Skyline operation is typical multicriteria decision making well documented in data engineering. The assumption of skyline operation is settled human preference, which may be subject to huge challenges in practical decision-making applications because it simplifies preference scenarios that are usually dynamic. This study establishes the mathematical formulation of dynamic preference in real set...

This paper is dedicated to the problem of automatic skyline extraction in digital images. The study is motivated by the needs, expressed by urbanists, to describe in terms of geometrical features, the global shape created by man-made buildings in urban areas. Skyline extraction has been widely studied for navigation of Unmanned Aerial Vehicles (drones) or for geolocalization, both in natural an...

Quality web service discovery requires narrowing the search space from an overwhelming set of services down to the most relevant ones, while matching the consumer’s request. Today, the ranking of services only considers static attributes or snapshots of current attribute values, resulting in low-quality search results. To satisfy the user’s need for timely, well-chosen web services, we ought to...

Ranking the Skyline The skyline operator maps a finite set O of objects, each characterized in terms of a fixed number of features (criteria), to the subset of Pareto-optimal elements:

Cloud computing has experienced rapid growth in recent years and become a critical paradigm. Combining multiple cloud services to satisfy complex user requirements research hotspot computing. Service composition multi-cloud environments is characterized by high energy consumption, which brings attention the importance of consumption cross-cloud service composition. Nonetheless, prior mainly foc...

The continuous within skyline query is an important type of location-based query, which can provide useful skyline object information for the user. Previous studies on processing the continuous within skyline query focus exclusively on a static road network, where the object attributes and the conditions of roads remain unchanged. However, in real-world applications, object attributes and road ...
