4.4.1 Using Gold-standard Syntax To understand the upper-bound performance of the syntax-aware approaches, we use the gold-standard dependency trees as the input and apply the TPF approach. The TPF method with gold-standard parse trees brings a very large improvement of 6.7 in F1 (combined) over the baseline without using ELMo, and 5.1 when using ELMo. This shows the usefulness and great potential of syntax-aware SRL approaches.
