Dependency and Span, Cross-Style Semantic Role Labeling on PropBank and NomBank
Table 3: The different syntactic contribution to span-based and dependency-based SRL with end-to-end setup using predicted syntax and BERT pretrained LM features.

In order to assess the effect of our proposed two syntax aided methods to the span-based SRL and dependency-based SRL respectively, we conducted an ablation study on WSJ test set with end-to-end setup using predicted syntax and BERT pretrained language model (LM) features to explore how the different syntax (constituency and dependency) impact our model. This shows that our two syntactic enhancements are effective.
