A new well-formedness criterion for semantics debugging

Dan Flickinger, Alexander Koller, and Stefan Thater

In Proceedings of the 12th International Conference on Head-Driven Phrase Structure Grammar (HPSG), Lisbon, 2005.

We present a novel well-formedness condition for underspecified semantic representations which requires that every correct MRS representation must be a net. We apply this condition to identify a set of eleven rules in the English Resource Grammar (ERG) with bugs in their semantics component, and thus demonstrate that the net test is useful in grammar debugging. In addition, we show that a partly corrected ERG derives 3% less non-nets on the Rondane treebank and we expect that after completing the correction of the ERG, only 5.5% non-nets are derived, which we take as support for our initial hypothesis.
