Skyline Snippets

2011
There is a strong demand for a deep personalization of search systems for many Internet applications. In this respect the proper handling of user preferences plays an important role. Here we focus on the efficient evaluation of the Pareto preference operator for structured data in very large databases.

The skyline theatre

Proceedings of the 13th Participatory Design Conference: Short Papers, Industry Cases, Workshop Descriptions, Doctoral Consortium papers, and Keynote abstracts - Volume 2, 2014
This installation at the 13th Participatory Design Conference (PDC) is based on a site-specific project to establish a space in Windhoek, Namibia, devoted to outdoor performance and the display of outdoor sculptures. For this purpose we designed an amphitheatre space called "The Skyline Theatre".

Skyline and reverse skyline query processing in SpatialHadoop

Data & Knowledge Engineering, 2019
Abstract In this paper, we study the problem of skyline and reverse skyline computation using SpatialHadoop, an extension of Hadoop that enhances its capabilities with spatial awareness. The exploitation of spatial indexing structures and the spatial properties of data can exploit MapReduce-based methods by reducing the reading, writing ...

Skyline Queries

Datenbank-Spektrum, 2016
Many applications face the problem that users are overwhelmed by the large amount of available data. In some cases an objective ranking function can be used to order data items by their relevance – similar to the top 10 results displayed by a Web search engine.

Skyline Travel Routes: Exploring Skyline for Trip Planning

2014 IEEE 15th International Conference on Mobile Data Management, 2014
In this paper, given a spatial range Q and a set of query points specified by users, the goal of this paper is to return the travel routes that fulfill two requirements: 1.) travel routes should contain all those query points specified, and 2.) travel routes should be within the spatial range Q.

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.

On Possibilistic Skyline Queries

2011
This paper deals with Skyline queries in the context of possilistic databases, where uncertain attribute values are represented by possibility distributions. In this framework, Skyline queries aim at computing the extent to which any tuple from a given relation is possibly/certainly not dominated by any other tuple from that relation.

Neural skyline filter for accelerating skyline search algorithms

Expert Systems, 2014
AbstractThe skyline search problem has been identified as one of the key problems in database research. None of the developed skyline search algorithms include the use of a filter to facilitate the search process. This paper proposes a novel modification involving the use of skyline filters to reduce the search space of a skyline problem by removing ...

Limitations of Skyline Algorithms

Proceedings of the 2015 International Conference on Big Data Applications and Services, 2015
Skyline queries compute data that are not dominated by any other data in the same database. Thus, it can discover user preference points without using scoring functions. Until now a lot of algorithms have been proposed that can solve the given problem in different ways. Sort-Filter Skyline (SFS) algorithm first makes sorting on data, which is conducted

The Skyline of a Probabilistic Relation

IEEE Transactions on Knowledge and Data Engineering, 2013
In a deterministic relation R, tuple u dominates tuple v if u is no worse than v on all the attributes of interest, and better than v on at least one attribute. This concept is at the heart of skyline queries, that return the set of undominated tuples in R.
