A Two-level Spatial In-Memory Index
Dimitrios Tsitsigkos, Konstantinos Lampropoulos, Panagiotis Bouros +2
Very large volumes of spatial data increasingly become available and demand effective management. While there has been decades of research on spatial data management, few works con…
Parallel In-Memory Evaluation of Spatial Joins
Dimitrios Tsitsigkos, Panagiotis Bouros, Nikos Mamoulis +1
The spatial join is a popular operation in spatial database systems and its evaluation is a well-studied problem. As main memories become bigger and faster and commodity hardware s…
Finding k-Dissimilar Paths with Minimum Collective Length
Theodoros Chondrogiannis, Panagiotis Bouros, Johann Gamper +2
Shortest path computation is a fundamental problem in road networks. However, in many real-world scenarios, determining solely the shortest path is not enough. In this paper, we st…
Set Containment Join Revisited
Panagiotis Bouros, Nikos Mamoulis, Shen Ge +1
Given two collections of set objects and , the set containment join returns all object pairs such that . Bes…
