Identifying top content contributors in online social networks

A system, comprising:

• a memory comprising instructions executable by one or more processors;
• and
• one or more processors coupled to the memory and operable to execute the instructions, the one or more processors being operable when executing the instructions to:
• access a plurality of user profiles corresponding to a plurality of users and a plurality of content objects, wherein:
• the users belong to a social network;
• and
• each of the users has contributed at least one of the content objects to the social network;
• rank the users in descending order based on a number of content objects each of the users has contributed to the social network;
• represent in log space ranks of the users versus in log space numbers of content objects contributed by the users;
• determine a threshold rank based on an increasing rate of the ranks of the users, a decreasing rate of the numbers of content objects, and a predetermined value in the log space;
• and
• identify from among the users, those users ranked at and above the threshold rank as high-volume content contributors for the social network.

One or more computer-readable tangible and non-transitory storage media embodying software operable when executed by one or more computer systems to:

• access a plurality of user profiles corresponding to a plurality of users and a plurality of content objects, wherein:
• the users belong to a social network;
• and
• each of the users has contributed at least one of the content objects to the social network;
• rank the users in descending order based on a number of content objects each of the users has contributed to the social network;
• represent in log space ranks of the users versus in log space numbers of content objects contributed by the users;
• determine a threshold rank based on an increasing rate of the ranks of the users, a decreasing rate of the numbers of content objects, and a predetermined value in the log space;
• and
• identify from among the users, those users ranked at and above the threshold rank as high-volume content contributors for the social network.
