报告摘要:

The number of worldwide social network users is expected to reach 2.5 billion by 2018 (1/3 of Earth’s population). A tremendous amount of information is being shared everyday on social media sites.  This massive popularity has lends itself to event detection (social gatherings, natural disaster occurrences, and insurgent activities). Spatiotemporal analytics from social media can assist assimilating social media information of interest in targeted geographic regions and to staying informed about emerging issues. We present our work in the area of generating spatiotemporal analytics in terms of geotagging, location recognition, spatiotemporal correlation detection, and event detection from big social media data and outline challenges and opportunities.
