1 A CyberGIS Environment for Near-Real-Time Spatial Analysis of Social Media Data
Shaowen Wang CyberInfrastructure and Geospatial Information Laboratory (CIGI) Department of Geography and Geographic Information Science Department of Computer Science Department of Urban and Regional Planning National Center for Supercomputing Applications (NCSA) University of Illinois at Urbana-Champaign NSF-CDI Specialist Meeting Knowledge Discovery in Cyberspace and Big Data San Diego, CA August 7, 2013

2 Cyberinfrastructure – A Simplified View
Data / Information People Integration Collaboration Computing Communication

3 Advanced Cyberinfrastructure Examples

4 CyberGIS – A Tetrahedron View
Data / Information Geo Spatial CyberGIS Computing Communication

5 What is special about “G” in CyberGIS?
Location Place Space Spatiotemporal Integration Synthesis

6

7 Hypothesis: Is such detection feasible based on social media data?
CyberGIS FluMapper Purpose: Early and fine- spatiotemporal-scale detection of flu outbreak Hypothesis: Is such detection feasible based on social media data?

8 Demo

9 Questions – Scientific Problem Solving
How to detect, represent, and communicate spatiotemporal patterns of flu risk? How to reveal spatial diffusion trajectories across various spatiotemporal scales?

Wang, S., Cao, G., Zhang, Z., Zhao, Y., and Padmanabhan, A “A CyberGIS Environment for Analysis of Location-Based Social Media Data.” In: Location-Based Computing and Services, 2nd Edition, ed. A. K. Hassan and H. Amin, CRC Press, pages:

11 FluMapper Components Data collection and processing
Collects, processes and stores streaming data from Twitter in near real time Scalable services to query raw and derived data Spatiotemporal data model Provides aggregated data and statistics at multiple scales for efficient information retrieval At the finest scale, the conterminous United States is represented as a field of 30-arc second resolution Exploratory data analysis Kernel density estimation (KDE) Monte-Carlo simulations Flow mapping Single-source flow mapping is applied to depict movement patterns

12 Spatiotemporal Data Cube
(May 23 ~ June 5, 2013)

13 A 2D Illustrative Example

14 Questions – CyberGIS How to model and analyze big data that are not collected for the purpose of intended spatiotemporal analysis? How to integrate hybrid spatiotemporal analyses? How to replicate and validate such analyses? What are the key CyberGIS characteristics? What are the basic building blocks of CyberGIS?
