Along with the rapid developing of computer network, a massive amount of streaming data appears in various fields, such as financial information, meteorological information, WSN, etc. Top-k query is one of the popular algorithms in traditional database. However, traditional query algorithms are not applicable to uncertain database. Therefore, aimed at the massive amount of uncertain data in network, this paper is to present top-k query, the algorithm by sliding-windows, based on characteristics of streaming data.
