15. The method of claim 10 , further comprising defining suitable answers of a cluster according to at least one of an absolute basis or a cross-sectional basis.
10. A method, comprising acts of: computing result densities of clusters of entity chunks, the chunks derived from a class of queries; comparing the result densities of the clusters to density thresholds to determine a result consistency of the clusters; returning results for a query based on favorable comparison of the result densities to the corresponding density thresholds; and suppressing results for the query based on unfavorable comparison of the result densities to the corresponding density thresholds, to maintain the result consistency.
