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 ...

Continuous monitoring of queries over moving objects has become an important topic as it supports a wide range of useful mobile applications. A continuous skyline query involves both static and dynamic dimensions. In the dynamic dimension, the data object not only has a distance from the query object, but it also has a direction with respect to the ...

Location-Dependent Skyline Query
The Ninth International Conference on Mobile Data Management (mdm 2008), 2008Given a set of data points with both spatial coordinates and non-spatial attributes, point a location-dependently dominates point b with respect to a query point q if a is closer to q than b and meanwhile a dominates b. A location- dependent skyline query (LDSQ) issued at point q is to retrieve all the points that are not location-dependently dominated

Given a set S of sites and a set O of objects in a metric space, the Optimal Location (OL) problem is about computing a location in the space where introducing a new site (e.g., a retail store) maximizes the number of the objects (e.g., customers) that would choose the new site as their "preferred" site among all sites.

Proceedings of the 27th ACM International Conference on Information and Knowledge Management, 2018
The range skyline query retrieves the dynamic skyline for every individual query point in a range by generalizing the point-based dynamic skyline query. Its wide-ranging applications enable users to submit their preferences within an interval of 'ideally sought' values across every dimension, instead of being limited to submit their preference in ...

Skyline and reverse skyline query processing in SpatialHadoop
Data & Knowledge Engineering, 2019Abstract 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 ...

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 ...

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.

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
