Materializing Distributed Skyline Queries
Proceedings of the 6th International Conference on Agents and Artificial Intelligence, 2014During 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, 2013Due 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, 2012Let 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), 2018Skyline 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.

U-Skyline: A New Skyline Query for Uncertain Databases
IEEE Transactions on Knowledge and Data Engineering, 2013The skyline query, aiming at identifying a set of skyline tuples that are not dominated by any other tuple, is particularly useful for multicriteria data analysis and decision making. For uncertain databases, a probabilistic skyline query, called P-Skyline, has been developed to return skyline tuples by specifying a probability threshold.

Fuzzy Dominance Skyline Queries
2007Skyline 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 ...

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

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 ...
