Range Aggregationedit. A -bucket value source based aggregation that enables the user to define a set of ranges - each representing a bucket. During the aggregation process, the values extracted from each document will be checked against each bucket range and "bucket" the relevant/matching document. Note that this aggregation includes the from value and excludes the to value for each ...

Efficient Computation of Range Aggregates Against Uncertain Location Based Queries using Filtering-and-Verification Algorithm . S.Praveen Kumar 1, R.V.Krishnaiah 2. Section:Research Paper, Product Type: Isroset-Journal Vol.1, Issue.3, pp.56-61, May-2013 Online published on Jul 07, 2013

In this paper, we study the problem of efficiently computing range aggregates in a dimensional space when the query location is uncertain. Specifically, for a query point Q whose location is uncertain and a set S of points in a dimensional space, we want to calculate the aggregate (e.g., count, average and sum) over the subset S′ of S such that for each p ∈ S′, Q has at least ...

Large amount of uncertain data is inherent in many novel and important applications such as sensor data analysis and mobile data management. A probabilistic threshold range aggregate (PTRA) query retrieves summarized information about the uncertain objects satisfying a range query, with respect to a given probability threshold. This paper is the first one to address this important type of query.

Uncertain data are inherent in many applications such as environmental surveillance and quantitative economics research. Considerable research efforts have been put into the field of analysing uncertain data. In this paper, we study the problem of processing the uncertain location based range aggregate in a -dimensional space. We first formally introduce the problem, then propose a ...

However, though range aggregate query on uncertain data is very important in practice, this problem remains unexplored. A range aggregate query (RA query) on certain data returns summarized information about objects satisfying a given query range, such as the total num-ber of qualified objects [19]. This type of query is important since users may be interested only in aggregate information ...
