The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:
Query Operators and Systems for the Mobile Big Data Era
Speaker: Demetris Zeinalipour
Big data architectures have transformed the way enterprises collect, store and analyze massive amounts of spatio-temporal data from the mobile workforce. In this talk, I will present operators and systems for querying and managing such Mobile Big Data (MBD), that address challenges of performance, privacy, utility and network efficiency. I will start out by overviewing Anyplace, our Internet-based Indoor Navigation service that won several international research awards for its accuracy and utility. Particularly, I will discuss the challenges in prefetching and privacy-aware data processing of Indoor MBD (e.g., Wi-Fi and magnetic signals). My talk will be succeeded by a summary of Rayzit, which is an award-winning location-based crowd messaging service that allows a mobile crowd to instantly connect to its k Nearest Neighbors (kNN) as they move in space. I will particularly focus on Spitfire, which is a distributed algorithm that provides a scalable and high-performance All k Nearest Neighbor processing operator to Rayzit. I will then overview Spate, which is a novel spatio-temporal data processing and analytic system for telecommunication data (e.g., CDR and MR), which makes compression and decaying a first-class citizen. Finally, I will be concluding with an outlook to our current and future research agenda.
Demetris Zeinalipour is an Assistant Professor of Computer Science at the University of Cyprus, where he founded and directs the Data Management Systems Laboratory (DMSL). He holds a Ph.D. (2005) and M.Sc.
