Dependency or Span, End-to-End Uniform Semantic Role Labeling

Understand

Semantic role labeling (SRL) aims to discover the predicateargument structure of a sentence.

• End-to-end SRL without syntactic input has received great attention.
• However, most of them focus on either span-based or dependency-based semantic representation form and only show specific model optimization respectively.
• Meanwhile, handling these two SRL tasks uniformly was less successful.
