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) wordstemming algorithm. Collectively, these utilities provide a text-processing suite for text mining and other text-based applications in Stata.
