We present a novel approach for find- ing discontinuities that outperforms pre- viously published results on this task. Rather than using a deeper grammar for- malism, our system combines a simple un- lexicalized PCFG parser with a shallow pre-processor. This pre-processor, which we call a trace tagger, does surprisingly well on detecting where discontinuities can occur without using phase structure information.
