Title A High-Performance Syntactic and Semantic Dependency Parser
Venue International Conference on Computational Linguistics
Session System Demonstration
Year 2010

This demonstration presents a high- performance syntactic and semantic de- pendency parser. The system consists of a pipeline of modules that carry out the to- kenization, lemmatization, part-of-speech tagging, dependency parsing, and seman- tic role labeling of a sentence. The sys- tem’s two main components draw on im- proved versions of a state-of-the-art de- pendency parser (Bohnet, 2009) and se- mantic role labeler (Bj¨orkelund et al., 2009) developed independently by the au- thors. The system takes a sentence as input and produces a syntactic and semantic anno- tation using the CoNLL 2009 format. The processing time needed for a sentence typ- ically ranges from 10 to 1000 millisec- onds. The predicate–argument structures in the final output are visualized in the form of segments,...
