Examples of simplenlg.framework.NLGFactory

simplenlg.framework.NLGFactory

This class contains methods for creating syntactic phrases. These methods should be used instead of directly invoking new on SPhraseSpec, etc. The phrase factory should be linked to s lexicon if possible (although it will work without one)
