Human Sensor Networks for Improved Modeling<br>
of Natural and Human-Caused Disasters<br>

This talk will discuss the importance of different roles that social<br>
media can play in management, monitoring, modeling and mitigation of<br>
natural and human-caused disasters. We will present a novel approach<br>
that views social media data as a human sensor network. These data can<br>
serve as a low-cost augmentation to an observing system, which can be<br>
incorporated into geophysical models together with other scientific<br>
data such as satellite observations and sensor measurements. As a use<br>
case scenario, we analyze the Deepwater Horizon oil spill disaster. We<br>
gather the social media data that mention sightings of oil from<br>
Flickr, geolocate them, and use them as boundary forcings in the<br>
General NOAA Oil Modeling Environment (GNOME) software for oil spill<br>
predictions. We show how social media data can be incorporated into<br>
the GNOME model to obtain improved estimates of the model parameters<br>
such as rates of oil spill, couplings between surface winds and ocean<br>
currents, diffusion coefficient, and other model parameters. Other<br>
social media mining and citizen science projects performed by groups<br>
outside of UMBC, on air quality, earthquakes and the Fukushima<br>
disaster will also be summarized as related work.<br>

Oleg Aulov received B.S. degree in mathematics from the University of<br>
Central Missouri, Warrensburg, MO, in 2004 and M.S. degree in Computer<br>
Science with a concentration in Computer Security and Information<br>
Assurance from George Washington University, Washington, DC, in<br>
2006. He is currently working toward a Ph.D. degree in the Department<br>
of Computer Science and Electrical Engineering at University of<br>
Maryland, Baltimore County, Baltimore, MD. His topics of interest<br>
include social media mining, citizen science, machine learning, trust<br>
establishment and management, information assurance, and social<br>
engineering.<br>
