Mathematical Modeling of Public Opinion using Traditional and Social Media A Dissertation Presented by Emily Cody to The Faculty of the Graduate College of The University of Vermont In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Specializing in Mathematical Sciences October, 2016 Defense Date: June 2, 2016 Dissertation Examination Committee: Chris Danforth, Ph.D., Advisor Peter Dodds, Ph.D. Josh Bongard, Ph.D. Jennie Stephens, Ph.D., Chairperson Cynthia J. Forehand, Ph.D., Dean of Graduate College Abstract With the growth of the internet, data from text sources has become increasingly available to researchers in the form of online newspapers, journals, and blogs. This data presents a unique opportunity to analyze human opinions and behaviors without soliciting the public explicitly. In this research, I utilize newspaper articles and the social media service Twitter to infer self-reported public opinions and awareness of climate change.
