11. The system of claim 9 , wherein the executable and operational data are further effective to cause the one or more processors to select one or more inferred interests for the user from among the at least one characterizing interests of the plurality of communities by: calculating a closeness for each of the plurality of communities; ranking the at least one characterizing interest of the plurality of communities according to the closeness of the plurality of communities; and selecting the one or more inferred interests for the user according to the ranking.
9. A system for identifying interests comprising one or more processors and one or more memory devices operably coupled to the one or more processors, the one or more memory devices storing executable and operational data effective to cause the one or more processors to: evaluate social media data of a user; identify from the social media data a plurality of communities each community of the plurality of communities including a plurality of friends of the user, each community of the plurality of communities identified according to social media interconnections and interactions among friends of the user in each community; for each community of the plurality of communities, identify common interests from personal interests of the plurality of friends of the user of the each community; identify, for each community of the plurality of communities, at least one characterizing interest of the common interests identified for the each community, the at least one characterizing interest being absent from any self-identified interests of the user in the social media data; and select one or more inferred interests for the user from among the at least one characterizing interests of the plurality of communities; wherein the executable and operational data further effective to cause the one or more processors to identify, for each community of the plurality of communities, at least one characterizing interest of the common interests identified for each community of the plurality of communities by, for each community: performing a first ranking of the common interests identified for the each community according to popularity of the common interests identified within the each community; and selecting the at least one characterizing interest for the each community according to the first ranking; and wherein the executable and operational data are further effective to cause the one or more processors to select the one or more inferred interests for the user from among the at least one characterizing interests of the plurality of communities by: evaluating frequency of interaction of the user with the plurality of friends of the user corresponding to each community of the plurality of communities; ranking the at least one characterizing interests of the plurality of communities according to the frequency of interaction of the user with the plurality of friends of the user corresponding to each community of the plurality of communities; and selecting the one or more inferred interests according to the ranking.
