1. A computer-implemented method for querying a reputation system, comprising: obtaining a query specifying one or more dimensions and one or more quantiles, wherein each of the specified one or more dimensions is associated with one of the specified one or more quantiles, and wherein the dimensions comprise skills; obtaining a set of items in the reputation system with reputations scores in the one or more dimensions, wherein the items comprise users; generating a ranking of the set of items based on a closeness of a subset of the reputation scores for each of the items to the one or more quantiles, wherein the closeness of the subset of the reputation scores to the one or more quantiles is based on a rectilinear distance between the subset of the reputation scores and the one or more quantiles; and providing the ranking of the set of items in a response to the query.
