Software testing and the naturally occurring data assumption in natural language processing
Kevin Bretonnel Cohen, William A. Baumgartner, Lawrence Hunter · 2008
It is a widely accepted belief in natural language processing research that naturally occurring data is the best (and perhaps the only appropriate) data for testing text mining systems. This paper compares code coverage using a suite of functional tests and using a large corpus and finds that higher class, line, and branch coverage is achieved with structured tests than with even a very large corpus.
