Threshold queries are an important class of queries that only require computing or counting answers up to a specified threshold value. To the best of our knowledge, threshold queries have been largely disregarded in the research literature, which is ...
Top-k queries are widely used in analyzing and processing uncertain data. In the uncertain database, the xtuple consists a number of alternatives which are mutually exclusive, the independence still remains among the x-tuples. Probabilistic threshold ...
In this paper we present the Threshold Join Algorithm (TJA), which is an efficient TOP-k query processing algorithm for distributed sensor networks. The objective of a top-k query is to find the k highest ranked answers to a user defined similarity ...
