Abstract: The present invention includes methods and systems for matching people. Current methods of and systems for matching people fail to use the best source for gathering information about a person: others who know that person. The present invention uses crowd-sourced tagging to determine attributes of the population of potential recommendations. The invention can also determine a user's preferences either implicitly, by leveraging the user's ratings of others and the crowd-sourced tags to determine the most important attributes to the user, or explicitly, by allowing a user to specify the most important attributes of people.
