Approximate Boolean + Ranking Query Answering Using Wavelets


As more and more data become accessible, ranking query semantics such as ranked retrieval, possibly combined with Boolean query conditions, has gained a lot of attention lately. As the formulation of such queries is known to be difficult, we aim at providing quick approximate answers as cues for interactive query refinements. Toward the goal, we study… (More)
