TITLE | Geolocated Online Datasets and the Study of Human Behavior
ABSTRACT | The growing diffusion of GPS enabled cell phones coupled with the widespread adoption of social networking tools is opening up new avenues for the study of human behavior. Using a large dataset of geolocated Tweets we present an analysis of both at the temporal and spatial aspects of human communication and interaction. By coupling the analysis of geocoded tweets over a period of two years with tools for automatic language detection we are able to present a large scale study of the geography of language use around the world at scales ranging from country to neighborhood level and how it varies over the course of a year due to seasonal variations of tourism. Finally, we show how the volume of information available in online systems permits the real time gathering of quantitative indicators anticipating the future unfolding of opinion formation events.
BIOGRAPHY | Bruno Gonçalves is a faculty member at Aix-Marseille Université with a strong expertise in using large scale datasets for the analysis of human behaviour. After completing his joint PhD in Physics, MSc in C.S. at Emory University in Atlanta, GA in 2008 he joined the Center for Complex Networks and Systems Research at Indiana University as a Research Associate. From September 2011 until August 2012 he was an Associate Research Scientist at the Laboratory for the Modeling of Biological and Technical Systems at Northeastern University. Since 2009 he has been pursuing the use of Data Science and Machine Learning to study human behavior. By processing and analyzing large datasets from Twitter, Wikipedia, web access logs, and Yahoo! Meme he studied how we can observe both large scale and individual human behavior in an obtrusive and widespread manner. The main applications have been to the study of Information Diffusion, Behavioral Change and Epidemic Spreading. He is the author of over 40 publications and the editor of the forthcoming book Social Phenomena: From Data To Models (Springer, 2014).
