Abstract
In this paper we present our syntactic and semantic dependency parsing
system submitted to both the closed and open challenges of the CoNLL
2009 Shared Task. The system extends the system of (Zhang, Wang &
Uszkoreit, 2008) in the multilingual direction, and achieves 76.49
average macro F1 Score on the closed joint task. Substantial
improvements to the open SRL task have been observed that are
attributed to the HPSG parses with hand- crafted grammars.
