In principle , this might be done by providing the generator with vague input -- in which case no special algorithms are needed -- but suitably contextualized vague input is often not available ( Mellish 2000 ) .
understanding shortcuts in nlg systems

If the usefulness of NLG resides in its ability to present data in human-accessible form , then vagueness must surely be one of its central instruments , because it allows the suppression of irrelevant detail . In principle , this might be done by providing the generator with vague input -- in which case no special algorithms are needed -- but suitably contextualized vague input is often not available ( Mellish 2000 ) . The only practical alternative is to provide the generator with `` crisp '' ( i.e. , quantitative ) input , allowing the generator to be hooked on to a general-purpose database .
