The low thread-level accuracy across all the systems prove that reconstructing an entire tree is a difficult task. Models are reasonably accurate at the edge level. Our coherence model shows promising results, yielding substantial improvements over the baselines. It delivers 2.7% improvements in thread-level and 2.5% in edge-level accuracy over the best baseline (COS-sim).
