  Text analysis is the process of constructing structured data from
unstructured textual content, usually implemented in Python. In terms of the
principles of text analysis, a computer program with the ability to read a file
and match it with a regular expression is all that is needed for basic text
analysis. However, few researchers have used Stata as their main text analysis
tool. In this paper, I will take a step-by-step approach to the practical
process, giving examples of how text analysis can be performed with Stata, and
comparing the code and running time with Python.
