The σ-neighborhood skyline queries

Information Sciences, 2015
Skyline queries have recently attracted considerable attention for their ability to return data points from a given dataset that are not dominated by any other points. This study extends the concept of skyline queries in the development of a ?-neighborhood skyline query (?-N skyline query).

The Farthest Spatial Skyline Queries

Information Systems, 2013
Pareto-optimal objects are favored as each of such objects has at least one competitive edge against all other objects, or ''not dominated''. Recently, in the database literature, skyline queries have gained attention as an effective way to identify such pareto-optimal objects. In particular, this paper studies the pareto-optimal objects in perspective

Materializing Distributed Skyline Queries

Proceedings of the 6th International Conference on Agents and Artificial Intelligence, 2014
During the last decade, data management and storage have become increasingly distributed. Advanced query operators, such as skyline queries, are necessary in order to help users to manipulate the huge amount of available data by identifying a set of interesting data objects.

Parallel Computation of Skyline Queries

2013 IEEE 21st Annual International Symposium on Field-Programmable Custom Computing Machines, 2013
Due to stagnant clock speeds and high power consumption of commodity microprocessors, database vendors have started to explore massively parallel co-processors such as FPGAs to further increase performance. A typical approach is to push simple but compute-intensive operations (e.g., prefiltering, (de)compression) to FPGAs for acceleration.

Algorithms for range-skyline queries

Proceedings of the 20th International Conference on Advances in Geographic Information Systems, 2012
Let S be a set of n points in Rd where each point has t ≥ 1 real-valued attributes called features. A range-skyline query on S takes as input a query box q e Rd and returns the skyline of the points of q ∩ S, computed w.r.t. their features (not their coordinates in Rd).

Skyline Diagram: Finding the Voronoi Counterpart for Skyline Queries

2018 IEEE 34th International Conference on Data Engineering (ICDE), 2018
Skyline queries are important in many application domains. In this paper, we propose a novel structure Skyline Diagram, which given a set of points, partitions the plane into a set of regions, referred to as skyline polyominos. All query points in the same skyline polyomino have the same skyline query results.

Fuzzy Dominance Skyline Queries

2007
Skyline is an important and recent proposal for expressing user preferences. While no one best row exists, Skyline discards rows which are worse on all criteria than some other and retrieves non-dominated or the best ones that match user preferences. Nevertheless, some dominated rows could be interesting to user requirement, but they will be rejected ...

Skyline Adaptive Fuzzy Query

2011
In recent years, Skyline query based on a multi-dimensional space has become a hot topic in the research of database technology according to its potential applications in data mining and visualization of databases. A variety of high-efficient Skyline query approaches is proposed, such as BNL (Blocked Nested Loop), NN (Nearest Neighbour) and BBS (Branch

Subspace Skyline Queries

2012
Skyline queries help users make intelligent decisions over complex data, when different and often conflicting criteria are considered. Such queries return a set of data points that are not dominated by any other point on all dimensions. Skyline queries have been studied in centralized systems and more recently in distributed environments, such as web ...
