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 (Hajiˇc et al., 2009): multilingual syntactic and semantic dependencies system includes three cascaded components: syn- tactic parsing, predicate classification, and s...
