The top-k ranking is based on some scoring function in deterministic applications. However, in uncertain applications, such a clean definition does not exist, since the process of reporting a tuple in a top-k answer does not depend only on its score but also on its membership probability. This work introduces an approach to processing top-k queries based on… CONTINUE READING
