Multilingual Dependency-based Syntactic and Semantic Parsing

Our CoNLL 2009 Shared Task system in-cludes three cascaded components: syntactic parsing, predicate classification, and semantic role labeling. A pseudo-projective high-order graph-based model is used in our syntactic de-pendency parser. A support vector machine (SVM) model is used to classify predicate senses. Semantic role labeling is achieved us-ing maximum entropy (MaxEnt) model based semantic role classification and integer linear programming (ILP) based post inference. Fi-nally, we win the first place in the joint task, including both the closed and open challenges. 1 System Architecture Our CoNLL 2009 Shared Task (Hajic ̌ et al., 2009): multilingual syntactic and semantic dependencies system includes three cascaded components: syn-tactic parsing, predicate classification, and semantic role labeling
