Finding and Approximating Top-k Answers in Keyword Proximity Search
Summary: Under data complexity, an efficient top-1 algorithm for keyword-proximity Q-fragments yields polynomial-delay algorithms for ranked enumeration and top-k computation. With query-and-data complexity, a θ-approximate top-1 yields (θ+1)-approximate ranked enumeration and top-k, giving the first provable approximate enumeration/top-k algorithms.
