Data ex Machina: Introduction to Big Data

Abstract

Social life increasingly occurs in digital environments and continues to be mediated by digital systems. Big data represents the data being generated by the digitization of social life, which we break down into three domains: digital life, digital traces, and digitalized life. We argue that there is enormous potential in using big data to study a variety of phenomena that remain difficult to observe. However, there are some recurring vulnerabilities that should be addressed. We also outline the role institutions must play in clarifying the ethical rules of the road. Finally, we conclude by pointing to a few trends that are not yet common in research using big data but will play an increasing role in it. Expected final online publication date for the Annual Review of Sociology Volume 43 is July 30, 2017. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
