An Experimental Evaluation and Investigation of Waves of Misery in R-trees
Lu Xing, Eric Lee, Tong An +5
Waves of misery is a phenomenon where spikes of many node splits occur over short periods of time in tree indexes. Waves of misery negatively affect the performance of tree indexes…
SWARM: Adaptive Load Balancing in Distributed Streaming Systems for Big Spatial Data
Anas Daghistani, Walid G. Aref, Arif Ghafoor +1
The proliferation of GPS-enabled devices has led to the development of numerous location-based services. These services need to process massive amounts of spatial data in real-time…
LocationSpark: In-memory Distributed Spatial Query Processing and Optimization
Mingjie Tang, Yongyang Yu, Walid G. Aref +3
Due to the ubiquity of spatial data applications and the large amounts of spatial data that these applications generate and process, there is a pressing need for scalable spatial q…
Pattern-Driven Data Cleaning
El Kindi Rezig, Mourad Ouzzani, Walid G. Aref +2
Data is inherently dirty and there has been a sustained effort to come up with different approaches to clean it. A large class of data repair algorithms rely on data-quality rules…
FAST: Frequency-Aware Spatio-Textual Indexing for In-Memory Continuous Filter Query Processing
Ahmed R. Mahmood, Ahmed M. Aly, Walid G. Aref
Many applications need to process massive streams of spatio-textual data in real-time against continuous spatio-textual queries. For example, in location-aware ad targeting publish…
