We propose a system to carry out the joint pars- ing of syntactic and semantic dependencies in multiple languages for our participation in the shared task of CoNLL-2009. We present an it- erative 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 la- beled F1 for semantic dependencies. The cur- rent experimental results show that our method effectively improves system performance.
