16. A method, comprising acts of: deconstructing queries of a class into chunks of entities and clustering the chunks into clusters; computing answer densities for the corresponding clusters; comparing the answer densities of the clusters to answer density thresholds to determine answer consistency of the clusters; and returning answers for a query based on favorable comparison of the answer densities to the corresponding answer density thresholds and suppressing answers for the query based on unfavorable comparison of the answer densities to the corresponding answer density thresholds to maintain answer consistency.
