Evaluating and comparing three text-production techniques

What are the benefits of using Natural Language Generation in an industrial application? We have attempt to answer part of this question with a description of an assessment of three techniques for producing multisentential text: semi-automatic fill-in-the-blank interfacing, automatic linguistic-and-templates hybrid generation, and human writing. This assessment used a black-box methodology, with an independent blind-tested jury that gave different quality levels in relation to a set of criteria. The texts used for the assessment were business reply letters.
