Abstract

A new kind of scientific endeavor -- computational social science -- is emerging at the intersection of social science and computer science. The field draws from a rich base of existing theory from psychology, sociology, economics, and other social sciences, as well as from the formal languages and algorithms of computer science. The result is an unprecedented opportunity to revolutionize the social sciences, expand the reach and impact of computer science, and enable decision-makers to understand the complex systems and social interactions that we must manage in order to address fundamental challenges of economic welfare, energy production, sustainability, health care, education, and crime.

In this talk, I will describe a project underway in my research group to develop and apply new formal languages and algorithms for discovering cause-and-effect dependencies in large social science data sets. I will use an extended historical example demonstrating the opportunities and challenges presented by the complex data sets generated by social systems. I will also describe several modern applications such as detecting stock fraud and understanding the incentive structures in online communities.
