11, wherein the storage media of the graph server further comprises instructions to:

retrieve information indicating a degree of separation between the first user and the second user by accessing a social graph stored in a dedicated memory device.

18. The system of claim 11, wherein determining the profile format comprises retrieving a visibility preference of the second user from a database.
