Translation from narrative text to standard codes variables with Stata
Abstract. In this article, we describe screening, a new Stata command for data
management that can be used to examine the content of complex narrative-text
variables to identify one or more user-defined keywords. The command is useful
when dealing with string data contaminated with abbreviations, typos, or mistakes.
A rich set of options allows a direct translation from the original narrative string
to a user-defined standard coding scheme. Moreover, screening is flexible enough
to facilitate the merging of information from different sources and to extract or
reorganize the content of string variables.
