Revisiting Semantic Role Labeling: Efficient Structured Inference with Dependency-Informed Analysis
Summary
A modernized encoder-based framework for Semantic Role Labeling (SRL) has been introduced, designed to preserve explicit predicate-argument structure while achieving 10 times faster inference compared to traditional systems. This new framework addresses the limitations of older systems, such as those based on AllenNLP, which entered maintenance mode in December 2022 and struggled with evolving encoder architectures. The model, when using BERT-base, achieves comparable predictive performance, with RoBERTa and DeBERTa further enhancing F1 scores. The research also employs a dependency-informed diagnostic methodology to analyze span-level inconsistencies and LLM behavior, revealing that dependency cues primarily improve structural stability. The framework's explicit predicate-argument structure also supports downstream applications like multilingual SRL projection.
Key takeaway
For Research Scientists developing NLP systems, this modernized SRL framework offers a significant speedup in inference while maintaining or improving predictive performance. You should consider integrating this framework to leverage explicit predicate-argument structures, especially if your work involves applications requiring structural stability or multilingual projection, moving beyond older, less compatible systems like AllenNLP.
