Research on multiple enhanced k combination reverse Skyline query method

Journal of Big Data
The reverse Skyline query aims to identify a set of data points that dynamically dominate a query point from the decision-makers’ perspective. It has been widely applied in business decision-making, recommendation systems, location-based services ...

A novel multi-objective SKG-skyline algorithm integrating spatial keyword data transformation

Complex & Intelligent Systems
The spatial keyword skyline query effectively addresses user preferences, particularly for location-based service applications. However, existing approaches primarily focus on single-object queries and remain unsuitable for group-based computations.

Privacy-Preserving Secure Computation of Skyline Query in Distributed Multi-Party Databases

Information, 2019
Selecting representative objects from a large-scale database is an essential task to understand the database. A skyline query is one of the popular methods for selecting representative objects. It retrieves a set of non-dominated objects.

Skyline computation for frequent queries in update intensive environment

Journal of King Saud University: Computer and Information Sciences, 2016
The skyline queries produce the tuples which are ‘promising’ on the dimensions of the user’s interest. The popular datasets often get queried by the users where dimensions of the user queries often overlap.

An efficient approach towards index structures for skyline queries

Journal of King Saud University: Computer and Information Sciences
Given a multidimensional dataset, the skyline query is to find all objects that are not dominated by any other object in the dataset. This query represents a multi-objective optimization approach that is used extensively in various areas such as data ...
