Webmassive and rapid data streams, such as sketch [9], [7], [23] and space-saving [15]. These synopsis structures are suitable for frequency estimation, heavy-hitter, and top-k queries. However, a direct adaptation of the aforementioned stream compressing techniques over graph-edge or graph-node streams lose the underlying structural information ... WebOur filter can accurately estimate both cold and hot items, giving it a genericity that makes it applicable to many stream processing tasks. To illustrate the benefits of our filter, we deploy it on three typical stream processing tasks and experimental results show speed improvements of up to 4.7 times, and accuracy improvements of up to 51 times.

Cuckoo Matrix: A High Efficient and Accurate Graph Stream …

WebThe basic idea of graph stream analysis is to estimate the exact query result of a graph stream based on the sampling results. Colorful triangle counting [28] is an example. However, it needs to know the number of triangles and the maximum number of trian-gles of an edge to set the possibility value. This is not feasible in practical applications. WebWe consider two different scenarios for query estimation: (1) A graph stream sample is available; (2) Both a graph stream sample and a query workload sample are available. Algorithms for different scenarios are designed respectively by partitioning a global sketch to a group of localized sketches in order to optimize the query estimation accuracy.
