An iterative approach for joint dependency parsing and semantic role labeling
Qifeng Dai, Enhong Chen, Liu Shi · 2009
We propose a system to carry out the joint parsing of syntactic and semantic dependencies in multiple languages for our participation in the shared task of CoNLL-2009. We present an iterative approach for dependency parsing and semantic role labeling. We have participated in the closed challenge, and our system achieves 73.98% on labeled macro F1 for the complete problem, 77.11% on labeled attachment score for syntactic dependencies, and 70.78% on labeled F1 for semantic dependencies. The current experimental results show that our method effectively improves system performance.
