Practical grammar-based NLG from examples
David DeVault, David R. Traum, Ron Artstein · 2008
We present a technique that opens up grammar-based generation to a wider range of practical applications by dramatically reducing the development costs and linguistic expertise that are required.Our method infers the grammatical resources needed for generation from a set of declarative examples that link surface expressions directly to the application's available semantic representations.The same examples further serve to optimize a run-time search strategy that generates the best output that can be found within an application-specific time frame.Our method offers substantially lower development costs than hand-crafted grammars for applicationspecific NLG, while maintaining high output quality and diversity.
