What is NLG?
In: Proceedings of Second International Natural Language Generation, New York, USA.
Giving an adequate general definition of the input to natural language generation (NLG), and hence to NL G itself, is a notoriously difficult problem, practically, theoretically and even methodologically. In this paper, we describe our recent experiences of implementing an NL G component of a larger question-answering system, and trying to understand and resolve some of these problems in this context. We examine the whole lifetime of an answer, from internal data structure to final expression as text, and look for characteristics of the processing which might help identify where NL G really begins. On the basis of this analysis we propose
some principles to inform discussions on the scope of NL G as an individuated enterprise.
