txttool: Utilities for text analysis in Stata
Abstract. This article describes txttool, a command that provides a set of
tools for managing free-form text. The command integrates several built-in Stata
functions with new text capabilities. These latter functions include a utility to
create a bag-of-words representation of text and an implementation of Porter’s
(1980, Program: Electronic library and information systems 14: 130–137) word-stemming
algorithm. Collectively, these utilities provide a text-processing suite
for text mining and other text-based applications in Stata.
