Text as Data
An ever increasing share of human interaction, communication, and culture is recorded as digital text. We provide an introduction to the use of text as an input to economic research. We discuss the features that make text different from other forms of data, offer a practical overview of relevant statistical methods, and survey a variety of applications.
The views expressed herein are those of the authors and do not necessarily reflect the views of the National Bureau of Economic Research.
