Uncertain Location based Range Aggregates in a multi

2009-5-30 · There are many applications for the range query operation against uncertain data. In this paper, we focus on the distance based range aggregates computation where the location of the query point is uncertain while the target data are conventional points (i.e, certain points ). In general, an “uncertain location based query”, denoted by Q, is a

In general, an uncertain query Q is a multidimensional point that might appear at any location x following a probabilistic density function pdfðxÞwithin a region Q:region. There is a number of applications where a query point may be uncertain.

CiteSeerX — Uncertain Location based Range

Recently, 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 multi-dimensional space. We first formally introduce the problem, then propose a general filtering-and-verification framework to solve the problem.

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].

Range-max queries on uncertain data ScienceDirect

2018-6-1 · In this paper we study the range-max query on uncertain data, which asks for statistics on the maximum value of the data inside a query range. Formally, we consider database records of the form ( p,v,α ),where p is a point in R d (attribute values of the record) with d ≥ 1 a constant, along with a positive scalar value v ∈ R + and a

Approximation algorithms for aggregate queries on uncertain

2020-11-3 · In this paper, the results of aggregate queries on uncertain data are defined to include all possible values and their corresponding probabilities. Dynamic programming is then used to solve the Distribution Sum (DSUM) algorithm using a Greedy-based Distribution Sum and a Binary Merge based Distribution Sum approximation algorithms, which both can be applied to tuple-level and attribute-level
