Remarks on the Transfer System

Robustness

The fact that predicates in the input to the transfer system to which no rule applies remain in the output could be a source of robustness in an eventual complete tranlation system because it leaves open the possibility that unrecognized words and phrases in the source text should appear in the translation in their original form.  This is not possible at present because of properties of the generator, notably concerning how the morphology of unknown words should be handled.
